The car's air bag light by the speedometer has been illuminating intermittently at various speeds whether there is a passenger in the passenger seat or not. The passenger seat air bag on/off light near glove compartment turns to off when the speedometer air bag light illuminates. In June, I took the car into an independent mechanic to get the problem fixed. Unfortunately, the computer doesn't store a code for this problem. The mechanic tried to improve the connection to the passenger seat and "relearned" the computer; however, the problem still occurs. Mechanic said it "might" be a $1,000 fix which involves part of the passenger seat cushion itself! it cost me $100 to find out this much and attempt a correction, but $1,000 is ridiculous; especially for a "maybe" fix. I see others are having this problem, too. I've already had the ignition switch key fix at the dealership. I also already had the problem with the headlights turning off as we were driving down the road; our independent mechanic fixed that and I'm still waiting for the gm reimbursement on that. Hoping we can get gm to fix this air bag problem before it causes injuries.
Passenger air bag off indicator light comes on at times when seat occupied.
Air bag registered as off when a person was seated in the front passenger seat. Sensor was replaced and after 18 months the same problem is recurring. The air bag will be on then switch off and on all while a person is sitting in the seat and not doing anything other than sitting. Current mileage for 2nd recurrence is 46,150. Also the low beam headlights are going off for no apparent reason at night while driving down the road. High beams must be used when this occurs. The passenger door lock will not open or lock when the remote is used or the door lock button on the door. The hood will also not stay up as the hydraulic lifters do not hold.
