Owners of the GMC brand expect a luxury feel with durable quality. That’s what the company used to stand for when it made reliable vehicles. The 2019 GMC Terrain might be a compact SUV that appeals to the masses, but it has a faulty engine, shoddy powertrain and defective vehicle speed control. All of these are vital components that drivers need; without them, the Terrain doesn’t offer much.

Problems with the Engine
The engine is the heart of the entire vehicle. It gives the SUV the “get up and go” needed to get from Point A to Point B. When the engine fails, there’s no hope of getting anywhere.
Just read this one review on the NHTSA website about the engine problems. “I have a 2019 GMC Terrain with 2,500 miles. I was driving it and the car flashed low fuel, check transmission and check engine warning and shut down while I was at highway speed. I was fortunately ok, however it stranded me at a spot with merging traffic, no shoulder and no power to get the vehicle out of there. The vehicle was able to start up shortly, then I had to deal with getting going again in this precarious spot.”
The service bulletins regarding engine troubles are overwhelming. The company discusses oil leaks that are happening, stalling issues and rattles that shouldn’t exist. It seems this company has more engine trouble than it cares to admit. If drivers wanted a 2019 Chevrolet Equinox, they would have paid a lot less to get it.
Here are some actual complaints logged with the NHTSA about the 2019 GMC Terrain Engine Problems
ON MAY 25, 2019 THE CHECK ENGINE LIGHT CAME ON, I WAS LOSING POWER TO THE ENGINE. THAT SAME NIGHT CUSTOMER SERVICE TOWED MY VEHICLE TO SUNRISE CHEVROLET BUICK GMC, 1800 COVINGTON PIKE MEMPHIS, TENNESSEE 38128, A NEARBY GMC DEALERSHIP AND SET UP A RENTAL CAR IN THE AREA FOR ME TO DRIVE. BECAUSE IT WAS THE HOLIDAY, ENTERPRISE WAS CLOSED, AND I HAD NO VEHICLE TO DRIVE FOR TWO DAYS. THIS WAS AN INCONVENIENCE TO ME AND MY FAMILY, I HAD TO ALTER MY TRIP PLANS THAT WERE MADE BACK IN FEBRUARY 2019. ON MAY 27, 2019 I WAS TOLD BY [XXX] THE TECHNICIAN AT SUNRISE CHEVROLET THAT AIR BOX TUBE WAS LOOSE AND NOT PROPERLY INSTALLED AND COULD HAVE BEEN DONE DURING MY SERVICE I HAD DONE APRIL 23RD. I WAS ASSURED EVERYTHING WAS OKAY AND I WAS GOOD TO GO. ON MAY 31, WHILE TRAVELING BACK HOME THE CHECK ENGINE LIGHT CAME ON AGAIN. SAME MESSAGE ON THE DASH AND IT WAS RAINING AT 3AM. I WAS CLOSE TO HOME AND WAS ABLE TO MAKE IT TO THE DEALERSHIP THAT I PURCHASED IT FROM.MY VEHICLE HAS BEEN IN SERVICE SINCE MAY 31, 2019 AND I AM JUST FINDING OUT THAT I HAVE A PART THAT IS ON NATIONAL BACK ORDER. I AM NOT SATISFIED WITH MY EXPERIENCE AN I AM REACHING OUT TO YOU TO RESOLVE THIS MATTER.
JULY 10, 2019 AT HIGHWAY SPEED UPON ACCELERATION TURBO BODY TUBE BLEW OFF SUDDENLY AND ENGINE REDUCED TO HALF POWER / CHECK ENGINE LIGHT COMES ON. THIS HAPPENED AFTER ONLY 1000 MILES ON NEW CAR. AFTER A REPAIR BY DEALERSHIP JULY 11,2019 SAME PROBLEM OCCURRED JULY 12, 2019 WHILE ON HIGHWAY. WAS 4,000.
Problems with the Transmission
Another vital component is the transmission, which is part of the powertrain. If this is built well, the car shifts appropriately and provides a comfortable ride. As can be expected, GMC didn’t seem to get this right either.
Just look at what this person wrote on the Edmunds website. “Purchased my 2019 Denali terrain on10/31018 and the entertainment system has not worked right since I got it. Been to the shop one time already, and still isn’t fixed. Also warning signs for “ service transmission “ on it has already started coming on, and it doesn’t even have 2500 miles on it. Breaks are scrubbing also.So disappointed in my Terrain. Cost too much for the quality of the vehicle.”
This owner has a lot of complaints, more than just the transmission. It seems the entire vehicle is malfunctioning at once. Again, the automaker has a slew of service bulletins related to the powertrain. We see reports of the charge air cooler pipe connection coming undone from the throttle body and issues that stop the vehicle from going faster than 25 mph. The only consumers that might be happy about that would be grandma and grandpa. They just need someone to give them a ride to the dealership when the car is ready for more repairs.

