Recalls, owner-reported complaints, investigations and safety data

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.
0
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.

Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

SummaryOn July 13, 2010, the Office of Defects Investigations (ODI) opened an investigation on model year (MY) 2007-2009 Peterbilt tractors equipped with the (SPL170XL extended lube inter-axle driveline).ODI opened this investigation based on one Vehicle Owners Questionnaire (VOQ) and certain Peterbilt field reports.During the course of the investigation, ODI reviewed PACCAR's IR (October 22, 2010) response with associated data related to Warranty and complaint information, mined field data, interviewed customers and visited local dealers within the Washington Metropolitan area.PACCARconducted testing regarding torsional loading and identified various causative factors contributed to this safety defect finding.The Defect is a consequence of the bearing surfaces of the SPL170XL extended lube universal joint that attaches the inter-axle driveline to the drive axle becoming prematurely worn due to a 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, which may cause the drive shaft to separate from the vehicle, increasing the risk of personal injury or property damage hazard.ODI learned that the affected population of the alleged defect extended to peer models within PACCAR.In summary, the following vehicles are being recalled: MY 2007 and 2008 Kenworth trucks, models T600, T660, T2000, T800 and W900 and MY 2007/2008 Peterbilt trucks, models357, 378, 379, 385, 386, 387, 388, and 389 allequipped with extended lube inter-axle drivelines manufactured by Dana Corporation.The recall affects vehicles manufactured between February 2, 2006 and April 30, 2007.At this time PACCAR has not yet identified a fix for the inner-axle safety defect and is currently conducting testing with the intent to provide a solution to the failure.ODI will monitor the development of PACCARS testing and ensure a timely repair for the consumer.This investigation is closed.
