Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The defect: 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, DUE TO ITS UNIQUE BRAKE CLOCKING AND CAM TUBE LENGTH, CAN CAUSE FATIGUE AND CRACKING TO BRAKE ASSEMBLY COMPONENTS.
The risk: CRACKING CAN CAUSE A COMPLETE FRACTURE OF THE CAM TUBE, WHICH COULD INCREASE STOPPING DISTANCE AND DECREASE PARKING BRAKE HOLD CAPABILITY.
The remedy: 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. OWNER MAY CONTACT KENWORTH AT 1-425-828-5440.

140 units potentially affected
The defect: PACCAR IS RECALLING 140 MY 2005, 2007-2009 T800, W900, AND T660 TRUCKS. THE CALIPER MOUNTING FASTENERS ATTACHING THE AIR DISC BRAKE CALIPER ASSEMBLY TO THE TORQUE PLATE MAY HAVE RECEIVED INSUFFICIENT TORQUE DURING THE INSTALLATION PROCESS. THE INSUFFICIENT TORQUE MAY ALLOW THE AIR DISC BRAKE CALIPER ASSEMBLY TO BECOME LOOSE AND POSSIBLY SEPARATE FROM THE VEHICLE.
The risk: THIS COULD RESULT IN REDUCED BRAKING CAPACITY AND ALSO A ROAD DEBRIS HAZARD, INCREASING THE RISK OF A CRASH.
The remedy: DEALERS WILL INSPECT AIR DISC BRAKE CALIPER ASSEMBLIES AND REPLACE THE CALIPER MOUNTING FASTENERS AND TORQUE PROPERLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE MANUFACTURER HAS NOT YET PROVIDED AN OWNER NOTIFICATION SCHEDULE. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.
