In recent years, the GMC Acadia has become one of General Motor’s most popular models. The midsize SUV is exceptionally versatile, with room for up to seven passengers and available all-wheel drive. Sadly, it’s been plagued by low reliability since its introduction in 2007. First generation models suffer from transmission problems, timing chain failures, oil leaks – you name it. When GM introduced the redesigned, second-generation Acadia in 2017, the hope was that the SUV’s reliability would improve. But after just a year in production, the vehicle is already dogged by mechanical and electrical issues. According to the National Traffic Highway Safety Administration (NHTSA) website, the main problem areas are the transmission, electrical system, and exterior lighting

Transmission – Acadia Shift To Park Warning

When you park your car, you’re ready to exit and go about your business. But the 2017 GMC Acadia doesn’t understand that. The vehicle’s onboard computer fails to recognize when the transmission has been put in park. As a result, it keeps all of the interior electronics running – the dashboard, radio, etc.

On Edmunds.com, one owner complains, “2017 Acadia. Shift to park problem that does not allow the car electronics to turn off. Must restart several times and wiggle the stick forward and backward to eventually correct. GM knows the problem and does nothing to correct saying they are working on what to do. No concern for the continuous problem the customer must be frustrated with on a daily basis. No effort to replace the shifting mechanisms. So just wait and live with it. Unacceptable. Do not buy this car. Most all other cars stick shift mechanisms work properly.”

General motors has released a technical service bulletin (TSB) regarding the problem. In the TSB (PIT5616A), the automaker states, “Condition: Vehicle displays Shift to Park message on DIC when in Park. Vehicle may not shut off when put in Park or may not start.”

So, what’s the cause and subsequent fix? Right now, GM doesn’t have one (very reassuring). It lists the cause of the problem as “unknown at this time.”

Here are some actual complaints logged with the NHTSA about the 2017 GMC Acadia Transmission Problems

A MESSAGE SHIFT TO PARK KEPT APPEARING WHEN THE CAR WAS IN PARK AND SHUT OFF. THEN I PUT THE CAR IN REVERSE AND THE ENTIRE CARE LOCKED UP. (A MESSAGE FROM GMC -GENERAL MOTORS LLC (GM) IS RECALLING CERTAIN 2018 CHEVROLET EQUINOX AND GMC TERRAIN VEHICLES AND 2017-2018 GMC ACADIA VEHICLES. THE RIGHT FRONT INTERMEDIATE DRIVESHAFT MAY FRACTURE AND SEPARATE WHILE DRIVING.)

WHEN THE VEHICLE IS IN PARK AND YOU TRY TO TURN IT OFF WITH THE START/STOP BUTTON AN ON DASH ERROR CODE OF “SHIFT TO PARK” APPEARS EVEN THOUGH THE VEHICLE IS CLEARLY IN PARK. YOU ARE NOT ABLE TO TURN THE VEHICLE OFF. I TOOK THE VEHICLE IN FOR SERVICE ON 6/4/18 AND WAS TOLD THAT GM IS AWARE OF THE ISSUE HOWEVER THEIR ENGINEERS HAVE NOT FOUND A SOLUTION. THIS CURRENTLY IS FORCING ME RESTART THE ENGINE, PUT MY CAR IN REVERSE, SHIFT BACK IN DRIVE, TRY RE PARKING AND TURNING OFF AGAIN REPEATING THE PROCESS UNTIL IT EVENTUALLY TURNS OFF. I DO NOT KNOW IF MY CAR IS TRULY IN GEAR OR NOT. I’M AFRAID THAT IT MIGHT CAUSE A DANGEROUS SITUATION.

MY 2017 GMC ACADIA 6 CYLINDER AWD HAS EXCESSIVE VIBRATIONS THAT OCCUR AT 1400-1600 RPM AND AT VARIOUS SPEEDS.IT SEEMS LIKE THE TRANSMISSION REFUSES TO SHIFT AND IT LASTS FOR UP TO A QUARTER MILE.VIBRATION IS MOST PRONOUNCED AT SPEEDS OF 55-60 MPH THE DEALER DIAGNOSIS SAYS IT IS FUNCTIONING NORMAL. THE STRUTS WERE REPLACE AT1390 MILES AND MOTOR MOUNTS ADJUSTED, PROBLEM REMAINS, AUTO BROUGHT TO DEALER FOR RECALL AS PER BULLETIN 17109 BUT IT STILL VIBRATES EXCESSIVELY. THE LEAD MECHANIC AT THE DEALERSHIP SAID THE AUTO ADJUSTS TO THE DRIVER AND SAID THE VIBRATIONS WILL STOP AT ABOUT 2500 MILES. THE CAR NOW HAS 2900 MILES AND IT STILL FEELS LIKE THE TRANSMISSION IS GOING TO FAIL. THE VIBRATION IS UNCOMFORTABLE AND ALTHOUGH THE DEALERSHIP SAID THE CAR IS SAFE IT DOES NOT FEEL SO.IT SEEMS IMPOSSIBLE FOR A VEHICLE TO BE FUNCTIONING PROPERLY WITH THIS CONTINUAL ERRATIC VIBRATIONS..

Electrical system

Today’s vehicles have dozens of computers and miles of wiring onboard. With such complexity, electrical gremlins are bound to pop up when vehicles aren’t engineered to perfection. Case in point: the 2017 GMC Acadia. Although the SUV is only about a year old, it’s electronics are already on the fritz.

Of all the digital devices found on the vehicle, so far, the electronic parking brake seems to be one of the most problematic.

One owner, from Great Falls, MT, wrote into the NHTSA website, “After releasing electronic parking brake, the service parking brake light comes on and the parking brake light flashes. Parking brake is no longer operational.”

GM has released a TSB (17-NA-002) to address the concern. It reads:

“Some customers may comment on one or more of the following conditions: amber electric park brake light is on, amber electric park brake light is flashing, parking brake is inoperable.The technician may find the following DTCs set:C028F 04, C1586 04.”

According to the automaker, the problem is software in the parking brake’s computer (referred to as a module). Re-flashing the unit is supposed to cure the concern.

Another problem area is the horn. According to owners, it takes an excessive amount of effort to depress and activate.

On the Edmunds website, an owner complains, “Horn does not operate with normal driver pressure. Requires two hands. Try that when you NEED it. A definite safety issue that the dealer recognized but could not fix. No fix from GM. Needs to be recalled. Other Denalis on the lot were the same, and this problem has been reported by several others and also to the NHTSA.”

There is a supposed fix now– GM has a TSB (17-NA-367) regarding this issue. The document states, “Some customers may comment on the high effort required to sound the horn.”

Dealers have been instructed to replace the steering wheel wiring harness with an updated unit to correct the concern.

Here are some actual complaints logged with the NHTSA about the 2017 GMC Acadia Electrical Problems

HORN IS NEARLY IMPOSSIBLE TO OPERATE UNDER ANY CONDITIONS. IT TAKES TWO HANDS TO MAKE IT WORK AND ONLY WITH EXCESSIVE FORCE, AND IN ONLY ONE SPOT ON THE STEERING WHEEL. RECENTLY I WAS ALONGSIDE OF A BIG RIG AND THE DRIVER DID NOT SEE ME. HE STARTED TO MANEUVER INTO MY LANE AND THE ACADIA HORN WOULD NOT WORK. NEARLY CAUSED A MAJOR ACCIDENT ON A 70MPH POSTED HIGHWAY. THE DEALER KNOWS ABOUT THE PROBLEM AND IT HAS BEEN REPORTED TO GMC AND NHTSA BY MANY 2017 GMC ACADIA OWNERS. TO DATE, GMC OFFERS NO FIX FOR THIS PROBLEM. A RECALL OR AT LEAST A REPAIR BULLETIN NEEDS TO BE ISSUED BEFORE SOMEONE GETS HURT, OR WORSE. THIS IS A WIDESPREAD SAFETY ISSUE WITH THE 2017 GMC ACADIA, AND POSSIBLY THE 2018 GMC ACADIA IF THE SAME HORN ACTIVATION HARDWARE IS USED IN THE NEWER MODEL.

NEW 2017 GMC ACADIA DENALI FWD. LESS THAN 100 MILES. HORN DOES NOT OPERATE WITH NORMAL DRIVER PRESSURE UNDER ANY CONDITIONS. REQUIRES EXCESSIVE PRESSURE TO OPERATE, REQUIRING USING BOTH HANDS AND THEN ONLY IN ONE SPOT. GM IS AWARE OF THE PROBLEM AND HAS DONE NOTHING TO CORRECT, CALLING IT IS OPERATING “AS DESIGNED”. THE DESIGN IS FLAWED AND GM FAILS TO ADMIT IT AND TAKE CORRECTIVE ACTION. IT IS PAST TIME THAT THIS PROBLEM IS FIXED, AS IT HAS BEEN REPORTED MANY TIMES BY OTHER GMC ACADIA OWNERS AND IS ON RECORD WITH THE NHTSA. DOES SOMEONE HAVE TO BE KILLED BEFORE A FIX IS RELEASED? DOES SOMEONE HAVE TO BE KILLED BEFORE THE NHTSA ACTS ON THIS POTENTIALLY LETHAL DEFECT?

