Dear general motors customer assistance center, I am writing to formally file a complaint and request assistance regarding a serious mechanical failure with my 2018 GMC Acadia slt. I purchased this vehicle when it had approximately 7,000 miles on it after it was transported from florida. Since owning the vehicle, I have properly maintained it and had it serviced through suttle motors dealership in newport news, virginia. Recently, while driving on the highway to have tires installed, the vehicle suddenly stalled while I was in traffic. This caused a very dangerous situation, as traffic behind me was forced to abruptly slow down and I was nearly rear-ended due to the sudden loss of power. Because the vehicle was no longer drivable, I had it towed to suttle motors for inspection. After examining the vehicle, the service department informed me of the following issue: “the transmission solenoid valve is stuck and it has burnt the transmission fluid. The vehicle will require a full transmission replacement. The estimated cost is $7,769 with a 3-year/100,000-mile warranty. ” I was extremely shocked and disappointed to receive this news. My vehicle currently has only 67,000 miles, and I have taken care to maintain it properly through the dealership. Experiencing a complete transmission failure at such relatively low mileage is very concerning, especially considering the dangerous situation it created on the highway. Given the circumstances, I am requesting that general motors review this matter and advise whether any goodwill assistance, repair support, or coverage options may be available to help resolve this issue. I would greatly appreciate your prompt attention to this matter. I can provide service records and documentation from suttle motors if needed. Thank you for your time and consideration. I look forward to your response.

My wife and child drove the car to the grocery store and parked the car l. When she returned to leave , the car would not start and flashed a warning with key fob not detected and some kind of security light warning. The instrument cluster told her to place the key in left console cup holder to crank the vehicle . This did not work either . I drove the second key fob to her to determine if it was a key fob issue and the 2 nd key did not work as well. Called dealership and service requested the car being towed. Tow truck didn’t feel comfortable with the removing the vehicle as it was sitting due to space in the parking lot. They dispatched a small tow truck , but in the meantime I disconnected the battery cable and waited about 15 min. The car cranked and I immediately drove it to dealership. There was no code shown at the dealership and this was the first time they have had dealt with this issue. The mechanic drove the car the next day and the same situation happened again , except this time the key fob worked after several failed attempts . I feel that this is a safety issue because the car failed to operate and had no manual ability to operate without the electronic system functioning properly and this could have happened anyway and stranded my wife and child . A few months before in an unrelated incident , the power trunk malfunctioned and had to be reprogrammed . It would not operate except manually . Car is currently at dealership still being evaluated .

Dear sir/madam, for the 3rd time now, my transmission is being rebuilt. After purchasing it from the dealership and it was still under warranty GMC bakersfield rebuilt the transmission, then again in 2020 at 119,000 miles it broke down again and all automatic in bakersfield rebuilt it for $3500 and now here it is 2026 and only 60. 000 miles later again all automatic is having to rebuilt the transmission again and asking now for another $4950. I was excited to finally hear there was a recall, only to find it was only for 2014 GMC Acadia's. The transmission have failed again and yes it is available for inspection at all automation in bakersfield, CA on quantico. During the course of breaking down the my safety and the safety of my children was at risk. My vehicle was jumping, jerking the rpm's were all over the place and at one point in the course of driving on the freeway it felt like it lost power and nearly stopped. This has been an ongoing problem since the purchase of the vehicle. It has been inspected and diagnosed by all automatic. There were no warnings, messages or symptoms that were constant. It was sporadically slipping up until the time it gave out. I have spoke to several 2013 GMC Acadia owners who have the exact same problem along with the back light covers falling off and all the plastic coverings on the inside falling off.

My 2019 GMC Acadia suffered a "major trans fluid leak" specifically from the transmission accumulator feed pipe. Because of this leak, the transmission lost its necessary hydraulic pressure, leading to "internal damage". This is why I experienced harsh shifts and a complete "missing 3rd gear". This exact part and failure mode are the center of NHTSA recall 20v668. The recall warns that missing bolts on the accumulator can cause a fluid leak, progressing to a total loss of propulsion—which is exactly what has happened to my vehicle.

