The front passenger seat contains a mat that determines the presence and size of a seat occupant. This input to the airbag controller helps to determine if and how forcefully the passenger airbag should deploy in the event of a crash. The detection mat can develop cracks and fail. If this were to occur, the airbag would not deploy as expected, increasing the risk of personal injury. Dealers will repair the occupant detection mat to eliminate the possibility it may crack. Additionally certain vehicles will receive and extended warranty on the front passenger seat occupant detection mat.
BMW 750i Recalls
Certain vehicles equipped with both the Comfort Access and Soft Close Door options are being recalled. Due to a software problem, the doors may appear to be closed and latched, but may not be. A door may unexpectedly open due to road or driving conditions or occupant contact with the door. The sudden opening may result in occupant ejection or increase the risk of injury in the event of a crash. Dealers will update the vehicle software as necessary to correct this concern.
The affected vehicles have an electronic key and an electronic connection between the gear shifter and the transmission (shift-by-wire) that automatically shifts the transmission to Park when the driver presses the Start/Stop button to shutdown the engine. If the driver presses the engine Start/Stop button 2 or 3 times within a short time interval, the system may shift the transmission to Neutral rather than Park.
If the driver exits the vehicle with the transmission in Neutral and the parking brake is not applied, the vehicle may roll away. Unattended rollaway incidents often result in a crash or cause injury to pedestrians in the path of the vehicle. Vehicle owners will be notified, but the revised software remedy will not be available until March 2013.
Vehicles equipped with an 8 or 12 cylinder turbocharged engine may overheat the circuit board for the auxiliary water pump. This could lead to smoldering of the pump or an engine compartment or vehicle fire. Dealers will replace the auxiliary water pump to correct this concern.
On vehicles equipped with an 8 or 12 cylinder turbocharged engine, the circuit board for the electric water pump may overheat. This could lead to smoldering of the pump and/or an electrical fire in the engine compartment. Dealers will replace the auxiliary water pump to correct this concern.
The brake system vacuum pump check valve can leak oil and contaminate the power brake booster. This can result in loss of power brake assist. Dealers will repair the vehicle as necessary free of charge to resolve concerns.
The lower rubber mount for the rear shock absorber may not have been manufactured properly and may not adhere to the housing. If it separates, the driver will experience impaired handling and control of the vehicle, increasing the risk of a crash. Dealers will replace the rear shock absorber. The recall began September 13, 2006.
