We have had our 2019 Gmc Acadia at two different dealershiips, recently we had it at the dealership where we purchased it new in 2019. The door locks keep malfunctioning where they either work or don;t work at times. My wife and child get locked out of the vehicle which is a safety issue.
"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.
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.
Vehicle does not recognize it's in park. Vehicle won't shut down completely,it honks horn and beeps inside and won't let you lock doors or restart car. Haven't noticed it rolling away like many people state... Jerking the shifter seems to get it working so far .. Haven't been stranded yet. Vehicle was stationary in a parking lot
My Gmc was able to go 45 minutes without the key fob I have to have the key fob with me to drive my car and that didn't happen I was able to drive without it
