Electrical System
The electrical system in any high-end SUV should have every amenity the driver could imagine. Even when it is fully equipped, all these technologies must work properly for maximum comfort. What Acadia owners find is that multiple aspects of the electrical system seem to fail and become a disappointment.
Just read this NHTSA review. “I purchased the wireless charger. I received the GM document stating what version of phone I needed for the charger to work. I purchased a phone and the charger does not work. The dealer researched the phone and there are only specific models manufactured in the same year that work for the charger. I have tested with five different model phones and only one worked. This option is a waste of money and not advertised appropriately nor do the GM brochures or website provide adequate information to notify the consumer of the issue.”
When looking through the long list of manufacturer communications, we see that electrical troubles seem to run rampant. While some of them deal strictly with comfort, there are some that put drivers in danger. For example, Service Bulletin #PIC6123E discusses how the adaptive cruise control and lane-keep assist might not work after the information center sits in the sunlight or gets hot. The company wants owners to know that this is natural and to simply allow the unit to cool down before using it again. Hopefully, no one bought this vehicle that lives in Florida or Arizona. Otherwise, they might spend a lot of time waiting instead of driving.
Engine – Shift To Park Error
Everyone expects the engine on a high-end SUV to work properly. It’s needed to get the kids to school and head to work every day. When the engine doesn’t operate correctly, nothing seems to go well.
Look at this NHTSA review talking specifically about trouble with the engine. “Shift to Park error 90% of the time when I attempt to shut the vehicle off. It is in park and it’s not recognized as being in Park. It can take me anywhere from 30 seconds to 5 minutes to jiggle it the right way to get it to register. Problem is until it does register in Park I can’t secure the vehicle. And it dings nonstop draining the battery. I understand GM is aware of the issue and doesn’t have a fix. It needs a new transmission in my opinion. I’m stuck in a lease paying for a car that isn’t safe for me. It just started 6 days ago and has already occurred more than 2 dozen occasions.”
While this complaint is prevalent among all forums, there are other engine issues happening. Even GM acknowledges multiple problems including Service Bulletin #PIP5486D, which discusses a rattling, knocking or ticking noise. It might also lead to misfiring. The cause is a spongy stationary hydraulic lash adjuster or a damaged switching roller finger follower. They also state that the noises can be heard constantly or under extreme loads. It’s possible that these unusual sounds might keep the owners occupied as they spend time trying to get their SUV into Park.
Powertrain
Hand in hand with the engine is the powertrain. These two systems are the heart of all the mechanics happening under the hood. Sadly, the Acadia can’t seem to get this right either.
Just look at this Edmunds review from an owner. “My transmission has been having issues when shifting from 2nd to 3rd. I took it to the dealership immediately after noticing. They say it’s not throwing codes so they have no idea what is wrong with it. The vehicle has been to the dealership six times so far and it will be going back again tomorrow. They can’t seem to fix the problem. They say they don’t know what is wrong with it. The last time they had it they said they replaced the transmission module and found a bad motor mount. They said the transmission fluid was dark so they realized they did have a problem, just as I have been saying for a month now. Well I got the car back yesterday and noticed it is doing the same exact thing but a little worse now. A lot worse. I called GMC and opened up a case with them a couple of weeks ago when the dealership was unable to fix my car. Well GMC will NOT return my calls.”
GMC went beyond just discussing drivetrain problems and went ahead with a recall. While it’s not directly related to the transmission, NHTSA Campaign Number 17V516000 talks about the right front intermediate driveshaft fracturing and separating while owners are driving. When this happens, the SUV loses propulsion and might lead to a crash. If it happens while parked, the vehicle might roll away. After hearing about all the problems this vehicle has, it’s possible that some owners wish it would just roll away.
Service Brakes
While discussing rolling away SUVs, it makes sense to move onto the service brakes. This system must operate correctly to keep the vehicle where it belongs.
Check out this NHTSA statement which illustrates how defective the brakes are on the Acadia. “The contact rented a 2018 GMC Acadia. While the contact’s friend was driving 40 mph, the engine revved and the vehicle accelerated on its own. The brakes failed to stop the vehicle. As a result, the vehicle drove through a partition and crashed into a brick wall. The air bags deployed. All four occupants in the vehicle were injured and received medical attention. The contact suffered chest pain, another occupant sustained a cut on the head and the other two occupants suffered fractures. A police report was filed. The dealer and manufacturer were not contacted. The cause of the failure was not determined.”
This situation has gone ignored by the automaker. Instead, they use their communication to discuss things trivial, such as Service Bulletin #17NA217. It talks about applying grease to the shims of the front brake pads to reduce squealing noise. If only they could come up with a solution to get the vehicle to stop, owners would be much happier. It doesn’t help to have quiet brakes if they don’t work.
Electronic Stability Control – Stabilitrak System
Modern vehicles use sophisticated stability control systems to keep the ride comfortable. When this malfunctions, it creates numerous safety concerns that must be dealt with.
One NHTSA user discusses this problem in detail. “The Service Stabiltrak notification keeps coming on and shutting off on its own while in motion on a street and it has also happened while on the highway. It has occurred at different speeds and several times with different people driving. The dealership can’t figure out why and it doesn’t show it even came on at all. When in motion on a street going 46 mph, the car tried to auto correct pulling me out of my lane by itself. It was a straight street with no curves where this occurred.”
Unfortunately, the company hasn’t addressed any problems with their Stabilitrak System. They decided it was time to ignore the complaints and pretend that nothing is wrong. Clearly, they don’t want to draw attention to one more problem in their premium SUV. Otherwise, customers might just opt for the lower cost Chevrolet Traverse and keep some additional money in their pockets.

