Recalls for the 2005 Chevrolet Trailblazer: 2
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. Testing has indicated that the aftermarket leather seat covers can cause the passenger sensing system to malfunction. 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.
Certain sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 212, 'windshield mounting.' the windshield urethane bead may not have adhered to the body in certain areas during the cure process. If a crash occurs, the windshield may not be retained, increasing the risk of injury to a vehicle occupant.
