2011 Kenworth T370 Recall

On certain trucks, the welds that attach the trailer hitch may crack due to improper welding. As a result, the hitch could detach from the truck while towing a trailer. Note: This recall only affects certain trucks with trailer hitches installed by Commercial Truck Equipment.

A trailer that detaches from a truck could create a risk of a crash.

Commercial Truck Equipment will notify owners by mail and instruct you to take your truck to a dealer to inspect the trailer hitch and repair or replace it, as necessary. You should stop using the trailer hitch until the inspection and repair have been completed.

On certain trucks, the warning light for the tractor anti-lock brake system (ABS) may not turn on if the system loses power. If this happens, the driver will not get warning that the ABS is not working properly. Note: This problem would also cause the traction control (TC) and electronic stability control (ESC) lights not to turn on.

If a driver is not warned that the ABS is not working properly, there could be an increased risk of a crash.

PACCAR will notify owners by mail and instruct you to take your truck to a dealer to update the software for the cab control module (CECU).

On certain vehicles, water could migrate into wiper motor head and could lead to internal corrosion. This internal corrosion could form a conductive salt bridge which could result in a short circuit, causing the wiper system to fail. Loss of windshield wiping capability, should it occur during a rainy/snowy day, may compromise the driver's ability to see the road and its users, and a short circuit could increase the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will install a shield over the wiper motor to protect it from water intrusions and prevent corrosion.

A failure of this component (electrical) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain vehicles, the slack adjuster housings may have been manufactured incorrectly, which could allow the housings to fracture and fail. As a result, the wheel brake to which the slack adjuster is attached would no longer function, which could increase vehicle stopping distances. Should a steer axle slack adjuster fail, it could also cause the vehicle to pull to one side during braking. Either problem could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the slack adjusters.

A failure of this component (brakes) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain trucks, the air governor was assembled with a blank plug instead of a breather. Without the breather, the air governor may not be able to detect the loss of pressure in the air system during normal use, which may result in a slow activation of the emergency spring brakes. Although the operator is warned of low air pressure by audible and visual warning alarms, a crash causing property damage, personal injury or death is possible if these warnings are ignored. Correction: Dealers will replace the blank plug with a breather, and inspect the system for proper function.
