When attempting to turn the vehicle off after parking, the driver's console displayed the message "Action required: Shift to Parlk". The shifter was already firmly in the "Park" position. Moving the shifter back to "D" and then back to "P" did not resolve the issue. Pressing the power button twice more resolved the issue this time without further moving the shifter. This is a well-known and well-documented issue with "Gen 2" Chevy Volts.

Shift to park defect. When I try to turn my car off it won-??t completely shut off, a notification on my dash says -??Shift to park-?? but my gear shift is in park already. It takes 5-10 times of me cutting car off and on for it to finally completely shut off.

When turning vehicle off, it will display a message "SHIFT TO PARK" even though shifter is in the park position, the vehicle will also remain on. Sometimes have to jiggle the gear shift or shift back into park a few times before the message goes away and am able to turn vehicle off. This is very dangerous as if it's left unnoticed in a garage the car can be left running potentially filling the house with fumes. Can also run out the battery and gas and leave you stranded if away from your home.

Need to hit power button again in order to shift out of park to any other position (N, R, D, etc.), then shift back to Park and hit power button again.

Ntsb should require a recall of certain Chevrolet Volts. As an owner I received a letter from Chevrolet stating that my Volt 'may have a condition where it could gradually lose the ability to maintain voltage. If battery concerns are not addressed, over time the vehicle could enter a reduced propulsion mode while driving, or lose propulsion, or it may not start.' Losing propulsion while driving is a serious safety issue, and warrants a recall. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)