TL* THE CONTACT OWNS A 2019 GMC TERRAIN. THE CONTACT STATED THAT THE VEHICLE WOULD NOT SHIFT INTO GEAR FROM THE PARKED POSITION. THE VEHICLE WAS TOWED TO DEALER BUT THE FAILURE COULD NOT BE DUPLICATED. THE FAILURE RECURRED AGAIN TWO WEEKS AGO AND THE SERVICE TRANSMISSION AND TRANSMISSION UNABLE TO SHIFT INDICATORS ILLUMINATED ON THE INSTRUMENT PANEL. THE FOLLOWING DAY, THE INDICATORS ILLUMINATED AGAIN AND THE VEHICLE WAS TAKEN TO LEHMAN BUICK GMC (21200 NW 2ND AVE, MIAMI, FL 33169, (305) 356-7579).

JUST OVER 5200 MILES STARTED EXPERIENCING TRANSMISSION SLIPPAGE WHEN STOPPING OR STARTING. AROUND 5500 MILES STARTED HEARING LOUD CLICKING ROARING SOUND. WAS RETURNING HOME FROM VACATION ON A SATURDAY AFTERNOON AND KNEW ALL SERVICE AREAS OF ALL GM DEALERSHIPS WOULD BE CLOSED BUT HEADED TO A NEARBY CHEVROLET DEALERSHIP IN BOSSIER CITY, LA TO LEAVE CAR TO BE LOOKED AT ON MONDAY. NEVER MADE IT. CAR STALLED AND WOULD NOT GO INTO ANY GEAR. HAD IT TOWED TO DEALERSHIP. FOLLOWING TUESDAY RECEIVED TEXT MESSAGE FROM DEALERSHIP THAT THE PLANETARY GEAR AND SOME OTHER PARTS WENT OUT. PARTS ON ORDER BUT NOT AVAILABLE UNTIL FOLLOWING FRIDAY. SEARCHING INTERNET FOUND SEVERAL REPORTS OF 2017, 2018, 2019 GMC TERRAINS HAVING TRANSMISSION ISSUES. SEEMS GM HAS TRANSMISSION ISSUES WITH THE TERRAIN TRANSMISSION OVERHEATING, SLIPPING, AND FAILING.
Problems with the Vehicle Speed Control
Advanced technology makes modern cars safer and more enjoyable to drive. There are new systems installed every year, causing automakers to compete over who has more driver aids available. With vehicle speed control systems, crashes are being avoided – when it works properly.
The 2019 GMC Terrain isn’t one of these vehicles. This Edmunds user says, “Do NOT waste your time leasing/buying one of these cars. After watching my parents have several GMC’s, I decided to get one myself and it is the biggest regret. I had the car for THREE WEEKS when it had to go into the shop for the first time. It spent a month in the shop due to a broken torch tube and driveshaft. A month after that, my car had problems with the engine and it would reduce the engine power while I was driving down the road. It spent over 10 days in the shop for that issue. Since then, it’s continued to have problems with the navigation and the heating system. I have been calling GM multiple times trying to get them to get me out of my lease so I can get into something I can actually rely on and they are horrible at calling back. Do not buy this car unless you want it to spend 40 days in the shop before it’s 7 months old.”
Despite the overwhelming amount of complaints regarding the speed control, there are no service bulletins discussing the problems. With more than 170 communications about the smallest issues, it would make sense that GMC would address this somewhere, but they don’t. Instead, owners are left wondering why the engine continues to throttle back the power. As stated above, there is only a handful of people this SUV might be useful for. It’s like the turtle racing the hare, except it doesn’t keep going. Not only is it slow, but unreliable and fails at the most inopportune times.