AFTER RELEASING ELECTRONIC PARKING BRAKE, THE SERVICE PARKING BRAKE LIGHT COMES ON AND THE PARKING BRAKE LIGHT FLASHES. PARKING BRAKE IS NO LONGER OPERATIONAL.

Exterior lighting

Functional headlights are an important feature for a vehicle to have. Yet, many owners complain the 2017 Acadia’s lamps either aren’t bright enough or don’t work at all.

An owner from Baldwinsville, NY, says on the NHTSA website, “Headlights are dim to the point of being dangerous. Dealer confirms that all 2017 Acadia are like this. This is by no means the first complaint about this issue. An accident waiting to happen.”

Another, on Edmunds, states, “Driving at night the headlights are not bright, need the fog lights to help, and you have to always turn them on. I’m try to get out of this lease now. Will never by a GM product again.”

So far, there has been no TSB or recall from GM addressing the headlight concern.

Here are some actual complaints logged with the NHTSA about the 2017 GMC Acadia Exterior Lighting Problems

HEADLIGHTS ARE DIM TO THE POINT OF BEING DANGEROUS. DEALER CONFIRMS THAT ALL 2017 ACADIA ARE LIKE THIS. THIS IS BY NO MEANS THE FIRST COMPLAINT ABOUT THIS ISSUE. AN ACCIDENT WAITING TO HAPPEN.

AS MUCH AS I LOVE THE VEHICLE AS A WHOLE, IT UNFORTUNATELY HAS THE WORST HEADLIGHTS I HAVE EXPERIENCED IN ANY VEHICLE THAT I HAVE EVER DRIVEN. AS SOMEONE WHO HAS PERFECT VISION, I OFTEN FIND MYSELF SQUINTING TO SEE THE ROAD AHEAD OF ME AND VARIOUS SIGNS. IT HAS GOTTEN TO THE POINT WHERE I HAVE RESORTED TO DRIVING WITH MY HIGH BEAMS ON, JUST SO I CAN SEE WHERE I’M GOING IN CITY STREETS, HIGHWAY DRIVING, AND MAKING TURNS. I’VE NEVER HAD THIS ISSUE WITH ANY OTHER VEHICLE THAT I HAVE DRIVEN AND THE UNFORTUNATE THING IS THAT MY FATHER HAS NEARLY THE SAME IDENTICAL VEHICLE AS ME AND IS EQUALLY DISSATISFIED WITH THE HEADLIGHTS. I WOULD CONSIDER THESE AS DANGEROUS AS ANYTHING TO DRIVER, PEDESTRIAN, AND PROPERTY RELATED SAFETY. I WOULD STRONGLY URGE THAT IF GM DOES NOT STEP UP AND CORRECT THIS DANGEROUS OBSTACLE TO MY LIFE, THEN I WOULD STRONGLY URGE AN INVESTIGATION AND AN IMMEDIATE RECALL OF THIS VEHICLE BY THIS ORGANIZATION

I ALMOST HIT A PEDESTRIAN WALKING ACROSS THE STREET IN FRONT OF MY CAR AT NIGHT AS I DID NOT SEE HIM DUE TO,THE HEADLIGHTS BEING TOTALLY INADEQUATE TO SEE IN FRONT OF THE CAR AND THE LIGHTS HAVE A BLIND SPOT WHEN ILLUMINATED AS THE DO NOT SHINE HIGH ENOUGH. THERE IS LIKE A SHELF EFFECT THAT WON’T ILLUMINATE ABOVE FOUR FEET OF THE ROAD IN FRONT OF YOU. ALSO THE LIGHT DOES NOT ILLUMINATE THE ROAD ENOUGH ESPECIALLY IN WET CONDITIONS. IT IS LIKE HAVING NO,LIGHT AT ALL.

Every time I take it to stoops they have it for a couple days and I'm out of a car which means no transportation for work and within 10 days after I get it back the same issue appears. The car sounds like it's going to shut off at any given time I'm driving. It shutters while at a light or in a restaurant line. It drives smooth but when I shut the car off it makes a whiny noise sometimes.

I own a 2017 acadia denali (purchased 10-4-17) we started having trouble with the vehicle in that a message appeared saying to shift the car into park. It would shut off but the lights and radio would stay on and you couldn't lock the vehicle. I took it to ferman gmc in wesley chapel on may 28th of 2019. Supposedly they could not replicate the issue. The problem continued and we took it in again on may 31st of 2022. Again, they couldn't replicate what we were encountering. Now it's getting worse, happens almost every time we use the vehicle. So back to ferman yet again (oct 12th 2022). Now they are aware of said problem (code is b000a park switch circuit open). At this time they installed an sl-n-switch and n-harness at a cost of . 13. Then labor, shop fees and taxes brought the total to 0. 91, out of my pocket for a known problem. We have also come across a class action suit identifying this as a problem. And a tsb is also out there titled 'vehicle displays shift to park message on dic when in park. Vehicle may not shut off when put in park or may not start". There is a nhtsa id number for this issue: 11353147

Purchased the vehicle in october 2017 with 7,408 miles on it. In 2019 started to receive a warning when the car was in park and I was shutting it off that said “shift to park”. The vehicle would not allow itself to shut off. I took it to our dealer and they replaced the shifter. The mileage at the time was 12,974. This week the “shift to park” message has now begun to pop up again and today I was unable to turn the vehicle off for quite some time as I had to keep shifting it in and out of park for the computer to respond. The car is shifted completely in to park and it shows a p on the console screen, however still is not recognizing that is in park. I only have put 15,000 miles on it over the past three years so there is no reason for it to have failed. It is scary and dangerous to be unable to shut your vehicle off. Especially when you are stuck in your garage or away from home with your little one.

The 2017 gmc acadia has a known problem when shifting to park. The computer system does not acknowledge the vehicle is in park. It requires numerous ways to get the vehicle to acknowledge it is in park and shut off: 1) turn the motor on and off and shift from drive to park continuously until acknowledged in park and shuts off (waste of time, gas, and effect on the starter and ignition) 2) bang down on the console shift knob 3) pray this is a known problem with acadia 2017 and 2018. Why has this issue not been addressed for a forced recall by gmc. If you take it to the dealer to fix it is very expensive and their original problem. This is a safety issue shifting from drive to park continuously when stopped. This is not good to have to do especially for senior citizens who might inadvertently drive forward or in reverse when simply trying to stop.

When vehicle is put in park (dash reads park) the vehicle is not detecting the vehicle in park and vehicle will not turn off. It takes multiple attempt moving the gearshift into other gears and then into park before the vehicle registers a "park" and able to turn off the vehicle. If you take your foot off the the break, vehicle doesn't move when park gear not detected. Safety concerns include parking in garage and not realizing the vehicle has not turn off and possibility of co2 or if a child would get in the vehicle possibly being able to engage the gearshift into reverse or drive. This happen 3 out of 4 times when placed in park.

Loss of power steering: bought new late 2017: in 1st month a whining noise was present while turning the steering wheel in any direction (driving or in park) even when slightly turning the wheel. At the time, didn't seem to effect anything. Difficulty started around 80k miles & continued to get worse as time went on. Each time varies on type of turn, speed of turn, how long the car has been in use. On average: it starts (& continues to get worse) after the first 10/15 minutes of driving. Loss of steering comes & goes (not only happening while turning) for at least 4 -15sec. In the last year (mid 2021 - 2022) went to mechanic -couldn't find an issue. Husband checks fluid levels monthly (no changes/no leaks are visible ). As of may 2022 (130k miles) turning into parking lots/spots/driveways/etc I have no power steering, my husband is barley able to turn the wheel during these events. Its unsafe to drive. Doesn't seem to be as bad if speed is 20mph or faster. Shudder issue (maybe @60kmiles): *we had this issue w/our 2012 acadia too. Multiple gmc certified mechanics have been used to correct this. Only one mechanic was able to witness the shuddering. All things tried have failed to correct it. First started happening between 35 - 55mph (now its at any speed: 10 - 80mph), speeding up used to make it shudder less, turning traction control off use to make it shudder less. Plenty of forums abt this issue including all things tried & failed. No resolution. Shudder causes car to not accelerate at times. Rpm jumps high & bounces around. Ac would stop working (started @20k miles) it makes an air releasing noise when ac is in use. *2012 acadia did this too. Adding freon helps for limited time. No leaks. Mechanics "cnd", its still not fixed. "tighten fuel cap" warning comes on randomly. When checked, its tight. Automatic start fails randomly, since day 1. "ck engine" light comes on & off randomly. Main issue was the shuddering *reporting date used for loss of power steering.

