My car, without warning, lost power while driving and then flashed an engine light. This happened on a street and I was able to coast to safety, but if it had happened in an intersection I would not have been so lucky. The problem was confirmed by a dealer as a failure of the Battery Energy Control Module, which has been happening to this car with numerous other owners, according to the Volt owner website.

Action Required Shift to Park message comes up on the dash after starting the vehicle & shifting into gear out of Park. The message goes away when shifted back into Park, but the vehicle doesn't respond when shifted into gear. Reverse, Neutral, Drive, Low - none will engage. I had to repeat the process of starting the vehicle 28 times before it would operate as it should. Start Vehicle to View Application message comes up when in Park & trying to shut the vehicle off & will not power down until the driver door is opened. I worried that I'd be stranded if this continued to happen & took the vehicle to Brad Deery Motors in Maquoketa, IA for repair on 4/14/22. I paid $736.71 & the invoice states: 106128 shift to park, diag, intermittent open in the shift park solenoid, replaced shift park solenoid and jumper harness, tested working properly. I brought the vehicle home & had the same messages appear on 4/19/22. I have since read a forum on the Volt & understand that this has been a common issue & found a service bulletin: 19-NA-206, but wondering if there is an actual recall. I plan to contact GM regarding this issue.

There is a -€œShift to park-€ message on the driver information screen when attempting to shut off vehicle. I don-€™t know if the vehicle is still in gear and will move (forward or back) when I think it is in Park. I have not had it in for inspection/repair yet, as it is a recent occurrence that is becoming increasingly frequent. This started happening around 11/15/2021.

My 2016 Chevy Volt has an issue where the is an intermittent shift to park message displayed while the vehicle in in park. This issue has been identified as a widespread issue and Chevrolet has published a Service Bulletin (NHTSA Technical Service Bulletin 19-NA-206). The most recent version is Version 6 that was published in December 2020. The dealership is refusing to perform repairs that are clearly under warranty. The service bulletin specifically says it is covered under the warranty.

Vehicle Shifter does not correctly register the vehicle is in park. Does not allow the vehicle to be turned off. This is a common issue experienced by Gen2 Volt owners and well known by GM Service Tech and GM has not yet issued a recall. There is a potential safety issue if someone believes the vehicle is parked and exits the vehcile and the car is left running. Potential Driver Confusion on the park status could lead to the vehicle continuing to run or being put back in gear. GM needs to issue a recall for Gen2 Volts - 2016 and on.

When I put the car in park and try to turn it off, I frequently get an error on the gauge display that says "action required, shift to park." This is very frustrating. When this error happens, I'm unable to power off the car or lock the doors. I turn the car back on, jiggle the shifter or move it into drive and back to park, and then try turning the car off again. Sometimes I have to go through this process 5 or more times before the car will power down. This error happens about half the time that I use my car, which makes it a daily problem. I bought the car used in Oct 2019, and the previous owner also had the problem but I don't know when it started for him.

An error appears "shift to park" when parking. The car does not recognize that it is shifted to park thus it continues to run. A running vehicle that cannot be turned off and can run on gas is a considerable hazard. The GM forum for Volts contains many such messages for 2016 Volts and a problem with the same system error led to a recall in 2017 Volts. The problem is occurring with increasing frequency in this car, starting a few months ago.

When parking the car there's a chance for the error "shift to park" to occur when trying to turn off the car, . this is due to a defective switch that wears out within the shifter assembly. The error starts to become more and more common as time go on. It is too easy to accidentally leave the car "on" when shifting the car to park and stepping out of the car and using the push to stop. The only known workaround is to flick the shifter button until the car registers that the car is now shifted to park. This is a recurring and well known issue in the Chevy Volt community. It's predicted that all 2016+ Chevy Volts will eventually develop this issue due to the defective design of this switch. I have another Volt in the family that's already had the shifter replaced because of this same issue.

After 100K miles right when my warranty ends, I'm getting the shift to park error message, constantly having to power up the vehicle off and on is annoying. I I feel like the car is breaking more. Very unsafe.

- Oxnard, CA, USA

After putting the shift lever in park, then powering the vehicle off the dashboard would advise to shift the vehicle in park. Could not lock vehicle, lights would remain on. This could be worked around by pressing the shifter knob a few times to clear the message. Brought vehicle in for regular service, was advised there was a short in the wiring harness related to the shifter knob. Harness was replaced, issue has not repeated. It has been noted online that this is a common issue with generation 2 Volts, I wanted to add my vehicle to the list of those affected.

When putting shifter to park, the action required messages is shown as: 'shift to park' issue. The car will effectively not turn off. You'll be unable to lock the car and the lights will stay on for a few minutes. Worse yet, it is intermittent although it generally gets worse over time.

- San Marcos, CA, USA

The vehicle does not recognize it has been shifted into park, which does not allow the vehicle to be turned off. Dash display states 'action required, shift to park'. this happens consistently and is a known issue by Chevrolet. Yet they have not issued any recall. It is known as the 'shift to park' issue. There is no work-around for the issue other than shifting back and forth into gears, sometimes hundreds of times, before the error clears. For example: My wife took my daughter to an emergency room and could not get the vehicle to turn off. She tried to clear the error a few times before having to leave the vehicle running in the parking lot.

- Pittsburg, CA, USA

Unable to turn off car when shifter is physically shift to park, but dash warning has a "shift to park" warning. Back in Dec 26 I bought the car in for the same issue and the shifter cable was replaced. But shift to park warning returned a few months later. It is a matter of time before this issue will return.

- Kent, WA, USA

Shift to park issue. When trying to turn off the car you put in park and press on/off button. Car says you need to shift into park even though you have shifted into park and is so indicated on the dash. You have to shift the shifter and turn on and off until finally turns off. Crazy and a know problem. Dangerous and need a recall.

- Cornish, NH, USA

Car says "shift to park" at random, when car is already in park. Prevents you from powering off the vehicle, and have to sometimes wiggle the shifter before it will detect it is actually in park.
