13 recalls found in NHTSA data as of September 22, 2026

For the 2006 Kenworth T800. These apply to the model and year, not to one particular vehicle: check your VIN to see whether yours is included and whether it has been repaired.

Has your Kenworth been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Kenworth dealer can also check your VIN. Recall repairs are free.

2006 Kenworth T800 recalls, newest first

June 30, 2009NHTSA 09V2390003,423 vehicles potentially affected

Service brakes, air

Summary
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.
Consequence
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.

September 24, 2008NHTSA 08V485000130 vehicles potentially affected

Suspension

Summary
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.
Consequence
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.

March 9, 2007NHTSA 07V09000065 vehicles potentially affected

Service brakes, air

Summary
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.
Consequence
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.

November 30, 2006NHTSA 06V46100086 vehicles potentially affected

Trailer hitches › Fifth wheel assembly

Summary
On certain trucks, an RA529 king pin release air valve was manufactured with the internal spool installed backwards. This results in the air option of the king pin release system being inoperable. To correct this situation, the vehicle's air lines were reversed rather than replacing the valve.
Consequence
With the lines reversed, the king pin can be released without the driver's knowledge. When this occurs, the driver could drive away and the trailer could become disengaged, increasing the risk of a crash.
Remedy
Kenworth will inspect the king pin release system and suspect valve. If any vehicles have a nonconforming valve or incorrect plumbing, it will be replaced and re-plumbed. The recall began on November 29, 2006. Owners may contact kenworth at 1-425-828-5440.

Power train › Driveline

Summary
On certain trucks equipped with chalmers rear suspensions, the adjustable torque rod end castings may be brittle. A brittle rod end casting may fracture without warning, causing the vehicles' rear axles to become misaligned.
Consequence
This misalignment can cause the vehicle to lose directional stability at speeds that may result in a vehicle crash.
Remedy
Dealers will inspect the vehicles to determine if they were manufactured with a suspect torque rod end. If a suspect torque rod end is found, the entire torque rod will be replaced. The recall began on October 9, 2006. Owners may contact peterbilt at 1-940-591-4196 or kenworth at 1-425-828-5440.

Engine and engine cooling

Summary
On certain tractors equipped with caterpillar diesel engines, the variable valve actuation oil line may wear against the sharp edge of the cylinder head if not positioned correctly.
Consequence
The oil line may be cut on the cylinder head causing an oil leak and a possible fire.
Remedy
Caterpillar, in conjunction with paccar, will be conducting the owner notification and remedy for this campaign free of charge. Owners may call caterpillar at 309-675-6496, kenworth at 425-828-5440, or peterbilt at 940-591-4201.

November 29, 2005NHTSA 05V543000241 vehicles potentially affected

Steering

Summary
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.
Consequence
This condition could affect vehicle throttle control and braking, thereby leading to loss of vehicle steering control which could cause a crash without warning.
Remedy
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 esp system will be reactivated. The recall began on December 7, 2005. Parts to complete the remedy are estimated to be available in early 2006. Owners may contact kenworth at 1-425-828-5440 or peterbilt at 1-940-591-4201.
