2003 BMW Z4 recalls (4)

Tap a recall to see the problem, the risk and the fix.

Air bagsMay 24, 2004 · NHTSA campaign 04V247000 · 51 vehicles

Problem: On certain passenger vehicles, incompatible electronic air bag system processors may have been installed.

Risk: In the event of a crash, air bag deployment may not occur, increasing the risk of injuries to the driver and/or front passenger.

Fix: Dealers will inspect and, if necessary, replace the air bag system processors. The recall began june 11, 2004. Owners should contact bmw at 1-800-831-1117.

Fuel system, gasoline:delivery:fuel pumpApr 12, 2004 · NHTSA campaign 04V182000 · 13,769 vehicles

Problem: On certain passenger vehicles, under certain environmental conditions, a vapor lock in the fuel pump could occur causing the engine to stall. If this were to happen, the engine would not be able to be restarted for approximately 15 to 20 minutes.

Risk: If stalling were to occur, the driver would be unable to maintain vehicle speed or accelerate, increasing the risk of a crash.

Fix: Dealers will install a resistor in the electrical line powering the fuel pump in order to prevent an occurrence of vapor lock. The recall began may 11, 2004. Owners should contact bmw at 1-800-831-1117.

TiresJun 9, 2003 · NHTSA campaign 03V214000 · 180 vehicles

Problem: On certain vehicles equipped with 18" tires, it is possible that the tire has been damaged during the mounting process to the rim.

Risk: Consequently, a loss of tire pressure, or a tire failure, could occur. Depending on traffic conditions and the driver's reactions, this could lead to a crash.

Fix: Dealers will unseat the tire from its rim, inspect for any damage, and then reseat the tire to its rim. If inspection reveals that a front tire has incurred damage during the mounting process, it will be replaced. Owner notification began july 14, 2003. Owners should contact bmw at 1-800-831-1117.

Seat belts:front:buckle assemblyFeb 4, 2003 · NHTSA campaign 03V032000 · 2,635 vehicles

Problem: On certain passenger vehicles, the connection of the safety belt buckle to the steel rope of the tensioner does not meet bmw specifications. In severe frontal crashes, this connection can detach.

Risk: If the connection detaches, the protection provided by the safety belt is likely to be impaired, and serious injuries to the driver and/or front passenger could occur that might otherwise be mitigated.

Fix: Dealers will inspect both front safety belt tensioner and buckle assemblies, and if necessary, replace these parts. Owner notification began march 19, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact bmw at 1-800-831-1117.
