PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020. The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

Undertorqued tie rod end clamp bolts are susceptible to corrosion, which may cause loose bolts to separate resulting in a loss of vehicle control and an increased risk of a crash.

PACCAR will notify owners, and dealers will replace the front axle tie rod assembly on any vehicle where the factory installed assembly has not been previously replaced, free of charge. Owners were mailed interim notices on May 11, 2015. The recall began on April 4, 2016. Owners may contact Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 215-C.

In the affected vehicles, if power is interrupted to the seat electronic control unit (ECU), such as when the fuse for that circuit blows, the side air bag would be disabled but there will not be a warning lamp indicator to notify the operator of the malfunction.

Without a warning of a problem existing in the side air bag system, the driver may continue to operate the vehicle, increasing the risk of injury from the side air bag not deploying in the event of a rollover.

PACCAR will notify owners, and dealers will install a new electrical harness to correct them problem, free of charge. The recall began in July 2014. Owners may contact Peterbilt customer service at 1-940-591-4220. Paccar's number for this recall is 514-F.

PACCAR, Inc. (PACCAR) is recalling certain model year 2008-2013 Peterbilt 365, 367, 388, 389 trucks manufactured October 6, 2007, through September 23, 2013.

Thus, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

The improper brake configuration could lengthen the braking distance needed to stop the vehicle, increasing the risk of a crash.

PACCAR will notify owners and dealers will install new 16.5" x 7" brake shoes with ES-600 linings, free of charge. The recall began on June 20, 2014. Owners may contact at Peterbilt at 1-800-473-8372. Peterbilt's number for this recall is 314-D.

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)."

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.

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.

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.