| Description | Erroneous error code on heads up that car not in park. Appears to be in park, error code can be reset by activation/deactivation of trigger switch on shift lever. Provides unclear message if car is or is not in park, vagueness makes me question vehicle park status overall. Issue was very intermittent in 2022, frequency of erroneous error code increasing now happens 1 out of 5 times when shifting to park. |

| Description | 2018 acadia will display “shift to park†warning along with an audible warning when the vehicle is shut off. This happens even though the prndl display is in the “park†position each time. If I try to exit the vehicle, the audible warning continues (apparently indefinitely). This began at an odometer of about 59,200. Initially, the situation could be corrected by restarting the car and shifting in and out of park or depressing the shift knob several times. Within a couple of hundred miles, it became consistent and eventually could not be corrected as described above. Unfortunately, this is not covered under warranty. I began driving for a few months without the shift knob, simply depressing the plunger on the shift rod coming up from the transmission. Doing this, the warning rarely occurs and, if it does, it's easily corrected with one or two presses of the plunger. Some modifications of the shift knob have allowed the knob to be used with results similar to driving without the knob. I hope there will be a software update (deployed over onstar) to use the prndl information and eliminate this failed system. |

| Description | For months after putting car in park it displays a "shift to park" message. It won't let you fully shut down vehicle. Some times I can start it again, back up a little, put it back in park for it to shut off. Not one time though. You have to do it repeatedly. Maybe 6 or 7 times before it works. Most times I just finally have to walk away from the vehicle. Problem being it won't let me lock my car - which the police in our area keep warning us to do to prevent the vehicle thefts. It also continues to 'bing', running down the battery, which could leave me stranded somewhere. I looked this up on line assuming it would be a recall because it is a 'known defect' and there are thousands of complaints on line of people having the same issues and dealer won't take care of. There are lawsuits. This should be a recall. |

| Description | Shift to park issue. Vehicle appears to be in park but message appears. You have to continuously wiggle shifter and shut car off and off until it registers it is in park. I have no way of knowing if vehicle is truly in park or not. For safety reasons I cannot park in an incline due to concerns the vehicle will roll backwards. Several tbs bulletins have been issued by gmc on this known issue and they deny any responsibility of fixing the situation with a recall. The nhtsa needs to step in and investigate and require gmc to remedy this dangerous defect |

| Description | I purchased vehicle in 2018 and by 2019 it started showing a message that said error shift need to park but I was parked and gear in parking mode . I reported to dealer but said they couldn't help me since my warranty was over due to my job I drive alot so I was over the mileage. So they itbwouldnt be covered since then it goes off and on same message and now I can't get off car until it goes off because I'm afraid to let go of brake if the parking gear don't work. I reported to dealer in time to get assistance but they just brushed it off blamed me for the mileage maybe causing it but I see here I'm not the only one complaining about message "shift". |

