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."

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

Fix: 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.

The affected trucks are equipped with Michelin 295/60R22.5 XZA-2 front tires that have a speed rating less than the vehicle is governed to.

Risk: Higher vehicle speeds and other factors such as tire load and road temperatures may result in premature tire failure, increasing the risk of a crash.

Fix: Peterbilt will notify owners, and dealers will reprogram the engine's vehicle speed parameters to limit the maximum vehicle speed to the tire speed rating, free of charge.

Problem: Paccar is recalling model year 2008-2010 kenworth t300, t270, and t370, model year 2009-2010 t800 and peterbilt model year 2008-2010 335, 340, and 367 vehicles built on cummins' diesel engine. The vehicles may be designed with a hard wired, dash-mounted switch that enables the vehicle operator to inhibit aftertreatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures. 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.

Risk: 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.

Fix: Paccar is working with cummins to repair the engines free of charge please see 09e-046. The safety recall began on october 1, 2009. Owners may contact cummins at 1-800-diesels (1-800-343-7357).

Problem: Paccar is recalling 1,043 my 2008-2009 kenworth c500, t2000,t660, t800 and w900 trucks equipped with bendix mv-3 dash control valves. The molded valve body has an incorrect core pin in the injection mold causing the valve body to be oversized in the double check valve area. This condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.

Risk: 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.

Fix: Dealers will replace the bendix mv-3 dash control valves free of charge. The recall began on april 14, 2008. Owners may contact kenworth at 1-425-828-4196.
