2017 CHEVROLET VOLT Complaints

BECM (Battery Control Module part # (24296900)) on my 2017 Chevrolet Volt failed. When the failure occurred the instrument display showed a “Propulsion Reduced” warning. At the same time the engine started (the traction battery was fully charged at the time) and the check engine light came on. I subsequently received an email from General Motors that they had detected a lithium ion battery problem with the car and to have it serviced within 7 days. The GM dealer subsequently diagnosed the issue as a failure of the BECM module. Although an online search of this issue shows that there have been hundreds of failures of this module there are no replacement parts currently available. The car has been sitting at the dealer for several weeks with no estimate of when a replacement part will be available. The dealer has recommended not driving the car until it is repaired. I was able to drive it to the dealer on electrical power after the failure occurred.

I received a 'Reduced Propulsion' message along with a check engine light and that progressed to a 'Engine not Detected" message and stranded along the interstate in a dangerous situation. Had it towed to a dealership which had a technician which could work on a volt - he replaced the Engine Control Module fuse which "fixed" the car for about 15 miles and then the 'Reduced Propulsion' error with the Check Engine light appeared. Technician said something must be shorting out the fuse. Dangerous situation.

Drive power reduced, Shift to Park, BECM faulty part 24296900 not covered by warranty. Car cannot be shut down

Shift to park message and will not allow car to be turned off. This problem also occurred ~2 years ago and the part was replaced by Chevrolet under warranty. This seems to be a serial defect

The check engine light came on followed by a loss in propulsion power of the engine. During freeway driving, a sudden loss of power posed a significant risk to both driver and other drivers on the road as the resulting sudden loss of acceleration forced other drivers to swerve around the vehicle to avoid hitting the car. The problem was reproduced when the engine came back on after 2 attempted repairs. I am very scared and concerned with my life/safety.

I bought the car in 2020. It had intermittent problems with the car registering “shift to park” when the car was in park. This would not allow the car to be started, leaving me stranded. The intermittent problem has become much more frequent now. Yesterday and today 16 Dec 2021, the car is not ever registering that the vehicle is in park. The transmission display shows I am in “P” (park), but the display keeps saying “shift to park” and the car won’t start.

The contact owns a 2017 Chevrolet Volt. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The contact mentioned that the electrical hybrid battery failure warning error was illuminated, and the check engine warning light was also illuminated. The vehicle was able to start after multiple attempts to switch over to gasoline mode. The vehicle was taken to the dealer where it was diagnosed that the battery energy control module needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 46,000.

The vehicle’s service airbag warning light is illuminated. The dealership diagnostic indicates that the passenger seat sensor needs to be replaced. Based on my research, this was also an issue with the Volt’s 1st Gen models.

When placing my car into Park and then powering it off I get an error message telling me to shift to park to shut vehicle off even though it is in park. Problem is two fold: I cant turn the car off and the result is a battery that runs dead. Very frustrating and if the car isnt off it could accidentally be put into gear by a child.

The vehicle often will not turn off after pressing the power button, even though it is in the Park position the vehicle stays on with the console message “Shift to Park” displayed. Normally releasing and the re-engaging the foot brake and toggling the shifter lock resolves the problem, but today (Nov 22, 2021) the vehicle did not recognize that the vehicle was in Park when in a city parking lot after approximately 10 minutes of attempting to turn off the vehicle. If the vehicle does not recognize that the shifter is in park and does not turn off, the battery may drain, and if one needs to leave the vehicle, the operator cannot be sure the vehicle will remain in position. No warning lights appear for the vehicle on turning on the vehicle.
