Two problems related to air bag light on have been reported for the 2012 Chevrolet Suburban. The most recently reported issues are listed below.
My 2012 Suburban which I bought new in 2013 with 100 miles, after 3 years starting getting cracks in the dash. A month after the 3 year warranty expired. The passenger side crack runs from the air vent to the airbag door and now my service air bag light stays on. A larger crack (6+inches) has appeared on the drivers side running from the vent to the top of the steering column, if I continues the dash will completely separate in half exposing electronics, etc.
The airbag error indicator on the dash activates frequently, especially after driving several hundred miles in one day. When the error message is activated, the backup camera image is pixilated. It does not do it when the vehicle is in park. Chevrolet service technicians have been unable to recover the error code or replicate the error message. This is a continuing problem.
