Estimate your repair exposure
Drag to your current mileage. Numbers are derived from this vehicle's complaint history.
Certain vehicles originally built with cloth seats that were equipped with an automatic air bag passenger sensing system and later reupholstered with aftermarket leather seat cover kits are involved
If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. In either case, in the event of a crash that requires air bag deployment, a front passenger's level of injury may be increased.
Fix: Because a replacement leather seat cover that is compatible with the passenger sensing system is not available, general motors (gm) will repurchase these vehicles in accordance with the terms stated in gm's letter to owners. The recall began on november 6, 2006. Owners should contact gm at 1-877-477-1022 to begin the process of repurchasing their vehicle.
Certain sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no
If a crash occurs, the windshield may not be retained, increasing the risk of injury to a vehicle occupant.
