Place shifter in "park", turn off engine, and get "shift to park" message on console. While message is displayed, the car constantly beeps, warns, lights not turning off. Have to start the engine back up, and place the shifter into drive and then back to park. Sometimes have to do this 5-10 times in order for the car to turn off. This first happened at 11K miles (under warranty) and dealership fixed. I am now at 16K miles and it is happening again (out of warranty this time).

Every time I put the car in park position the car doesn't sense that it's on park and error message keeps appearing in the screen saying 'shift to park' and the car refuses to turn off and it roll away from the drive way and I have to shift it back to drive and again to park again and again multiple times till the sensor feels it. It's a safety hazard. I looked up the issue online and found out that most of this car owners experience the same problem and there's multiple lawsuits against GMC for this issue. This car is driven by my wife most of the time and she has my kids with her in the car. It's a life threatening issue! I took the car last month to the dealership and they refused to fix it for free because the car went out of warranty by only 2K miles, and I couldn't take the car to the dealership when this issue started because of the covid. By the time we could visit the dealership we already drove over 5K miles and that puts the car outside the warranty limit.

The transmisduon shifter when shifted into park, the information center said vehicle not in park and it will not let me shut the car off it was a 400$ repair at the GM dealership not covered under any of my warranty
Whenever the vehicle was put in park and I attempted to shut it off, it would give me the shift to park error code and would not let me cut the car off completely. It would happen just about every time I drove it. I just got it out of the shop for the third time and was told this time they replaced the assembly. So far it has not happened again but it has only been a week. It started back in January 2020.
The car would not turn off when put in park when the car was stopped. The engine would turn off, but the electrical devices (lights, radio, odometer readings, etc.) would remain engaged. The warning indicator said the vehicle was not in park and it would take 5-10 minutes of turning the engine on and off, and shifting back and forth in and out of gear before the car would turn off completely. A search on line indicated several people complaining of the same issue. This car is 2 yrs old with less than 40K miles. It was maintained as a company leased vehicle by us before being purchased by us, so we know it has been properly maintained. We ended up having to have the shift column replaced.
My car keeps giving notice of it not being in park, when its clearly shifted into park. It wont shut down, let you lock doors. Just beeps until it finally realizes its in park. Even after continuously re shifting into park. Worse in the summer months. It needs to be fixed as many others are having the same issue!
When I shift the to park and try to turn off my car the shift to park lights up and I have to down shift and then shift to park again to get my car to shut off also the air compressor has already quit working with less than 40K miles on it.
