2006 Kenworth T300 problems

What is wrong

On certain trucks equipped with cummins isc or paccar px8 engines, the jumper wire between the grid heater relay to the fuse block has been routed in such a way that the potential exists for it to rub against the radiator support.

Risk

The suspect wire is down stream of the fuse; this chaff point could cause the 250 amp charge wire to arc, potentially causing a fire.

Remedy

Dealers will inspect the routing of the jumper wire. If the wire is not routed correctly, it will be inspected for rubbing or chaffing and replaced if necessary free of charge. The recall began on june 22, 2007. Owners may contact kenworth at 425‑828‑5440.

What is wrong

On certain trucks equipped with hydraulic brakes, there may be a defect in the anchor bolt of some bosch model #305 parking brake assemblies. A different coating was applied to the bolt which did not meet paccar specifications. This could reduce the fatigue life of the bolt and lead to premature failure.

Risk

If this bolt were to fail, the truck could roll away while parked without warning, which could result in a crash.

Remedy

Dealers will inspect the parking brake assembly and replace the defective bolts free of charge. Peterbilt's recall began on november 4, 2005; and kenworth began on november 4, 2005. Owners may contact kenworth at 1‑425‑828‑5440 or peterbilt at 1‑940‑591‑4201.