Previous complaint of shift to park on 06/13/19 voq 11219862 at mileage 36270. On 12/5/21, approx miles 62099 same problem with shift to park. Was scheduled for service on 12/06/21 at adams buick gmc in richmond, ky and mentioned the problem and previous complaint. Was told that it had been over a year ago but that they could fix it and charge me 2 for part & 5 for labor. It was less that 26000 miles driven since the last issue. After last complaint, the dealer contacted gmc and the part was replaced at no cost under bulletin for concern # 5 145420 and they replaced the transmission control assembly. This is an ongoing problem with gmc and I don't think that every 26000 miles I should have to pay to replace the same part when gmc knows it is a problem by the numerous complaints. In fact while I was getting my vehicle serviced, I spoke to another lady there who had the same problem with her vehicle. Had I not caught the message, I probably would have had to replace my battery or my vehicle could have rolled into the house. There were no warning lamps or messages prior. Gmc needs to step up to the plate and issue a recall because they have numerous vehicles with the same problem. My vehicle has undergone this malfunction twice and I find it unacceptable and know that I can't afford to pay 7 every 26000 miles for an issue that gmc is clearly aware of but won't address because no one has been killed by the issue as of this date to my knowledge, but it's going to happen sooner or later if the issue is not addressed properly.

Vehicle is a 2017 acadia denali with ~39,000 miles. The problem started without any symptoms or warnings in october 2021. The dash gives a "shift to park" message when the shift is moved to the park position and the driver attempts (to turn all systems off so as) to park and exit the vehicle. When the off button is pushed, the "shift to park" message displays. The engine does turn off, but the lighting, radio, etc. Stay on. When opening the door, the vehicle emits tone(s) suggesting the driver is trying to leave the vehicle while it's running and/or has left electrical systems on. Driver is actually attempting to simply turn everything off and park the vehicle. The fact that all the lighting and radio stay on runs down the battery, potentially leaving the driver stranded.

Shift to park light came on when I parked. As I parked, the break pad locked and I could not release it. The shifter locked and I could not release it. It would not let me turn vehicle off. I had to experiment on how to get error message to stop and breaks to unlock so I did result to jiggling the shifter and put car in reverse then in drive and park again and trying to turn off (after doing this atleast 4 times) eventually it unlocked and let me turn car off without getting this error message. This happened 2 years prior and I had my 1 yr old in car with me panicking bc I couldn't drive my car for a bit until the mechanism decided to start working again. This time I knew how to fix it better bc it had happened 2 yrs prior so I knew to wiggle the shifter and try to put it back in drive etc to eventually get car to shut off. There's records of this shift to park being fixed in 2019 and again in 2021. I should not be responsible for paying anything for these issues. It is a gmc malfunction. Although mechanical it is a safety concern of mine too!

Vehicle was purchased used in june 2020 issue #1 after shifting car into park, display will indicate p for park , but also says vehicle is not in park. Since you are not sure if it actually in park and to eliminate this display, you need to restart the vehicle, go thru the gears again and then back into park. This happens several times a week with having to restart and park again up to 10 times before the vehicle will register it is in park. I have read there is a technical service bulletin on this issue as well as a case to get gmc to issue a recall. This is a serious issue because you are unaware if the vehicle transmission is actually in park. Having to restart and continually shift to park is time consuming and quite frankly a nuisance. At this point in time, the only way of correction, other than restarting up to ten times, is to click the gear shift several times after placing in park. This will work 5/10 times. Issue #2 - vehicle does not always detect remote. Have replaced battery in remote 5 times and will last approximately 8-10 weeks. At times, when the vehicle has been driven and is placed into park, the display will read no remote detected. Have also placed remote into pocket into console and will still receive the same no remote detected. Although there is never any indication battery is low or dead on remote, this is also the only possible correction we have found. However, we do believe there must be another correction for this issue.

This vehicle has twice had parts replaced for the "shift to park" issue detailed in gm tsb 19-na-206. The first incident was in april 2019, and it was repaired under warranty at about 24,800 miles. The second incident was this past week at about 50,800 miles, and this repair cost almost 0 to fix. I contacted gm customer support and was told that I could not get any reimbursement because there was no special coverage or recall for this known problem. This is completely unacceptable, since the problem is clearly a defect in parts manufacturing or assembly, and it renders the vehicle completely unusable since it is impossible to turn the car off when the car does not recognize that the shifter is in park. This is a safety issue because the driver needs to be certain whether or not the vehicle is securely parked before leaving the vehicle.

I have experienced the same problem as a multitude of acadia owners as is well publicized via the internet and class action lawsuits, which are now beginning initiation. My dealership tells me they have a lot of customers with the same problem which usually starts when the vehicle has around 15k miles on the odometer. The problem is the intermittent shift to park display on the information center. It tells me that the shifter is not in park position when I go to turn the engine off, but it really is in position. When it happens I cannot turn off the automobile without restarting it. Sometimes it will turn itself off after a few seconds without any intervention on my part, sometimes more, sometimes after I jiggle the shift lever, but many times I have to restart the engine one or more times to turn the vehicle off. If the system can't be sure if I'm truly in park position, how can it be sure that the lever is really engaged which would enable the car to roll away. I have had it back for repair service twice during the bumper to bumper warranty period to resolve the issue based on gmc guidance. That service tends to resolve it for a while but it always comes back again after a period of time. The last time I was told a jumper was installed so I should never get the problem again but it has returned and have had quite a few occurrences over the past two months. There is absolutely no pattern to the problem. What is really frustrating me is that I recently took it back again (after my bumper to bumper warranty was over) and they tell me there is another service bulletin from gmc which says the original shifter cable is too short and they need to install a longer one. Now they want me to pay 5 to install the new cable which is wrong wrong wrong in order to resolve a gmc safety issue which was the result of an original design issue by gmc. I refused as this must be covered by gmc and should be the subject of a government mandated safety recall.

When you put the car in park it often won't recognize it and will display a message on the console stating “shift to park”. When it does this you're not able to turn your car completely off so you just have to continue messing around with the shifter or turning the car back on again by pressing the break until it finally goes off. This happens at least once daily and can take upwards of 5 minutes sometimes to finally recognize the car is in park so you can turn the car off. We've tried leaving the car running before when this message is displayed when it's been parked in our garage thinking it would eventually realize it's in park and shutoff but after 10 minutes of running it still hadn't recognized it was in park. We called our dealership about this and they told us that they get a lot of complaints about this issue.

Shortly after I purchased my acadia in may of 2018, it started displaying a shift to park warning when I would put the car in park. I contacted the dealership and they said it was a known issue and they had to replace the shift assembly. Well about 3 weeks ago it started doing it again. Only this time it's worse. It takes several tries and tricks to get the car to recognize it's in park and allow me to shut the car off - when the warning pops up it won't allow the car to power off so all the electronics stay on. I called the dealership and they told me because my extended warranty expired at 79,000 miles and they had already replaced the shift assembly once that there is nothing they can do and I will have to pay out of pocket for this repair even though it's a well documented issue with these vehicles.

The vehicle gives a 'shift to park' warning on dashboard after vehicle ignition button. This warning shows up every time the vehicle is accepted to shut off. It takes several minutes and tries to get the message to go away and the vehicle to completely shut off. The only successful way of getting the message and vehicle to completely shut off is by wiggling or shaking the gear shifter until it goes away. I have been stranded with children in the vehicle for concerns that the vehicle will roll with the vehicle not registering that it is in park. After researching the vehicle issue further it has been found that other owners with the same year and model have had the same shift to park message and have had their vehicle roll on it's own. The vehicle has gone to the dealership to be fixed but unfortunately because my warranty has expired I am being held responsible for paying to fix this safety issue.

Our car, a 2017 acadia, will not auto start, alarms go off randomly, theft warning comes on and hood open warning comes on every time car is started.. Our determination is the hood latch from other forums which is what the garage also determined. We were told only trucks were being replaced not the cars. We don't feel that this is something we should be paying for since it is out there that many have the problem. The latch causes the theft problem which eventually causes the car not to advance in speed (connecting to theft) and could cause death on a major highway when all cars are going 60 plus and your car won't move. Some people were unable to start their cars. This is major and should be corrected with a recall. This might not seem major but it can be. We became leery in driving the vehicle. I have a teen driver and the hood open warning comes on many times throughout a drive. You can clear it and it reappears whether moving or not. This has been going on with us for a good month. Again, this happens while stationary and moving. It can come on at any speed which is the scary part. We have limited our drive and drive at a controllable speed but that doesn't make it safer. Once we were stationary when the alarms went off and could not clear. All the warnings came on. Couldn't unlock car doors with remote. We should not have to pay for this fix! No recall should have to have a death or injury to become important!