| Description | Brakes failed on my car while driving and ran through 4 way stop. Took car to dealership and was told the vacuum pump seized up and sheared off. Asked the dealership what caused the problem and all they could say was normal wear and tear of the vehicle. Dealership called and said it was going to cost 0 dollars to fix the problem. I asked what that included and they said a new vacuum pump and to clean the motor out. Picked the car up on monday and by tuesday evening car would not run. Took it back to the dealership and am now told I need a new cam shaft which cost another 00 to fix. This is a serious safety concern as I had no warning or received no notification that the brakes had failed just went to stop and could not. How long is gmc going to let this issue go before being addressed. How many people have to die first before they recall them as the have already recalled the bigger models of gmc, chevrolet, cadillac and buick for the same reason? I don't know how people are suppose to afford to fix an almost brand new vehicle that they are still making payments on.. Something should be done asap... |

| Description | We were in the driveway thru lane at a fast food restaurant and all of a sudden the car shut off and the brakes got hard to push in. The car was able to be started at this time but the engine wasn't working well. We were able to make it home, slowly and carefully. We had the vehicle towed to a mechanic and this is what was told to us: possible increased brake pedal effort due to mechanical engine vacuum pump failure. We had it sent to david's auto service 219-861-0666. This could've been a very dangerous accident if we were driving on the expressway or on a regular street going the normal speed limit. Thankfully we were in a drive thru lane. |

| Description | After driving down around 40 miles, the brakes failed when pulling into a parking spot. There was no indication that the brakes were having issues. No sounds or vibrations were felt. I stopped at a stoplight before turning into the parking lot. Then when attempting to spot in a parking spot, the brakes were very difficult to press. Luckily there was not a vehicle or person in front of me. Had the vehicle taken to a dealer and was told it was the vacuum booster that failed. Upon researching, this has been an issue in past gmc models, but I was told there was no current recall for the vehicle. The vacuum booster was replaced for 0 and I drove the vehicle home. The vehicle showed no issues for the first day. On the second day, I went to pull into a parking spot at a park and the same issue with the brakes occurred. I nearly struck a child that was walking in front of the parking spot. Luckily I was able to slam the pedal to the floor and come to a stop. Took the vehicle to the mechanic and was told the same part had broke. That part has been fixed again and has been fine for 2 days so far. I'm scared that it will happen again and I will not be able to stop in time before I hurt someone else or my family. This needs to be addressed. And I believe I am owed compensation from the manufacturer. |

| Description | Our son and two daughters were driving on the highway at approximately 70mph when a message came up to say the engine was in "reduced engine power". Although nothing seemed to change. The instruction for such and error message is to "get vehicle to a dealership within the next day." so they slowed to 60mph and continued on their way. About 8-10 minutes later another message popped up that said "service brake assist", at which point they immediately tested the brakes and they worked. But 2-5 minutes later they tested the brakes again and the brakes had completely failed! Zero brakes on the highway! No matter how hard the driver pushed the brake pedal there was 0. 0% response. So luckily they were able to coast down to about 10 mph with hazard lights on. But at that point they lost everything. No power steering, no engine, and zero brakes. Thank the lord that they were able to have enough room to slow down and get over to a shoulder prior to the loss of power steering and that they had enough room to coast to a stop. Please help, as we were extraordinarily lucky that day that 3 of our children were able to walk away from such a catastrophic vehicle failure. I just do not want that to happen to anyone else. |

