Recalls for the 2009 Buick Enclave: 8
The driver's air bag inflator may explode during deployment, due to a manufacturing defect. An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.
The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury.
In the affected vehicles, the flexible steel cable that connects the seatbelt to the front outboard seating positions may fatigue and separate over time. If the steel cable becomes fatigued and separates, the seatbelt may not properly restrain the seat occupant increasing the risk of an injury in a crash.
In the affected vehicles, increased resistance in the driver and passenger seat mounted side impact air bag (SIAB) wiring harnesses may result in the SIAB and seat belt pretensioners not deploying in the event of a crash. Failure of the side impact air bags and seat belt pretensioners to deploy in a crash increase the risk of injury to the driver and front seat occupant.
The second row seat side trim shield restricts the upward rotation of the safety belt buckle when the seat back is returned to a seating position after being folded flat. If the buckle contacts the seat frame, additional effort is required to return the seat to a seating position. The safety belt may not restrain the occupant as intended during a crash, increasing the risk of injury to the seat occupant.
However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. It is possible for the heated washer module to ignite and a fire may occur.
These vehicles fail to comply with federal motor vehicles safety standard 102, "Transmission shift position sequence, starter interlock, and transmission braking effect", and FMVSS 114, "Theft protection and rollaway prevention". The driver may not be able to restart the vehicle and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning.
16,667 my 2009 Buick enclave, Chevrolet traverse, GMC acadia, and Saturn outlook vehicles for failing to conform with the requirements of federal motor vehicle safety standard no. 209… In a vehicle crash, if the rivet is missing, the buckle may separate from the mounting strap, increasing the risk of injury to the passenger.
