   Service Brakes, Air / Supply / Reservoir/Tank

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain 2009-2021 Kenworth C500, 2012-2021 Kenworth T440, 2009-2015 Kenworth T660, 2015-2024 Kenworth T680, 2009-2024 Kenworth T800, 2009-2020 Kenworth T370, 2014-2023 Kenworth T880, 2011-2016 Kenworth T470, 2023 Kenworth T480, and 2009-2019 Kenworth W900 vehicles. The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

   Consequence, in the NHTSA record

   Insufficient air volume can reduce braking performance and increase the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed August 12, 2024. Additional owner notification letters were mailed October 27, 2025. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 24KWD.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 24KWD. Owner notification date in the NHTSA record: 12 Aug 2024.

2. 20V199000Received 6 Apr 2020. 460,515 units.

   Service Brakes, Air / Antilock / ABS Warning Light

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

   Consequence, in the NHTSA record

   If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

   Remedy, in the NHTSA record

   PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020. The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 20pbc AND 20KWB. Owner notification date in the NHTSA record: 26 May 2020.

3. 11V203000Received 24 Mar 2011. 5,831 units.

   Engine and Engine Cooling

   Defect, in the NHTSA record

   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, in the NHTSA record

   This could result in a fire.

   Remedy, in the NHTSA record

   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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 11KWB & 0311-A. Owner notification date in the NHTSA record: 4 Aug 2011.

4. 11V127000Received 23 Feb 2011. 4,664 units.

   Fuel System, Other / Storage / Tank Assembly

   Defect, in the NHTSA record

   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, in the NHTSA record

   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, in the NHTSA record

   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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number E026R. Owner notification date in the NHTSA record: 4 Mar 2011.

5. 10V535000Received 27 Oct 2010. 417 units.

   Service Brakes, Air / Disc / Caliper

   Defect, in the NHTSA record

   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, in the NHTSA record

   As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash.

   Remedy, in the NHTSA record

   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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KWH. Owner notification date in the NHTSA record: 24 Nov 2010.

6. 10V308000Received 2 Jul 2010. 9,697 units.

   Steering / Column

   Defect, in the NHTSA record

   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, in the NHTSA record

   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, in the NHTSA record

   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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KW-F & 0610-D. Owner notification date in the NHTSA record: 30 Jul 2010.

7. 10V266000Received 16 Jun 2010. 4,796 units.

   Latches/Locks/Linkages / Hood / Latch

   Defect, in the NHTSA record

   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, in the NHTSA record

   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, in the NHTSA record

   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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KWE. Owner notification date in the NHTSA record: 15 Jul 2010.

8. 10V185000Received 4 May 2010. 21 units.

   Suspension / Rear / Axle / Spindle

   Defect, in the NHTSA record

   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, in the NHTSA record

   A wheel end fire may occur, increasing the risk of a crash.

   Remedy, in the NHTSA record

   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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KWB. Owner notification date in the NHTSA record: 24 May 2010.

9. 09V490000Received 23 Dec 2009. 3,078 units.

   Steering

   Defect, in the NHTSA record

   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, in the NHTSA record

   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, in the NHTSA record

   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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KWB. Owner notification date in the NHTSA record: 28 Jan 2010.

10. 09V415000Received 21 Oct 2009. 914 units.

    Power Train / Axle Assembly

    Defect, in the NHTSA record

    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, in the NHTSA record

    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, in the NHTSA record

    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.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KWA. Owner notification date in the NHTSA record: 4 Nov 2009.
