When the vehicle is shifted into park and the ignition is turned off, an error message is shown saying "shift vehicle into park". usually pushing the shift knob forward and releasing it will make the error message disappear but there have been times that the vehicle had to be turned on and off multiple times as well as shifting from drive to park multiple times to make it go away and turn the vehicle off.

The vehicle sometimes fails to recognize that it has been put into park, flashing a message on the dash instructing me to 'shift to park' even when the gear lever have already been moved to the 'P' position.

I shifted the gear into park, and a message appeared saying to "shift to park" and wouldn't allow the car to be turned off or its doors locked. This is a safety issue because the car is unable to shift into park and could roll back.

Recevied "action required - shift to park" message on instrument panel screen. Motor turns off but vehicle stays in accessory mode and chimes continuously. Dealer replaced wiring harness that promised to fix the problem, went away for 1 month and came back. Jiggling the shifter or flicking the shifter button is the only way it will go away.

Experienced the "vehicle not in park " when shifter was in park. Engine would not turn off because electrical switch did not recognize the vehicle was in park. After many tries I was able to turn vehicle off. Had vehicle serviced and shifter was replaced (3 weeks ago ). today shifter froze in park yet console indicated vehicle was in drive. Did not remove foot off of brake because vehicle would move forward because it was in gear. Could not shut off vehicle because it is a push button start/stop and foot must be off brake to stop engine. Called dealer for help. Finally we put emergency brake on and pushed stop button. The engine turned off but electrical system was still on. Had vehicle towed to dealer. They will advise in a week or so they are short handed.

The vehicle will not always go into park. In order to get it into park you have to repeatedly shift out of park and back into park until it will go into park. If it is not in park the vehicle will not lock and will not power down. Since it will not go into park if the vehicle was on a hill and it did not go into park then it would have the chance to roll down the hill. I have not attempted to see if it will roll down the hill nor am I going to try but seeing how it shows on the instrument cluster that the vehicle is in neutral I'm sure it will roll if given the chance. When shutting off the vehicle after you have put the vehicle in park on the gear selector a message comes up on the screen that says shift to park it has taken up to 20 tries of shifting the vehicle in and out of park until park will engage. As you can see in the picture all gauges are at their lowest point showing no power to the vehicle and the shift indicator is in the neutral position with the message on the display reading shift to park.

Took our Acadia in on 9/25 after several weeks (started the week of 8/26) of the shift to park indicator light kept coming on. The dealership had it for several weeks (P/U 10/16) because they couldn't get the parts due to the GM strike. We have had it back three weeks and it has begun again with the shift to park light. We keep the parking break on just in case, don't trust it. Have another service appointment on 11/15. We will see what happens.

When putting vehicle in park, message comes up on dashboard "shift to park." Sometimes takes multiple attempts to get vehicle into park so vehicle can be turned off. Have to shift between drive, reverse and park or wiggle shifter and pump brake to get message to go away.

1 out of 2 times a day when I put the vehicle in park it gives me a warning to shift to park on the electronic dash. Even though the shift is sitting in the park position. So I have to restart the car, take it out of park and shift back to park multiple times before the warning goes away. This warning prevents the car from completely shutting down

Warning message says "shift to park". message does not go off until you turn car on and off several times; putting the car in reverse, then drive; then shifting between gears back and forth. May take 20 minutes to get the message light to go off. GMC has tried replacing gear shift, part of gear top. After 5 attempts in trying to fix the issue, my car sits at the dealership for an additonal 4 weeks waiting for a harness fix (which there is no part for). The car always rolls backwards when the message finally goes off. This is a major safety issue. Is the car really in park?

Vehicle engine was running when I came to a stop and shifted to park. I received an error indicating "action required - shift to park." I did not let off of the brake pedal because I was unsure if the vehicle had actually shifted into park. With the brake pedal applied, I attempted to shift to neutral and drive, then shift back to park, and received the same error. With my foot still on the brake, I turned the ignition off, but the electronics would not power off and the error continuously displayed on the dash. I started the engine and repeated this process multiple times with the brake pressed before changing gears again, shifting into park, then applying the electronic parking brake with the engine running. It was only then that I turned my engine off again, and the error finally no longer displayed. Since the error was no longer displaying, I could only hope that my vehicle was actually in park, but felt reassured that the electronic parking brake was engaged. Please investigate this safety concern that seems to be affecting many of these vehicles.

We have an issue with the gear shift, since three weeks ago we can't turn off the engine as a normal procedure because the sensor of the gear shift doesn't detect the shift is in 'P' parking, we continually receive a message from the screen. 'put your shift in 'P', but in this precise moment the shift was in parking mode, so we can't turn of the engine. We receive a notification from the mechanical workshop that the issue could be the electrical harness, but they doesn't give us when could be changed, so right now we have more than two weeks without use the vehicle, they do not receive a official feedback for the plant yet.

After shifting my Acadia into park and shutting it off, "shift to park" warning comes us sounding an alarm that won't go off unless I start the car and shift in and out of park several times. It gets harder to get the warning to go away each time I drive it. I have had to result to not driving it to avoid the battery draining or having to unhook the battery. The car only has 19000 miles so the dealer is willing to replace it but there are no parts available. Also, others have mentioned that the problem returns even after the repair.

Shift to park notice. When attempting to turn off vehicle and shifted into park, vehicle will give a warning that vehicle is not in park. At this point I have no idea if the vehicle is in park or not. Not sure if I am just receiving a faulty notice or is the vehicle not in park and could roll causing injury! this is not a safe vehicle. GMC unable to repair due to not having the part available. This may happen for two or three times. It has happened that I have had to turn my car off and back on up to seven times before it registered as in park.
