MAY 2011 -- Paccar is recalling certain model year 2011-2012 Kenworth T440 tractors manufactured between October 18, 2010, and February 9, 2011 for failing to comply with Federal Motor Vehicle Safety Standard No. 121, "Air Brake Systems." The quick release air valve required in the full truck service brake air line gladhand connection may not have been installed. The omission of the quick release air valve may allow the full truck service brake air line gladhand release timing to exceed the threshold of 0.75 seconds by 1/10th of a second, thereby failing to comply with the requirements of the safety standard. The service brake of a towed vehicle or trailer may have a delayed release, increasing the risk of a crash. Kenworth dealers will install the quick release air valve in the full truck service brake air line with gladhand connection. The recall is expected to begin by the end of June 2011.  Kenworth safety recall no. 11KWC. 11V-281

DECEMBER 2010 - 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. 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. Paccar is working with its supplier to remedy the vehicles free of charge. The safety recall is expected to begin during February 2011. 10V-634

DECEMBER 2010 - Kenworth is recalling certain model year 2011 T660 and T700 tractor trailers manufactured between august 9, 2010, and November 4, 2010. The safety latch feature that keeps the hood of the vehicle from closing after a user opens the hood may fail to operate. Failure of the safety latch feature may cause the hood to unexpectedly close while open, increasing the risk of personal injury and/or vehicle damage. Dealers will replace the dual magnets with a single magnet on the safety latch. This service will be performed free of charge. The safety recall is expected to begin during January 2011. 10V-654

OCTOBER 2010 -- Paccar is recalling certain model year Kenworth T660, T700, T800 and W900 vehicles manufactured from December 22, 2010, 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. As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash. Dealers will verify the correct orientation of the brake caliper and perform the necessary repair free of charge. The safety recall is expected to begin during November 2010.   10V-535

OCTOBER 2010 -- Paccar is recalling certain model year Kenworth and Peterbilt vehicles. A manufacturing defect in the seal supplied by a component manufacturer installed on the output shaft of the exhaust gas recirculation (EGR) valve actuator may cause eventual delamination of the seal. Delamination of the seal may allow engine oil to leak from the EGR valve onto exhaust components. The leaking of engine oil onto hot exhaust components, such as when the engine is under significant load, may create the possibility of a fire. Dealers will replace the EGR valve assembly on the subject vehicles equipped with the Paccar MX engine. This service will be performed free of charge. The safety recall began on October 29, 2010.   10V-453

SEPTEMBER 2010 -- Kenworth is recalling certain model year 2011 T660, T800, W900, C500, T440, and T470 vehicles manufactured from April 1, 2009, through August 30, 2010. One of the four harness spade terminal connections to the chassis load center may become completely unseated. A completely unseated connection may result in a power loss to a portion of the vehicle's exterior lighting. Power loss of the vehicle's exterior lighting may reduce the visibility of the vehicle to other drivers increasing the risk of a crash with the vehicle. Dealers will inspect the harness and re-seating the female connectors on the male spade terminals. This service will be performed free of charge. The safety recall is expected to begin during October 2010.    10V-452

JUNE 2010 -- 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. 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. 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 is expected to begin during June 2010.  Kenworth"s safety recall number is 10KWE. 10V-266

MAY  2010 -- 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. A wheel end fire may occur, increasing the risk of a crash. 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 is expected to begin during June 2010.  10V-185

MAY  2010 -- Kenworth is recalling certain model year 2011 T270, T370, and T800 trucks manufactured from January 28 through March 19, 2010, equipped with DV-2 air governor containing part number G90-1070- 2111111 on the T270/370 model trucks and part number G90-1070-11113111 on the T800 model trucks. The DV-2 air governor was misassembled with a blank plug instead of a breather. Without the breather installed, the air governor may not be able to detect the loss of air pressure in the air system during normal use. This condition may result in the slow activation of the emergency spring brakes. Although the operator is warned of low air pressure by audible and visual low air pressure warning alarms, a vehicle crash or fire is possible if these warnings are not heeded. Kenworth will notify owners and repair the vehicles by replacing the blank plug with a breather and inspect for proper function free of charge. The safety recall is expected to begin during June 2010.   Kenworth's campaign number is 10KWD. 10V-211

MAY  2010 -- Kenworth is recalling certain model year 2009 through 2011 C500 trucks manufactured from October 24, 2008 through January 13, 2010. During maneuvers with certain combinations of wheel turn, articulation, and bump, the brake chamber can contact the rear hood support. The contact can damage the brake chamber leading to a loss of braking function at the affected wheel end, increasing the risk of a crash. Kenworth will notify owners and dealers will repair the vehicles free of charge. The safety recall is expected to begin during June 2010.  . Kenworth's recall number is 10KWC. 10V-212

APRIL 2010 -- Kenworth is recalling certain model year 2010 T270 and T370 trucks equipped with non-LMS hubs. The spindle nut attaching the hub and bearing to the axle spindle (steer or drive) may have been over-torqued during the hub installation process.

Dealers will replace the bearings free of charge. The spindle and hub will be inspected for scoring and replaced if necessary. The safety recall is expected to begin during May 2010.   10V-150

SEPTEMBER 2009 -- PACCAR is recalling model year 2008-2010 Kenworth T300, T270, and T370, model year 2009-2010 T800 and Peterbilt model year 2008-2010 335, 340, and 367 vehicles built on Cummins" diesel engine. The vehicles may be designed with a hard wired, dash-mounted switch that enables the vehicle operator to inhibit after treatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures. Due to an issue with the logic in the ECM software in these engines, the switch may not function correctly, leading the operator to believe that the switch is in "inhibit" mode when it is not. This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, or a fire. Paccar is working with Cummins to repair the engines free of charge please see 09E-046. The safety recall is expected to begin during September 2009. 09V-348

JUNE 2009 -- Kenworth is recalling 13 MY 2009 T2000 vehicles for failing to comply with the requirements of Federal Motor Vehicle Safety Standard No. 106, "Brake Hoses." Air tube expander fitting used between the air tube inlet and dash air gauges for the trailer does not meet the burst pressure requirements. This can result in brake hose rupture, air pressure loss, and compromised vehicle braking which could result in a crash without warning. Dealers will inspect and replace the expander fitting which is related to 1,200 PSI. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule.  09V-227

JUNE 2009 -- Kenworth is recalling 9 MY 2009 T800S vehicles equipped with Dana front axle. The brake spider mounting fasteners attaching the brake spider to the front steer axle flange may have received insufficient torque during the installation process. The insufficient torque may allow the brake spider fasteners and brake spider to become loose. This can allow the fasteners to shear and fall either onto the roadway or into the drum brake assembly, potentially allowing the brake to bind and causing increased stopping distance and a crash could occur. Dealers will inspect and replace the brake spider mounting fasteners and torque them properly, as well as review the brake spider and steer axle flange holes for signs of vibration and fatigue and replace if necessary. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule.  09V-229

JUNE 2009 -- 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, can cause fatigue and cracking of brake assembly components. Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability. 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.  09V-239