This happens intermittently and but it is a bit of a pain when it does. I have to either jiggle the shifter or start the car up again and shift into park again. I just called the gmc dealer where I purchase the vehicle new, mark porter in pomeroy, oh, and they said there is a bulletin from gmc on it and the fix is to replace the shifter harness which would cost me around 0. And they said if that doesn't fix the problem the next step would be to replace the shifter which would cost me another 0. In looking online it seems to be happening to a lot of 2018 gmc acadia's and am wondering why there is no recall on it. |

| Description | In 2019 my gmc acadia had the “shift to park†issue in which my vehicle would not shut off and I would have to repeatedly start and shift the gear shift before it would shut off. The problem was “fixed†at the dealership in june 2019. In may 2022, the “shift to park†issue started again. At the dealership now and was informed that since the vehicle is out of warranty, I would be responsible for repairs this time. This is a safety issue that gmc is well aware and should not happen to begin with let alone after repairs. In no way am I going to be held responsible for repairs that obviously were done with either defective parts or parts that were limited to only 3 years without my knowledge. If I knew I would have to do the same repair in 3 years and I would be responsible for it, I would have argued for better parts to begin with. Gmc needs to know that this is a real problem that needs to be dealt with immediately. |

| Description | After putting the vehicle in park, I get a "shift to park" error. The car does not recognize it is in park, so it will not shut off completely. It takes several attempts of restarting the car and putting back into park before it will recognize it is actually in "park". This has been happening for several weeks. |

| Description | The contact owns a 2018 gmc acadia. The contact stated that upon depression of the brake pedal, the brake pedal was depressed to the floorboard without warning. The contact had taken the vehicle to a dealer where she was informed that the brake pads and all four rotors needed to be replaced. The contact then called brad deery motors (112 n. 2nd st, maquoketa, ia 52060) and was informed to take the vehicle in to be diagnosed. The contact was then informed that only one of the rotors needed to be replaced. The vehicle was repaired however, the failure persisted. The contact also stated that upon attempting to park the vehicle, the shift to park warning message would illuminate on the instrument panel. The contact had to repeatedly shift the vehicle in and out of the park before the vehicle would recognize the shifter in the park position. The manufacturer had been notified of the failures but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 46,000. |

| Description | I'm getting the "shift to park" message when my vehicle is already in the park position. This issue first started happening in 2019 and I took it to my local gmc service center to be looked at since it was still under warranty. It started happening again about 2 weeks ago. My extended warranty and powertrain has expired, so I'm concerned that the same dealership will charge me for this repair when I take it this week. If this is a known issue with this vehicle, as evidenced by the scores of complaints related to this issue, why isn't there a recall on this vehicle? |

These problems are clearly manufacture related and in no way normal wear and tare. I should not have to compensate these issues when I paid near 40,000 for it |

| Description | When I put my car in park and turn off it will randomly say "shift to park" it started doing this in aug or sept 2019 the car was under warranty and I brought it to a dealer to "fix". Fast forward april 2021 it started to say shift to park again and car is no longer under warranty. Called different dealers even the one I brought the car to fix problem (that was a joke), they know its a problem and saying since that part got fixed in 2019 with a bad part and now there is a a newer fix that should work better, but I will have to pay for diagnostic test and part again. Again they know it is a problem with these cars and it needs to be recalled. I have to turn the car off and on reshift, push the shifter harder, etc to get the message to go away so I can turn my car off. |

We had a prior issue where the emergency brake was on, auto backed in a driveway with slight incline, and when we tried to disengage it was simply stuck, we called to tow the care; once driver arrived we went through the release one more time and it finally released.

| Description | This vehicle has always since we bought it gave us tremendous problems while driving during a snowy day. Brakes typically do not work, at times even going through a red light and thankfully not been in an accident. Recently, the stability control system and the antilock braking system stopped working while under a snow storm. Unfortunately, we took it to the nearest delearship to get it fixed and we were told that the problem was due to the snow, but after the snow everything was good. Unfortunately, people do not have the money to pay for a vehicle and have it parked during the winter, that is what is happening to us. Because nor the dealership or gmc has done anything to help. This has been reported since december 2018, the vehicle has 34500 miles on it and is relatively new now, but we should not have these issues. It is of our knowledge that many people who bought this vehicle have the same issues. It would be good if they accept these vehicles have issues and correct them prior to promoting and selling to customers. Since they did not correct these issues prior to some individuals to purchase the vehicle, they should work on a solution via a re-call to avoid any injuries to families of their vehicle's owners. |

My car has roughly 42ooo miles only and was stationary when this occurred. I called my local gmc dealer in new jersey and they said it was not under recall, it is a known electrical short and my vehicle is not under warranty. They wanted 400. 00+ to fix the problem or issue. Upon an internet search I learned that this is a common problem with this model.

