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.

This issue has happened 3 times now and is becoming a safety concern for my family and I and for others on the road. I purchased the car brand new in May 2017 and the issue occured for the first time on October 02, 2017. Second time was February 15, 2018 and the third time happened around early April 2018. While driving at a slow speed (entering a parking lot, in the middle of an intersection when I was about to make a left turn on a green light, and while driving in a parking lot after getting gas) the car made a grinding/clunking sound and was brought to a very abrupt stop. I tried to press the gas but the car would not move. I changed the gear from drive to park and then drive again and would still not move. I turned the car off and then back on and still nothing. I ended up figuring it out by pressing the parking break button 1-2 times and was then able to proceed to drive. It seems as though something may have triggered the parking brake but while I was in drive and while the vehicle was moving. I was almost rear ended when this happened in the intersection and also during the time I was unable to move in the intersection, my light had changed to yellow and then red and oncoming traffic was honking because they could not go on their green light due to me being stopped in the intersection. It was very scary and dangerous as it almost caused an accident 2 out of the 3 times it has happened. I told service dept at the dealership about it twice. They have "looked into it" one time but since they were not able to replicate the issue (obviously), there is nothing they can do. I am concerned about my families safety if this continues to happen.

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.

I brought it in to service department a couple months ago because the accelerator would accelerate with out me pushing the gas even slamming on the brakes would get to 85 90 miles an hour. Finally got it off the road and off huge quantities of white smoke from the brakes being so hot. Assured me it was fixed and last night in highway traffic did it again. Almost got me killed. Service said there was no recall but this is very dangerous!

Adaptive-cruise-control (acc)/forward collision braking(avoidance) system applied very strong brakes(twice) in certain scenario when using acc, increasing the chances of vehicle behind rear-ending. While acc is enabled, say your vehicle comes to fullstop as vehicle in front has come to a full stop(say at traffic signal) and acc applies full brakes. Traffic ahead starts moving again, but since vehicle won't move on its own driver is required to press accelerator to get it moving again or acc to resume its operation (this is by design). In such scenario if driver ends up pushing accelerator a bit harder(I.e. more than just tapping it), acc applies very strong brakes stopping vehicle right there. By this time vehicle behind you has started moving already and might rear-end due to abrupt stop. I guess acc thinks distance between you and vehicle ahead is very less and thinks its going to collide and hence applies strong brakes. But this is a bad design/programming since it expects driver to push acc. Pedal for acc to resume operations, but if driver does it bit more than what acc likes, there is a chance of accident. GM should perform more tests with its acc around such scenarios and fine-tune their acc software.
