Electrical System 8 Read
What's wrong. Certain trucks equipped with eaton fuller ultrasonic transmissions fail to comply with the requirements of federal motor vehicle safety standard no. 102, "transmission shift lever sequence, starter interlock and transmission braking effect." the cab transmission harness could have been incorrectly wired during production installation
Risk. This could cause the neutral start feature of the transmission to disable allowing the vehicle to start in gear increasing the potential for a crash
Fix. Dealers will repair the connections in the wiring harness if necessary. Owner notification began on may 7, 2004. Owners should contact kenworth at 1-425-828-5440
What's wrong. On certain trucks equipped with a combination of caterpillar c11/c13 engines and an optional leece neville brushless alternator, a chaffing point may exist between a heat shield on the engine and the wiring for the alternator
Risk. This could lead to an electrical short or arc situation which could result in an engine fire
Fix. Dealers will change the alternator to a brush-type alternator that is shorter in length and provide the necessary clearance to all surrounding components. The recall began august 31, 2004. Owners should contact kenworth at 1-425-828-5440
What's wrong. On certain trucks, the power feed harness p92-1993 terminals were not properly crimped
Risk. This could lead to intermittent power loss affecting the electrical system and possibly result in a fire
Fix. Dealers will replace the harness. The recall began january 13, 2005. Owners should contact kenworth at 1-425-828-5440
Suspension 7 Read
What's 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
Fix. 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
What's wrong. On certain trucks and tractors equipped with airglide high-articulation rear suspensions, the c65-1006 sway bar used in this rear suspension may experience a reduction in fatigue life due to either a manufacturing process or a high induced stress during an extreme suspension articulation event
Risk. Both of these conditions can lead to a failure of the sway bar which could cause the rear axle to come loose, increasing the risk of a crash
Fix. The inspection and repair of these vehicles will depend on the type of vehicle (tractor or truck) and the intended service application. This inspection and repair criteria will be forthcoming. The recall began on june 30, 2005. Owners may contact kenworth at 1-425-828-5440
What's wrong. On certain heavy duty class 8 trucks, the suspension has transverse beam castings that may fracture under normal loads. If a casting breaks when the vehicle is traveling on a roadway there is the potential for pieces of the casting to become projectiles and the suspension's transverse beam may drop down low enough to contact the road surface
Risk. This could cause sparks that could potentially ignite and cause a fire
Fix. Dealers will inspect and replace the defective transverse beam assemblies free of charge. The recall began on june 10, 2005, with letters being mailed to peterbilt owners; and on june 17, 2005, for kenworth owners. Owners may contact peterbilt at 940-591-4201 or kenworth at 425-828-5440
Steering 6 Read
What's wrong. On certain trucks equipped with the bendix electronic stability control (esp) system, the system uses multiple sensors and an electronic control unit (ECU) to control vehicle under steer, over-steer, and rollover situations. The system relies on vehicle sensors to be functioning and aligned properly. The steering angle sensor has the potential to be misaligned with the steering column shaft, thereby providing incorrect information to the bendix ECU
Risk. This condition could affect vehicle throttle control and braking, thereby leading to loss of vehicle steering control which could cause a crash without warning
Fix. Because of the immediate and substantial risk, kenworth and peterbilt dealers will first deactivate the yaw control feature of the bendix esp system preventing inadvertent esp activation. When parts are available, the steering column will be replaced to insure proper alignment of the steering shaft sensor and the full…
What's wrong. Vehicle description: heavy duty trucks equipped with trw tie rod ends on certain meritor axles. The tie rod and drag link ball stud ends contain bearings that are below the specified case depth and/or hardness

Power Train 4 Read
What's wrong. On certain trucks built with the optional dana spl driveline, the u-joint fasteners at the output yoke of the transmission were not properly tightened
Risk. If the u-joints were to become loose, a portion of the driveline could become detached from the vehicle and fall out from under the vehicle, which could cause a crash
Fix. Dealers will verify the torque of the u-joint fasteners. Parts showing excessive wear will be replaced. The recall began on november 12, 2004. Owners should contact kenworth at 1-425-828-5440

What's wrong. Vehicle description: heavy duty trucks equipped with eaton autoshift gen ii transmission assemblies. Due to a software problem in the transmission assemblies, the transmission will select the wrong gear
Risk. If an inappropriate gear is selected without the driver's knowledge, the vehicle will react differently than expected, possibly resulting in injury or crash
Fix. Dealers will replace the autoshift transmissions. Eaton performed the campaign for the kenworth portion. However peterbilt will be conducting their own campaign
Service Brakes, Air 3 Read
What's 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
Fix. 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

What's 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
Fix. 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

Frequently asked questions
How many recalls does the Kenworth T600 have?
39 NHTSA campaigns on record, covering 1990–2005. Not every campaign applies to every car — coverage is by production range, so check your VIN.
Is recall work free?
Yes. Safety recall repairs are free at any franchised dealer regardless of the car's age, mileage or how many owners it has had. That is a federal requirement, not a courtesy.
How do I know if my T600 still has an open recall?
Enter its VIN above. We show campaigns that apply to that exact vehicle and whether the repair has already been recorded as done.
Why did a defect take years to be recalled?
On this model the average gap between the car being built and the defect being admitted is 1.23 years, and the slowest campaign came 5 years later. Defects usually surface as they accumulate in the field: complaints pile up, an investigation opens, and only then is a campaign issued.
