BMW Z4 RecallsAirbags May Not Deploy as Expected
On 51 vehicles, some electronic airbag system processors may not be compatible, which may cause the airbags not to deploy if they are needed in a crash. Dealers will inspect and replace the air bag system processors if needed. The recall began June 11, 2004.
In certain environmental conditions, the fuel pump may vapor lock, causing the engine to stall. If this were to happen while moving, the driver would not be able to maintain speed or accelerate, increasing the risk of a crash. 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.
On 180 vehicles equipped 18 inch tires, a front tire may have been damaged during production, when it was mounted on the rim.

The recall began July 14, 2003.
