On certain trucks equipped with the optional Caterpillar Diesel Engine (LG5), the battery cable could come in contact with the exhaust pipe. The conduit and the nylon cable coating could degrade to the point where the copper wire strands of the cable are exposed. If the cable strands contacted the exhaust pipe, the short circuit could cause the battery cable coatings to ignite and possibly lead to an engine compartment fire. Correction: Dealers will inspect the battery cable for proper routing and reroute the cable if necessary.

On certain vehicles, the front air brake hoses can contact the inner fender extensions and eventually chafe through to the point of rupture. This would result in a partial brake system failure and increased stopping distances, which could result in a vehicle crash. Correction: A portion of the inner fender extension will be cut out and the front brake hoses will be inspected for chafing and replaced if necessary.
