The insulated bulkhead connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. As it loosens, an increase in electrical resistance at this cable connection is possible and could cause the cable connection to overheat. The problem could result in the electrical system malfunctioning, the vehicle failing to start and, in some cases, charring or fire, the press release continued.
According to the National Highway Traffic Safety Administration, BMW will notify its customers about the recall in writing.
Roughly 1.3 million cars worldwide are affected, with about 367,000 BMWs affected in the U.S.
