Shift to park malfunction. When I put car in park, “shift to park” lights up and beeps. I have to wiggle the gear shift up a bit to get it to go off. Takes several minutes at times. This started about 4 days ago. I have an appointment at the dealership tomorrow. 68,300 miles on my vehicle. When I researched, several others complained about the Acadia’s shift to park malfunction.

Transmission flares going into and out of second gear cause to vehicle to feel as if its about stall out. Especially on hills. I had a vehicle almost run in to the back of me because of the decrease in acceleration.

In August 2021, I placed my vehicle in park and pressed the vehicle on/off button and received a message on the dashboard that stated "Shift to Park", even though the vehicle was in the off position. I was unable to turn my vehicle completely off (remained in auxiliary mode) and unable to lock the vehicle. I took my vehicle to a Chevrolet dealer who notated the issue was inspected and verified with a repair procedure under TSB 19-NA-206. The service record reads "This condition is caused by the park switch in the transmission control not pulling BCM signal low to electronically show part position. Removed and reinstalled transmission control, installed new shifter harness and added wire harness jumper". In February 2024, the repairs completed by the dealer failed again, and this time the entire shifter (transmission control) needed to be replaced. The TSB that GM has put forth does not "fix" the issue, just puts a temporary band-aid on the problem until the vehicle is out of warranty and the customer is forced to pay for the repairs themselves. Without the vehicle registering it is park, the vehicle stays active and the customer is unable to lock or secure the vehicle, putting the safety of the customer at risk. It is also unknown if the vehicle is actually in park, putting those around the vehicle in danger of getting run over.

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation.”

I read of numerous instances on-line where this same condition occurred in other GM vehicles. I took to Joseph GMC for repair and was charged $855.12 for repair since the car was out of warranty.