I stepped out and locked the doors. I was talking to my friend's husband for a couple minutes, asking if she was home and if my car was okay where it was parked. I wanted to make sure he was not leaving and was blocked in. I then started walking to the house. I was going to walk in the grass and just go to the front door, but since it started to snow, I walked down the driveway. My vehicle then started rolling down the driveway and knocked me over. It proceeded to drive over me. I know I fell on my stomach, as my hands and knees are pretty bruised and scraped up. As the vehicle proceeded to keep going, I was pushed on my back with the tire resting on my right hip. The gentleman ran up and tried to push the vehicle off of me, but could not push it up hill. Luckily the keys and my phone fell out of my pocket and he was able to start the vehicle and drive it off of me. I know at some point I did hit my head, because the back is really tender today. I did go to urgent care to get x-rays because I do not want to go to the hospital with all the covid cases here in st joseph county. They did scrub all the rocks and dirt out of my back and hip and cleaned up my knees. My ex rays came back with no broken bones and I did not have blood in my urine, but they still recommended that I go to the emergency room. I am not able to walk very well and my hip is very swollen. I contacted the dealership because my car was just in the shop because the shift to park light kept coming on in october and I have my repair order that says the problem was fixed on october 22, 2020, which obviously it was not.

My second issue with the acadia is when you are in cruse control, the car will automatically apply the breaks (abruptly and hard) for no reason.

The 2017 gmc acadia I own will not recognize when the vehicle is in park. It states to move to park to shut the vehicle off when the vehicle is already in park. This happens when trying to shut off the vehicle but I am unable to because of the "shift to park" warning.

The "shift to park" warning message shows up and won't permit car to be shutoff. Vehicle is stopped and at rest and is placed in "park" as designated by shift lever light and dashboard indicators, and the auto door unlock feature activated correctly when placed in park. On 9/21/20, it took me about 10 minutes of trying different positions and by physically moving vehicle to a different parking space . Problem occurs sporadically. This same problem has occurred a total of about 5 times in the last 2 weeks but not as severe as this last time. Vehicle was previously serviced 11/2019, when vehicle was under warranty with 10,062 miles for the same issue in which the dealer replaced a shifter harness. Now, 9/21/20, 10 months later, and 12,400 miles, the same problem has re-emerged. The vehicle is now out of warranty. This is obviously a manufacturing or engineering defect.

Would restart engine, move shifting lever multiple times, and eventually would allow vehicle to be powered off (electrically). Took to dealership and they replaced the shifting lever, reporting the issue was fixed. Two days ago, when parking, the engine shut off, but again received the shift to park notice, with electrical system still on. This time, took my foot off the brake and the car started rolling backwards. Could not restart engine, and shifting lever was stuck in place. Had to set the parking break and wait for a tow truck.

Saturday, the gear shifter showed I was in park, the error message came on, and I started rolling backwards!

I bought my 2017 gmc acadia on august 3, 2020. When I got home I put my vehicle in park and on the screen it said "shift to park." I had parked on a hill and I thought maybe that's what had caused it. So for the next couple weeks it has done the same thing multiple times. I am usually parked and shifting it into park. I have been late to work because I am constantly fighting with the shifter so my car will shut off. I have googled it and there a ton of reviews saying that they are having the same problem as me. I am very disappointed that nothing is being done about this. I paid a lot of money for my vehicle and I'm making a payment on it as well. I have to small children and it's a safety hazard because some has made comments that their vehicle rolls backwards. Something needs to be fixed. Some have had it fixed and two months later it happens again. I have called the gmc dealership near me, corporate, and the dealership I bought it from and they are all looking into the problem. We, as in the people that bought the vehicle, shouldn't have to pay for a mistake the gmc clearly knows about.

The vehicle, when parked, shows a warning that states"action required:shift to park" and the vehicle will not turn off. This has led to the vehicle dying in parking lots, at home, once when on vacation. The shift lever is in park, the dashboard shows that it is in park, and when the engine off button is pressed the vehicle will not turn off and asks the driver to shift the car to park, where it already is. This has been a hazard to our family and our families health as the vehicle will then die eventually because the battery runs out. It is apparent that there is a severe malfunction in the electrical/gearbox/computer system not recognizing where the shifter is at the moment. I would like to add a photo but if I were to turn the car on to take the photo the car likely will not turn off, and then die once again. This has been ongoing for approximately a month to 6 weeks.

My 2017 gmc acadia with 40,000 miles on it has been saying 'shift to park' when I try to turn it off. The only way to get it to turn off and be safely in park is to continuously turn it back on shift to reverse or drive move the car a few feet and try again. It continues to take multiple times and the only thing to 'fix it' gmc claims is to replace a lever and that takes 5-6 hours at 135$ an hour and 2 150$ parts. It is not covered under warranty and is a huge safety issue as you either cannot get the vehicle into park and have it safely stuck or it will continue to stay on and possible roll away. There are hundreds of thousands of forums and posts about this issue and even the people who got it 'fixed' still have issues. It is a safety issue and gmc needs to figure out what is causing it how to fix it and do an emergency recall if they cannot figure it out then they need to fully recall the 17-18 acadias and provide replacement vehicles as this is a major safety risk. I cannot be stuck at a place during a global pandemic because my car is stuck due to an issue that gmc cannot fix.

If the vehicle happens to turn the engine off, with this warning, the electronics stay on and drain your battery unless you start the vehicle and then shift from park to other gears and back to park several times before the engine and electronics will shut off. Dealership told me when we took it the first time that they had several of these replaced already. *tr

When I pull in somewhere and shift my car into park and then go to press the button to turn it off I get an ' action required message' on the cluster to shift to park even though it is in park already and it shows on the cluster that it is in park. I took the car into the dealership to repair the recall and have it serviced while it was there and informed them of the issue and to get them to check it out. They said they were not sure what it was but it kept throwing a low voltage code. But when the battery was checked it was fine. They found a bolt loose or missing on a battery cable at the junction box and replaced it and said that they thought that was the problem. But the problem returned a day later when I was on a trip to nashville. While in nashville I again went to the auto parts store for my daughter and pulled into park and got the same ' shift to park message when I was already in park. The cluster on the dash showed that I was in park. I got out to go ahead and run into the store and when I came out my car had rolled backwards across the parking lot to the curb. Luckily it did not hit anything but the curb and stopped. This problem is so dangerous and concerning to me. It is going back into the dealership to get checked again . I did find a youtube video explaining what the problem was in the shifter and why it was not recognizing that the car was in park. Look in the search bar for gmc acadia shift to park problems. I feel this needs to be a recall so no one else s car ends up hurting someone. I have no video of this happening because the cameras at the auto parts store were not operational and no one was around when it happened to see it but me. *tr

The car would be stationary. I would put it in park and then turn off the car. The dash display showed an error that the car was not in park, even though it was. The car would not completely turn off because of this. I turn the car on and off multiple times, shifting in and out of park. One time, the car had to be turned on and off 10 times before it finally registered that it was in park. The car is stationary the whole time during this process. Eventually, the car would register that it was indeed in park and completely turn off as desired. This would happen almost every time the car was driven and then parked. I called my local gmc dealership explaining this. The service supervisor said this has been a common issue with the shifter/transmission controller on acadias of my year model. My dealership did not have the required parts/harness in stock so we had to wait a week and a half for them to be delivered. The date listed is the day I called the dealership. The issue described had been going on for 3-4 days previous to calling. Attached is a portion of my receipt pertaining to this issue.

Shift to park - this is round two (2) that this has had to be replaced!! This is round two (2) of transmission control replacement - which worries me that other transmission issues will occur. Acadia is "clearly" in park - and yes I learnt your little trick to wiggle and or touch the +/- button on top of the shift stick to get it to comprehend that it is indeed in park. But that only worked a total of three (3) times. First time was in a parking lot that this occurred - second time in a gas station. Having to restart your vehicle and shut it off 10 times just for it to acknowledge it is in park - is humiliating to say the least when you are at a gas station as well as frustrating. You need not to ignore this - as the first time I could not get out of the vehicle. Second time - I was able to - however if one ignores it will end up draining their battery and/or rolling if you are on an incline. Kindly step forward and fix this issue if you want satisfied customers. As I can put only one date - I put the first one 01/13/2020 second replacement 03-21-2020 27,109 miles. Thank you.