| Description | The car failed to shift into gear. Message displayed, "transmission unable to shift" ,"2 gears selected " or "service transmission". Issued started in june 2022 while in drive thru line, when shifting from park to move the car would not shift. Had to turn car off for about 10 minutes and car was able to shift and drive normal. Check engine light came on about a week later and had checked for code p07b5. A couple of days later, light went back off. About 3 days later getting ready to leave home and car would not shift into gear again but turn car off and back on a couple of times and car shifted and drove normal. On july 13 2022 was driving in traffic and message displayed, unable to shift and service transmission. When I changed lanes and released the gas petal, the car went into park, stopped, and set the parking brakes, but did not turn off, jerking me forward and throwing things around in the car. Cars behind me had to slam on brakes to keep from hitting me because there was no initial brake light. I put on the flashers and turned the car off. Parking brake was stuck so I pressed it about 5 times before it finally released. I restarted the car 3 times and it finally shifted and drove as normal. I called gm to inquiry about a recall and was told there were none. I called for a diagnostic test and schedule is in about 2 weeks. The car has not been inspected by anyone listed above?⸠|

I was driving through a school zone when the brakes went out, I noticed as I was not able to stop at an intersection. This could have led to multiple injuries, including children being in harms way. I had no warning this was coming and now look towards a hefty repair bill. Gmc has recalled vacuum pumps in other models but for some reason the terrain is not included. I wonder if there just haven't been enough deaths caused by faulty brake systems for them to cover this model too. |

| Description | I received a "service brake assist" message which came on then off. Took the car to a local mechanic who looked it over and said to see dealer as they saw nothing obvious. Internet search revealed that many people with terrain said this warning came on when battery was low. Made a service appt for nj dealer for 12/6/21. On 12/3/21, began a 1200 mile drive from florida to nj, after 2 hours, check engine light came on. Took the exit ramp from I 75 and at end of ramp, there was a total braking failure. I had to press very hard to eventually stop. Shut off car, attempted to restart but it would not. Towed to a mechanic who found fluid leakage and a repair bulletin on gm site involving vacuum seal camshaft. #pip5598a diagnostic tip. Internet search reveals many anecdotal instances of same problem. On monday, 12/6/21, I received an email from gmac saying that the on board diagnostics had shown a "low battery" concern. The catastrophic loss of braking seems to be connected to a low battery situation. This needs to be looked into by nhtsa. |

| Description | Transmission would rev up between 4th and 5th gear only in the on the first drive. After that it would shift normally . Went into dekalb gmc illinois and was told it was some pistons and other parts. They had it for a week or two because of other trans jobs ahead on mine. Got car back and it was working fine for a month or so and then it started to shift bad again between the same two gears only longer gap between shifts this time. Took it back to the dealer and the tech ordered more parts to repair the trans and said I would possibly get it back on october 19th by end of day. Is this going to be an ongoing problem? If so what is the law about 3 or more repairs for the same problem. This is the second repair so far. |

Not everyone has to spend once a week on a new belt buckle which should last a lifetime. This is beyond dangerous, since seat belts are mandatory and my wife being unable to use it can be a matter of life or death. This is her only means of transportation and we can't just park it and use another. I can't possibly be the only one. Thank you for taking the time to look into this matter. Please let me know if there is any further information regarding this matter. |

