Vehicle will have a message on the dash that says -??drive with care steering assist is reduced-??, the fans will come on and stay on, and the temperature hand will quit working along with air conditioner. It has not been inspected, I am not sure if the steering assist being reduced could cause any harm to myself or others.

When I put my 2019 GMC Acadia in Park shut the car off get a message to put the car in park. The radio does not go off, not able to lock doors. Displays that message. Have to keep putting it out of the park and after 5 or 10 minutes message finally goes off and it will let me lock doors. These last couple days it had done it every time I drive

The Rear Hood was opened to get groceries. All of a sudden the hood came down on my back. I had to push the hood up manually, and tried to close with remote or with button on the hood but the Rear hood would not close. I then had to manually close the hood. On August 11, 2021 I took the car to the dealer and they replaced both Rear Hood Struts that wear leaking fluid. This SUV is only 2 years old with 16000 miles and should not be having these type of safety issues that can potentially be life threatening.

When I put Shifter in PARK, the dash indicator states the car is in PARK. I then push the Start/Stop button to turn the car off, but the dash displays car is not in PARK. Sometimes the car will not shutoff or the car just beeps until I push the Stop/Start button. I cannot lock doors to leave the car. When this occurs or when left in this state the battery runs down, which leaves me stranded. This is certainly a safety issue on various levels. It the car really in Park! What if it on a hill and starts to roll into me or someone else.. Scary!!

We are experiencing the "SHIFT TO PARK" issue on our 2019 GMC Acadia at 44,000 miles. We have been told we need to pay $200 for the fix PLUS more than $200 for the battery which has undoubtedly been impacted by the first issue. Needless to say, we are not happy that we'll be charged for a known GMC issue and we are aware there are class action suits around this issue in various states. We have been loyal GMC owners, but we are now concerned about the safety issues this presents our family. Ironically, we are searching for a new truck at this time and this recent hardship will impact our brand choice now as well as in the future. Please let us know how this issue might be rectified.

After placing my car in park, and trying to cut off the engine, it alerts me to "shift to park"... I will have to restart my engine, put it in neutral and then back to park, and try again to shut off the car. Sometimes it works on the second attempt, but usually takes 3-4 times of cutting engine off and on, shifting from park to drive to park again. If you attempt to exit the vehicle, the horn will start to honk, and alarm goes off. The car is clearly in park, the shifter can not move forward any further, and the indicator says its in "park" it is only after you press the start/stop button that the alarm indicates it needs to be "shifted into park"

First time back in June 10th, 2020, I took it in because of "remote not detected" they could not duplicate the problem, few hours later, same day after I picked the car up it went haywire while parked. It threw itself into theft mode, would not let us manually lock the car, electrical was still on but engine was shut off, alarm, windshield wipers, and lights was going off while I had it towed to the dealership. This time they've told me, the A/C condensation fried the cpu module because the only thing keeping water out of the cpu was a tray. September 9th, 2020 I take it back into the dealership because again the car kept reading "no remote detected". they claimed it was my "dash cam" that caused the issue. October 14th, 2020 the car again went haywire while in motion. This time it threw itself into theft mode, alarm went off, wipers, was reading low fuel (full tank) steering assist turned on and off, brakes started locking mid busy street, steering wheel tightened also. I barely could turn it into a neighborhood street to get off the road. I had the vehicle towed back to the dealership again, through my triple a plan for the second time because I was "out of the area" that they could send a tow truck to. They tell me again condensation got into the cpu and wasn't even sure if it'll happen again if I continue to run the A/C. I picked the car up the next week and on October 25th, 2020 the car again would not read the keys. Every incident but October 25th, 2020 incident, I have let a supervisor from GM know of the situation, his name is [xxx] ext. I have recorded even phone records of every incident that's occurred.

After jump starting car because of dead battery decided to drive to dealer 1-2 miles awa.Y. my wife followed me in car. While driving during the 1-2 mile trip the stearing would lock up (quit working) and the breaks as well.this lasted several seconds and resulted in total lack of control at 35-45 mph on a city street. The alternator was working providing electricity to the cars systems. As batteries frequently fail I believe this is a clear and present danger to the occupant and other vehicals on the road.this occurred on Sunday October 17, 2020

I have had fading on the plastic around the wheel well, the heat will change to cool air while driving without anyone changing it. The A/C will go full blast on it's own and then all of a sudden change the fan speed without anyone touching it. The dealer has told me it will adjust itself by 10 degrees, never heard anything like this before. The fading part they just painted over it and that was the fix. There are lines in it now and they did not paint the entire piece so it does not look right. This car is parked inside when home, this should not happen. I have had this car in the shop way too much since I bought it with dents happening on parts all over. I drive to work and back mostly. 2 dents have happened in the dealer lot when they had it outside waiting on repairs. Would not buy it again.

I have experienced issues with the shifter of the vehicle twice now and it has resulted in replacing the shifter at least once. 6 months later and after an initial replacement the shifter has gone out again. The shifter refuses to move out of the park function. Prior to the shifter going out the car would say shift to park even though the car was already placed in park. I believe the issue to be an electrical problem. The middle seat belt in the second row of the vehicle has also stopped working.

Shift to park. My vehicle tells me shifter is not in park when it is. I was informed there was a recall. This is my going to be the third time they fix it. This vehicle carries my kids to school and work on a daily basis, I don't feel very safe driving my family in this vehicle.

Car automatically shuts off when driving multiple occurrences of this happening

- Kansas City, MO, USA

I turned the car off and it displays a message 'shift to park, ' even though the car is in park. It doesn't allow the car to shut off completely. The engine turns off, but the electrical stays on. When we try to drive it, it is slow to accelerate and the rpms shoot to 4 and don't go down unless breaking. Finally the car will not accelerate past 55mph and the rpms stay at 4, with the engine being very noisy. This left us stranded an hour from our house because the vehicle is not safe to drive. Fortunately this occurred in a parking lot. We drove a few miles to try to get to our dealership, but did not feel safe driving.

Shift to park is happening on the 2019. When in park, its not being sensed. Keeps saying shift to park. Took vehicle in they said 1/2 a day on 11/22. Turns out they need longer for part. They gave loaner, today is 12/4/19, still don't have car back yet. Also, back windshield wiper making a clicking sound.

My mother has become trapped two times due to the locks on the vehicle not working. The issue only happens when it rains. I took the vehicle to the dealership and they said they replaced some kind mechanism and that everything was good to go. It rained again yesterday and my mother was trapped in the vehicle again. This happens anytime you try to engage the locks, I.e. in park, putting it in park, putting it in drive, using onstar to lock or unlock, using the GMC app to lock or unlock, using either key fob to lock or unlock, trying to lock or unlock it manually.