Randomly when the car is put into park and the button is pressed to stop the engine a message comes up on dashboard stating shift to park... Sometimes you can wiggle the gear shift and the message goes away, sometimes you must start, move, and stop the car as many as 15 to 20 times to get this to go away. If you exit the car why the message is on dashboard, the horn will chirp at you, and the vehicle is not stable, if it is on a decline it will roll, the radio stays on etc. I found a gm service bulletin regarding this, stating the part to be replaced for the acadia was 13528228. I have scheduled an appt with the local gm dealer to have this looked at. It could potentially be very dangerous given the right scenario, if a kid or someone hopped out of the car and it wasnt in park. The car has 36,000 miles on it.

And initially the dealerships and gmc corporate gave me the runaround with who was paying for the bill which the consumers should not have to deal with. Then the car had a shift to park issue in july 2019 which gmc would not replace at their cost even though they released a notice to the service departments about it because a number of people were having the same issue but never issued a true recall notice because they wanted the consumer to get stuck with the bill. And since then I have had issues with my mirrors not staying programmed and the air venting automatically switching to letting air in from the outside without me changing it.

I attempted to work with gm to have them take the car back early (lease) and the request was recently denied. This is my 3rd acadia and it by far is the most dangerous car I have ever driven. I am now reading about a fuel pump problem that could cause the vehicle to catch on fire, a driveshaft that may separate while driving, and a faulty braking system that could cause the vehicle to lose all braking capability. I do not feel safe having my family in this car and I am requesting your assistance to help me work with gm on a resolution.

Premature tread wear on all 4 tires. Car has 34400 miles on it. Took car in for oil change and asked service department to look at tires. I was told this is a problem seen a lot with 2017 acadias. Service department told me that michelin would pay to replace all 4 tires but would split the cost with me, meaning I have to pay 500-600 dollars for new tires when gmc and michelin know this is an issue. These are 60000 mile tires and should not be worn this badly at 34400 miles. I lease this car and have a year left. I do not feel I should have to pay anything to replace defective tires. I was also told that michelin's offer to split cost is only good until 36000 miles which doesn't give me much time to decide what to do or pursue a more satisfactory resolution. If I don't replace the tires in the next month or so, I will have to pay full cost to replace them later. If I turn the car in early, I have 13 payments left to roll into a new lease which increases my monthly payment significantly. Michelin and/or gm need to do the right thing and put all new tires on at no cost to me.

I have a 2017 gmc acadia sl-2 all terrain with 16,000 miles that was in for service a month ago for the 'shift to park' problem for 2 weeks. Gm would not replace the shift assembly instead a harness was installed. One week later it was back in for service and has been in there for last 10 days for the same problem. I do have a loaner which I appreciate but I want my car repaired. I am told the gm strike is affecting the delay in getting parts to the dealer. I have researched and ascertained that there are 2 different shift assembly replacements. The first fix for this problem was part no. 84159722. The second replacement number is 13528228 which replaces the 84159722. My car needs part no. 13528228 so we have no further issue with the shift to park problem. (if in fact this is a 'fix.')

It will not allow me to turn my car off or exit the vehicle and lock it. In order to circumnavigate the error, I must turn my car back on, shift to drive, shift to park and turn my car back off.

They researched the issue then informed me that gm was aware of the "phantom braking" problem and issued a bulletin to the dealers. They said the way to fix it was to reboot the computer. They would not give me a copy of the bulletin that showed the issue or the fix. Gm knew this was happening in their vehicles and they did not tell the car owners.

The "shift to park" message comes on after I park the car. I have to wiggle the gear shift back and forth to get it to go off or the car stays on electronically. The door locks go on/off (and up and down) while driving (purportedly due to the car going in and out of park while driving) which is a major safety concern. Because it's out of warranty (47,000 miles) my dealership said it would be 0-0 to fix the problem although gmc has put out a bulletin to tell the dealerships how to fix it. This should be a recall due to safety concerns. If the car isn't reading it's in park, it could roll and cause injury and damage. This has happened pretty regularly for 2 weeks going on 3 weeks.

After 2 years of ownership of a new gmc acadia my suv would not shut off once I parked my car. It would not be able to detect that I shifted into park after arriving at my destination. All the electronics would continue to run. I would have have to stay in the car and play with the shifter until the computer finally read that it was in park. After taking the car to the dealership the suv was fixed with an new part that seems to have resolved the problem for now but as far as I am aware gmc is still doesn't know why the problem is being caused so I am waiting to see if it happens again. After getting it fixed now my vehicle gives me another warning every time my "auto engine off" is activated at when I come to a stop. Now I continuously get "stebilititrc" warning every time I stop. They fixed one problem and now I have another.

In order to get this message to go away, I have to move the shifter up and down multiple times. Could take up to 20 min to get the error to go away. I can not leave the vehicle until the error is off because the lights stay on and will drain the battery. I also notice that the vehicle rolls a little more after multiple attempts to get error message off. This is concerning that it may not realize its in park and roll into another vehicle causing damage to both or roll away. I took to my dealer and was told this is a 'known' issue and is not covered under warranty, nor is there a recall. I just paid out of pocket for new tires because gm knew the tires placed were 'wearing' too soon based on mileage. Now, I am being told I will have to pay about 0 to get this fixed. Gm knows of issues and not fixing them is wrong. This is not a new issue, has been listed as complaints for the past year, yet gm has done nothing to fix and continue to make the vehicle with the same issues. Frustrating that I have to spend the money to fix an issue they know about! This needs pushed back to gm to hold them accountable and make this right. The shifter issue should be a recall and fixed.

When shifting the vehicle to park and then shutting off the engine, I get an error message 'action required- shift to park'. The vehicle is already in park! I've had to jiggle the shifter, press the brake while jiggling the shifter, restart the vehicle put in reverse, then back in park, and jiggle some more. The radio and lights (both interior & exterior) will not power off and the door chimes nonstop. This happens randomly and it has been a little over a month since the last incident which occurred two days after I had to replace the battery because I missed the error message heading in to work. The last 2 days my husband has disconnected the battery because nothing will work to power off radio & lights. I've had to replace the battery twice now in a new vehicle leased in 2016. The first time was due to brake recall, my vehicle being the only 2017 gmc acadia denali effected by that recall. The brake lights would remain on because the brake was basically sticking, draining the battery. That issue also disabled the cruise control as that feature is unavailable when breaking! This vehicle also had repair to wiring in driver side door due to water getting into the door frame from outside and corroding wires causing detection issues with the key fob. I could not unlock my doors without removing the key to manually unlock. While in the car wash, the vehicle lost connection with my key and the driver's seat moved all the way back as it would for easy exit which I had disabled. Message stating key not detected wouldi was told a needed a new battery in my fob, dealership replaced, called & said everything was working as it should. They ran the vehicle through the car wash before I arrived to pick up the car. When I tried to unlock the doors, the vehicle would not recognize the fob.

I reported a problem over a year ago, and despite several trips to the dealer, the problem has gotten worse. The vehicle seems to shift to neutral while shifting from 2nd to 3rd gears. This results in a very harsh shift. The main safety issue is that while you are trying to accelerate, your vehicle goes into neutral and you nearly stop. Not only have I been slammed into my seat when it finally catches in the next gear, but I've almost been rear ended multiple times. It is very dangerous.

This has caused a stall and the vehicle to possibly still be in gear when parked leading to a rolling hazard. Has taken as many as 15 times for the vehicle to realize it is in park.

2017 gmc acadia displays "shift to park" when already in park and doesn't allow the vehicle to turn off the electronics. Problem was supposedly fixed under warranty when I took it in to the dealer in july of 2018. Now exactly 1 year later, now out of warranty, the "shift to park" message is happening again after the controller was replaced last year to fix the problem. Now that car is out of warranty, even though its such a common complaint now that gmc is aware of, the dealer is asking me to pay over 0 to fix it again. How do I know it will fix it this time? The last "fix" only lasted a year. Gmc needs to issue a recall and fix their manufacturing defect.

A "shift to park" message shows up after I have already put my vehicle in park which does not allow me to turn my vehicle off completely. I have 53,500 miles on my acadia and had to have a new battery put in last week. A gmc dealership states the part to fix the shift lever is on back order but that they have heard this is a common issue with the 2017 acadia. It is frustrating that gmc is aware there is an issue and that there has been a lawsuit filed regarding this however there has not been a recall issued.

When you tried to turn off the car it says shift to park even though the car is already in park and it shows on the dashboard it's in park and so you cannot turn off the car and the car can roll at the time . You have to start the car on and off and then the horn goes off because the keys are in the car and you have to monkey around with the shift lever moving it back-and-forth pushing the button before it actually car shuts off and it goes into park. This is the gmc issue with their transmission or their computer no customer should have to pay for this fix . This should be especially paid for by gmc when somebody is leasing the vehicle .

