2012 Peterbilt 320 problems

Defect

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."

Consequence

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.

Defect

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.

Consequence

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.

Defect

PACCAR Incorporated (PACCAR) is recalling certain model year 2009-2015 Peterbilt 320, 365, 367, 388, and 389 trucks manufactured July 21, 2008, to February 28, 2014. The front axle tie rod end clamp bolts may be improperly torqued.

Consequence

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.

Remedy

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 EXTREMELY COLD CONDITIONS, THESE BENDIX RELAY VALVES MAY POTENTIALLY DEVELOP INTERNAL LEAKAGE. INTERNAL LEAKAGE CAN LEAD TO AIR PRESSURE BEING DELIVERED TO AFFECTED PRIMARY OR SECONDARY BRAKE CAUSING CONTINUOUS BRAKE APPLICATION.

Consequence

UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE BRAKES TO OVERHEAT AND LEAD TO A FIRE. UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE DRIVER TO LOSE CONTROL OF THE VEHICLE, INCREASING THE RISK OF A CRASH. ALSO, THE BRAKES MAY BE APPLIED WITHOUT ILLUMINATING THE BRAKE LIGHTS, FAILING TO GIVE PROPER WARNING TO OTHER DRIVERS.

Remedy

PACCAR WILL NOTIFY OWNERS, AND PROVIDE A TEMPORARY REPAIR UNTIL BENDIX DEVELOPS A PERMANENT REMEDY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON FEBRUARY 10, 2012. OWNER MAY CONTACT KENWORTH AT 1-425-828-5440 AND PETERBILT AT 1-940-591-4196.

THE OIL MODULE CENTRIFUGAL SPINNER FILTER CAP IN THE PACCAR MX ENGINE MAY BECOME LOOSE, POSSIBLY ALLOWING THE CAP TO COME OFF AND ENGINE OIL TO PARTIALLY DISCHARGE FROM THE OIL MODULE ONTO EXHAUST COMPONENTS.
