2011 Peterbilt 320 problems

What is wrong

PACCAR Incorporated (PACCAR) is recalling certain 1990-2020 Peterbilt 320 and 520 vehicles built with specific amber rear turn signals. The turn signals may also light up with the stop/tail lights when the brakes are applied. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk

Rear Turn signals that illuminate at the same time as the brake lights may create confusion and impair the effectiveness of the brake lights, increasing the risk of a crash.

Remedy

PACCAR will notify owners, and for trucks with rear amber lights, dealers will add a jumper harness between the chassis electrical harness and amber tail lights, free of charge. The recall began August 1, 2019. Owners may contact PACCAR customer service at 1‑940‑591‑4220. PACCAR's number for this recall is 19PBC.

Recall number 19V452000 · Recall details

What is wrong

PACCAR Incorporated (PACCAR) is recalling certain model year 2010-2016 Kenworth T440, T800, and W900 trucks manufactured August 31, 2009, to April 20, 2015, and 2008-2015 Peterbilt 320, 337, 348, 365, 382, and 384 trucks manufactured July 27, 2007, to April 28, 2015, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.

Risk

If engine oil comes into contact with a hot surface, there is an increased risk of a fire.

Remedy

Cummins will notify owners on behalf of PACCAR, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Kenworth customer service at 1‑425‑828‑5000, Peterbilt customer service at 1‑940‑591‑4000 or Cummins Inc. at 1‑800‑343‑7357. PACCAR's number for this recall is 15KWH and 515-G.

Risk
