My sensor on the passenger seat is faulty my airbag service light keeps on turning on and off consistently. Never had an accident or spills on the seat.

There is a capacitive field detector in the passenger seat also called a passenger position sensor. Instead of a simple buckle detector this part has failed in my car at 76,000 miles and the affect is that the passenger airbag is disabled. The part is apparently around 800$ as the entire seat assembly must be replaced. The indicator on the dash simply says to service the airbags. It may be anecdotal due to the intermittent nature of the failure but it seemed to clear when I accelerated and fail upon breaking, slowing down or going down hill. This seems like the exact opposite of when you'd want your airbags to become disabled.

The vehicle would issue a warning ding with a dashboard indicator saying, "service airbag." The dashboard airbag warning light would then illuminate. The warning would remain on for several minutes, then the warning light would extinguish. Initially the warning light would only illuminate when a passenger was riding in the front passenger seat, and even then would only happen infrequently. Over a six month period of time the airbag warning would occur more frequently, and eventually would illuminate even when a passenger was not in the vehicle. The dealership blamed the condition on either 1) the seat getting wet and damaging the sensor (which has never happened), or 2) the repeated act of placing my 10-20lb laptop backpack on the passenger seat (wouldn't a 200 lb passengers be more likely to damage a sensor than a 20lb backpack?).

Passenger pressence module sensor gets detoriated when the passenger seat moves back and forth. Basically ruining the too short wiring connecting to the sensors. This makes the airbag nondeployable. The computer thinks no one is sitting there, essentially. This occurred while driving and goes on and off, but has stayed on consistently.

The service airbag light is on, and the dealership says that it is the passenger side seat 'passenger presence module' that needs to be replaced, at a cost of over $800. The car is a 2013 with 79K miles, so is out of warranty, but I just find it really disappointing that this kind of manufacturer issue is not covered by the manufacturer through a recall or factory warranty. This isn't an issue of routine maintenance, and the car has never been in an accident, so it just does not seem like something I should have to pay $800 for.

My airbag sensor intermittently comes in and off. I took it to a Chevrolet dealership and they said it was the passenger seat airbag sensor and that it would cost about $900. I have read on a Volt forum that this is happening to many of us. This should be covered by GM.

Driving, so spills on seats, service airbag light goes on. $800. Fix at the local Chevrolet dealer. Why isn't there a recall on this fuse? I can't afford to fix it.I just purchased the car a year ago. No accidents, nothing amiss otherwise, love the car, gave up my newer prius to get this car.

Passenger presence module needs replacing at a dealer-quoted cost of $700. Rear seat stitching came apart, requiring several hours of repair. 2 bad 12 Volt batteries in 36,000 miles have somehow affected the main computer and I haven't received a quote yet. Bad oil line connection on the master cylinder. Mechanic said defective crimp. Bought the car in 6/15 at 16,000 miles with a reconstructed title. Air bags did not deploy in accident. I doubt that the accident influenced any of these problems. The car performed flawlessly for 10,000 after I bought it (except for the 12 Volt battery).

The contact owns a 2013 Chevrolet Volt. The contact stated that the air bag wiring connection under the seat had a short, which caused the sensor mat not to function. Henderson Chevrolet (240 N gibson rd, henderson, nv 89014, 702-558-2438) was notified. The manufacturer was notified and stated that the vehicle was not included in a recall. The manufacturer issued three tsbs for the air bags. The failure mileage was not available.

Sensor in passenger seat goes bad giving air bag error

- Orlando, FL, USA

"service airbag" lights intermittently. Original cause appeared to be movement of front passenger seat; recent causes were sudden braking and random normal speed cornering. Dealer attempted to reproduce problem, but unable. Dealer hand tightened wires under seat. Problem corrected for a few weeks, then returned. Suggested next step by dealer: Replace pps module. Unfortunately, this is $800+ repair with no guaranteed outcome. This problem has been reported by other Volt owners in internet posts. Would like to know if GM has any fixes not known to dealer.

Service air bag warning during or shortly after someone sits in front passenger seat. Also see the passenger air bag light illuminates "off" for extended period. Dealer states it is not able to duplicate the issue. Has been happening for the past year. Believe this is a known defect, and also a safety hazard, as air bag may not deploy in a collision.

- Pearland, TX, USA

Whenever someone sits in the passenger seat, the service airbag indicator comes on. Dealer reviewed codes and determined the airbag sensor is faulty. The service tech stated the passenger airbag will not inflate until this is repaired at a cost of $850. There are only 56,000 miles on the car, but the problem started around 40,000 miles.

Paid dealer $160 to find out passenger presence module had failed. They're asking for another $820 (mostly labor) to fix the issue by replacing with part #22968438 in the passenger seat...so I'm driving around with a bad airbag I guess. Can't see spending $1000 right now to fix a blinking warning light. I see on the web that others are also having this problem, and wonder how many Volt owners are driving with bad airbags waiting for a recall to be announced. Seems like a part that just shouldn't have much wear-and-tear, and should maybe never become an expensive repair issue. Engine, tranny, tires, etc. - sure. But not the dang airbag system.

Was entering highway in the dark and went to put the car into "hold" mode to run the gas engine and save battery charge. This requires pushing a button 3 times. I reached over and pushed the button. Accidently was pushing the "power" button which is right below the "mode" button shutting down the car. The entire car shuts off, no lights, powertrain, ps, pb just dead. This is easy to do if you are watching the road and just glance down to the buttons. They are placed too close together and this is going to be a serious problem if in traffic or on winding roads. Numerous reports of this on the Volt forum!
