- What is wrong
- PACCAR Incorporated (PACCAR) is recalling certain model year 2006-2016 Peterbilt 587, 579, 567, 389, 388, 387, 385, 382, 379, 378, 367, 365 and 357 trucks manufactured July 25, 2005, to February 26, 2016. The affected vehicles may be equipped with Tire and Rim Certification Labels that list a tire pressure below the actual correct amount. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 120, "Tire selection and rims and motor home/recreation vehicle trailer load carrying capacity information for motor vehicles with a GVWR of more than 4,536 kilograms (10,000 pounds)."
- Risk
- If the tires are underinflated due to the incorrect inflation pressure listed on the label, the truck may not be able to carry the maximum gross vehicle weight rating (GVWR) load listed without experiencing tire failure which would increase the risk of a crash.
- Remedy
- Peterbilt will notify owners and mail them a corrected Tire and Rim certification label, free of charge. The recall began on June 19, 2015. Owners may contact Peterbilt customer service at 1‑940‑591‑4000. PACCAR's number for this recall is 215-D.

Power train: axle assembly
- What is wrong
- 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.
- Risk
- 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.

Defect investigations
Driveshaft separates from tractor
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.

Horton fan hub failures
There are 84,573 subject and peer (kenworth) vehicles.subject vehicles are model year 2007 through 2008 paccar trucks built with a horton fan hub assembly.the ea will include peer vehicles (kenworth's with horton fan hubs) in the subject population.there are a total of 1,645 warranty claims on the combined population.odi surveyed warranty claim owners and found that a significant number of the failures resulted in a disabled vehicle.odi also believes that certain models are more prone to failure and further analysis is warranted to understand the differences in failure rates. Odi is concerned that a large disabled vehicle is at an increased risk of being struck in the rear by another vehicle.odi is also concerned that this failure mode provides little warning and therefore, a driver has less opportunity to remove the vehicle from the travel lanes or shoulder, once a fan separation has occurred.odi will conduct further risk assessment during the ea to gain an understanding of the warning, options available to the driver and the increased risk of the truck being struck in the event of a breakdown.the federal safety agency has upgraded pe09-002 to an ea (ea09-008) to further investigate this matter.