Infotainment system freezing, screen shaking, touch screen not working, disconnecting from android auto, unable to connect to phone.

When I put the shifter to park, it still dings and tells me "shift to park" and I struggle to make it go away and to be able to make it stop and be able to lock the car. It happens every time I drive it. Thank you.

My car suddenly out of the blue started overheating. By the time I could get stopped safely and turn the car off the engine fan kept running to try to cool it down. I’ve never had any issues with my car. It only has 47,000 miles on it. I now have to have it towed to a mechanic shop to get diagnosed, but I’m hearing that it’s probably a thermostat and that the GMC Acadia’s are famous for that being a problem. I’m not sure why GMC would not do a recall on this part! this is an extremely expensive fix.

In March of 2022 at around 79,000 miles, the temperature gauge was intermittently stuck on cold with the cooling fan constantly running and “steering assist reduced” displayed in the dic. The car was found to have a bad thermostat which was replaced at the dealership on 3/28/2022. About 2 months ago the car started doing the same exact thing again. I have an appointment at the same dealership on March 23. It is likely the same problem again and I have only driven about 50,000 miles since the last time it was fixed. The car is now out of warranty. This is apparently a common recurrent with these model cars. There is in fact a service bulletin released about this very issue. GMC should replace and repair this issue since it is clearly a flaw.

When trying to put car in park a "shift to park" notice appears on dashboard not allowing the car to be turned off. It takes multiple attemps be able to get the car into park and turn off. This has been an ongoing problem for several years and reported to the dealer. To date the dealer tells me there is nothing wrong with the car. Battery has been changed multiple times.

On or about I experienced the check engine light on the above vehicle. After checking, the issue has something to do with the low level in the coolant system. I took the vehicle to a maguire Chevrolet dealership in grand island new york. They charged me $200. 00 +tax for diagnosis. They found the radiator hose was leaking and it isn't covered by the warranty or extended warranty. I took the GMC to another shop for repair. They were told by 3 dealerships the part is on back order and they do not know when it will be in. Just to be sure, I called the GMC dealership in rome new york where the vfw purchased the vehicle. I was told they were put of stock but there wasn't an issue. That was on 12/24/2025. The salesman said he would call me on Friday to verify the status of the hose needed. As of 12/29/2025 at 13:00hrs there hasn't been a call back. My feeling is there must be an issue with the hose in question. The should be a recall and gm should repair the leaking part.

Pulled into a parking space, put the car into park and tried to shut the car off. The warning system said I needed to shift to park. I was in park but could not shut the car off because the car thought I wasnt in park. Took 15 minutes of shifting from park to all gears and shaking the gear shifter before it finally let me shut the vehicle off. This is now the second time this has happened and ive had to have the same thing repaired. They are replacing the whole shifter assembly. Error reads shift to park. This is happening every few years now and at almost 1000 dollars to repair and only lasting a year or so, this is ridiculous.

The upper radiator hose, which is part of the vehicle’s engine cooling system, failed prematurely. The component is available for inspection upon request, and documentation of the repair and replacement can also be provided. Failure of the upper radiator hose caused coolant loss, creating a risk of engine overheating and sudden vehicle disablement. This posed/poses a safety risk, particularly if the failure had occurred at highway speeds or in traffic, where an unexpected breakdown could endanger the driver and surrounding vehicles. The issue was confirmed by an authorized GMC dealership, which diagnosed the failed upper radiator hose and performed the replacement. This issue has also been reported by multiple owners of the same model year, indicating a recurring problem. The vehicle and failed component were inspected by an authorized GMC dealership. No inspection by police or insurance representatives was required, as this was a mechanical failure and not the result of an accident. Prior to the failure, symptoms included coolant loss and cooling system concerns, which ultimately required dealership diagnosis. Any warning indicators appeared shortly before the issue was identified, with little to no advance warning before the component required replacement.

2018 Acadia denali with less than 50,000 miles on the vehicle. Had to replace the coolant temperature sensor and thermostat. Less than 30 days later. The check engine light came on and the code was coolant temperature sensor and thermostat. Code p0128$07e8.

