    Shift to park notification keeps coming on after shutting off the car. It obviously has been shifted in to park before turning off the engine, but the notification keeps popping up. I have had the shift harness replaced by a mechanic once alreafy. He says this is the GMC authorized fix. IT DID NOT FIX THe PROBLEM! Of course, he'll put another shift harness for me, but what are the odds that will solve anything. GMC needs to come up with a better solution! It is frustrating and time consuming trying to come up with whichever trick will work to make the notification to away. I am not a very happy customer!

    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.

    After putting the vehicle in park, I get a "shift to park" error. The car does not recognize it is in Park, so it will not shut off completely. It takes several attempts of restarting the car and putting back into park before it will recognize it is actually in "Park". This has been happening for several weeks.

    I'm getting the "Shift to Park" message when my vehicle is already in the Park position. This issue first started happening in 2019 and I took it to my local GMC service center to be looked at since it was still under warranty. It started happening again about 2 weeks ago. My extended warranty and powertrain has expired, so I'm concerned that the same dealership will charge me for this repair when I take it this week. If this is a known issue with this vehicle, as evidenced by the scores of complaints related to this issue, why isn't there a recall on this vehicle?