When the car is turned off, there is an alert that comes up on the display saying to put the vehicle in park. It isn't every time the engine is turned off, but it can sometimes take up to four or five tries to get the car to register that it is in park. I shift to park, turn the car off, get the alert. So I turn the car back on, shift to a different gear, and than shift pack to park and turn the car off. And repeat this until I stop getting the alert. When it is put in park, the car will shift slightly if I get this error. I've started using my emergency break whenever I get out of the car to make sure that it won't roll. |

This is a safety issue and very frustrating. My warranty expires on 12/14/2020 and because there are so many complaints on the gm authority website this should be a recall so myself and others are not stuck with paying for something that is no longer under warranty. This happens when a vehicle is put into park and then this shift to park error message comes up. Sometimes you cannot even shut the vehicle off. Both repairs involved replacing the shifter assembly. This is a gm problem and should they should issue a recall. |

It's a safety hazard. I looked up the issue online and found out that most of this car owners experience the same problem and there's multiple lawsuits against gmc for this issue. This car is driven by my wife most of the time and she has my kids with her in the car. It's a life threatening issue! I took the car last month to the dealership and they refused to fix it for free because the car went out of warranty by only 2k miles, and I couldn't take the car to the dealership when this issue started because of the covid. By the time we could visit the dealership we already drove over 5k miles and that puts the car outside the warranty limit. |

| Description | When the vehicle needs to be shifted to "park", the car notifies you on screen "shift to park" and then becomes stuck and you have to keep wiggling, trying to get it to actually park until the notice goes away. It happens at random and has been going on for the last two weeks. There seems to be no recall, yet the 2017 2018 models are all having this same issue and there is no recall yet. This is a huge safety issue and we are now being responsible for the charges to have it being fixed. This should not be my responsibility as it is hugely aware to all the dealerships and there are court cases being filed because of this. |

Upon investigation, I found that this is a very common problem with 2017-2018 gmc acadias (there is even a class action law suit pending). Some owners even report their vehicles rolling when in this condition. As of this date (5/19/2020) gm has not recognized this as a design problem and has not issued a recall. This is obviously a design issue since it happens within and out of the 3yr/36,000 mile warranty. If it happens at 36,500 miles the vehicle owner is out of luck! This is also, obviously, a safety issue. Thanks for your time and help. *tr |

| Description | I have received the 'shift to park' error message on the dash when the car is already in park. One time with the car off, the error message on, the car started to roll despite it being in park. I had to restart the car, shift the shifter down then back to park back down and back to park before the car would recognize the shifter was in park. Each time this happened when I was in a parking spot and in my garage. |

| Description | When the vehicle is warm, the transmission appears to slip when shifting from 2nd to 3rd gear. The engine will rev between 500 to 1000 rpm while shifting. During this time (half to full second) the vehicle is not accelerating and does not respond to throttle inputs. The vehicle has been taken into dealerships 4 times for this complaint. At 35000 miles (3rd dealer visit), gm replaced the valve assembly. The problem reoccurred and gm is only offering to replace the same part, or extend the warranty on the transmission, but not both. No one at the dealership or gm technical assistance center has any idea what is actually wrong and is not taking any steps to find the cause of the issue. The service manager has admitted that there is a problem, but gm denied him any help in resolving the issue. They have said that this is not a safety issue, but I do not feel comfortable driving a car that may become unresponsive to accelerator pedal input for a full second. Note that this issue is still covered by the powertrain warranty at this time. |

