After being parked for over 24 hours, when we started the vehicle we got a message shift to park. The car would not go into gear and was undriveable. We tried to contact onstar from the vehicle but thd connection kept breaking up. We got through on our cell and were forwarded to GM. They ordered road side assistancece. While waiting, we again started the vehicle. There was a bew message initializing: Wait to shift but the car did not go into gear. When roadside assistance arrived, they also tried without success. The car was towed to a dealership. In reading various forums, it appears this is a common problem and a major repair. I am curious as to why there has not been a recall fir this issue?

It is very difficult to shift into park. Nearly have to push hard to have the park setting engage. Unable to turn engine off when this happens. Also, the window will not go up smoothly. It goes up and down all on its own. It appears to have a mind of its own. You must open the window all the way before it will close. Cannot preform that function when it is only partially opened.

Shift to park issue. It will not go into park and allow car to be turned off. Progressively worse. Major safety issue. Chevy says this VIN number is not covered under warranty despite fact it is a known problem.

I am having a 'shift to park' issue. When I stop the car and shift to park, I attempt to power off the car. The Volt will not power off and I get an alert on the dashboard that states "shift car to park to turn off". but the car is already in park. I am unable to lock the car and the lights will stay on for a few minutes. Worse yet, it is intermittent. After multiple attempts at re-starting and stopping the car if usually turns off. My Volt has only 28K miles.

With the vehicle stationary and gear shift set to park, when attempting to power off the vehicle, a 'shift to park' message appears on the dashboard. The vehicle does not power off. After several attempts of changing the gear shift to drive and back to park, the vehicle powered off.

When shifting into park, and depressing the start button to turn off the car, I see a "action needed: Shift to park" message on the dash. Some times I can shift the car back into gear and shift back, or sometimes it just lets me turn it off. There are numerous reports of this issue on the internet requiring replacement of the shifter assembly, with a faulty sensor being the culprit in the full assembly. This affects both Chevy Malibu's and Chevy Volts in the same model generation.

Since purchasing this vehicle in mid-2020, I have experienced this issue on several occasions including again today. I understand there is a technical service bulletin out on this issue currently.

The car does not turn off completely and shows "shift to park" when the transmission is in park mode. It is a common issue but Chevy does not recall and charges consumers for out-of-warranty vehicles.

Shift to park warning on dash

Can not turn engine off after parking the car. The message "action required" 'shift to park' shows up even though the car is in P and parking break is also applied and the vehicle is stationary. Has been happening everyday the past week. Have to leave the car until it turns itself off!

Shift to park issue- when car stopped and gear shifter placed in "park", car does not recognize this and cannot cut off ignition, showing "shift to park" on dash. After jiggling gear shift a lot and putting it in and out of park multiple times it finally resolves. After searching on web, this appears to be a common issue in 2017 Volts.

Prior to starting my 1,100 mi trip with my 2017 Volt premier, I inflated the tires, checked fluids, & charged the car. The monthly diagnostic report I received the day before my departure indicated no problems with the car, which had approx 40,500 mi. I was driving on interstates & highways using hold (gas) mode, occasionally mountain mode. Approximately 275 mi. Into the trip I received power propulsion reduced alert. After an additional 50-75 mi I received an action required: Engine overheating reduce speed alert. I exited the interstate and proceeded to the nearest dealership to determine if it was safe to continue on my trip. I was told that the propulsion alert was not an immediate concern & that the overheating was likely not related. I also received a GM diagnostic E-mail stating there was an emissions problem that should be serviced within 7 days, but did not become aware of this E-mail until a day later. Approx 200 mi later, I was on a remote, unlighted highway when I received an engine unavailable alert and lost power. My car quickly decelerated, but I was able to get to a narrow shoulder. I tired to put the car in park, apply emergency brakes, and shut the car down but it was difficult to tell if these features were working. I put the hazard lights on and waited for a chp officer due to lack of cell service & highway safety concerns at night. After 3 hours, all systems failed, including lights. Only manual locks worked. After two 30 mi tows to get to a dealership with a Volt tech, it was determined that a bad egr valve was causing a fuse to blow, . the valve was ordered (tech remarked that the part is "popular") & installed. The issue seems to be fixed. But, it is unclear if this is a design flaw, manufacturing flaw, or a one time occurrence.

Chevrolet "shift to park" defect. Can't power off car or lock doors because vehicle indicates it is not in park, despite correct shift position. $400 to replace part on car with 45K miles. Part not covered under drivetrain warranty. Problem happening across Chevy models Volt, Malibu, traverse, acadia etc... newspaper articles and users complaining on Chevy forums. No reason for something with so little use to be failing so early on vehicles. Chevy owes consumers a recall.

After completing driving and then shifting to park, the vehicle won't shut down after pushing start/stop button and gives an error message to 'shift to park' even though it's already been shifted to park.

- Eagan, MN, USA

For the second time in three years this car fails to turn off when in park. Instead a message is displayed saying "shift into park" even though the car is already in park. Last time it required the replacement of a switch in the shifter. The car is no longer under warranty and it is happening again. Happens almost every time the car is turned off and sometimes happens over and over before I can get the car to actually turn off.

- Templeton, CA, USA

Shift to park issue is present and getting worse. Unable to turn off car when it occurs. As this is common to this model it should be treated as a direct and GM should repair as part of a recall.

- Las Vegas, NV, USA

Shift to park message is displayed even though the car is in park, making it impossible to turn off the vehicle. The dealer replaced the transmission control and installed an updated harness to resolve the issue. Based on google searches, this appears to be a very common issue with the Chevy Volt.
