My 2017 had a shift to park issue. When parked and the car is in "park" the car will say "shift to park" which causes you not to be able to lock the car, or to make sure the car will not roll away. Took the car to the dealer and had all components replaced, however they information me that this will not fix the problem as the parts are made incorrectly, so unfortunately it will happen again at some point. My second issue with the acadia is when you are in cruse control, the car will automatically apply the breaks (abruptly and hard) for no reason. Gmc says that it could be when the sensors get dirty or overheat, however it makes you very uneasy knowing your breaks can mash on at anytime by themselves when you are using the cruise control system.

While in motion on a city or freeway approximately 35-70 MPH, my gmc acadia will randomly disable the steering assist, lane keep assist, and forward collision automatic braking as well as disable the cruise control feature. The error would show that these features were disabled on the display screen around the speedometer and could not manually be re-enabled with the buttons throughout the car. However, when pulling over and turning off the vehicle and restarting it, the feature would reset as if nothing has went wrong. Sometimes it will revert back to the same issue(s) 5-10 minutes later, and sometimes not at all for a few days or even weeks before starting back over again with the same problems.

When shifting the vehicle to park and then shutting off the engine, I get an error message 'action required- shift to park'. The vehicle is already in park! I've had to jiggle the shifter, press the brake while jiggling the shifter, restart the vehicle put in reverse, then back in park, and jiggle some more. The radio and lights (both interior & exterior) will not power off and the door chimes nonstop. This happens randomly and it has been a little over a month since the last incident which occurred two days after I had to replace the battery because I missed the error message heading in to work. The last 2 days my husband has disconnected the battery because nothing will work to power off radio & lights. I've had to replace the battery twice now in a new vehicle leased in 2016. The first time was due to brake recall, my vehicle being the only 2017 gmc acadia denali effected by that recall. The brake lights would remain on because the brake was basically sticking, draining the battery. That issue also disabled the cruise control as that feature is unavailable when breaking! This vehicle also had repair to wiring in driver side door due to water getting into the door frame from outside and corroding wires causing detection issues with the key fob. I could not unlock my doors without removing the key to manually unlock. While in the car wash, the vehicle lost connection with my key and the driver's seat moved all the way back as it would for easy exit which I had disabled. Message stating key not detected wouldi was told a needed a new battery in my fob, dealership replaced, called & said everything was working as it should. They ran the vehicle through the car wash before I arrived to pick up the car. When I tried to unlock the doors, the vehicle would not recognize the fob. Thank goodness the service rep was there to witness the malfunction.

Tl* the contact owned a 2017 gmc acadia. While driving with the cruise control set at 60 MPH, the contact attempted to deactivate the cruise control, but was unsuccessful. The contact also attempted to deactivate the cruise control by depressing the brake pedal, but that failed as well. The contact had to steer into a concrete barrier to stop the vehicle, which caused all the air bags to deploy. The contact sustained injuries to the left shoulder, ribs, and a broken tooth, but did not seek medical attention. Police report number: 2018809633 was filed. The vehicle was towed to an unknown dealer where it was deemed a total loss. The cause of the cruise control failure was not determined. The manufacturer was made aware of the failure and case number: 8-4427699189 was opened. The failure mileage was 27,200.

The adaptive cruise control (acc) in my 2017 acadia denali will shut off and even cause the vehicle to break for no reason. This has happened numerous times, even with no other vehicle on the road or obstacles in the road. When it happens the acc will shut off, you will hear two distinct chimes and you will see a message saying, 'adaptive cruise control disengaged'. After this happens you will not be able to reengage the acc and if you try the vehicle will display a message that says 'temporarily unavailable.' I have had it to the dealership numerous times and they have stated they don't know why it would happen, and cannot do anything unless they can duplicate it. It happens a lot but the dealership and gmc say there is no problem. The first time this happened it almost caused my wife to wreck, since the acc shut off and applied brakes with no other car on the road, badly startling her, and she thought she had hit something. I even have a video of the acc showing 'temporarily unavailable' after one occasion it shut off and slowed the vehicle. In this instance there were no car in front of me or on either side, but there was one behind me who I am sure was not happy when the vehicle in front of him braked for no reason. A gmc representative told me I can have all the video I want, but it 'doesn't matter and won't change anything'. The dealership did do a complete diagnostic on one occasion and found evidence that the acc had shut off, but the code did not say why it shut off. This has happened at different speeds range from 55 to 75 MPH. We have had it happen three times in a 30 minute period and drove for a month without it happening. This causes an unsafe driving experience and should be fixed or the vehicle replaced. I have found other people online who have experienced this, but there are not enough of us to warrant gmc doing anything.
