2006 Kenworth T600 Recall

Certain vehicles may suffer cracking of various brake assembly components (i.e. brake cam tube mounting flanges, brake air chamber bracket, brake air chamber, brake spider). Over time, this cracking can cause a complete fracture of the cam tube, which could increase stopping distances and decrease parking brake hold capability. A reduction of braking capability could increase the risk of a crash causing property damage, personal injury or death. Correction: Dealers will inspect the rear axle brake assembly, replace cracked rear axle brake components where required, and install cam tube support brackets on all rear axle wheel ends.

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 vehicles equipped with a Caterpillar C15 engine, the Variable Valve Actuation (VVA) oil line may wear against the P-clip retaining the oil line. An oil leak could result in a vehicle fire causing property damage and/or personal injury. Correction: Caterpillar dealers will replace the VVA oil line with an updated version.

A failure of this component (engine) 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).

Certain vehicle configuration which includes an AG400 rear suspension, long stroke brake chambers, and wide base tires may develop an increase in lateral and vertical axle movement. This movement may cause part or parts of the brake assembly to develop fatigue cracks, possibly resulting in the failure of part or parts within the brake assembly. A failure may reduce vehicle brake performance, increasing the risk of a crash causing personal injury or death. Correction: Dealers will affect repairs.

A failure of this component (suspension) 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 inadequate stiffness of the Diesel Particulate Filter (DPF) bracket could result in the separation of the DPF from the chassis, which could result in personal injuries or death to motorists or bystanders. Correction: Caterpillar dealers will replace bracket as necessary.

A failure of this component (other) 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 removable front tow hitch assembly may fail. This could result in personal injury or property damage if the assembly failed during the un-decking or towing of a vehicle. Correction: Dealers will replace the tow pin assembly with a revised version.

A failure of this component (other) 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 equipped with Caterpillar C11, C13 and C15 engines, the oil fill cap can become dislodged due to cap damage or improper installation. The cap can become lodged in the u-joint of the steering driveline and steering gear, causing difficulty steering the vehicle and/or complete steering lock-up. A loss of steering control can result in a vehicle crash causing injury or death. Correction: Dealers will install an oil cap retention chain to C11 engines and will modify the existing retention chain anchor point on C13 and C15 engine. Damaged oil fill caps will be replaced.

A failure of this component (engine) 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 equipped with a Caterpillar engine, the Variable Valve Actuation oil line (VVA line) used on 6 cylinder, 15L turbocharged and air-to-air aftercooled diesel engines may wear against the sharp edge of the cylinder head if not oriented correctly. Oil line wear may cause an oil leak and a potential fire hazard. Correction: Dealers will inspect and, if required, replace the VVA line.

A failure of this component (engine) 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 steering shaft sensor of the Electronic Stability Program (ESP) may be misaligned, giving incorrect vehicle information to the Electronic Control Unit (ECU). This could affect vehicle throttle control and braking systems. Correction: Dealers will first disable the yaw-control function of the ESP system. Once parts are available, the dealer will replace the steering column to insure proper alignment of the steering shaft sensor, and reactivate the full ESP system.

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

On certain vehicles, the rear suspension sway bar could fail causing the rear axle to come loose. As a result, the driver may experience a loss of vehicle control which could cause a crash without warning, possibly resulting in property damage, personal injury or death. Correction: Dealers will affect repairs.

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