Shift to park issue - this is a know issue/recall for the 2019 GMC Acadia yet it when I enter my VIN number the recall doesn't show up as a problem. Yet it took me 10 tries yesterday to try and turn my car off because each time I went to turn it off, I got the message to shift it to park. This has been occurring weekly since I purchased the used car in August 2025.

There are 2 issues im experiencing. The first is the vehicle won't allow me to shut down the engine because it doesnt recognize that its been shifted into "park". Ive already paid close to 800. 00 to. Have this repaired because my model year is not covered in the recall. Today, it started doing it again. The safety issue is that either I, my wife, or my teenage daughter (depending on who is with the vehicle). Can be left stranded, unless we pop the hood and disconnect the battery. The second issue is that the tire pressure monitor is no longer working. It is sending warnings that our tire pressure is low. When its not. The safety issue is needing to pull to the side of the road to check the tire pressure and also not knowing when the vehicle may actually have a low tire.

I accidentally ran out of gas and my car died directly underneath a railroad crossing arm. I had been stopped to allow an amtrak train to go by and my car died when I started to move forward after it passed. Thankfully I wasn't on the tracks, but I was close to them. I immediately got out of my car and the woman behind me said she would help push me out of the way of the crossing arm. I went to put my car in neutral, something I do weekly when I go through the car wash, but my dash kept saying "conditions not correct for shift". I tried repeatedly and it would not allow me to put the car in neutral because I couldn't fully turn it on. I did a quick search online and found there was no information on how to get it into neutral if the car is dead. My battery was still working and my car was in accessory while I was trying to change gears. I had to call 911 and they had to reach out to bnsf to alert incoming trains. It was an ordeal. I spotted a tree removal company across the street and they had a can of gas for me to use. I was able to partially fill my tank and then drive across the tracks before a train came. Afterwards I called the dealer and we discovered together that there is no backup safety feature that allows a disabled car to be put into neutral. The dealer was just as surprised as me. This seems like an obvious safety issue if a car is to break down on train tracks, the middle of the freeway, or in an intersection. I don't understand why it is allowed and why dealerships and the public are seemingly unaware of it.

Our onstar module has stopped working since last November after a software update and now issues are starting to cascade causing many other electrical issues to the point that I expect the car to leave my wife and 15 month old daughter stranded. Ours and many other vehicles are having this issue and when any question is asked to gm no response is given or we’re just told to keep waiting.

After I put my car in park my daughter and I were still in the vehicle for a few minutes getting our things with the engine still running. I got out to get something from the back seat, my daughter got out the passenger door and made it to the driver side as I was closing the back passenger door. I was about to get back on the car to get the rest of my things and turn the ignition off but before I could my car was rolling backwards out of the driveway into the street. I was able to jump in the vehicle and put my foot on the brake and the put the gear into park. There’s no way possible I didn’t put it in park with me getting out already and my daughter couldn’t have accidentally shift the gear because she couldn’t have been able to get out, close the door and make it to the driver side before it started rolling away. Once I got the car stopped, I noticed the driver seat was now all the way to the steering wheel and completely to the floor with the headrest also tilting inwards and now the electrical for the seat will not work. There is a recall for this issue but my VIN# is not included. I cannot even drive my car now because the seat is so far up and inclined. What if the seat moves up more while I’m driving and it has me pinned between the steering wheel and the seat. I don’t feel safe driving it, having my daughter as a passenger and it’s really not safe to be on the road. I’m still paying on this car and now I won’t even be able to drive to work. So I’ll probably lose my job. This car has multiple issues and I think is an electrical problem. It’s also a known major defect on this model but still not a recall for my VIN #! none of my interior sound works. Speakers, blinkers, alerts, back up camera. The auto start won’t start, I have to press the key fob multiple times to lock and unlock. This car is extremely unsafe to drive and I strongly feel my cars VIN# should be listed under the recall. Its going to really affect my daily life and means of income. Lemon!.

