Recall number 11V203000 · Recall details

What is wrong

Paccar is recalling certain model year 2008-2012 kenworth t2000, t660, t700, t800, and w900, as well as model year 2009-2012 peterbilt 365, 367, 384, 386, 387, 388, 389, and 587 trucks equipped with paccar mx engines. The oil module centrifugal spinner filter cap in the paccar mx engine may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto exhaust components.

Risk

The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire.

Remedy

Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap. This service will be performed free of charge. The safety recall is expected to begin during march 2011. Owners may contact kenworth at 1‑425‑828‑5440 and peterbilt at 1‑940‑591‑4196.

Recall number 11V127000 · Recall details

What is wrong

Paccar is recalling certain model year 2007-2008 kenworth and peterbilt vehicles manufactured from february 2, 2006 through april 30, 2007. 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 lubrication and/or excessive heat. Prematurely worn bearing surfaces may result in the u-joint becoming loose and/or binding. This condition may result in universal joint failure, allowing the inter-axle driveline to detach from the axle.

Risk

Detachment of the driveline from the axle may cause the vehicle to lose power and become disabled in the roadway. Also, the driveline could drop from the vehicle into the roadway increasing the risk of a crash.

Remedy

Paccar is working with its supplier to remedy the vehicles free of charge. The safety recall is expected to begin during february 2011. Owners may contact kenworth at 425‑828‑5440 and peterbilt at 940‑591‑4196.

Recall number 10V634000 · Recall details

What is wrong

Kenworth is recalling 3,423 my 2004-2009 t2000, t800,t600, w900 and t660 vehicles. Increased brake excitation in a certain vehicle configuration which includes bendix drum brakes, wide base low profile single tires, and an ag400 or ag460 rear suspension, due to its unique brake clocking and cam tube length, can cause fatigue and cracking to brake assembly components.

Risk

Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability.

Remedy

Dealers will inspect the rear axle brakes assembly, replace cracked rear axle brakes assembly components where required, and install cam tube support brackets on all rear axle wheel ends free of charge. The recall is expected to begin or before july 25, 2009. Owner may contact kenworth at 1‑425‑828‑5440.

Recall number 09V239000 · Recall details

What is wrong

Paccar is recalling 130 my 2004-2009 t2000, t800, t600, w900 and t660 kenworth trucks built with an ag400 rear suspension, long stroke brake chambers, and wide base tires (super singles). These vehicles may develop an increase in lateral and vertical axle movement. This movement may cause part or parts of the brake assembly (brake cam tube support, brake chamber bracket, brake chamber, brake spider) to develop fatigue cracks, possibly resulting in the failure of the part or parts within the brake assembly.

Risk

A failure may reduce vehicle brake performance, increasing the risk of a crash.

Remedy

Dealers will install the cam tube support brackets on all of the rear axle wheel ends. Inspect the rear axle brake assembly and replace it if cracked. The recall is expected to begin during november 2008. Owners may contact kenworth at 1‑425‑828‑5440.

Recall number 08V485000 · Recall details

What is wrong

Paccar is recalling 4,883 my 2006-2009 kenworth t600, t660, t800, w900, t2000 and my 2008-2009 peterbilt 365, 367, 379, 384, 386, 387, 388 and 389 trucks. Inadequate stiffness of the diesel particulate filter (dpf) bracket could result in separation of the dpf from the chassis.

Risk

A vehicle crash could occur if another vehicle strikes the dpf on the roadway.

Remedy

Paccar is working with caterpillar to repair these vehicles (please see 08e041). Owners may contact caterpillar at 1‑800‑447‑4986 or kenworth at 1‑425‑828‑5440 or peterbilt at 1‑940‑591‑4196.

Recall number 08V487000 · Recall details

What is wrong

Paccar is recalling 3,573 my 2007 kenworth c500, t800, t600, t2000, and w900 chassis built with phillips qcs ii trailer cable connection and trailer cable mounting bracket with 'u-shaped' cut out. Certain trailer cable mounting brackets have a 'u-shaped' cut out that only partially supports the trailer cable connection. Partial support of the cable connection may allow the molded boot and electrical ground pin to partially or completely pull away from the 7-way socket. Partial or complete detachment of the cable connection can cause reduced water resistance and potential loss of electrical ground. There is also a possibility the trailer lights may fail to illuminate without the operator's knowledge.

Risk

If this condition were to occur, other motorists may not be warned of the tractor/trailer movements, increasing the risk of a crash.

Remedy

Dealers will install a reinforcement bracket between the flexible back of the qcs ii molded boot and the frame bracket, and reattach the supporting bolts. The recall began on may may 30, 2008. Owners may contact kenworth at 1‑425‑828‑5440.

Recall number 08V190000 · Recall details

What is wrong

On certain trucks equipped with caterpillar c11, c13 or c15 engines, the oil fill cap can become dislodged due to cap damage or improper installation and become lodged in the u-joint of the steering driveline and steering gear.

Risk

If the cap becomes dodged in this area, it may result in difficulty steering the vehicle or cause complete steering lock-up increasing the risk of a crash.

Remedy

Paccar is working with caterpillar to repair these vehicles. Revised oil cap retention based on the engine model/configuration will be incorporated to prevent steering lock-up. The recall began during december 2007. Owners may contact caterpillar at 1‑800‑447‑4986 or kenworth at 425‑828‑5440.

Recall number 07V279000 · Recall details

What is wrong

On certain trucks, the removable tow hitch ,when used to tow or lift a vehicle, can fail due to defective material in the tow hitch.

Risk

If the tow hitch assembly fails while a vehicle is being towed or lifted, it may cause an accident that could result in personal injury or death.

Remedy

Dealers will replace the tow pin assembly free of charge. The recall began on september 4, 2007. Owners may contact kenworth at 425‑828‑5440 or peterbilt at 940‑591‑4201.

Recall number 07V269000 · Recall details

What is wrong

Certain trucks fail to comply with the brake timing regulatory requirements of federal motor vehicle safety standard no. 121, "air brake systems." the brake valve was moved to the opposite rail, increasing the length of the air line, which in turn increased the wheelbase requiring a dual relay valve system. The vehicles were manufactured with a single valve system.

Risk

If stopping distance was limited, a vehicle crash could result.

Remedy

Dealers will convert the single relay valve to a dual relay valve system free of charge. The recall began on may 21, 2007. Owners may contact kenworth at 425‑828‑5440.

Recall number 07V090000 · Recall details

What is wrong

An incorrect switch was installed in the cruise control system on certain model t300 trucks.

Risk

A light application of the brakes will not deactivate the cruise control and the system will have to be shut off by the dash switch. This could lead to unintended acceleration and a crash without warning.

Remedy

Kenworth will install the correct sensor switch. The recall began on january 10, 2007. Owners may contact kenworth at 1‑425‑828‑5440.
