Increased resistance at the electrical contact points may cause damage to the ground terminal and housing of the connector. This can result in an intermittent or permanent loss of one or more rear lamp functions (tail, brake, turn-signal, reverse). Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash. Dealers will replace the rear lamp bulb carriers to correct this concern.

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.
