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.

While driving the temperature gauge drops from normal to cold , the dash displays " steering assist reduced" and the fan is very loud . My mechanic said the thermostat and or sensor needs to be replaced . When he resets with the reader its good for about a week and temperature gauge is normal. After seven days it repeats I only have 40,000 miles on the vehicle and its a 1,400 dollar job. I believe this should be a recall because i have seen a lot of the same complaints in this forum and what about the people who have the same problem but don't complain ?

When I’m driving on the highway, I get a message on my dashboard saying steering assist reduced, drive with care. I have taken to the GMC dealership and they will not cover this repair even though it would be covered for 2021 GMC.

Gear shifter is not registering that the vehicle is in park. Because of this issue I have to sit in the vehicle for up to 15 mins trying to get it to register that it is in fact in park and can turn off. If I didn't take the time to do this, it would kill my battery. Unfortunately with the heat index, the vehicle gets hot very quickly and im now worried about getting hot stroke trying to get it to register it is park. This is a known issue with the vehicle that has an active recall for other vin numbers with the same issue.

For the last 6 months, I keep getting a "shift to Park" message on my dashboard indicating that my vehicle is not in park (in which it is). The problem is getting wors, so I called GMC on 5/14/26 to inquire and was informed that my VIN number WAS not include in the resent class action lawsuit for this issue. I then found out by searching myself on line for other complaints that GMC is very aware of this situation and yet refuses to fix the issue free of charge to customers. According to TSB 19-NA-206, t does list my year , make and model of vehicle affected by this faulty part. On 5.15.26, I called the dealership to inquire and was informed that my VIN was not covered under warranty (which I had already known), and that that service I would have to pay lots of money out of pocket for it. The service tech did look in the system and claims (without me even knowing that they had did that repair already....He lied I'm for sure). I informed him well if they did repair that part, and I'm still getting an error message about the same thing, clearly its faulty and the dealership should be responsible for fixing it. This was not the case as I was informed it would have to be out of my pocket. This mess is unfair! GMC is well aware of this faulty pat on vehicles, and to refuse to fix it free of charge is just down right hurtful! GMS is responsible for repairing this part on everyone's vehicle as it is a hazard to everyone and the community to have a vehicle unstable to be able to slide away from a parked position. This is such a road hazard, something has to be done about it. It's not far that I am expected to pay for these faulty wiring costs out my pocket when its a faulty issue GMC is very well aware of.

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.

I have been having issues with shift to park message for a yr now and it just gets worse and do not have the funds to pay for it myself bu5 see that it is a recall and gm is covering cost for other makes models of my same yr for same issue takes sometimes 20 minutes to mess with my shifter until I can finally park my car where it shuts completely off. This is a safety risk as 1 it could roll away if it isn't 2 my car could drain and die leaving me stranded by not turning off fully one time. This is ridiculous I called gm and all they just pushed me off I don't understand how this is not being taken serious especially knowing this is a known problem!

Shift to park message has appeared again and the engine will not cut off. First happened in Feb 2020, mileage was 31,143. Took to Dealer and new wiring harness was installed. Had to take back to dealer April 2020 for same problem; shifter assembly was replaced at that time. Shift to park message came back on August 2023. Took back to Dealer and shifter harness replaced again and jumper harness was installed. Mileage was 52,993. Shift to park message has once again appeared, December 2025. Having to put car in park and push engine on/off button numerous times before engine will finally shut off.....sometimes having to unhook battery in order to kill the engine. This will be the fourth time we have had the same recurring issue repaired. My husband read through over half the 352 registered complaints and at least three fourths of them were all about the SHIFT TO PARK problem! As a female, I don't feel safe driving my Acadia not knowing if the engine will cut off or if it's actually in park or if the car will roll. Why can't GM fix this issue!!!!!! They should definitely be held accountable instead of ignoring the complaints!

The contact owns a 2018 GMC Acadia. The contact stated that after shifting to the park(P), there was an audible warning alarm activated, and the message "Shift to Park" was displayed, and the vehicle failed to immediately turn off. After restarting the vehicle and jiggling the gear shifter, the failure was corrected. The vehicle was taken to the local dealer, who diagnosed the vehicle and determined that the gear shifter assembly was faulty and needed to be replaced. The vehicle was repaired, but while picking up her daughter from school, the gear shifter was shifted into park(P), and moments later, the vehicle started rolling backwards. The contact had to activate the parking brake to stop the vehicle. The vehicle was later towed back to the dealer. The cause of the failure was not yet determined. The manufacturer was not notified of the failures. The failure mileage was 120,000.

I have owned this vehicle less than 5 years and it has had the "Shift to Park" error 3 times and has now been replaced 3 times. The 2nd time was in August 2023 and yesterday it had to be replaced again. I don't understand how a part can fail this rapidly when the vehicle is only being driven approximately 10,000 miles per year. It only has 82,445 miles. I would like for GM to issue a recall for this issue or advise who the manufacturer is of the Switch part number 84955381 and Harness part number 84733196. The parts are not that expensive but the labor to replace was $ 462.50 and total parts was $ 55.56 on the invoice yesterday. As this is an ongoing issue I would like reimbursement. I am widowed and living on one income.
