These vehicles use a vacuum pump to supply power assist to the braking system. Due to insufficient lubrication this vacuum pump may fail. Failure of the brake vacuum pump would result in a reduction in braking power that could increase the risk of a crash. In order to correct this concern, dealers will install a locking ring in the camshaft to retain the camshaft seal disk in the proper location. This will ensure proper oiling of the vacuum pump. Note: This recall is an expansion of an earlier recall.

 

 

These vehicles use a vacuum pump to supply power assist for the braking system. The vacuum pump can fail unexpectedly due to insufficient lubrication. This would reduce braking efficiency, increasing the risk of a crash. Dealers will make modifications to allow for proper lubrication of the vacuum pump in order to correct this concern.

The vehicle battery is connected to the fuse box via a heavy duty cable. It has been determined that the cable connection at the fuse box can degrade over time, resulting in increased electrical resistance. This increased resistance can cause the connection point to overheat and break, resulting in a loss of electrical power and causing the engine to stall, increasing the risk of a crash. Dealers will replace the positive battery cable connector and secure it with an improved method to correct this concern.
