My air bag warning light came on and when I investigated I found it was probably related to the front air bag sensors. When I examined the sensors I found that the aluminum alloy body and the plastic shield surrounding it had split wide apart where the steel mounting screw passed through the sensor housing. Both sensors have failed in exactly the same manor. The vehicle has 83,000 miles on it and does not have any other of advanced corrosion anywhere else. I contacted gm and they seemed to have no interest and advised me to take it to a dealer and have it repaired at my own expense.
