One problem related to air bag has been reported for the 1999 GMC Suburban. The most recently reported issues are listed below.
Coming back home from a trip to niagra fall, our GMC Suburban 1999 rolled over 5 times. One of the tire (driver side front) exploded and right rear back tire shredded. Which caused truck to rollover. We were in little falls, were taken to st. Elizabeth hospital in utica. Our oldest daughter 11 got the most injuries. She has gotten 60 stitches on her face etc. Air bags of the vehicle did not deploy. Wondering why ????.
