Recall number 20V199000 · Recall details

Engine and engine cooling: engine: dieselReported September 3, 2009 · 135 vehicles affected

What is wrong: 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.
Remedy: 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).

Recall number 09V348000 · Recall details

Service brakes, hydraulicReported April 29, 2009 · 2 vehicles affected

What is wrong: Paccar is recalling 2 my 2009 kenworth t270 and t370 4x2 trucks. The anchor plate tie bar which reinforces the anchor plate on 73mm calipers was not installed. Under high torque brake applications the slide pins could bind, resulting in a reduction of the braking effort and/or brake drag caused by incomplete brake release; or the anchor plate could fatigue, resulting in a cracked and/or fracture anchor plate.
Risk: This condition could result in reduced braking capacity and increased stopping distances, or part of the anchor plate could separate and fall onto the roadway. Either of these could increase the risk of a crash.
Remedy: Dealers will inspect the brakes on the affected chassis for the presence of the anchor plate tie bar; and install the anchor plate tie bar if missing free of charge. All vehicles have been fixed. Owner may contact kenworth at 425‑828‑5440.
