Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary Information communication provides information to the technician about vehicles that have an intermittent no crank, no start, or start stall concern with the security light coming on. Technician may find Diagnostic Trouble Codes B3055, B3060, and/or B3935. Technician should not replace any parts for this concern. If unable to duplicate the concern ask if the customer uses any Radio Frequency Identification Devices when the concern is present. Dealer should also direct their customers to the appropriate section in the Owner manuals that references that the device complies.

The failure pattern owners describe
The passenger presence sensor—a safety-critical component that tells the airbag system whether someone is sitting in the front passenger seat—fails on thousands of 2012 Volts, usually between 60,000 and 100,000 miles. When it goes bad, the dashboard flashes "Service Airbag" warnings that come and go randomly, or stay on all the time. The real danger is that when the sensor fails, the car disables the passenger airbag even though someone is sitting there. A handful of owners have been in crashes with unfired airbags and sustained head injuries.
Owners say the sensor triggers false alarms when the seat is empty, misfires when a passenger shifts position or when the seat is adjusted, and sometimes only clears temporarily if you press hard on the seat. The failure rate and consistency across forums point to a design or manufacturing defect—not owner misuse. Repair quotes run $800–$1,200 to replace the module or entire seat assembly. GM opened NHTSA investigation PE19013 in 2019 and closed it in 2021, claiming they set up a cost-reduction repair program. Owners report that program does not exist; dealers have no record of it, and GM has discontinued the replacement part altogether. Independent shops cannot help because the work requires proprietary GM tools and programming software. Vehicles out of warranty are left owner-responsible for a component that should last the vehicle's life.

Failure modes owners describe
Passenger Presence Sensor / Passenger Sensing System (PSS) Malfunction
The passenger presence detection sensor embedded in or beneath the passenger seat fails to reliably detect occupants, causing the service airbag warning light to illuminate intermittently or continuously. When the sensor is faulty, the system may disable the passenger-side airbag (and in some reported cases, all airbags) even with an occupant present, or trigger false warnings when the seat is empty. The failure often worsens over time and can be reproduced by pressing on the seat, shifting seat position, or by heavier passengers.
When: Begins as early as 19,000 miles on some vehicles; typically emerges between 60,000–100,000 miles; some reports begin after routine service without apparent cause.
Symptoms owners cite: Service airbag warning light illuminates intermittently or continuously; Warning light activates when passenger is seated, then deactivates when they exit; Light blinks on and off rapidly while driving; Light activates randomly with no occupant in the seat; Sensor may toggle on/off with seat movement or when passenger shifts position; Airbag indicator shows airbag 'off' instead of 'on' when passenger is present; Pushing down on a section of the seat can temporarily clear the warning
Repairs/costs cited: Replacement of passenger presence module, sensor harness, or entire passenger seat assembly. Parts cost $400–$500; total repair cost $800–$1,200 including labor (typically $150/hour × 2–5 hours). Some owners report part discontinuation by GM, making repairs unavailable. Independent shops cannot perform the work due to GM patent on proprietary tools and programming equipment required.
Recalls/TSBs owners mention: In September 2019, NHTSA opened investigation PE19013 into malfunction of the Passenger Sensing System in 2012–2013 Chevrolet Volt vehicles. In July 2021, NHTSA closed the investigation after GM instituted a cost-reduction program for repair/replacement of the PSS. However, multiple owners report that GM denies knowledge of any such program when contacted, dealers cannot locate it, and the replacement part has been discontinued. GM warranty coverage applies only within 60,000 km (approximately 37,000 miles) or the bumper-to-bumper warranty period, leaving out-of-warranty vehicles owner-responsible.
Airbag Harness Disconnection (Seat Movement)
The passenger presence module harness beneath the passenger seat becomes disconnected when the seat is moved back and forth repeatedly. This causes intermittent or persistent sensor faults and warning light activation. GM issued a TSB addressing this condition.
When: Mileage not consistently reported; triggered by regular seat repositioning and adjustment.
Symptoms owners cite: Service airbag warning light illuminates when seat is adjusted forward; Warning clears when seat is moved to full rearward position; Module is undetected in forward seat position but detected in rearward position
Repairs/costs cited: Requires rewiring or securing of the harness. GM has issued a TSB for this condition.
Recalls/TSBs owners mention: GM issued a Technical Service Bulletin (TSB) advising dealers to rewire the harness; owners report dealers refused to perform this work at no cost.
Airbag Non-Deployment in Actual Crashes
Two owners reported being in motor vehicle accidents where the front airbags failed to deploy, resulting in head injuries. The failure to deploy occurred in vehicles with known passenger sensing system issues.
When: Deployment failure during crash events; one reported in a high-speed frontal collision (35–40 mph), another in a side-impact collision (25 mph).
Symptoms owners cite: Airbags did not deploy during frontal collision impact; Airbags did not deploy during side-impact collision; Head and neck injuries resulted from impact without airbag cushioning; One owner suffered concussion; another suffered memory loss and concussion
Repairs/costs cited: No repair attempted; vehicles not inspected post-crash for root cause of airbag failure.
