2015 PETERBILT 320

SUSPENSION:MULTIPLE AXLE

PACCAR Incorporated (PACCAR) is recalling certain 2015-2023 Peterbilt 320 and 520 refuse trucks equipped with Haulmaax/EX suspensions. The suspension tracking rod brackets may fail and detach from the forward drive axle, causing the axle to become unstable.

Risk: An unstable axle can decrease vehicle stability and control, increasing the risk of a crash.

STEERING:COLUMN

PACCAR Incorporated (PACCAR) is recalling certain 2015-2021 Peterbilt 320 and 520 vehicles. The steering column support structure may crack or break in certain right-hand, stand-up drive models.

Risk: If the steering column loosens from the mounting structure, steering control can become affected, increasing the risk of a crash.

EXTERIOR LIGHTING:TAIL LIGHTS

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.

STEERING:LINKAGES:TIE ROD ASSEMBLY

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.

Risk: 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.

ENGINE AND ENGINE COOLING:ENGINE

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.

SERVICE BRAKES, AIR:DISC:CALIPER

PACCAR Incorporated (PACCAR) is recalling certain model year 2015 Peterbilt 210, 220, 320, and Kenworth K270, K370, T660, T800, T880 trucks manufactured July 21, 2014, to September 16, 2014. The brake caliper bolts may not be properly torqued.

Risk: As a result, the brake caliper bolts may loosen, reducing the effectiveness of the brakes and increasing the risk of a crash.

ENGINE AND ENGINE COOLING:ENGINE

PACCAR Inc, is recalling certain model year 2014-2015 Kenworth T440, T660, T800, and W900 tractor trailers manufactured January 23, 2013, through February 4, 2014, and certain model year 2014-2015 Peterbilt 320, 365, 382, 384 tractor trailers manufactured January 21, 2013, through February 5, 2014, and equipped with certain Cummins Westport Model ISL G and ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.

Risk: The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.

FUEL SYSTEM, DIESEL

PACCAR Incorporated (PACCAR) is recalling certain model year 2015 Kenworth K270, T270, K370, T370, T440, T470, and W900 chassis manufactured May 13, 2014, to July 23, 2014, and certain model year 2015 Peterbilt 210, 220, 320, 325, 330, 337, 348, 365, 382, 384, and 567 chassis manufactured May 8, 2014, to July 22, 2014. The Cummins ISB or ISL engines in these vehicles may have been equipped with Fleetguard UFF-XT fuel filters, part number FF63009, whose filter shell may separate from the fuel filter nut plate causing the engine to stall without warning.

Risk: If the engine stalls unexpectedly there is an increased risk of a crash.
