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.

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.

The contact owns a 2012 Chevrolet Volt. The contact stated while operating the vehicle, the front passenger’s side air bag warning light remained illuminated. The vehicle was taken to the local dealer who determined that the front passenger’s side air bag Passenger Sensor System was faulty and needed to be replaced. The vehicle was not repaired. The contact was informed that the part to repair the vehicle had been discontinued and no repair was available. The manufacturer was contacted and confirmed that the part was discontinued. The failure mileage was 100,000.

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.

The contact owns a 2012 Chevrolet Volt. The contact stated while driving approximately 50-60 MPH, the Engine Failure, Mountain Mode Not Available, Battery at Zero Percent, Propulsion Power Reduced, and High Voltage messages were displayed. The check engine warning light illuminated. The vehicle then inadvertently decelerated to 30-40 MPH. The contact pulled over to the side of the roadway and turned off the vehicle. After several attempts, the vehicle was able to restart. The vehicle was taken to the dealer, where it was diagnosed that the high-voltage battery pack needed to be replaced. The vehicle was not repaired. Additionally, the contact stated that the vehicle failed to pass the yearly vehicle inspection. The dealer loaded sample data into the computer and then drove the vehicle for 50 miles before the vehicle passed inspection. The manufacturer was not made aware of the failure. The contact related the failure to NHTSA Action Number: PE23022 (Electrical System). The failure mileage was approximately 100,000.

The contact owns a 2012 Chevrolet Volt. The contact stated while driving at an undisclosed speed and attempting to slow down, the brake pedal required an abnormal amount of pressure to slow the vehicle. The ABS warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the brake pressure modulator valve. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 13V271000 (Electronic Stability Control, Service Brakes) however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 120,000.

The contact owns a 2012 Chevrolet Volt. The contact stated while driving at various speeds, the "Service Air Bag" warning light intermittently illuminated. The contact notified a dealer about the failure and was provided a diagnostic fee. The manufacturer was also notified of the failure and the contact was provided the same information. Upon investigation, the contact discovered NHTSA Action Number: PE19013 which was linked to the failure. The NHTSA investigation was later closed. The vehicle was not diagnosed or repaired. The failure mileage was approximately 127,000.

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.

A false code was given indicating the coolant level was low on the batteries. This was a know compute glitch problem which required an update costing me 400 dollars.

Defective front passenger seat occupancy sensor. The defective sensor makes the passenger airbag unusable, sacrificing passenger safety.

The 2012 Chevy Volt Passenger Airbag Sensor was an issue that the NHTSA investigated. It will cause the passenger side airbags not to deploy in a crash. I can reproduce the airbag warning light by pressing on the passenger seat. It has also been confirmed by an independent service center. There is supposed to be a reduced cost replacement program (according to the NHTSA) but both dealers and the Chevrolet Support Center do not seem to know about it)

2012 CHEVROLET VOLT, THE VEHICLE HAS BEEN LOSING POWER FOR PROPULSION ON THE HIGHWAY/ROADS AT ALL SPEEDS. SHUTTING OFF. ELECTRIC CHARGE IS SUPPOSED TO SWITCH TO THE GASOLINE MOTOR WHEN IT IS LOW, BUT IT DOES NOT, AND VICE VERSA. IT SHOWS HYBRID BATTERY MANAGEMENT HAS A LOSS OF PROPULSION WITH A MESSAGE OF LOW PROPULSION POWER. THE ORIGINAL PROBLEM WAS NOT FIXED WITH A RECALL A FEW YEARS BACK BECAUSE THE SAME PROBLEM IS SHOWING UP. NOW, CHEVY DOES NOT HAVE THIS VIN BEING RECALLED. BUT WORSE, THE CONDITIONS IN THE SOFTWARE ARE CAUSING A POWERTRAIN FAILURE WHILE DRIVING. PLEASE HELP. I AM PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The passenger seat occupancy sensor is malfunctioning and needs replaced.

Seat sensor for passenger air bag is not working. It picks up a passenger and turns on air bag then turns it off. Then back on then off. Getting service airbag light. I see this was investigated by NHTSA and chevy was supposed to build a replacement program for 12-13 volts but when I call chevy they see no such program even though it is reported as a known consumer concern and was part of agreement when closing NHTSA investigation as per articles on this from journalist.

Airbag light is on due to faulty passenger seat sensor that is a known defect by manufacturer. Your investigation was closed with the note that "GM created a program to replace the passenger sensing systems in 2012 and 2013 model year Chevy Volt vehicles". I am trying to get them to fix the issue, but they say there is no program for this repair. And the repair consists of replacing full passenger seat for over $1000. It looks like GM is misleading NHTSA that they have a program to correct the problem.

