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

MARCH 2011 -- Paccar is recalling certain model year 2011-2012 Kenworth T270/370, T440/T470, T800, T660, W900 and C500 vehicles manufactured between October 18, 2010, and January 28, 2011. Certain cast iron slack adjuster housings, which transmit braking force from the brake chamber push rod to the brake cam tube, may include a flow notch in the handle portion of the housing due to an error during the casting process. A flow notch in the handle portion may reduce the effective cross section structure and cause the slack adjuster housing to fracture. If the slack adjuster housing were to fracture, the wheel brake to which
the slack adjuster housing is attached would no longer function, which could increase vehicle stopping distances, and if mounted on the steer axle, could cause the vehicle to pull to one side during braking, increasing the risk of a crash. Dealers will inspect and replace the slack adjuster housing as necessary. This service will be performed free of charge. The safety recall is expected to begin during April 2011.   Paccar safety recall No. 11KWA 11V-157

MARCH 2011 -- 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. This could result in a fire. 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 won't 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.   11V-203

FEBRUARY 2011 -- 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. The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire. 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.   11V-127

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

NOVEMBER 2010 -- Paccar is recalling certain model year Kenworth T660 and T800 vehicles manufactured from September 15, 2010, through November 9, 2010, for failing to comply with the requirements of Federal Motor Vehicle Safety Standard No. Part 567, "Certification." The steer axle GAWR and GVWR recorded on the vehicle's door labels may be inaccurate and overstate the actual load capacity of components installed on the vehicle. This may lead to an owner overloading the vehicle which can increase the risk of a tire failure and crash. Dealers will inspect and replace the door labels free of charge. The safety recall is expected to begin during December 2010.  10V-601

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

JULY 2010 -- 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. A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash. 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. Kenworth's recall campaign number is 10KW-F & Peterbilt's recall number is 0610-D. 10V-308

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

MAY 2009 --  Paccar is recalling 112,736 trucks equipped with caterpillar C15 engine. The variable valve actuation oil line may rub against the p-clips retaining the oil line, causing an oil leak.
