2012 Chevrolet Volt

Defect. General Motors LLC (GM) is recalling certain model year 2011-2013 Volt vehicles manufactured August 25, 2010, to June 26, 2013. If the driver exits the vehicle without turning off the electrical system, the battery may drain low enough that the gasoline engine will automatically start itself to recharge the electric battery.

Risk. If the engine runs for an extended period of time in an enclosed space, there may be a build up of carbon monoxide, increasing the risk of personal injury.

Remedy. GM will notify owners, and dealers will update the engine management software to limit the time that the stationary vehicle can be left in the ON position, free of charge. The recall began April 15, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 14617.

Defect. General Motors (GM) is recalling certain model year 2012 Chevrolet Volt vehicles manufactured March 1, 2012, through April 17, 2012. Due to a brake pressure modulator valve problem, the vehicles do not relieve brake pressure from the front brakes during an anti-lock brake system (ABS), electronic stability control (ESC), or traction control event. One or both front brakes may lock up and not release. Thus, these vehicles fail to conform to Federal Motor Vehicle Safety Standards (FMVSS) No. 126, "Electronic Stability Control Systems"' and No. 135, "Light Vehicle Brake Systems."

Risk. If the brakes lock up it could cause a loss of steering control and/or a lengthened distance needed to stop the vehicle, increasing the risk of a crash.

Remedy. General Motors will notify owners, and dealers will install a new brake pressure modulator valve free of charge. The recall is expected to begin July 12, 2013. Owners may contact Chevrolet at 1-866-694-6546. GM's recall number is 13184.

Airbag sensor failure in seat.

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.

Vehicle propolusion reduced and engine not available messages were suddenly showing. Check engine light turned on. Suddenly Stalled/stopped in the middle of highway. Safety concerns

In September 2019, the Office of Defects Investigation (ODI) opened [XXX] to assess the malfunction of the Passenger Sensing System (PSS) in the 2012-2013 Chevrolet Volt vehicles. Due to that malfunction, the air bag system malfunction indicator light is activated. This could cause the passenger airbag to be suppressed in a crash. In July 2021, the ODI closed [XXX] after GM instituted a cost reduction program for the repair/replacement of the PSS in the subject vehicles. In July 2023, I took my 2012 Volt to a local dealer to correct this problem, only to learn that the necessary replacement part has been DISCONTINUED by GM and is no longer available. That is, frankly, unconscionable. I am requesting that ODI reopen the investigation and take further action to compel GM to make this repair available.

This issue has been reported extensively: NHTSA PE19013. The passenger seat sensor has failed leading to the airbag turning on and off rapidly while driving. This is available for inspection upon request. I worry about the safety of occupants in the car. If the airbag is turned off despite a passenger sitting in the seat that is a problem. The price of repair at a dealer is very high considering that this is a very clear quality control issue by GM that has been acknowledged by both GM and NHTSA. This warning light has turned on before and then went away for a long time. Now it has returned and after some research it is clearly an issue that many other 2012-2013 volt owners have experienced.

Airbag sensor harness underneath the passenger seat comes disconnected from moving the seat back and forth causing a warning on the dash. GM has a TSB about this and should rewire the harness for free. The passenger presence module is undetected when the seat moves forward but is detected when moved to its full rearward position.
