NHTSA defect investigations

NHTSA's investigations file lists the 2008 Kenworth T660 in 2 investigations. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.

Driver not Warned when ABS Offline/FMVSS 121, 136

NHTSA #20V199000 · Electronic Stability Control (ESC) · NHTSA notice

Reported April 6, 2020 · PACCAR Incorporated

Potentially affected: 460,515 vehicles

Repair completion: 33.98% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Manufacturer campaign 20pbc AND 20KWB · Owners notified May 26, 2020

Defect description

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."

Safety consequence

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

Manufacturer remedy

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.

THIS CONDITION CAN ALLOW THE RUBBER DOUBLE CHECK VALVE TO BECOME LODGED IN THE BODY OPENING UNDER CERTAIN CIRCUMSTANCES.

Safety consequence

IF THE DOUBLE CHECK VALVE BECOMES LODGED, IN THE EVENT OF A PRIMARY RESERVOIR FAILURE, AIR PRESSURE CAN LEAK PAST THE LODGED DOUBLE CHECK VALVE THEREBY DEPLETING THE SECONDARY RESERVOIR, CAUSING REDUCED ABILITY FOR MODULATING THE SERVICE EMERGENCY BRAKES. IN SUCH AN EVENT, THE OPERATOR SHOULD OBSERVE AN AIR LEAK, INDICATIONS OF LOW AIR PRESSURE VIA THE PRIMARY AND SECONDARY AIR GAUGES, AND AUDIBLE AND VISUAL LOW AIR PRESSURE WARNING ALARMS. A VEHICLE CRASH IS POSSIBLE IF THESE WARNINGS ARE NOT HEEDED.
