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

For the 2010 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.

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.

Service brakes, air › Disc › Caliper

Summary
Paccar is recalling certain model year kenworth T660, T700, T800 and W900 vehicles manufactured from December 22, 2008, through August 2, 2010, and equipped with AG400L air disc brakes. The air disc brake caliper could be installed on the wrong side of the drive axle potentially causing interference with the suspension bracket and the rear suspension as the outermost brake pads wear and the floating caliper moves inboard.
Consequence
As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash.
Remedy
Dealers will verify the correct orientation of the brake caliper and perform the necessary repair free of charge. The safety recall began on November 24, 2010. Owners may contact kenworth at 425-828-5440.

Steering › Column

Summary
Paccar is recalling certain model year 2008-2010 trucks equipped with TRW steering shafts. The circumferential weld around the steering shaft tube that welds the splined tube to the non-splined tube may be mislocated. Mislocation of the circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.
Consequence
A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash.
Remedy
Dealers will inspect the steering shaft using a weld placement gauge provided by TRW. Any steering shaft found to have been welded improperly will be replaced free of charge. The safety recall began on July 30, 2010. Owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.

Latches/locks/linkages › Hood › Latch

Summary
Kenworth is recalling certain model year 2009 through 2010 T660 tractor trailors manufactured from July 1, 2008 through July 31, 2009. The retaining pins securing the hood strut lock tube to the hood strut assembly may become loose and fall out allowing the lock tube to rotate on the strut assembly. In its normal operation the safety latch feature is automatically set and it prevents the hood from closing. With the hood closed and the retaining pins missing, the lock tube may rotate relative to the good strut resulting in a non-operational safety latch feature when the hood is opened.
Consequence
A non-operational safety latch feature may not be detected by an operator increasing the risk of personal injury and/or vehicle damage should the hood unexpectedly close.
Remedy
Dealers will replace the pivot disc and lock tube retaining pins with a revised pivot disc and cap screws. This service will be performed free of charge. The safety recall began on July 15, 2010. Owners may contact kenworth at 1-425-828-5440.

Suspension › Rear › Axle › Spindle

Summary
Kenworth is recalling certain model year 2010 T2000, T660, T800 and W900 vehicles manufactured between July 30, 2009 and September 18, 2009. The rear axle outer end hub may have not been primed with oil properly during the rear axle installation process. Potential lack of oil may cause the outer end bearing to heat up and/or seize, possibly resulting in the overheating of the wheel end.
Consequence
A wheel end fire may occur, increasing the risk of a crash.
Remedy
Dealers will replace the bearings, seals and will add oil to the outer end hub as well as inspect races and axle housing for damage and replacing as necessary free of charge. The safety recall began on may 24, 2010. Owners may contact kenworth at 425-828-5440.

Steering

Summary
Kenworth is recalling model year 2010 T2000, T800, T660 and W900S trucks manufactured between July 1 and October 23, 2009. The fasteners attaching the steering gear to the front drive bracket may have received insufficient torque during the installation process resulting in less than required clamp load.
Consequence
The insufficient clamp load may allow the fastener(s) to become loose and fall away from the vehicle resulting in road debris. If multiple fasteners were to become loose, the vehicle steering may wander, which could result in a crash.
Remedy
Dealers will inspect and re-torque the steering gear mounting bolts free of charge. The safety recall is expected to begin during January 2010. Owners may contact kenworth at 1-425-828-5440.

Power train › Axle assembly

Summary
Kenworth is recalling model year 2009 through 2010 T2000, T800, T660 and W900 trucks manufactured between November 12, 2008 and September 30, 2009. The axle u-bolts attaching the axle to the suspension leaf spring on certain AG400L rear suspensions may have received insufficient fastener torque during the installation process. The insufficient torque may allow the axle u-bolt to become loose, which may cause vibration in the rear suspension.
Consequence
If multiple fasteners were to become loose, the rear axle may shift relative to the rear suspension leaf spring, which can result in loss of control and a crash.
Remedy
Dealers will inspect the axle u-bolts for visible defects, including bent and/or smashed threads and re-torque the axle u-bolts to factory specifications. The recall began on November 4, 2009. Owners may contact kenworth at 425-828-5440.
