NHTSA investigations into the 2012 Chevrolet Volt

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

The HV battery is lithium-ion based technology that has a nominal full charge of 390 VDC, a 16 kWh capacity, and a control system that incorporates liquid (antifreeze) cooling and various electronic devices (control modules, sensors, wiring, etc) to monitor and manage the HV battery. The HV battery, portions of the cooling system, and the control system are contained within a common enclosure.During an NCAP oblique side pole imp...

Recalls on the 2012 Chevrolet Volt

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2015104 2,194 units in Canada

Engine

On certain vehicles, if a driver exits the vehicle and were to inadvertently leave the vehicle "ON", after a period of time the vehicle's battery would drain and the vehicle's gasoline engine would begin to run. If the gasoline engine were to run for long periods of time when the vehicle is parked in an enclosed area, such as a garage, there is a risk of carbon monoxide build-up, which could result in asphyxiation or carbon monoxide poisoning. Correction: Dealers will update vehicle software to limit the time that an idle vehicle can be left in the "ON" position.

Recall 2013460 76 units in Canada

Accessories

On certain vehicles, material used in the construction of the windshield sunshade, sold as an optional accessory, may not meet the requirements of the Canada Motor Vehicle Safety Standards (CMVSS) 302 - Flammability of Interior Materials. The sunshade's inner core material could burn faster than allowable by the standard. Note: The exterior material, exposed in normal use, meets the requirements of the standard. Correction: A production change was made to add a flame resistant coating to the interior corrugated plastic layer to remedy this non-compliance condition. No corrective recall action is required as the technical non-compliance condition is deemed to be non-safety related.

Recall 2011412 39 units in Canada

Lights And Instruments

Certain vehicles fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 108 - Lighting System and Retroreflective Devices, as well as CMVSS 114 - Theft Protection and Rollaway Prevention. These vehicles were inadvertently programmed with incorrect Daytime Running Lamp (DRL) and theft protection calibration files during vehicle assembly. This could allow the driver to switch off the DRL system while the vehicle is underway. It could also allow non-dealership personnel to reprogram a replacement ignition key. A loss of DRL illumination could render the vehicle less visible to other motorists and to pedestrians during daylight hours, possibly resulting in a crash causing property damage and/or personal injury. Correction: Dealers will reprogram the Body Control Module.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

SEATS

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.

ENGINE

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.

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.

POWER TRAIN

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.

NHTSA complaint #11590578 — an unverified report by a vehicle owner.

Bakersfield, CA

STRUCTURE:BODY

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.

AIR BAGS

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.
