Electrical system
- 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, the wiring, parts, or transmission programming required for the auto neutral feature to function as designed were either not installed, connected, or programmed properly.

Service brakes, air
- What is wrong
- Certain trucks fail to comply with the requirements of federal motor vehicle safety standard no. 121, "air brake systems." the trailer light line may have been routed using too tight of a bend radius. This routing method could cause the wires within the harness plug to be pulled away from the chassis plug resulting in an intermittent or complete electrical power loss to the trailer.
- Risk
- Should power be lost, the electrical circuits would not provide power to the antilock system on the towed vehicle increasing the risk of a crash.
- Remedy
- Dealers will reroute the light line to eliminate the excessive bend radius and replace any plug or harness that has been damaged free of charge. The recall began on april 16, 2007. Owner may contact kenworth at 425‑828‑5440.
