My -??Shift to Park-?? warning light pops up when attempting to park the car and shut off the engine. My wife had the problem at the grocery store and was very upset. This problem is constantly happening, my wife refuses to drive the car. I called the GMC dealer to get it looked at and was told it would be 2 weeks until they could diagnose the problem. Also it would cost $150 to look at it and I see the repair could be between $400 and $2000. The warning lights won-??t stop and the constant bell dinging won-??t stop until the battery is dead. All anyone has to do is Google -?? shift to park-?? to see this is a defective switch. Many states have filed class action suits. A recall needs to be issued. My car has 33k miles on it.

Shift vehicle into park and then turn vehicle off. Warning light comes on which says "shift to park." Turn vehicle back on. Move shiftier from park to drive and then turn vehicle off again. Warning light comes on and warning "shift to park." Do this a few more times and it finally the warning stops. It does this intermittently.

I have numerous warnings, shift to park, steering, cross traffic, this endangers myself and anyone else around me, i have read several class action suits involving these problems and it could cause my vehicle to pose a danger, I have taken my vehicle in to a certified dealer and they state there is no known recalls associated with my vehicle which is strange because GMC knows that there are thousands of vehicles having the same problem, did I buy a lemon? These problems are clearly manufacture related and in no way normal wear and tare. I should not have to compensate these issues when I paid near 40,000 for

When I put my car in park and turn off it will randomly say "shift to park" it started doing this in Aug or Sept 2019 the car was under warranty and I brought it to a dealer to "fix". fast forward April 2021 it started to say shift to park again and car is no longer under warranty. Called different dealers even the one I brought the car to fix problem (that was a joke), they know its a problem and saying since that part got fixed in 2019 with a bad part and now there is a a newer fix that should work better, but I will have to pay for diagnostic test and part again. Again they know it is a problem with these cars and it needs to be recalled. I have to turn the car off and on reshift, push the shifter harder, etc to get the message to go away so I can turn my car off.

Will say that vehicle is not in park and will not shut off. Constantly says remote device not detected despite me using the remote to start or turn the vehicle off. Will not officially turn off saying remote not detected and radio will stay on. I can use the remote to turn it back on but the receive the same error message, this happened 4 times when we parked at the ball fields Sunday. How frustrating that we had to hang by the car hoping the next try it would cooperate. This is clearly a problem that GMC needs to fix. These are not one time errors, I have some type of error daily.

Vehicle when put in park does not shut off. Took to hillsdale GMC 1/13/20 and it was okay for awhile. This same problem started about 3 mo ago again. Put in park will not shut off. You may have to restart, pull into gear, back to park, over and over! very annoying especially if you have an appointment!

Shift to park error, on computer display.

My 2018 GMC Acadia was bought new. It has an issue with the shifter regarding "shift to park". when the vehicle is placed in park the sensors or computer does not recognize it and you have to shift in and out of park to get it recognized. My car has roughly 42ooo miles only and was stationary when this occurred. I called my local GMC dealer in New Jersey and they said it was not under recall, it is a known electrical short and my vehicle is not under warranty. They wanted 400.00+ to fix the problem or issue. Upon an internet search I learned that this is a common problem with this model. I feel as a consumer that GMC should generate a recall on this issue regarding "shift to park". thank you

Vehicle does not recognize when it is in park. At times vehicle will not go into park and makes me concerned for my family's safety. My understanding is that GM is aware of this issue.

When trying to put in park won't shut off says shift to park, started around 25,000 miles have to be sure vehicle is level and not on an incline. Vehicle also surges at times loosing power when you're going down the highway. Also, at times when you go to start vehicle it will hesitate and disconnects from battery thus resetting everything. Had to replace battery at 25,000. The rear wiper will go on it's on without turning it on.

Shift to park when I attempt to turn off the vehicle. Won't go off and can't turn the vehicle off

"shift to park" issue. When our 2018 GMC Acadia is placed in park, the dic displays that the vehicle is not in park when it is indeed in park. Never sure if transmission is truly in the park position and cannot roll, but there is no confirmation of this. This indication failure prevents us from leaving the vehicle for a substantial amount of time until we (if ever) see the proper "park" indication.

2018 GMC Acadia shown 'shift to park' message even car is stopped/ parked.

- San Francisco, CA, USA

Every time I park and try to shut car off the car refuses to turn off and gives a message that says shift to park. Requires 20+ attempts of restarting, shifting out of park and back into it before succeeding. Car is clearly in park, not rolling but I'm unable to turn off car fully. This has been occurring the last month or two. I bought the car brand new.

When you shift into park, the chimes start going off and the dashboard message says 'shift into park'. I have to wiggle the shift until it shuts off. Sometimes it takes a lot more wiggling than others. This happens about 90% of the time. This has happened since we purchased it.

- Youngsville, LA, USA

When I try to turn off my vehicle, my dash displays the message 'shift to park' even though I'm already in park. I have to jiggle the shifter nob back and forth to get it to recognize it is in park. It's happened about 80% of the time I try to turn my car off for the last couple of weeks.

- Adams Center, NY, USA

The vehicle fails to detect when I move the transmission shifter into park position. I have to try to turn off the car and turn it back on and sometimes have to drive in in it again and then attempt to shift it to park and shut it off again. Sometimes it won't shut off, and then I'm stranded.

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!