| Description | On december 5th 2019, I arrived home from work to take my son to his dr. Apt. I pulled into my driveway around 10:30am. I left the car on so my son wouldn't have to go into a cold car, being he way sick. I ran into my house where my mother was watching both my sons. I said to my mom, let me use the restroom quickly before I get his coat on. I was no more than 2 mins. As I stepped out the bathroom, I hear my husband screaming from up stairs the car is on fire! He comes running down there stairs as fast as he can, almost injuring himself because he didn't see me yet and thought I was in the car! He then sees me and grabs the fire extinguisher. He runs outside to try and extinguish the fire.. As I called the franklin square fire department and 911. But in under the 5 mins the car was engulfed in flames! We had to then evacuate the house because the garage is an attached garage and the car was in the driveway of the garage. My poor kids were frightened for their life as we rushed them out the house as their mommys car was up in flames.. They were crying their eyes out in fear. The fire caught onto the tree on the front lawn as well as destroying the garage and driveway. I cried extensively thinking of the what ifs... What if I put my son and I directly into the car, without using the restroom that day. What if this had occurred when I was driving on the parkway with my whole family in the vehicle. This vehicle was a death trap that almost took my life and my family. We found that their had been a recall on the gmc acadia for the 2017-2018 editions. I having a 2018, where was my notification of a recall? Where was my letter.. Email.. Call from gm? I have numerous friends the recommend the gmc acadia as a great family car. They are all now scared to death because of what happened to me. Non feel safe using their vehicle now. |

| Description | My 2018 gmc acadia slt-1 has been having acceleration issues like shuddering and or feels like a full loss of power , with no check engine light. I've taken it into the dealership twice for this problem . I've only taken it in this 2nd time because it got worse and scared me that it would die on the highway. It also has had to have the battery charged 3 times in a couple of weeks , yet the dealer says the battery checks good. At the least I believed since its under warranty they would change the battery in the case the computer is causing issues based on battery voltage. The alternator is working , but with only 29k miles none of this battery nor acceleration shudder and stumble like its going to die should be acceptable. |

| Description | The vehicle will not always go into park. In order to get it into park you have to repeatedly shift out of park and back into park until it will go into park. If it is not in park the vehicle will not lock and will not power down. Since it will not go into park if the vehicle was on a hill and it did not go into park then it would have the chance to roll down the hill. I have not attempted to see if it will roll down the hill nor am I going to try but seeing how it shows on the instrument cluster that the vehicle is in neutral I'm sure it will roll if given the chance. When shutting off the vehicle after you have put the vehicle in park on the gear selector a message comes up on the screen that says shift to park it has taken up to 20 tries of shifting the vehicle in and out of park until park will engage. As you can see in the picture all gauges are at their lowest point showing no power to the vehicle and the shift indicator is in the neutral position with the message on the display reading shift to park. |

| Description | I put my 2018 acadia in park in my garage (a flat stationary spot) and I receive a message that states 'put vehicle in park', which it already is in park and as a result the engine won't shut off. I have had this occur several times over the past month, but most recently occurred on october 24, 2019. It is my understanding it is possibly a bad shifter assembly which not only will keep the vehicle from shutting off, it can also not hold the vehicle in park. I have researched this issue and I am disappointed to discover that gmc is aware of this issue occurring with the vehicles. This is a serious issue especially if it will fail to hold your vehicle in park. |

| Description | Vehicle engine was running when I came to a stop and shifted to park. I received an error indicating "action required - shift to park." I did not let off of the brake pedal because I was unsure if the vehicle had actually shifted into park. With the brake pedal applied, I attempted to shift to neutral and drive, then shift back to park, and received the same error. With my foot still on the brake, I turned the ignition off, but the electronics would not power off and the error continuously displayed on the dash. I started the engine and repeated this process multiple times with the brake pressed before changing gears again, shifting into park, then applying the electronic parking brake with the engine running. It was only then that I turned my engine off again, and the error finally no longer displayed. Since the error was no longer displaying, I could only hope that my vehicle was actually in park, but felt reassured that the electronic parking brake was engaged. Please investigate this safety concern that seems to be affecting many of these vehicles. |

| Description | After shifting my acadia into park and shutting it off, "shift to park" warning comes us sounding an alarm that won't go off unless I start the car and shift in and out of park several times. It gets harder to get the warning to go away each time I drive it. I have had to result to not driving it to avoid the battery draining or having to unhook the battery. The car only has 19000 miles so the dealer is willing to replace it but there are no parts available. Also, others have mentioned that the problem returns even after the repair. |

| Description | Shift to park notice. When attempting to turn off vehicle and shifted into park, vehicle will give a warning that vehicle is not in park. At this point I have no idea if the vehicle is in park or not. Not sure if I am just receiving a faulty notice or is the vehicle not in park and could roll causing injury! This is not a safe vehicle. Gmc unable to repair due to not having the part available. This may happen for two or three times. It has happened that I have had to turn my car off and back on up to seven times before it registered as in park. |