Shift to park caused by a faulty micro switch. Woukd take up to 30 min to get car in park, leading to engine shutdown failures and possibly battery drain I did replace battery before I knew this was causing this. Messages did appear saying this was an issue ,must shift to park but no indication of how to do it. I got this repaired at barkley GMC Dec 29:30.

When in park the car is alerting to “shift to park”.

Coolant temperature gauge stops working and shows cold temperature reading. The radiator fan runs for about 2 minutes as if the engine is overheating. I think it's a temperature sensor issue or thermostat issue or both.

Seeing the intermittent shift to park messages when the vehicle has been shifted into park and the ignition is turned to the off position. Shifter wire harness jumper & transmission controls a malfunctioning shifter raises fears of potential rollaway accidents, even if such cases remain rare. For anyone who has to park on a slope, this fear can cause serious worry. Yes, there is a service bulletin (19-na-206) no, this is 1 of the only problems I have had with this. The other issues I have had is the clear coating on the rims are peeling.

I was driving on a two-lane road when unexpectedly my front moonroof spontaneously shattered sending glass down on top of me, the console area, and the passenger and rear seating areas of my 2025 GMC Acadia. It happened without warning and no external factors. It was a pleasant sunny November day. The moonroof was not open at the time. Fortunately no one else was in the vehicle with me at the time and no other cars were nearby since the two-lane is not a heavy traffic area. This put my safety at risk and could have put others at risk had others been in the vehicle or nearby since I was startled and had the natural reaction of crouching over and down in an attempt to protect myself therefore taking my eyes off the road and not paying enough attention to driving the vehicle. Glass could have fallen and hurt other passengers. The remaining moonroof glass crackled and I then looked up in shock wondering what happened and then feared glass fall into my eyes and immediately looked down away from the moonroof. I had just left my residence before the incident and was less than two miles from home. I found the next available place to turn around and drive back to my home and exit the vehicle. I then called the dealership I bought the vehicle from in January 2025, new. I also called gm customer service to seek assistance. The vehicle has 7125 miles. There were no warning signs. The incident happened today and no one has inspected the vehicle and its damage. A customer service case was opened with gm. I sent pictures to the dealer service manager who said he attached the pictures to my gm case online.

No specific incident. High pitch rattling in ceiling. Does not seem to be coming from the sunroof but the middle light fixture.

Vehicle is in park, and the shft sensor does not recognize the shifter is in park. Won't let you turn off rhe car.

Vehicle has an ongoing water leak, has been to the dealer twice so far. Both times said it was fixed.

When I put the car in park, I get an error message that says shift to park and it takes putting in park numerous times to get it to clear so I can trun the car off and lock it. I know there have been some models that have been recalled due to this problem, however mine is not included in that recall. I would like to know why it is not included and if there is any help available to correct this issue.

I continue to get a message "steering assist is reduced drive with care " this appears to be a very common issue with my vehicle model. It is very expensive to fix. I am just outside of warranty so it is not covered. Online indicates this is so common. It is the vehicle thermostat and sensor prematurely going bad.

Shift to park error message when in park.

The put in park shows after engine is turned off, have to restart and shift out of park and back to park. This could take several times to accomplish.

GMC customer care representative & local GMC service department supervisor unable to help. 2017 Acadia shift to park message. It’s difficult to turn the car off. The vehicle refuses to acknowledge the park position. Potential rollaway hazard. You may inspect. Took it to GMC service & confirmed it is a prevalent issue: transmission control 13534320 = gearshift assembly & jumper harness 84733196. This problem has been recurring for several years and I have problem solved how to shut the car off. GMC customer care rep said it’s an issue with all 2017 Acadias and tried to help. The system deemed it complicated case & escalated it to a supervisor. She read a “customer care” script. After talking, she admitted that realistically GMC would not help. Yesterday, she advised me to file a complaint with NHTSA. I read that 2 other states ohio & tennessee won class action lawsuits because of the hazardous shift to park issue. If GMC issued recalls for 2017 Acadia shift to park then my 2017 GMC Acadia should have been included. I have been waiting for the recall for several years. GMC admits the problem is prevalent in 2017 GMC Acadias. Would you please issue a recall associated with this issue and link it to my VIN. Thank you.
