2019 Acadia will be shifted into park and parking break applied. Vehicle will then be turned off. When opening the door a message appears on the dash stating "Place vehicle into Park". It takes multiple times of turning on the car, Shifting into another gear, then shifting back to park for the vehicle to realize it is in Park to allow vehicle to shut off. It has happened multiple times. We then received an email from on-star there is a diagnostic code SAC001 (Battery Service) needs to be addressed. This is unacceptable for a vehicle to be this new and have electrical issues.

I-€™m not sure but a warning came on that said steering assist reduced drive with care and my temperature gage and AC weren-€™t working all of a sudden when it happened

Once vehicle is in park and ignition is shut off, a message will show to "shift in park" when it is in park. When this message appears, it takes several times to shift the car back and forth in order for it to register that it is in park. This occurs occasionally...sometimes more frequent than other times. It just did it today and it hadn't done it in a couple of weeks. The vehicle will not turn completely off or lock until you can get the stick to register it is in park. Sometimes it takes me a second to get the message to go away, other times it takes several mins. Really aggravating! These models are not cheap. This has occurred for well over a year now. I purchased the car November 2019.

After shifting the car into Park and pressing the start button to stop the engine, the message "Shift to Park" appears, and the engine does not shut off. This issue happens intermittently, but it has sometimes taken several minutes of shifting and re-shifting to get the car to turn off.

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!!

"shift to park " message started coming on the display even though the vehicle is in park. Once this message comes on, I am unable to turn the vehicle off. I have to keep putting the vehicle in gear and park again several times until the message goes away. I have video of the issue but dont see where it can be uploaded. There is also a class action lawsuit in conn about this issue.

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.

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.