Our 2017 gmc acadia denali is experiencing "action required" "shift to park" alert on the dash. The indicator on the dash shows the car is in "p" for park and the shifter is placed into the park position. The only resolve for this error to go away is pushing back and forth on the shifter until finally sometimes up to ten minutes, the system recognized that the car is actually in park. If you do not spend the time to try and make the system recognize that shifter is in the parked position the car will continue to try alert you with dinging inside the car and then honking. This is a known issue to which has been reported by several people upon our investigation after experiencing the problem. The part to which is needed to fix this issue is currently on backorder per our local gmc dealership to which there is no estimated time to receive the part in to resolve our issue. We are being told it could take "weeks" prior to this part being received to fix the issue.

Shift to park issue. When you put the vehicle in park, the vehicle does not recognize that it is in park and displays on the information screen to shift to park. The vehicle will not allow you to turn it off because it thinks the car is not in park when it actually is. This was fixed under warranty for me in 2018 with 14k miles (replaced shifter assembly) and now I have having the same issue at 39k miles. Gm needs to recall these vehicles and have the old shift assembly (p/n 84159722) replaced with the new shift assembly it created in october of 2018 (p/n 13528228) when my vehicle was serviced at 14k miles, it was replaced with the old part number 84159722 which is defective as I am having the same problem again at 39k miles. Now my vehicle is out of warranty and I am going to be expected to pay 0 to have the new shift assembly replaced. This should be a recall because it is a safety issue because it will not allow people to turn off their vehicles all of the way, which quickly drains battery and strands them.

After parking the vehicle, shifting into park and turning off the engine, a warning message appears stating to shift the car into park. The car is in park, but there must be some type of sensor failure. I am prohibited from completing shut down of the vehicle until I clear the warning message. When this issue first arose, I could "jiggle" the shifter a bit, and the message would clear. Now, about two weeks later, I need to start the car, move the shifter between gears, and then back into park. After 2 - 3 times repeating the procedure, the warning message usually clears. The vehicle has been taken in for service. A new shifter has been ordered. The part is on back order.

We have had numerous issues with the cars brakes automatically locking up when something triggers the collision safety break. Specifically when crossing rail road tracks after a train has past. As a result the car stops completely and automatically while on railroad tracks and won't allow you to move. You have to put the car in park, wait (on railraod tracks) and then attempt to move but it may activate it again so you have to do it again. Meanwhile you are on tracks, with cars behind you honking and screaming. This has happened numerous times, reported it to our dealer, service and gmc corporate where nothing was done. They said they would put in a "black box" like device but never did. It is a major safety concern for my family and one that gmc is not addressing adaquately.

On november 8th, 2018 took vehicle into cappellino gmc buick, for oil change, tire rotation and inspection even tho inspection was not due until december.. Was told tires on these vehicles were waring unusually fast.. Notices were posted all over the dealers facility, told we could buy new ones for slightly less than new price because they were pro rated.. This 2017 acadia was leased new, less than one year ago.. We believe we should not have to pay for faulty product.. At that point called dealer we had purchased from and questioned what was going on.. We were told "if it passed inspection, tires should be good for another year." on 11/25/18, while pulling into driveway, the left rear drivers side tire blew out and was flat within a few seconds.. We then called dealer back again and was told to call roadside assistance then bring in asap tp dealer to get new tires. These tires are not safe. On 11/27/18 went into dealer with spare that we were told not to go over 40 miles on. They said they would split price of 4 new tires.. We said ok. They then tried to put 4 new faulty tires on vehicle. We refused to purchase more of the bad tires they then gave us the option of buying a different tire that had to be ordered and sent us off with the spare still on car.. We were told it will take at least 3 to 5 days to get the other tires.. We have used 20 of the miles just getting back and forth from dealer. We do not feel we should be responsible for faulty equipment on leased vehicle. These tires are not safe.. There are children in this car on a daily basis. This weekend we were to be at a hockey tourn. For one of the children, rooms have been booked and he is the teams' goalie. We have no way to get there now. We were not offered a loaner or any kind of help. Had this happened on a highway of any kind there is no telling what may have happened. We hope you will check into this asap

When you put the shifter into the park position and you try to turn off the vehicle with the start/stop button an on dash error code of 'shift to park' appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. It beeps incessantly, the battery remains on and the doors do not want to lock. Gmc has been made aware of the issue by hundreds of 2017 acadia owners however their engineers have not found a solution. This defect is forcing me to turn the engine on and off multiple times, trying putting the car in reverse and then shifting back in drive, wiggling the shifter, opening the rear passenger doors and repeating any and all of these processes until it eventually turns off the shift to park message and allows the vehicle to shut down (or if you can confuse the electrical panel and have another message pop up to override it, such as the one that says 'check rear passenger seat". I do not know if my car is ever truly in gear or not. I'm afraid that it might cause a dangerous situation where my vehicle rolls thinking it is not in park or the battery dies unexpectedly or the vehicle is stolen because it will not shut off or the doors will not lock. I bought this vehicle brand new and this started occurring at around 15,000 miles and is a highly reported problem that necessitates a recall fix for safety.

I purchased a new 2017 gmc acadia on december 14th 2017. On october 11th 2018, my acadia was rendered completely disabled by a what has been described by the dealership as a " dead battery" I was almost locked in the vehicle because the entire electrical system failed and the electronic locks would not operate. There was no previous indication, notification or warning by the vehicle and monitoring service or of an impending battery failure obviously, a 10 month old battery in a new car should not be completely drained after only 10 months of ownership ( leading me to believe there may be more at play than just a bad battery). Had this happened anywhere else besides my driveway, it would have been a major issue. The vehicle was then towed to the nearest authorized gmc repair facility. The dealership ran diagnostic tests of the electrical system and found nothing wrong, but this still leaves me with doubts about the reliability of the vehicle and integrity of the electrical system.

When the vehicle is parked after driving and the placed in park, the vehicle fails to recognize that is in "park". This causes the interior accessories to remain running as though the vehicle is running even when the engine is off. This happens when the vehicle is stationary. From review of information, this is a know manufacturing defect from gm. When gm was contacted to have repaired in the vehicle we were informed that they cannot warranty their vehicles forever and it would not be repaired. This seems to be an inappropriate response for an issue that is not a warranty item but has been published as a manufacturing defect.

This issue has happened 3 times now and is becoming a safety concern for my family and I and for others on the road. I purchased the car brand new in may 2017 and the issue occured for the first time on october 02, 2017. Second time was february 15, 2018 and the third time happened around early april 2018. While driving at a slow speed (entering a parking lot, in the middle of an intersection when I was about to make a left turn on a green light, and while driving in a parking lot after getting gas) the car made a grinding/clunking sound and was brought to a very abrupt stop. I tried to press the gas but the car would not move. I changed the gear from drive to park and then drive again and would still not move. I turned the car off and then back on and still nothing. I ended up figuring it out by pressing the parking break button 1-2 times and was then able to proceed to drive. It seems as though something may have triggered the parking brake but while I was in drive and while the vehicle was moving. I was almost rear ended when this happened in the intersection and also during the time I was unable to move in the intersection, my light had changed to yellow and then red and oncoming traffic was honking because they could not go on their green light due to me being stopped in the intersection. It was very scary and dangerous as it almost caused an accident 2 out of the 3 times it has happened. I told service dept at the dealership about it twice. They have "looked into it" one time but since they were not able to replicate the issue (obviously), there is nothing they can do. I am concerned about my families safety if this continues to happen.

I went to a local dealer and complained about a vibration/rumble while driving. It happened mostly around 1200-1700 rpm. The service manager heard of the problem. There was a manufacturers bulletin outlining the problem and suggesting a fuel management software upgrade. This was done. The bulletin also applied to cadillac xt5, which is on a shared platform with my 2107 gmc acadia denali awd. There are now several new rpm ranges when the vibration/rumble occurs in addition to the old 1200-1700. Not only has the old problem re-appeared but there are certain conditions about 1500 rpm when I am starting out from a stop for about 50 feet where the problem seems to almost stall out and then with a big clank (like down shifting or transmission is slipping and then suddenly engages) and takes off. I cannot help but think there is going to be a mechanical breakdown of something due to the sudden engagement and clank or even stalling out in traffic, if this problem is not fixed. I contacted the dealer once again but have not heard back yet.