| Description | When pushing vehicle ignition button "start/stop" to turn vehicle "off" it will turn the engine off but keep the vehicle still "on" using the battery. If I open the door and shut it, the horn honks to alert that the vehicle is still "on" and not completely stopped. The only way to get the ignition button to acknowledge the vehicle is off is by jerking the gear shift until the green light goes to "off". It does not do it every time I turn the vehicle off, but it does it about every other time. I will take it to the dealership very soon for them to look at this also. |

| Description | When turning off the vehicle, a warning message comes on saying "shift to park" even though the vehicle is in park. The shifter reads park and so does the dash. Vehicle is unable to be completely turned off or locked with this message appearing. It requires turning vehicle on and off, moving shifter in and out of park, jiggling shifter buttons, etc. This can take one try or multiple tries. I just had this fixed by the dealership (replaced shift control) and was disappointed to find that this is a known issue, affecting many vehicles and it is still the responsibility of the vehicle owner to pay for the expense if the bumper to bumper warranty is expired. The shifter runs the power train! Why is this not under the power train warranty and why is this not a recall? Now, in researching, I'm seeing that many have had it happen again after the issue has been "fixed". Dealer tech notes tsb 19-na-206 in his report. |

Putting it into gear and back to park was not helping. The last time it took nearly 30 minutes before I could get the car to shut down completely as it kept staring shift to park. Car was not moving had only gone within city limits with max speeds of 45mph. |

| Description | When shutting the acadia off it prompts a message saying must be in park. It is in park but computer is not recognizing it. This forces you to leave car running. If you dont then your battery will go dead. When speaking to local dealership they are aware of issue but dont know anything to resolve it. Customers shouldn't have to pay for this since it's a safety issue. |

| Description | The vehicle would display a dashboard warning "shift to park." every time the vehicle was put into "park" the vehicle would not register that it was in park. This would prevent the vehicle from being turned off. A driver would think the vehicle was in park, and take their foot off the brake, but the vehicle would not register it was in park and would display a warning on the dash "shift to park." you would then have to shift back and forth, from park to reverse or drive and then back into park for the vehicle to finally register it was in park. This would occur while the vehicle was stationary and sitting anywhere you would park the car. |

| Description | 'shift to park' error message is showing when my vehicle is already in park and I'm trying to turn the vehicle off. I purchased this vehicle less than a month ago and it currently has 33k miles on it. I've had to turn the vehicle back on several times to get this error to go away. When the message flashes I've even experienced the vehicle rolling indicating it is in fact not in park although the shifter is in park position. This needs to be recalled immediately and I will also be consulting an attorney as this is a known issue with no clear fix (many people who have had the shifter replaced are having the same problems again) and the part that needs to be replaced is on backorder. People's vehicles literally cannot turn off resulting in batteries dying among the very obvious safety concerns. How is this legal? |

| Description | First of all, this issue is being reported by hundreds if not thousands of gmc acadia owners. I received the "shift to park" message months ago while it still was under the 36,000 mile warranty and then it went away until last week. I got a "shift to park" message when I turned the vehicle off even though the gear was in the shift position. This caused a number of secondary issues that are now compromising the safety of the vehicle. Once I am able to turn the vehicle back on after it drains or kills the electrical system, I am getting a number of issues. However, the ones that concern me the most are the rolls even though the vehicle is in park, loss of power steering, loss of awd, loss of stabilitrack, loss of abs, braking system error and power surges. These are the most concerning but I am also having issues with my dashboard, navigation, and vehicle instruments. I called the gmc dealer who had no problem telling me the gear shift box needed to be replaced, not covered under warranty and they had no idea when they can fix it because it was on a national back order. What really disturbs me is that there are lawsuits going on dealing with this particular issue and that literally it compromises the safety of the vehicle and neither gmc or the nhtsa have acted on this. I was driving today and realized how dangerous it was to operate a vehicle under these conditions. You can literally be driving and the vehicle have a power surge which makes you lose control caused by a malfunction in the gear shift box. I am assuming that no one will due anything until several people are either killed or seriously injured. This issues has been reported on models going back to 2017 and here we are in 2019 and still have the issue. Please help us, this issue is happening to thousands of drivers and it is not being addressed by the nhtsa or gmc. Please recall or stop selling |

