JULY 2010 -- Paccar is recalling certain model year 2011-2012 Kenworth T660, T700, and T800 vehicles manufacturedfrom April 19, 2010, through May 13, 2011, and model year 2008, 2010 and 2011 Peterbilt 365, 367, 384, 386, 387, 388, and 587 vehicles manufactured from April 20, 2010, through June 11, 2011, and equipped with Paccar MX engines and Eaton Ultrashift DM or Allison automatic transmissions (without auto-neutral). The fast idle control may be activated by the operator while the transmission is in gear. If the fast idle control function is engaged with the transmission in gear, the vehicle could unexpectedly accelerate and override the parking brake and , creating a risk of a crash and damage to other vehicles or property and the potential for injury to nearby pedestrians. Kenworth and Peterbilt dealers will update the engine software for the affected chassis. This service will be performed free of charge. The safety recall is expected to begin during August 2011.   Kenworth and Peterbilt safety recall number is E038R. 11V-380

JUNE 2010 -- Paccar is recalling certain model year 2012 Peterbilt 587 tractors, manufactured from January 12, 2011, through May 20, 2011, equipped with Meritor's Maxton driveline assemblies. The tubing may have a seam weld with insufficient bonding. The affected driveline assemblies are RPL25 coupling shafts and slip shafts (main) driveline assemblies. This can result in seam weld fracture when torque is applied. Once the tube seam weld is fractured, the driveline may become inoperable which may result in a disabled vehicle or debris from the driveline may fall on the roadway, both of which can increase the risk of a crash. Dealers will replace the main drive shaft, free of charge. The safety recall is expected to begin during July 2011.   11V-331

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

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
