2018 GMC ACADIA Complaints

The vehicle will not shift into park. This is a common problem with this vehicle, many lawsuits. When you walk away one has concerns that the vehicle is actually in park or not.

Shift to park issue is getting worse. I couldn’t turn my car off for hours today. The recall is still pending for this and GMC is doing nothing after thousands of class action lawsuits and complaints. Keeping my car running for hours on end while in park because it won’t turn off is causing electrical issues and using tons of gas. I have to get with an attorney at this point because I can’t use my car lots of the times because I can’t leave it running and unlocked all day while I’m at work or at the store. It’s a MASSIVE safety issue. GMC needs to take accountability and fix these vehicles. This has been ongoing for 2 years now.

When I put my car in Park and go to shut it down, it is not recognizing that it is in park, and will not shut down. I have to spend 30 plus minutes messing with the shifter to try to get it to recognize it is in park when it is indeed in park. I have to start and stop my car a number of times to do so. There have been a number of complaints for this over the years and NOTHING has been done with this. This can be a costly repair as I have seen results in a new transmission.

I am communicating concerns about my 2018 GMC Acadia. I continue to have problems with the Park/shift to park. I have had this problem consistently escalating this year. It was occurring 2 or 3 times per month, now it is occurring weekly. I cannot turn off the vehicle when placed in park. I went to the dealer (FC Kerbeck) in New Jersey, where I was told I had to pay for this problem $515. This seems to be a manufacturer flaw. I think this is a recall part. This is not my responsibility, I did not do anything to my vehicle for this consistent problem. This “shift to park” is dangerous, as it can lock you in your vehicle.

Vehicle shifts hard from 1st and while driving when getting up to speed from 2nd gear and 3rd, etc. Happens every time it's driven.

Power steering reduces and the temperature gage wont work and the fan is extremely loud so it decreases the steering and increases the fan so it can cool down the engine. Others have submitted a recall form for this same problem

When putting my car in park and turn the car off. the car dashboard says to shift the car in park and beeps. I repeatedly turn the car on and off until the car reads it as being in park. or the car will not turn off completely, it will continue to beep, and it will not lock the doors. I have called a GMC dealer about this issue. There is no warning message except to put the parked car in park!

While driving I got the alert in my cluster that “power steering assist reduced”. I also noticed there were many other individuals in gmc forums that have had the same issue.

Vehicle does not recognize that it's in park. Once parked a warning comes on telling you to shift to park. The vehicle does not completely shut off because it does not believe that it is in park.
