2018 GMC ACADIA Complaints

The shift to park notification keeps coming on everytime we go to put the car into park. It takes about five to ten minutes shifting back and forth to get the car to shut off.

For the past two weeks, when the Acadia is put into park and the engine is turned off, the warning bell chimes nonstop and a dashboard message appears to put the vehicle into park even though it is already in park. The vehicle needs to be restarted and then put into drive or reverse and then back into park. With irregularity it may or may not work. Sometimes the car must be turned on and off 5 or 6 times before it recognizes that the transmission is truly in park.

The contact owns a 2018 GMC Acadia. The contact stated while the vehicle was parked, the "Shift to Park" message was displayed on the instrument panel. No warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the transmission control harness needed to be replaced. The contact researched and was made aware of an unknown recall; however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 42,187.

All of this has been going on for a while but it's gotten to the point of dangerous. The Shift to Park keeps coming on preventing me from shutting the vehicle off even though it's, in fact, in Park. Then, "Steering Assist Reduced Drive With Care" keeps coming on. This will come on and off. Preventing the engine from heating up like it needs to be. Then the transmission keeps slipping. Was nearly rear-ended on the highway with my child in the car when it decided to start driving really rough and wouldn't allow me to shift to the next gear. This is also an ongoing issue. Another time I was almost hit in the side when this randomly happened on crossing the highway. This is absolutely absurd! I have had MUCH older vehicles without all these issues with many many more miles! I can't count the amount of times this has caused us serious hazards not to mention almost costing me my JOB! Interestingly enough, the same year/make/model has been recalled for the exact same issues yet for whatever reason GMC says MY model "was not affected by the recall". Funny how it's having the EXACT same issues as the ones on the recall list! GMC needs to fix this before they cause people to die! I'm a healthcare worker and this is disgusting!

My Acadia car has been having some problems with the shift to park. I put my vehicle on park and my doesn't turn off because it keeps saying that it hasn't shifted to park. Do to this issue my battery car has been draining and my family and I got locked in. I bought the car not to long ago and it's been an issue ever since its getting worse as time has past. I'm really wanting this fix as it can take hours to turn the car off.

After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was not taken to the dealer or an independent mechanic.

The failure mileage was 60,000.

I have a 2018 GMC Acadia that is now displaying " shift to park " while the vehicle is in park. Upon extensive research I see GMC did issue a recall however, my particular VIN was not included. Its NOW displaying the error message which would lead me to believe it IS part of the recall. I called my local GMC dealership (Langhorne, PA.) and they said this was not covered since my VIN was not issues a recall.

The car no longer recognizes when shifted into Park. It will not allow things like door locks and so on.

The contact owns a 2018 GMC Acadia. The contact stated that after parking the vehicle and shifting to park, the vehicle failed to turn off. During the failure the message "Shift to Park" was displayed even though the gear shifter was in park(P). After several attempts, the vehicle was able to be turned off. The contact also stated that during the failure, the vehicle would roll backwards. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 70,000.

My 2018 GMC Acadia is experiencing an issue with the "Shift to Park" feature. When the vehicle comes to a stop and is put into park an alert comes up on the dashboard says "Shift to Park" even though the car is fully parked. This keeps the vehicle from being able to be turned off. Often times this issue is not fixed by turning the car on and re-shifting to park and i have to drive the vehicle and try again. This happens over 50% of the time I try to park this vehicle.
