Shift-to-park issue. While in park, car shows error "shift-to-park" and electrical parts of the car will not turn off. After shifting to drive/low and then back to park several times, it senses that the gear is in the park location and allows the car to be shut off. However, this has progressively gotten worse over time. Most recent issue took over 15 minutes of doing this to get the car to remove the error and turn off. Issue started around 31,000 miles. Current mileage as of this writing is 34,000.

After I stop the car, put it in park, and then press "power" off, I get an alert on the dashboard "action required: Shift to park" and the car will not turn off despite the fact that it is already in park. The gear shift requires additional manipulation (to be moved back and forth) before the car understands that is in "park".

Action required: Shift to park is displayed every time car is turned off. Multiple times pressing and releasing the shift lock button on the shift lever while also switching gear positions does fix the problem for now. It appears to get worse with time.

The 2017 Volt, when put into park, does not detect it's in park and gives a "shift to park" message. The car will not turn off. I cannot leave the car. I am stuck rolling the car forward and back multiple times until it finally registers it's in park and turns off. This happens intermittantly and unpredictably. I read online that this is a known and widespread issue in the 2017 Volt that GM is refusing to address. They are also refusing to cover it under the powertrain warranty, even thought shifting is part of the propulsion system. I have missed meetings because I have been unable to leave my car. I fear being stranded with a car that won't turn off. This has been happening regularly but unpredictably for all of summer 2020.

Shift to park message appears when you shift to park and you turn off the engine. So even though you are in park the engine will not turn off. Very frustrating!

My 2017 Chevy Volt is experiencing the apparently infamous 'shift to park' issue. Nearly every single time I pull into a parking spot, I put the car in park and press the power button to power down the vehicle. A message pops up on the display that says 'action required: Shift to park.' I then have to depress the trigger mechanism on the gear shift and jiggle the whole shifter before the car registers it is in park and powers down properly. This is a well known problem among multiple Chevy cars but they have not yet issued a recall. My car is just outside of the 'bumper to bumper' warranty, so it will cost a couple hundred dollars to fix an issue that is absolutely not my fault. While I am not aware of anyone having issues with shifting to anything other than park, it is very concerning that this mechanism is known to be faulty. If someone else were to drive my car and not realize they need to jiggle the shifter, they might leave my car on and drain the battery. Every single time I take this to get an oil change or other misc service, I have to show the technician how to get the car to turn off. This issue is potentially dangerous and well known. There should be a recall of the shift mechanism so that all of us can feel safe and reassured while driving.

After driving and when stopped, when car is placed in park, there is a notice on the dash that states, "action required" "shift to park", even though the gear indicator shows the car is indeed in park. Because of this, the car won't shut off and sends out warning beeps from the horn. This could be a safety hazard because the driver does not know if the car is in park or not, and does not know if the car is secure from rolling.

Must shift to park; car will not shut off. Already in park, and pushed very hard to make electrical contact. Shift out and back to park several times to make contact and allow car to shut off. At first, only once a week, now almost every day.

After you power off your car, you'll get an alert on your dashboard that states "action required" "shift to park". I have found multiple complaints on forums as such. In some cases self resolves with a little shake in the shifter. In other cases takes a few minutes to engage properly. This is on going and seems to be increasing in frequency.