Found bulletin 19-na-181 which was very close to all symptoms and stated to check for chaffed wires near the ecm. Found no spots in the tape where it was rubbed through but lost comms when wires were shook. Unwrapped main engine harness loom and inspected wires, found nothing. Started tac case # 9-6385087421 and was told it probably is a chaffed comms wire somewhere and gave me multiple locations to check. Found no damaged wires in those locations and shaking main harness no longer would make it fault. Put it all together and drove it down the road and faulted immediately. Unwrapped main harness again snd sprayed with saltwater to help conductivity but still couldn't get it to fault while shaking the harness. Only way it will fault is when shifting into drive the drive train bumps just right to bend the right wire. Checked every wire I could find and can't find the problem wire. Not drivable. When this vehicle faults it will not shift past 1st gear and sometimes locks out reverse. Must be towed. Needs the main wiring harness to start, recommend customer to authorize fse to dealership cust declined. *yes, all the lights and messages were coming on over the dash. |

| Description | When I shift it from reverse to drive on a very slight incline, the engine will rev and not accelerate after I initially start moving forward. It actually almost comes to a stop before finally accelerating. It has now started doing it while driving and stalled in the highway on 2/13. I carried it last year for the same issue, but they told me they couldn't duplicate it. Today, they told me the same thing. They can't explain why it stalled in the middle of the road. Even though the check engine light came on and on-star told me to carry it to a dealer. The service tech guy also told me that my vehicle had 67,000 miles on it. It has less than 30,000 (not sure on the exact number since it is still at the dealership.) it is no longer safe to drive, but since they cannot duplicate it, they aren't even going to investigate it further. |

| Description | Bought the terrain in nov 22nd 2020 at covina chevrolet, california. On nov 25th wanted to restore the car stereo because the settings would not delete data saved and it wouldn't connect to my iphone via usb. So I decided to disconnect the posts from the battery terminals for 30 minutes. Connect back the posts to battery and check if that delete everything and it did but it still wouldn't connect to my iphone. That's when I noticed that srs and service esc message came on. The abs, airbags and stability lights were on, turn off the vehicle and turn it back on and didn't fix the issue. I made a repair schedule where I bought the vehicle and till this day dec 13th they haven't fixed the issue or their not even trying. Service advisor advise me that they are getting in touch with a field gm engineer that was a week ago. I'm thinking its just the computer that is frozen a malfunction abs module controller or a fuses or a relays because I drove the vehicle to the dealer and had no issue. I live in oxnard, california and its about 1hr 30min from the dealer. I'm still hoping that they can fix the issue because I really like this vehicle. Please help gm!! |

Shut my car off cause I had no clue what to do. Sat for a few minutes, collecting myself and turned it back on. All lights were gone, so I decided to continue the drive home. Took my car into the dealer the following day, found code p0300 stored in history. They did an update, and hoped that would solve my issue. Alas, it did not. This same issue has happened at least 6 times now. The 5th time, again, on a smooth highway, I completely broke down and had to be towed! It has now been sitting at the dealer for two weeks (since july 31st) while they try and diagnose the issue. |

| Description | Two incident warnings on my dashboard saying of my back hatch was open when it was not. Had it serviced because the dash warning would not shut off. Service said it was fixed then happened again. Twice this happened intermittently. Another incident when on navigation screen, when the navigator gave directions it changed to phone screen and went back to navigation screen when she stopped talking, like she was calling me to verbally give me directions! The most worrisome was as I was going 50 mph on city street, my gas peddle stopped engaging with the engine and I was loosing speed, as I pressed on the gas peddle harder the car was decreasing in speed as I watched the speedometer. During that incident all was working including brakes, radio and steering. I proceeded to drift into a driveway to stop the car for help, good thing I was not on the freeway could have gotten killed. The car is getting serviced now, I do not want it back, will trade in for different make/model is this considered a lemon and which laws/action do I take? I've only had the car only 7 months when this started to happen. |

