Battery Light Due to Damaged Alternator Connector

The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.

2004 Ford Mustang Recalls

Gas Pedal May Stick and Cause Unexpected Acceleration

On some Mustang Cobra models, the unique rear surface of the accelerator pedal may catch the cutout in the floor carpeting and not allow the engine to return to idle. This could cause longer stopping distances and/or unexpected, continued acceleration, which may lead to a crash. Dealers will install a shield over the cutout in the carpet behind the accelerator pedal. The recall began April 26, 2006. The Ford recall number is 06S43.
