I am getting an airbag warning light caused by a faulty passenger presence module. If I have a passenger riding with me, the warning light will go on and off sometimes caused by hitting bumps in the road. When the light is on though, it says the passenger airbag is off which is a very big safety concern. The vehicle has never been in a wreck or had any liquid spilled on the seat.

The airbag sensor stopped working causing the passenger airbag to be turned off.

Continuously receive a "service airbag system" warning. Began happening for no apparent reason. Warning stays on all the time (as soon as vehicle is started). Dealership investigated and determined that the passenger side seat sensor for the airbag must be replaced, at a high cost (~$800). Without this repair, it is possible that the passenger side air bag may not deploy in the event of an accident (sensor does not indicate that someone is seated on passenger side, so only driver's side may deploy).

(Chevy Volt 2013) a warning message "service airbags" intermittently shows. The car has not been involved in accidents. It appears to be a very common issues among Chevy Volt owners (including 2 people in my family who own the same car model) the warning shows while driving and disappears after a few seconds.

Airbag weight sensor issues on passenger side

- Garden Grove, CA, USA

The check airbag indicator light and the passenger airbag go on and off repeatedly even if a passenger is in the seat. The passenger presence system has failed at 70,000 miles. It happens whenever the vehicle is being driven making it unsafe to have a passenger in the front seat. I have read several GM and Volt blogs and this seems to be a common problem with 2012 and 2013 Volt.

Component designed to detect passenger sitting on the passenger seat has failed causing the airbag to remain off. Dealer says the passenger presence detection module in the seat cushion has failed. I had a similar issue with VW which was a recall, however GM is not recalling these faulty vehicles. This could cause an airbag to not inflate during a crash.

Just paid $975 to have the passenger air bag sensor replaced on my 2013 Chevy Volt. I was informed by the GM Volt thread that this a manufacturing issue with the Chevy Volts and is happening to many Volt owners.

The passenger presence sensor failed in my Volt several years ago. Since it's no longer under warranty, the dealer quoted me $1000 to fix this issue. This is a critical safety issue and Chevy should recall these because it's a very common problem. The airbag is often not activated when I have a passenger due to the fact that the sensor has failed and can't sense a person in the seat. Critical safety issue! not to mention, the airbag warning light is intermittent and extremely obnoxious beeping multiple times every time I drive now. This seat has never been wet and the car has never been in an accident. Also, I rarely have passengers.

Passenger seat airbag sensor intermittently malfunctioning causing airbag to disable while passenger is present in the vehicle. Vehicle presents 'service airbag' message in the dashboard and passenger airbag indicator is set to off

- Bridgeview, IL, USA

The passenger airbag wont work because the sensor in the seat is broken. Chevy is charging over $1,000 to repair. There has never been an accident. It happened out of nowhere. When reading online this is happening to a lot of people and the repair cost is extremely high for something that is completely Chevy's fault.

The passenger side airbag sensor is failing. The car is not that old. We have had no spills in the car. But the airbag sensor is coming on. We paid the dealer $180 to look at it, but they found nothing wrong. Now the sensor light is coming on every time we start the car. It is out of warranty, and fixing will cost up to $1500. That is crazy. Many other people have had this problem with their Chevy Volts.

While in motion my car sporadically displays "service air bag system." Upon diagnosis, dealer stated the passenger presence module needed to be replaced. This car is only 5 years old with 77,000 miles. Seems like a serious safety hazard for this item to be failing. Researching Chevrolet Volt owner forum yields numerous cases of this same issue.

- Summerville, SC, USA

Service airbag message is on. Common problem for this car. The previous owner replaced an airbag sensor, and the problem has returned.

- San Jose, CA, USA

Air bag passenger seat occupancy sensor failure. When there is no passenger in the seat the air bag warning lite comes on. When an adult is in the seat the light does not come on unless the person moves around, then it comes on and then resets itself.

- Hilton Head Island, SC, USA

Passenger airbag sensor light came on and turns on and off randomly whether or not passenger is occupying the passenger seat. Unsafe if there is an accident as airbags won't deploy.

My 2013 chev Volt service air bag light comes on frequently. The dealership quoted me over $800 to fix it. I have read online others have this problem. I want my car to be safe. This should be a safety recall.

I would like to file a complain regarding a "service air bag" light present in my car. The light turns on suddenly regardless a passenger is present or not. It happens when the car is in motion or parked. I took the car to be inspected and the codes given were: B0081 and B0074 (passenger presence malfunction) the technician explained to me that if the part was not changed the passenger airbag may not deploy in case of an accident. My car has not been involved in an accident; it has not been exposed to any liquids that might have caused damage. The estimate provided and repairs were $980 (part only: $500) plus tax. So far, I was very satisfied with the quality of this car but it is very disappointing that something that is not negligence of the driver is not covered in the manufacturing warranty. Upon stumbling with this issue I realized that it is a common malfunction of this car from other owners as well. I would kindly ask you to take into consideration this issue and investigate it so that the company can issue a recall and customers no longer have to choose between a voluntary repair or not having a passenger airbag in case of an accident in such modern car.
