BMW has issued a wide-ranging recall on several of its model lines, ranging from the 1-Series to the Z4 sports car.

In total, there are 504,545 vehicles affected by the latest recall in the U.S. alone.

The recall affects:

- 2007-2012 BMW 1-Series Coupes and 1-Series Convertibles built from December 2007 through July 2011.

- 2007-2011 BMW 3-Series sedans built from March 2007 through October 2011.

- 2007-2011 3-Series Sports Wagons built from March 2007 through June 2011.

- 2007-2011 BMW 3-Series Coupes and 3-Series Convertibles built from March 2007 through July 2011.

- 2009-2011 Z4 roadsters built from March 2009 through June 2011.

The cause of the problem is a faulty battery cable connector, which may fail over time.

According to the automaker, the connector for the positive battery cable connector and the corresponding terminal on the fuse box on the affected vehicles may degrade over time due to high current flow and heat from electrical resistance. Should this occur, there could be a loss of electrical power to the vehicle, causing it to stall and possibly crash.

BMW is in the process of notifying owners of the affected vehicles. They will be requested to take their cars to their nearest BMW dealership, which will replace the positive battery cable connector and secure it with an improved method, free of charge.
