2007 Kenworth T660 Recall

On certain trucks equipped with a Caterpillar C15 diesel engine, the Diesel Particulate Filter (DPF) combustion tube may fail. This could result in a vehicle fire causing property damage and/or personal injury. Correction: Dealers will replace the DPF combustion tube.

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 PACCAR MX engine, the oil module centrifugal spinner filter cap may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto nearby exhaust components. The discharge of engine oil onto hot exhaust components could result in a fire causing property damage and/or personal injury. Correction: Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap.

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 bearing surfaces of the extended lube universal joint that attaches the inter-axle driveline to the drive axle may become prematurely worn due to breakdown of the lubrification and/or excessive heat. Prematurely worn bearing surfaces may result in the u-joint becoming loose and/or binding. If undetected, the condition may result in universal joint failure, allowing the inter-axle driveline to detach from the axle, which may cause the vehicle to become disabled in the roadway. Lost propulsion, in conjunction with traffic, road conditions, and the driver's reactions, could increase the risk of a crash. In addition a driveline component separating from the vehicle could strike another vehicle, stationary object, or bystander, causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the interaxle driveline universal joint.

A failure of this component (powertrain) 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 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, the caliper mounting fasteners attaching the air disc brake caliper assembly to the torque plate may have received insufficient tightening torque during the assembly process. Insufficient torque may allow the caliper mounting fasteners and/or the caliper itself to become loose. This could cause the brake on the affected wheel end to become inoperable. Extended stopping distance could result in a vehicle crash causing property damage, personal injury or death. Correction: Dealers will replace caliper mounting fasteners and inspect the caliper assembly.

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).

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).
