Owner reports
Selected complaints filed with NHTSA by 2012 Chevrolet Volt owners, lightly cleaned up (personal details are redacted by NHTSA).
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.
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.
In September 2019, the Office of Defects Investigation (ODI) opened [redacted] 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 [redacted] 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.
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.
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.
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.
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.
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.
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.
The "service airbag" light starting coming on. I took the car to the dealership and they said that the harness in the driver's seat has a bad sensor or plug and cannot be replaced because GM no longer makes this part. They suggested that I might try to find a replacement seat in a junkyard. This means I have car that is less than 10 years old with a driver's side airbag that may or may not deploy in an accident. The dealership does not have a solution.