The adaptive cruise control (acc) in my 2017 acadia denali will shut off and even cause the vehicle to break for no reason. This has happened numerous times, even with no other vehicle on the road or obstacles in the road. When it happens the acc will shut off, you will hear two distinct chimes and you will see a message saying, 'adaptive cruise control disengaged'. After this happens you will not be able to reengage the acc and if you try the vehicle will display a message that says 'temporarily unavailable.' I have had it to the dealership numerous times and they have stated they don't know why it would happen, and cannot do anything unless they can duplicate it. It happens a lot but the dealership and gmc say there is no problem. The first time this happened it almost caused my wife to wreck, since the acc shut off and applied brakes with no other car on the road, badly startling her, and she thought she had hit something. I even have a video of the acc showing 'temporarily unavailable' after one occasion it shut off and slowed the vehicle. In this instance there were no car in front of me or on either side, but there was one behind me who I am sure was not happy when the vehicle in front of him braked for no reason. A gmc representative told me I can have all the video I want, but it 'doesn't matter and won't change anything'. The dealership did do a complete diagnostic on one occasion and found evidence that the acc had shut off, but the code did not say why it shut off. This has happened at different speeds range from 55 to 75 mph. We have had it happen three times in a 30 minute period and drove for a month without it happening. This causes an unsafe driving experience and should be fixed or the vehicle replaced. I have found other people online who have experienced this, but there are not enough of us to warrant gmc doing anything.

As much as I love the vehicle as a whole, it unfortunately has the worst headlights I have experienced in any vehicle that I have ever driven. As someone who has perfect vision, I often find myself squinting to see the road ahead of me and various signs. It has gotten to the point where I have resorted to driving with my high beams on, just so I can see where I'm going in city streets, highway driving, and making turns. I've never had this issue with any other vehicle that I have driven and the unfortunate thing is that my father has nearly the same identical vehicle as me and is equally dissatisfied with the headlights. I would consider these as dangerous as anything to driver, pedestrian, and property related safety. I would strongly urge that if gm does not step up and correct this dangerous obstacle to my life, then I would strongly urge an investigation and an immediate recall of this vehicle by this organization.

Two month old 2017 gmc acadia denali fwd. Horn is nearly impossible to operate under any conditions.

I have taken the car back to the dealer and they said they adjusted the horn, but there was no improvement. We checked 3 other acadias on the lot, and they all had this problem.

The horn is extremely difficult to activate. A person must use extreme weight and pressure to get the horn to work. Dealership told me that I am not the first person to complain about the issue but as of yet there is no repair that they have to fix the problem. This occurs no matter whether the vehicle is moving or parked. This has happened every since the vehicle was new. The problem occurs every time I try to activate the horn.

The 2017 gmc acadia horn takes an unreasonable amount of force to engage. This has been noted by several users. My spouse had a semi truck come into her lane a day ago and could not get horn to sound to warn other driver. Gmc dealership investigated and said its just the way the assembly works in this model. I believe this represents a safety issue as it makes the horn unusable when you need it quickly and without taking your eyes off the road. Gm is saying to bad.

My 2017 gmc acadis 6 cylinder awd has excessive vibrations that occur at 1400-1600 rpm and at various speeds. It seems like the transmission refuses to shift and it lasts for up to a quarter mile. Vibration is most pronounced at speeds of 55-60 mph the dealer diagnosis says it is functioning normal. The struts were replace at1390 miles and motor mounts adjusted, problem remains, auto brought to dealer for recall as per bulletin 17109 but it still vibrates excessively. The lead mechanic at the dealership said the auto adjusts to the driver and said the vibrations will stop at about 2500 miles. The car now has 2900 miles and it still feels like the transmission is going to fail. The vibration is uncomfortable and although the dealership said the car is safe it does not feel so. It seems impossible for a vehicle to be functioning properly with this continual erratic vibrations.

The steering has locked briefly 3 times while driving on the freeway within the last few weeks. The first time I was changing lanes on I-8 going about 45 mph. The next time I was taking a freeway exit ramp from I-805 to the I-8 decelerating and had no control as I turned the wheel to maneuver through the curve. This past saturday, 4/8, I was exiting I-805 at sorrento valley road and the steering locked for over 2 seconds. I originally thought this was a suspension issue. However, I finally received service records from hoehn gmc in carlsbad on 4/7 that stated there was an issue with the vehicle before I took delivery. The service record states '40 dtc p16e5 sensor comm circuit 3 hign voltage' and a part was replaced. However, I picked up the vehicle on 3/2 and the service invoice has a date of 3/22. I have not been back to the dealer since 3/2. I had to leave the vehicle at the dealer on 2/28 when I signed the lease agreement because the dealership told me the transmission was still locked. When I picked up my vehicle on 3/2, I noticed the vehicle had 34 additional miles since my initial inspection on 2/28. After several unanswered emails and phone calls to jerry brummet over the last month, he finally sent me the service records to show the reason for the additional mileage. This surprised me because I was never notified of an issue when I picked up the vehicle, nor did I receive any service records. I do not feel safe driving this vehicle and would have taken it in for service sooner had the dealership notified and provided the service records indicating there were factory defects prior to my receiving it. I plan to take the vehicle to another dealership for service in the meantime. Ultimately, I am concerned this is a repeat safety problem that may lead to an accident or other bodily injury.

The passenger wiper blade does not cover sufficient area of the windshield to permit the passenger to see the 'right' portion of the road. The unwiped area accumulates dirt and adds to the visual obstruction of falling rain. An unbelievable visual distortion of the road results. I am 70 and am appalled at the lack of wiper coverage in a critical portion of the windshield for the passenger. Most passengers assist the driver in the safe operation of the vehicle by calling attention to impending problems. Their contribution is limited in this vehicle due to the poor wiper coverage of the passenger side. The portion of the car above the bottom of the windshield was moved in on the sides of the car by design change. The normal swath of the passenger wiper for a full width car doesl not work with this redesign. The passenger wiper pivot point should be closer to the front of the passenger and wipe to the right edge of the windshield. Help !!! This wiper situation is really awful, unnecessary, and fatiguing to the passenger. The a, b, and c sections of the windshield were selected for the specifications when we had full windshields going to the right and left sides of car. Now that the edges of the windshield has been moved in, the specification coverage for the passenger is not sufficient. Thanks for listening and hopefully, you can do something .... We hate driving this car in the rain.

The sales & service department said there is nothing they can do but I could look into after market headlights. Contacted gm customer service (case # 8-2826579557), their design team reviewed my concern and they have no planned changes to improve their headlights. If these lights pass any federal lighting requirements, the testing must have been done in a lab and not out in the real world.

This is similar to what feeling one might get if you moved from 2nd - neutral - 3rd gear. I started experiencing this issue from approx. 5k miles. This would be risky when you are trying to merge into a yield or change lanes and this shift occurs, you momentarily feel loss of control.

Description
Adaptive-cruise-control (acc)/forward collision braking(avoidance) system applied very strong brakes(twice) in certain scenario when using acc, increasing the chances of vehicle behind rear-ending. While acc is enabled, say your vehicle comes to fullstop as vehicle in front has come to a full stop(say at traffic signal) and acc applies full brakes. Traffic ahead starts moving again, but since vehicle won't move on its own driver is required to press accelerator to get it moving again or acc to resume its operation (this is by design). In such scenario if driver ends up pushing accelerator a bit harder(I. E. More than just tapping it), acc applies very strong brakes stopping vehicle right there. By this time vehicle behind you has started moving already and might rear-end due to abrupt stop. I guess acc thinks distance between you and vehicle ahead is very less and thinks its going to collide and hence applies strong brakes. But this is a bad design/programming since it expects driver to push acc. Pedal for acc to resume operations, but if driver does it bit more than what acc likes, there is a chance of accident. Gm should perform more tests with its acc around such scenarios and fine-tune their acc software. *tr

    My 2017 Acadia has the shift to park, electrical issues, and cooling unit issue. I have spent alot of money to find the issue. Got different answers from different shops this is insane

  • Mujeddid M

    I have owned my 2017 GMC Acadia for about five months. The day I drove it off the lot I had to bring it back because all of the dash lights started blinking on and off like crazy. The car started acting as if it would stall. I took it right back to the dealer. They took it and looked at it and told me that they needed to reset the electrical system and that everything should be fine. Several weeks later the same thing started happening again. I was also experiencing the shift to park issue, where after placing the car in park nothing would turn off and I would still be prompted to put it in park. Next, the check engine light came on and stayed on. I eventually took it back to the dealer to be looked at under my warranty. They found that 1. the front active grille shutter needed to be replaced; 2. shifter needed to be replaced; 3. that the trac control switch needed to be replace, but this was not replaced because the inspector for the warranty company said he saw evidenced that something had been wasted on the console, thus suggesting that alleged spillage was the result of the trac control problem. I told them that the issue with the trac control switch, which the repair man indicated was also the cause triggering the electrical issues with the dash lights, was happening the day I drove the car off the lot. I am still pressing the warranty company to cover this repair. 4. They also found a leak in the oil pan. All total, the repairs came to over $3,000, under the warranty, but I am still dealing with all of my lights in the dash (stability trac control switch) going crazy. I was completely unaware of all the problems this car was having. Now, that I know I would like to give it back, because it seems like the repairs are merely temporary fixes that will no doubt surface again. Please advise, and thank you.

