Bayerische Motoren Werke
Models: BMW Z3 Year: 1999
Number Involved: 1,000
Dates of Manufacture: August - September 1998
Defect: The nut that secures the main positive cable to the positive battery terminal clamp was not tightened properly, allowing the cable over time to loosen. If this occurs, the cable could ultimately loosen to the point where electrical continuity could be interrupted. If this occurs while the engine was running, the engine could stop. Also, if the vehicle were being operated at night, the lighting system could shut off, increasing the risk of a crash.
Remedy: Dealers will tighten the nut to the proper specifications. Owner notification began in late-November 1998. Owners who do not receive the free remedy within a reasonable time should contact BMW at 1-800-831-1117. [NHTSA Recall No. 98V275]