Driver’s display completely dark. I can’t see speed, gas remaining, charge remaining, turn signals, gear, warnings if tire pressure is low, etc. Upon turning the car off and back on, the display lights back for an couple of minutes until it goes dark again. There was no warning before it happened for the first time a couple of days ago. The car is extremely unsafe and not drivable as I have no idea how fast I’m going, if I’m about to run out of gas, etc. Luckily, the screen went dark when my 16-year-old daughter was driving in our neighborhood. This should definitely be a recall issue.

Blank (dark) main screen display for speedometer, fuel, etc. Fuse not blown. the vehicle is unsafe to drive. One can run out of electrical power and or gas and not know, stop on the highway and be in harms way. no turn signals, no speed indication at all, nothing. this is recall worthy! and needs to be addressed by chevy.

I'm constantly receiving a "Propulsion Power Loss" notification on my car. I have brought the car in to a Chevrolet dealer and they refuse to fix it unless I start paying out of pocket costs because the ticket is "closed". This has been going on for about a year since I purchased the car last November and I'm terrified to drive this car since it literally looses power.

In mid 2020 I began to get an intermittent warning of a problem with the passenger side, front seat occupant sensor. The problem has become much more frequent. The GM service department was familiar with the problem in 2020, but said there was no recall. If the passenger moves around the sensor will activate or deactivate. I assume that the airbag would not dependably deploy in an accident. Today I discovered a discussion of this problem in the GM-Volt Forum. The forum mentions the same problem with other GM models. This is obviously a safety and manufacturing issue. Repairs are quoted in the $800 to $1,000+ range with no guarantee the problem won't reoccur.

Airbag Service Light comes on for unknown reason. This appears to be a very common problem amongst Chevy Volt owners (2012-2013). Why no recall for this serious safety issue?

The contact owns a 2012 Chevrolet Volt. The contact stated that while his son was driving 55 MPH, the vehicle lost motive power. The vehicle was taken to the dealer and diagnosed with engine software failure. The contact was informed that the engine software needed to be updated. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 113,000.

The contact owns a 2012 Chevrolet Volt. The contact stated while driving 40 MPH, the brake pedal was applied however, the vehicle failed to stop. The contact was able to maneuver the vehicle and coast to a parking lot. There were no warning lights illuminated. The vehicle was towed to the local dealer to be diagnosed. The contact was informed that the brake module modulator needed to be replaced. The contact stated that the failure was related to NHTSA Campaign Number 13V271000: (Electronic Stability Control, Service Brakes). The manufacturer was notified of the failure however, no further assistance was provided. The failure mileage was approximate 84,682. Vehicle exhibited the issues listed in the recall but your VIN is not included.

My 2012 Chevrolet Volt has had a failure with the passenger air bag presence sensor. As a result, the passenger air bag indicator has been going on and off intermittently while someone is riding in the passenger seat. This has been happening since 2017. It has gotten worse over time and is usually off when it should be on. My passengers no longer feel safe. This is a failure that could result in the passenger’s death if the air bag fails to deploy in a crash. The repair cost from the dealer is also unreasonably expensive at over $1,000. The part alone costs $400 and requires proprietary dealer programming equipment for installation. A critical safety failure like this should be immediately recalled and fixed at no cost to the owner. This is not an isolated incident and has been widely reported across the internet.

We began receiving the intermittent warning message "Service Airbag" on our 2012 Chevy Volt at around 65,000 miles, and are continuing to receive it at 69,000 miles. Research reveals that other Volt owners have encountered the same problem. Cost of repair: $1,000. It appears to be a manufacturer sensor defect that requires a recall.

While traveling slowly (about 25mph) on an uphill grade, my Volt suddenly, with no warning messages or other alerts to me, lost propulsion, power brakes and power steering. This car is extremely hard to steer and to brake without the power assists, so I really had to wrestle with the wheel to avoid losing control of the car, and I really had to jam on the brake pedal to get it to a stop, even though I was moving slowly and had a gravity assist from the uphill slope. It seems to me an event such as I experienced could be catastrophic if it occurred at high speed, and / or on a steep downhill slope or a street with a lot of traffic. Incidentally, when this happened I had just turned onto a side road from a highway with lots of traffic moving at 60-80 miles an hour on a slope so steep that in spite of numerous warning signs, accidents, including fatal accidents, occur regularly on this section of the highway due to drivers failing to apply their brakes hard enough or early enough to keep the car on the road. As a result I felt like I had barely escaped with my life, only as a result of a sudden whim that entered my head to leave the highway for the scenic side road. It may also be relevant that the incident occurred directly after I picked up the car from the Chevy dealer following repair for another incident where I lost propulsion, power brakes, and power steering - the difference being that the car was stationary during the previous incident. The photo shows the electrical connections that the dealer ultimately determined were responsible for the second (Oct. 20) incident, and maybe the first as well. These terminals are enclosed, and not visible to the car owner, even with the hood lifted. Checking the terminals is not part of any maintenance recommended in the owner's handbook, nor apparently in the standard service procedures, even when a car comes in with symptoms that could be caused by a loose connection, even after replacing the 12V battery, as they did.