| Description | The vehicle was purchased on june 22, 2019, with 19 miles on the odometer and had 1102 miles on it when the incident occurred. On 19 july, 2019 my wife and I were driving on interstate 95 near the rocky mount exit when I pulled into the passing lane to go around slower traffic (approximately 70 mph). Upon pressing the accelerator the engine rpm increased, but the vehicle's speed did not. Almost immediately the vehicle experienced a violent surge (to the extent that I thought I had been rear-ended) and the vehicle accelerated. At this point, we were startled, and continued until exiting nc hwy 13 with no further incident other than the cruise control becoming inoperative after the initial incident. Upon arriving at the outskirts of greenville, nc we encountered a red light and had to stop. Upon pressing the accelerator, the engine rpm once again increased and another violent surge was experienced. At that point, we entered a gas station and called onstar for roadside assistance. The car was subsequently towed to a local dealership (brown & wood gmc) where the on-duty mechanic duplicated the unsafe condition. Dealership stated that they did not know what was wrong because the vehicle was so new, and they could not contact corporate until monday (july 22). I returned to the dealership saturday (jul 20) to get a status and make arrangements for a loaner vehicle and was informed by the service advisor that the issue was with the vehicle was even worse than the day before - I did not inquire as to what that meant because it was pretty unsafe and scary to experience it the day before. I was notified yesterday by the dealership that the issue is a valve body, but that they did not know how long it would take to receive the part. |

This was my first brand new car and I was excited. I traded in a 2014 gmc terrain in the process, knowing I would be upside down on the loan. I had the first service done on april 23, 2019 at said dealership. At that visit I explained that I was hearing a noise on the passenger side vent even when the hvac was not running. I was told nothing was detected and my vehicle was fine on may 24, 2019, I drove my vehicle to memphis tennessee with my family for memorial day. On may 25, 2019 the check engine light came on, I was losing power to the engine. That same night customer service towed my vehicle to sunrise chevrolet buick gmc, 1800 covington pike memphis, tennessee 38128, a nearby gmc dealership and set up a rental car in the area for me to drive. Because it was the holiday, enterprise was closed, and I had no vehicle to drive for two days. This was an inconvenience to me and my family, I had to alter my trip plans that were made back in february 2019. On may 27, 2019 I was told by [xxx] the technician at sunrise chevrolet that air box tube was loose and not properly installed and could have been done during my service I had done april 23rd. I was assured everything was okay and I was good to go. On may 31, while traveling back home the check engine light came on again. Same message on the dash and it was raining at 3am. I was close to home and was able to make it to the dealership that I purchased it from. My vehicle has been in service since may 31, 2019 and I am just finding out that I have a part that is on national back order.

I began my drive into work this morning (3/4/19) and merged onto the freeway and seconds later heard a loud explosive sound, only to realize the first half of my panoramic moonroof was shattered (see inside photo). Shards of glass were falling into the vehicle but it had not collapsed completely at this point. I did not drive under anything that may have fallen, there were no objects in the road that came up to hit my vehicle, the glass just shattered out of nowhere. After calls with the dealership and roadside assistance, I decided to attempt to close the inside cover for the moonroof and drive to the dealership. I was able to do so successfully but as soon as I moved the vehicle, you could hear the glass collapse (see picture). |

My 2017 model opened to at least 76 inches which is more reasonable. I consider this a safety issue, as this is a flaw in the design of the vehicle. The model that has a power lift gate opens to around 76 inches.. A full 7 inches higher than the manual one.. The dealership never pointed out this problem to me seeing that I am 74 inches tall. |

| Description | When trying to start vehicle with push button ignition and brake pedal depressed, the vehicle failed to start. The dash lights would come on and error messages such as low battery came up on dash display. Vehicle was purchased on 11/17/18. Two separate occasions occurred where the car had to be jumped. One on 11/21/18 and 11/22/18. Unsure if an electrical wiring issue or battery issue? |

