2011 Peterbilt 337 recalls

• Lights And Instruments#2020148April 7, 2020

  65,284 units affected

  Issue: On certain trucks, the warning light for the tractor anti-lock brake system (ABS) may not turn on if the system loses power. If this happens, the driver will not get warning that the ABS is not working properly. Note: This problem would also cause the traction control (TC) and electronic stability control (ESC) lights not to turn on. Safety Risk: If a driver is not warned that the ABS is not working properly, there could be an increased risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a dealer to update the software for the cab control module (CECU).

• Engine#2015211May 15, 2015

  169 units affected

  On certain vehicles equipped with Cummins Westport ISL-G engines, excessive engine crankcase pressure could cause the vent tube assembly elbow to detach from the breather. This could allow engine oil to come in contact with hot surfaces, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will install clamps at both ends of the elbow of the breather tube assembly and reprogram the Electronic Control Module (ECM) to improve diagnostic capabilities.

• Airbag#2014198May 29, 2014

  4 units affected

  On certain vehicles, a wiring defect could cause the airbag warning lamp to fail to illuminate in the event of a fault with the side curtain airbag system. As a result, a fault could go undetected by the driver, and cause the side airbag to fail to deploy in a crash. This could increase the risk of injury. Correction: Dealers will affect repairs.

• Brakes#2010147May 6, 2010

  14 units affected

  On certain vehicles, the terminal for circuit BRN5112-1 could be located in the incorrect cavity of the ABS Relay/Fuse block. Locating the harness in the incorrect cavity will cause the ABS malfunction indicator lamp to be illuminated at all times. The ABS brake system will not be affected by this condition, however, if there is a problem with the ABS system the driver will be informed, which could increase the risk of a crash causing property damage, personal injury or death. Correction: Dealers will reposition the incorrectly located ABS wiring terminal.

• Other#2010145May 4, 2010

  147 units affected

  On certain trucks, the hood anti-blowdown device (designed to prevent unintended and unexpected hood closure) can become hindered or inoperative due to unintentional latch movement which interferes with the hood pivot j-hook, latch misalignment, or latch fallout. An unintended latch closure can cause personal injury. Correction: Dealers will install hood anti-blowdown retention cables to the radiator and hood assemblies.
