2012 Chevrolet Volt problems

“The contact owns a 2012 Chevrolet Volt. The contact stated that while the vehicle was parked and occupied, the contact attempted to start the vehicle; however, the instrument panel displayed a blank screen. An independent mechanic was contacted. The vehicle was taken to an independent mechanic to be diagnosed, and the contact was informed that the instrument cluster needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 132,000.”

“passenger presence detection system is malfunctioning, and causing a "service airbag" warning. This is a huge safety issue that could be detrimental or deathly in the event of an accident. This is a common issue among generation 1 volt owners, and should be considered for a recall or warranty coverage. The passenger presence detection system parts are discontinued, and even if I found the part the dealership cannot confirm for the pricey repair, that the airbag / sensor will not simply malfunction again -- which makes this a persistent safety concern and huge owner inconvenience to say the least.”

“Message on dash "Service High Voltage charging system" . Code cleared by inexperienced mechanic. Stalled on the side of the road with "Engine not available" , "Low propulsion" . My local Chevy dealership confirmed a high volt battery leak its now at risk for catching on fire”

“Vehicle over-revs in cold weather. Engine runs excessively fast (4250 RPM) at highway speeds and around 3000 RPM when just sitting. Often times if I pull over and restart the car it will correct itself. This results in MPG as low as 22. The internet is full of examples of people with the exact same problem. I have seen no examples of the problem being solved. The engine will operate correctly in warmer weather (above 50° F). I believe it is related to an aging propulsion battery and could be solved by improved programing to accommodate the battery state.”

“Grandson was driving and went to brake to make a turn and the engine not available light came on and he had no brakes. He was unable to slow and take the turn and hit a truck in the front driver quarter panel which resulted in the car being a total loss.”

“7/6/2024 Was driving 45 mph on a busy road (running only on the gas engine of this plug-in hybrid). Propulsion Power Reduced message showed near the speedometer. My speed was immediately decreased. The check engine light also came on. Despite pressing the gas pedal, the speed could not be maintained and I had to pull off quickly before causing an accident. Luckily, no accident occurred but I fear would could have happened if I wasn't in the right place to pull over quickly. After getting the car towed to a Chevy dealership, they diagnosed the problem as being with the hybrid battery - it needs to be replaced. I don't understand why I had a full tank of gas, was running on gas, and that a bad EV battery would cause ALL propulsion to stop so quickly.”