| Description | The shifter is dangerous. It allows you to inadvertently shift into neutral while driving. In a car with a normal shifter, the shifter needs to be pushed with significant force to move it into neutral and the resulting thunk will let you know it happened. In this car, since it is an electronic button that can be easily pressed, especially because it is in a location where it might get hit by an object like a purse. The driver may wind up without power and then not have an easy way to reingage drive. Also, there is no physical differentiation between drive and reverse, which can cause confusion in low speed driving interactions if a driver does not look at the buttons. Vehicles should have a software update to indicate when the vehicle goes into neutral above a certain speed as well as having the physical buttons replaced with something that offers a tactile difference between reverse and drive. |

| Description | Vehicle can be inadvertently by either a passenger or an object put into neutral. No alert or chime is made to alert the driver that the car is in neutral, only the gear selector on the dash or the light on the button indicates that it is in neutral. If something is covering the shifter, such as a bag or other item, it is possible that an acccident might occur becuase the bag or item may press the button, shift the vehicle into neutral cause the driver to be confused and not have power to maneuver the vehicle in an emergency situation. A chime should alert the driver that the vehicle has been put in neutral so it draws attention to that fact. In another scenario a small child that is old enough to sit in the passenger seat but not old enough to understand the controls might press the button, causing the driver to have an accident because they are not able to maneuver out of the way of an impending collision. I have verified this possibility by pressing the neutral button at various speeds and it is very possible for it to happen unintentionally. Other vehicles with similar systems have the buttons and or shifter in a place where inadvertent engagement of the button is unlikely. Other scenarios - people placing phones, bags etc during the course of driving, as on a highway may interfere with shifting in an emergency situation or may cause one by putting the vehicle in neutral. As in an hour in on a long drive, someone blocks the shifter because they aren't in need of it at the moment as they might be while parking or maneuvering in city traffic. |

All of these comments and review are occurring for my vehicle too and the dealership is literally telling me that they have heard this complaint.. even say it is COMMON yet they don’t have a solution or have not received a recall yet…. WELLL I didn’t sign up for a problem, I bought the vehicle because I truly believed a GMC over other brands would have value… meanwhile my vehicles depreciation at this stage of 15,000 miles/2019/4vmonths old purchased with 7 miles… especially considering the 38,000 I paid upon purchase after additional warranties** to protect myself…only to get it appraised at their dealership for 16,000… that alone told me the issues with the electrical screen cutting on and off prohibiting me to utilize apple car play, listen to music, etc. Jumping. Shutting off and not restarting with auto stop. purring and rattling engine, delayed acceleration, slow turtle compared to other competitors and priced way over the average competitor were more than likely true. when I shift its always extremely uncomfortable as the vehicle slams the breaks throwing you forward. The transmission or engine is defective regardless of their results.. it sounds like there is CLEARLY something not right. The vehicle will slow itself when I am trying to accelerate and I am pushing down on the gas petal.. it will almost rev and then slow to a put again and then RATTLE… I HAVE ALREADY HAD OIL LEAKS.. and its so disappointing to have quite frankly given myself more of a problem than what I traded out of and no one given me even a solution to a common problem and defect in their product?
HOW DOES THIS MAKE SENSE
WHY am I bearing the consequence of negative equity that I recently had paid off trade, YEARS to accomplish, and it was an achievement for me to get a new vehicle and this vehicle has done nothing but disappointment me, inconvience me, and put me in debt that I downright will not stop until I get back,
I respected this brand until their lack of attention to thousands of customers driving defective products and they have yet to create a solution that we can use to create reliability. A vehicle is the second largest purchase one makes… I didn’t spend that kind of money to own a problem GMC won’t acknowledge exists.. I expected quality. NOT TO MENTION… the warranty and rental policies require24 hours before they allow that coverage . every single time they do a diagnostic and tell me everything is perfectly fine and I leave with the same problems an hour or two later and I KNOW they obviously weren’t thorough.. problem occurring immediately upon leaving. I am just so discouraged with this.. they don’t believe this issues exist so now I know I’m not cray cray. Just give me my money back. Take your problem back and give me an opportunity to buy something that performs simple function but they do not respond to complaints…
DO NOT BUY THIS CAR