I restarted the car, shifted out of park, back into park, tried to shut off again... Same thing.... 4x's!!! I went right over to the dealer where I bought my car and explained what was happening ( couldn't shut off there either). Service manager knew immediately what the problem was but says the part (gear shift) is on backorder and has no idea for how long!!! What??? Why isn't this a recall? I've read quite a few of this same complaint so I can't understand how this isn't a recall already especially if the gear shift required to fix the problem is on backorder, it's obviously a bigger issue then 1 or 2. So for now , I just have to wait and 'keep playing with the gear shifter until it goes off' as I was told until the part comes in! How crazy is this |

Took it chevy place in glenpool, ok. They couldn't find anything. 2* on 2 occassions, in motion, the car accelerated with a loud noise & as if it were getting power & not moving then jerks & speeds up about 15mph faster & I couldn't stop it. I kept slamming on my breaks, but the break would only go in so far. I was frightened with my 2 young boys in car screaming. It's like riding a horse & it takes off & you can't control it. 3* on about 8 or 9 occassions stationary I get out of my car & it makes a really loud annoying sound like a machine/robot powering down. My kids always say, it's going to blow up 4* the most annoying, for past month... Stationary, every single day & time I turn my ignition off. It has loud beeping sound & check rear seat flashing on screen then shift into park flashes. This occurs every single time I turn my car off. Sometimes I have to just let it go on all day because I can't get it stop. I turn car on & off shift back & forth & it still will not go off. Sometimes it does after long periods of time. I don't have time to struggle with getting a car into park every single time I turn my ignition off. I have to beat it forward hard with my hand to the point my wrist is bruised. Now I have to use my foot to kick gear shifter into park. I'm afraid t's going to roll out & or down and hit something, someone or even one of my children. Which would not be good. I've seen several of same complaints. This really needs to be investigated & recalled asap. My elderly mother had to call my brother to another part of town to beat the gear shift into park. This car was brand new & I shouldn't have any of the above mentioned issues. It's frustrating thinking gmc was top of the line & it's not. |

| Description | I financed this vehicle in may 2018 through a gmc dealership. It is january 2019 I started getting alerts once I put my car in park and turned the motor off. The warning alerts stated on the dashboard "action required -shift to park-" even though it is is park. The alert is loud and will not go off. I have to start the car again and adjust the gear shift a few times by moving it to drive, neutral or reverse before the vehicle recognizes that it is is park and the alert leaves the screen and the sound goes off. Sometimes it takes a few moments of moving the gear shift before I am able to leave the vehicle. This is highly inconvenient especially when you are in a hurry to leave the vehicle. I am extremely frustrated because this is a brand new vehicle. I contacted the dealer and they immediately asked me was the car still under 36,000 miles. Thankfully it is. I entered my vin number in this database and no recalls have came up for my model oddly. But for a different model of the gma acadia 2018 there is 2 recalls. Ironically, the same complaint has been reported. |

If I move the seat and then hit the memory button so it will go to the set position the seat doesn't move at all. I have had rental cars more than my acadia the past 2months while the dealership trys to get these issues fixed. I love the car but am getting mad with all these issues. |

| Description | I purchased the wireless charger. I received the gm document stating what version of phone I needed for the charger to work. I purchased a phone and the charger does not work. The dealer researched the phone and there are only specific models manufactured in the same year that work for the charger. I have tested with 5 different model phones and only one worked. This option is a waste of money and not advertised appropriately nor does the gm brochures or website provide adequate information to notify the consumer of the issue. |

| Description | Front seats feel loose and like they shift. When they shift and move a popping noise is heard. The shifting and popping noise happens in and out of corners, going over driveway/parking lot aprons. The sensation is unpleasant and irritating. Have spoken to dealer and auto body shop. Associates claim similar problem existing with yukon's. Does gmc have a seating problem or recurring defect? |

| Description | When you put the shifter in park it does not recognize & cabin alarm starts to beep. The vehicle will also leave its headlights on overnight & drain your battery. Took to dealer and they couldn't do anything about it. It's been 2 weeks and no letter of resolution from manufacturer as the dealer said. |

Hi – does the car have to be under the original warranty to qualify as a lemon? Or does the law include extended warranty? Thanks.
