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

For the 2007 Kenworth T660. 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.

2007 Kenworth T660 recalls, newest first

March 24, 2011NHTSA 11V2030005,831 vehicles potentially affected

Engine and engine cooling

Summary
Paccar is recalling certain model year 2007-2011 kenworth C500, T2000, T600, and T660, as well as model year 2009-2011 peterbilt 387 and 388 trucks equipped with caterpillar C15 engine and manufactured from may 11, 2006, through September 17, 2010. Degradation of a combustion tube weld can cause radial heat impingement on the body which may burn through certain bodies used on C15 engines.
Consequence
This could result in a fire.
Remedy
Caterpillar is handling the owner notification and remedy for this campaign. Please see caterpillar's defect report 11E-006. Caterpillar will replace the single piece combustion tube with a thick wall combustion tube which will not allow the heat to break through. This service will be performed free of charge. Due to a parts supply issue, owners will be notified by the end of April 2011 about the safety defect, and will then be notified again once the free remedy is available, currently estimated to be around late July 2011. Owners may contact caterpillar toll-free at 1-800-447-4986.

Fuel system, other › Storage › Tank assembly

Summary
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.
Consequence
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.

Power train › Axle assembly

Summary
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.
Consequence
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.

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.

Service brakes, air › Disc

Summary
Paccar is recalling 140 my 2005, 2007-2009 T800, W900, and T660 trucks. The caliper mounting fasteners attaching the air disc brake caliper assembly to the torque plate may have received insufficient torque during the installation process. The insufficient torque may allow the air disc brake caliper assembly to become loose and possibly separate from the vehicle.
Consequence
This could result in reduced braking capacity and also a road debris hazard, increasing the risk of a crash.
Remedy
Dealers will inspect air disc brake caliper assemblies and replace the caliper mounting fasteners and torque properly. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule. Owners may contact kenworth at 1-425-828-5440.

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.
