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

For the 2004 Kenworth T600. 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.

2004 Kenworth T600 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.

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.

April 28, 2005NHTSA 05V1890001,026 vehicles potentially affected

Suspension

Summary
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.
Consequence
This could cause sparks that could potentially ignite and cause a fire.
Remedy
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.
