Chevrolet Volt

While driving at highway speeds over 100 miles away from home with my child in the vehicle, the car experienced a sudden, catastrophic loss of propulsion power and entered 'Propulsion Power Reduced' mode, dropping vehicle speed immediately and creating an extreme hazard with high-speed highway traffic. A full computer scan revealed active diagnostic codes U2603 through U2624, confirming an internal hardware communication failure of the Battery Energy Control Module (BECM). This matches GM…

I purchased the above-listed 2016 Chevrolet Volt through Carvana, relying on the contractual promise that the BECM was covered under Special Coverage N232432680 for up to 15yrs or 150k miles. The vehicle has suffered persistent, severe mechanical and electrical issues resulting in a prolonged loss of use: 1. Initial Breakdown and Delivery: The vehicle originally had a Reduced Propulsion Power Alert on Monday [XXX] around 8pm and nearly caused me to be rear ended on a major road due to…

Received reduced propulsion message, with no engine detected. Car slowed to a near stop while driving on the Interstate highway. Very dangerous to have that suddenly happen. Message popped up randomly with no prior warning.

I was not going to put in a complaint about this failure but after learning about GM creating a special extended warranty program for this issue, I felt it should be addressed and treated as a recall. The battery energy control module (BECM) failed on my 2017 Chevrolet Volt at exactly 170,000 miles in December of 2024, leaving me in a dangerous position on the roadway and almost causing me to be rear ended due to losing the ability to accelerate. I had no choice but to have the vehicle towed…

My 2016 Chevy Volt started experiencing the Propulsion Power is Reduced issues associated with a faulty BCEM unit. I brought my vehicle in for service at a Chevy dealer and they confirmed that the BCEM needed to be replaced. This is a known issue resulting in special coverage under N232432680. Chevy is not honoring the special coverage for my vehicle despite my vehicle being less that 15 years old and having fewer than 150,000 miles. According to the service manager after talking to someone…

Rear view camera display experiences intermittent failures. The display only occasionally works when the car is placed in reverse. This has led to nearly impacting one or more pedestrians when the car is driven in reverse.

BECM failure. My car is available for inspection upon request. This car has unexpectedly stopped adequately accelerating all of a sudden while on the road! This problems has been confirmed by the dealership. The manufacturer has not inspected it. Not much warning. I found out SOME not ALL chevrolet volt 2017 users got their BECM replaced without cost because it is a WELL KNOWN ISSUE with the car. Chevrolet did not provide extended warranty for all chevrolet volt users even though it is an issue…

I was driving my 2018 Chevy Volt at about 30 mph on EV mode. The battery was at 50%, the car was performing normally. Then the battery jumped to 100%, the check engine light came on, and the vehicle lost power. I was in rush hour traffic and unable to get the vehicle to go faster than 5-10 mph. I switched to normal mode to engage the gasoline engine, hoping this would help but it did not. The gas engine RPM fluctuated wildly and did not restore the ability to accelerate the vehicle. I…

Fully charged. Goes from electric to generator/gas propulsion and abruptly slowes about 1/2 speed. Very dangerous.
