The fuel pump may fail due to improper nickel plating during manufacturing. This can cause the engine to stall while driving. The dealership will replace the fuel pump free of charge to correct the problem.
BMW 335i Recalls
The bolts that secure the housing for the variable camshaft timing adjustment unit can loosen over time and possibly break, causing engine damage and engine stalling. Dealers will replace the four bolts for both intake and exhaust timing units free of charge to resolve the concern.
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.
The vehicle battery is connected to the fuse box via a heavy duty cable. It has been determined that the cable connection at the fuse box can degrade over time, resulting in increased electrical resistance. This increased resistance can cause the connection point to overheat and break, resulting in a loss of electrical power and causing the engine to stall, increasing the risk of a crash. Dealers will replace the positive battery cable connector and secure it with an improved method to correct this concern.
On certain vehicles, when extended to their highest position, the front seat head restraints exceed the allowable downward movement limit of 25mm, as determined by federal safety regulations. In the event of a crash, the head restraint may unexpectedly move down slightly if it was adjusted to the fully extended position, increasing the risk of personal injury. Dealers will attach a clamp to the front seat head restraint posts to correct this concern.
The front driveshaft attachment bolts may not have been tightened to specification and could become loose. This could lead to a loss of power to the front wheels and ultimately a vehicle breakdown, increasing the risk of a crash. Dealers will replace the front driveshaft attachment bolts to correct this concern.
An incorrect crimp connector may have been installed on the side air bag and belt tensioner wiring. There may be insufficient contact in the wiring, creating high resistance. This condition may cause the side air bag and/or safety belt tensioner not to deploy if needed in a crash, which increases the risk of injury. Dealers will repair the vehicles free of charge. The recall began September 16, 2009.
