Two problems related to air bag on-off switch have been reported for the 2013 Chevrolet Volt. The most recently reported issues are listed below.
The passenger seat occupancy sensor fails was failing. The check airbag warning light would come on while driving with a passenger in the vehicle. This would disable the airbag (when the check airbag indicator light indicating that the passenger airbag is enabled switches to off. ) this is a dangerous failure. If the car knows that the sensor has failed then the �safe� condition should be to deploy the airbags or the �seat occupied� condition should be �latched true� until the vehicle stops. (a passenger cannot suddenly disappear when the car is moving at 35 or 40 mph). This happened repeatedly in 2020 and 2021. Vehicle was taken to dealer to address the issue - was told that the issue was resolved. Shortly afterwards the issue started again. Vehicle was taken back to the dealer April-2021 and I was told that the seat occupancy sensor had failed and needed to be replaced.
Service air bag warning comes on often when there is a passenger in the car. Will beep and come back on every time the pasenger moves. Even with no passenger it will sometimes come on. When it does come on, the air bag display will switch to off. This happens whether stationary or moving and on any type of road. This has been going on for a long time due to the extremely expensive fix of the passenger seat sensor.
