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

Car will randomly accelerate when not on gas pedal and/or a delay in brakes working. Has happened on more than one occasion.

The contact owns a 2012 Chevrolet Volt. The contact stated that the vehicle failed to start, and the lights inside and outside of the vehicle failed to illuminate. The vehicle was jump-started. The failure reoccurred while attempting to restart the vehicle, and the contact was unable to drive the vehicle. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was unknown.

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.

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.

THE CONTACT OWNS A 2012 CHEVROLET VOLT. WHILE DRIVING AT THE SPEED OF 70MPH THE INSTRUMENT PANEL BECAME INOPERABLE WITHOUT WARNING. AS A RESULT, THE CONTACT WAS UNABLE TO DETERMINE THE SPEED OF THE VEHICLE, ALONG WITH THE AMOUNT OF FUEL THAT WAS INSIDE THE VEHICLE OR ANY WARNING LAMPS. THE INCIDENT HAPPENED WITH THE VEHICLE HAVING 99,835 MILES.

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.

This is a report on a previous safety recall that has failed to fix the problem. The recall is GM Program # N172130462 for sudden-onset reduced propulsion. The recall repair was performed on this vehicle at 91,064 miles. However, since the recall, a reduced propulsion condition has recurred multiple times. Subsequent to the most recent episode, the vehicle has been in the dealer's repair shop for 5.5 months. The dealer technician affirms it is a software problem, but is unable to figure out how to repair it, even with assistance of a General Motors field engineer. The dealer technician told me that the GM field engineer knows of other cars with the same problem.

Coolant leaking and damage to Drive Motor Battery Coolant Radiator due to the design of the vehicle that allows for rocks and debris large enough to damage radiator through. There is a service bulletin (13-06-02-001A) for this issue. When the radiator is damaged, the driver will suddenly receive a check engine light, reduce propulsion notice, and engine not available message. The car will suddenly stall and this cause a major safety concern especially on highways at high speed. However no active recalls, even though this is a common reoccuring problem amongst first generation Volts.
