The insulated 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. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.

 

The digital management control (EMC) unit may not have been produced according to specification. The engine may stall and not restart. As a result, a loss of power steering, and after repeated actuation of the brake pedal, a loss of brake power assist will occur. These conditions could result in a vehicle crash. Dealers will install a new (EMC) unit to correct this issue. This recall began on July 16, 2004.

Dealers will install a retention clip at the quick-release coupling on the fuel supply line. The recall began on July 5, 2004.