    I’ve had nothing but problems with the Electrical system on my 2017 GMC Acadia Denali. We have fought the “Shift to Park” issue for the last two years. A couple of presses of the shifter button fixes the issue but it’s annoying. I have another problem that I have to get serviced so I’m going to have they try and fix this issue finally.

    I’ve had numerous times when the vehicle says that “Remote not detected in Vehicle” but it was clearly in the vehicle. Restarting the car several times seems to eventually clear it but it’s so crazy.

    A few times I’ve been locked out of my Acadia where it won’t respond to the remote at all. It just sits there in a completely hung state. Eventually after 30 or so minutes it starts responding again. Thankfully this hasn’t happened when we were out and it was 115 degrees out.

    Recently my battery went bad and when I had the Battery replaced everything seemed fine. That was until I realized the HVAC system wasn’t responding. Looking Online I’m not the only one who has had this issue after replacing the battery. Back to the Service center.

    I have never seen so many software bugs in my life.

    My 2017 Acadia Denali- I also have the “Shift to Park” light coming on when in park, also “Steering assist reduced, Drive with caution”, “Device battery Low”, when I had already changed the battery in the fab.

    I have had the same issues with my 2017 Acadia not responding to being in park and the horn being incredibly difficult to use. However, I had an issue at a red light where I was holding the brake and my car continued to creep slowly forward. I placed the car in park to try and stop the rolling but the car continued to roll forward until I tapped the car in front of me. It hadn’t happened before this or any of the remaining stops afterwards, but I am scared to death to get back in it. Next time it may not be a slow creep that I can’t stop.

    My ’17 Acadia was in the shop for a month while I waited on a new shifter, which was on a suspiciously long back-order, to replace the faulty one, which causes the “Shift to Park” message we all hate. At stop signs or stop lights, it hesitates and then lunges forward when I start to accelerate. When I asked the dealership to look at it, “it couldn’t be replicated”. I hope they can replicated my odd engine sound and jerky, sputtering acceleration when they have it again next week. My AWD is less than wonderful. I spin my (new) tires when trying to climb my steep-ish driveway, but our Ford Escape doesn’t have an issue making it up the road. I can’t wait to get rid of this car! Nothing but issues.

Closing and or shutting everything off & putting it in park BEFORE I release the seatbelt has allowed me to get out of my car on the first park & shutoff 6 times in a row now. My little experiment may help you…try it???? PLEASE let me know if it works for you.

    Had shift to park
    problem on 17 GMC Acadia fixed it. Replaced all wheels for peeling now since fixed to park running rough at stop signs and when apply gas doesn’t go then jerks forward. In park runs rough too not a good car don’t buy it!

    My car will be in park but the computer screen says I need to shift to park. I called the dealership and they stated my car just over 32,000 miles is out of warranty and I need to pay for it out of pocket. My Warranty was out on 08/01/2019. I have a 2017 GMC Acadia that I leased in 2016.

    Acadia Denali V-6 FWD. 30,000 miles. Have had the shift to park several times. Thought it was my mistake. Trans. seems to stumble on 2-3 shift randomly. Horn pushes way too hard. Dealer said they all do that and GM doesn’t know how to fix it. Denali Alum. wheels clear coat peeling off, supposed to be replaced by GM but no word yet.

    My 2017 GMC Acadia steering gets stiff intermittently while on motion and particularly while negotiating bends or corners. The steering glitches i. e. hard to turn in the middle of turning. It has now happened several times.

  • Kathy

    So far have really liked my Acadia……….got into my 2017 Acadia this morning, warning lights: service all wheel drive system and service Stabilitrak. Took to dealer they are trying to figure out. I have noticed before the parking issue. Put in park and get warning to shift into park. Another note, when on an incline the transmission takes a minute to go into gear.
    Afraid I have a lemon. Have owned the vehicle since Dec. 2018.

    I have a 2017 Acadia Denali, I’ve had the shift to park issue, which the dealership did fix, no further problems with that, then the AC wouldn’t come on with the remote start feature, now the AC is blowing hot air, it’s going to the shop today and then I’m trading it off on a new Ford Edge, should never have traded my Edge in on this, it’s a beautiful car, but 3 problems in 2 yrs makes me worry about when the warranty is up in another year what will happen then, on my dime.

  • Sasha

    I have a similar problem as the other complaints in regards to my horn. Also my radio is temperamental and the touch screen does not always work. I have brought my vehicle into the dealership a few times to try to get the car rectified.

  • Charris

    I too just also start experiencing the “shift to park” error with my 2017 GMC Acadia. I have a call in to the dealer for service but I am almost to my 36,000 mile mark. Since this is a known issue, I hope they dont make me pay to correct the issue.

  • Michelle

    I have a 2018 Acadia and have recently started dealing with the shift to park issue. The warning alarm stays on If you don’t play around with the gears to get it to realize the car is already in park so that the warning will go away. GM needs to fix this problem! But I know I will never buy another GM vehicle. They can count on that!

  • Jen

    My 17 Acadia had the shifter replaced and now when it auto stops at sign it wont turn back on and runs rough. Had the cylenoid replaced but still doesnt want to restart when auto stop.

    Reply to Mr Finkelstine 20 February 2019 comment. Today makes the 3rd time my car has COMPLETELY shut off while driving. This is so extremely dangerous! 2017 GMC Acadia

    And it vibrates terribly. Dealership says everything is ok.

  • Marko

    2018 GMC Acadia took to the dealer just inside the 36k warranty and had head rest on farthest aft seat replaced due to mechanical failure. I mentioned to the dealer if they knew about a shift to park problem as it happened to me once and they said they were unaware of the problem. Of coarse the 2017 model has the same problem and GM is putting their head in the sand and refusing to do anything to correct the problem. I can only hope we the taxpayers don’t have to bail out GM again and keep this totally worthless corporation afloat, I will never purchase a GM (Government Motors) vehicle again!

  • Jade

    I have a ’17 acadia and its a piece of crap. I got it with 10 miles and within 3 months the AC/Heat went out and has gone out a total of 3x, then the parking break, keyless entry, the dash display changes on it, the radio display has been changed twice and still has issues. I have taken it to the GM dealership 9x in less then 2 years and Im constantly getting the run around from GM and the dealership. I WILL NEVER BUY A GM PRODUCT AGAIN IN MY LIFE!! GM needs to pull their heads out their butts and call my car a freaking lemon. Everyday i drive my car with my kids and worried something else is going to go wrong.

  • Chris M

    Just sent my 2017 GMC Acadia to the shop today for the shift to park issue. Hopefully they know how to fix it!

  • EDWARD B

    WHEN THE VEHICLE IS IN PARK AND I TRY TO TURN IT OFF WITH THE START/STOP BUTTON AN ON DASH ERROR CODE OF “SHIFT TO PARK” APPEARS EVEN THOUGH THE VEHICLE IS CLEARLY IN PARK. I AM NOT ABLE TO TURN THE VEHICLE OFF. THIS CURRENTLY IS FORCING ME RESTART THE ENGINE, PUT MY CAR IN REVERSE, SHIFT BACK IN DRIVE, TRY RE PARKING AND TURNING OFF AGAIN REPEATING THE PROCESS UNTIL IT EVENTUALLY TURNS OFF. I’M AFRAID THAT IT MIGHT CAUSE A DANGEROUS SITUATION. BTW…. I TOOK THE VEHICLE IN FOR SERVICE ON 3/7/19 BUT WAS NOT ABLE TO SIMULATE THIS CONDITION AT THE DEALERSHIP. WITH THIS BEING THE CASE, THE DEALERSHIP SAID THEY COULD NOT FIX WHAT THEY CANNOT SEE. i SHOWED THEM ARTICLES WHERE THIS IS AN ISSUE ACROSS THE U.S. WITH THIS VEHICLE.
    WHAT I WANT: I WANT GM TO PUT OUT A RECALL NOTICE.

  • Eric F

    My 2017 GMC Acadia completely shut off while driving 70 on the highway. Thank god it turned back on within seconds. Service depends told me they have never heard that happening and that its impossible for that to happen. I have had nothing but problems with this car.

  • Brandy

    My 2018 Acadia has multiple issues. The main problem is when the sensor in the shifter starts to go out because this is the second time that it’s gone out. New steering control uses power the gauges start to go up and down and all phone telling me that I need to get my power steering check my parking brake check that I’m losing power steering stability control traction control. On top of all the happening while I am driving when i park or kill the car it doesn’t go off the electrical system stays on saying that the car is not in park wont start or shift. And the radio freezes up I cant turn it off down change the channel sometimes longer than 5minutes. I have taken it to multiple places an no one knew what was wrong.
