2014 Chevrolet Volt electrical system problems

“I was slowly maneuvering my car into my garage when the vehicle suddenly and unexpectedly surged forward, despite only lightly tapping the brake and not touching the accelerator. The car had been displaying the warning, “Propulsion Power is Reduced” and was not holding an electric charge in the days before the incident. No malfunction indicator lamp ever turned on. Per the owner’s manual, the vehicle did not need to be serviced because the malfunction indicator light never came on at the same time as the propulsion power reduced message. This led me to believe the vehicle was safe to drive. The unexpected surge caused the car to strike and cause considerable damage to the garage wall. Fortunately there was no one in the garage at the time and I, myself, was not injured. My car was deemed a total loss by the insurance company.”

“The contact son owns a 2014 Chevrolet Volt. The contact's daughter stated that while driving 40 MPH, the vehicle loss motive power without warning and the vehicle stalled. The contact was able to pull over to the side of the road. The vehicle was towed to an independent mechanic and was diagnosed with battery failure. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the time frame for a free battery replacement had expired. The vehicle was towed to the residence and had not been driven since the failure. The failure mileage was unknown.”

“Loss of propulsion. Vehicle will not start/move. If vehicle does turn on , it will not turn off. Vehicle has been having reduced propulsion issues for multiple years (taken to dealer many times) that dealership has refused to do a HV battery capacity test while under warranty, even after leaving with them for multiple months they claimed they could not replicate error. On day of pickup error presented itself and I showed service advisor and left vehicle for additional testing. Dealer provided explanation of reduced propulsion when in mountain mode as cause even though vehicle was not in mountain mode when error occurred. Dealer performed customer satisfaction GM Program # N172130462 update 11/2021 on HV system that stopped propulsion issues (mainly battery capacity concerns) until vehicle was out of warranty. Now vehicle will not turn on/move even though HV battery completely charged. Vehicle is essentially bricked at this point. Will be taking back to dealer 12/30/2024”

“I bought my car and I had no idea about a known issue that this car has. Unsuspecting and trusting, I noticed my car had a reduced propulsion and it would like lose power and just slowly jerk and then really drastically reduce speed without anyway to fix it and on the freeway I got scared as I have never in my life has this happen in any car. So it happen a couple more times and I took a picture of it and took it to the dealership where I purchased it. They told me they couldn’t do l as they can’t repeat the issue. Well that only usually happens when I’m driving but now it’s more. The propulsion thing loses power and I as a driver going up a hill or anywhere now will lose speed and it’s dangerous, I feel like I may not make it home and I took it to the dealership many times and they told me there’s no issue. I took it again recently now that I’m out of warranty because it also had some high voltage issue and a sensor coolant issue that misreads. I like the car but very unhappy about dealership and manu not fixing this issue that every volt owner I talk to has, read about. I lose power, my car randomly heads up when it’s been cold all night and not driven now I…”

“Vehicle stopped when changing from battery power to gasoline. Unable to drive. Not charging the Lithium battery therefore, I experienced 3 similar incidents with this vehicle.

This time same issue when the main battery was depleted the vehicle stalled. I had to towed to my home where is still sitting. Not operational.”
