In the company’s largest recall to date, BMW will recall 1.3 million of their luxury cars because of a potential problem with a battery cable connector.

The affected vehicles include all BMW 5 Series Sedans and Sport Wagons produced between June 1, 2003, and March 31, 2010, and 6 Series Coupes and Convertibles produced between Sept. 1, 2003, and July 31, 2010.

“In some remote cases, the battery cable cover inside the boot [trunk] of these vehicles may be incorrectly mounted,” BMW said according to WSJ.com. “This can result in the electrical system malfunctioning, the vehicle failing to start and, in some cases, to charring or fire.”

The defect could prevent the car from starting and could lead to a fire. So far, the company says it knows of no accidents or injuries from the defect.
