*Median odometer reading when the problem happened, where owners gave one. One complaint can name several problem areas.
Fuel/propulsion system
The vehicle experienced a catastrophic charging system failure. When connected to the wall charger, the charge port becomes hot to the touch within seconds. The charger connector has now cracked from heat stress, and the wall charger itself previously melted due to electrical backfeed from the vehicle. The vehicle refuses to charge at all. This appears to be a thermal event and fire-risk safety defect involving the onboard charger, wiring harness, or battery management system. Insurance refused coverage due to the nature of the electrical failure. The vehicle is unsafe to charge or operate.
Jul 4, 2026Service brakes
A "service brakes" warning came up when I was parked in a parking lot and immediately afterwards the brakes stopped working when I was reversing in the parking lot and I almost backed up into another car. I had my car towed to Paradise Chevrolet and they diagnosed the problem as a faulty "brake pressure modulator valve" (BPMV) that needs to be replaced. I saw that there is a recall for the 2012 Chevy Volt for the same issue, faulty BPMV.

My 2015 Chevy Volt has been experiencing ongoing mechanical and electrical issues, including random power loss, reduced propulsion warnings, and sudden vehicle shutdowns with no prior indication. These problems pose a serious safety concern, as the car can lose power unexpectedly while driving. Despite these issues, GM has refused to service the vehicle or unlock necessary components because they no longer manufacture or support the required parts. As a result, I am left with an unsafe and unreliable vehicle with no available remedy from the manufacturer. This is forcing me to trade in the vehicle at a loss

On all (4) tires, there is cracking in the sidewalls in a line about 2 inches above the tire bead around each tire. Approximately 19K miles on these tires. Manufacture and supplier/seller (Priority Tire) both sent multiple photos of issue, tread depth, etc. and then denied any warranty on the tires due to 'Improper Usage' (reply below) I asked the supplier/seller and the manufacture what that means and no reply. Tires are consistently rotated by myself and tire pressures consistently maintained. I am [XXX] and don't race or off road my Volt. This could be a potential safety issue if one or more tires were to fail unexpectedly. Please see photos and thank you for your help. Hello, We are…

The car has not been able to charge since April of last year. I have taken it to the dealer to diagnose but they want to charge $200 per hour to diagnose. They already suggested that the charge receptacle should be replaced. I purchased the part and replaced it myself. I have tried asking if it could be the BECM like with other model years and they said they could only determine that after testing and replacing parts. The P1EE6 error code suggests that the BECM might need to be replaced and/or reprogrammed. There have been several times that I have experienced a loss of propulsion error while driving. I know there is a safety bulletin for the 2016-2019 models year that I think should apply…

I will be driving on the road and randomly my vehicle will give me a loss of propulsion warning. This has happened many times on the highway where Iâve lost acceleration power quickly and have almost been involved in a futile accident as a result. My vehicle also randomly switches from electric to gas sometimes causing my car to jolt

This car is connected to Bouncie a device that detects when a car turns on and off, the speed, if break or acceletor are stepped on forcefully and any trips. Recently the device is detecting the engine is turned off but the car is showing no signs of struggling and its in full motion. This is new, I've tested the device in another car for two weeks hoping it was the device but I had no issues on the other vehicle. The images is just one of several occasions. The image shows green dot where car starts and red where car is turned off. However, I never turned off my car at the Demaree Rd that day. I feel like the car is losing power and starts back up while in motion.
