    Electronic Stability Control (ESC)

    Defect, in the NHTSA record
    PACCAR Incorporated (PACCAR) is recalling certain 2020-2021 Peterbilt 520 vehicles. The stability control brake relay may have the Spring Brake Modulating (SBM) Valve or the lift axle hose incorrectly connected.
    Consequence, in the NHTSA record

The axles may have lower rear pivot bolts that are not long enough to sufficiently engage the locking feature of the corresponding nuts.
    Consequence, in the NHTSA record

    Remedy, in the NHTSA record
    PACCAR will notify owners, and dealers will inspect suspect chassis and replace the pivot bolts, as necessary, free of charge. The recall began September 29, 2020.

    Steering / Electric Power Assist System

    Defect, in the NHTSA record
    PACCAR Incorporated (PACCAR) is recalling certain 2020 Peterbilt 520 vehicles. Incorrect bolts may have been used to secure the steering assist cylinder bracket, possibly allowing the bolts to loosen.

    Defect, in the NHTSA record
    PACCAR Incorporated (PACCAR) is recalling certain 2016-2020 Peterbilt 320 and 520 vehicles with dual foot valves and a liftable tag or tri-drive rear axles. The rear brake signal hose may be missing a quick release valve, possibly causing a delay in their brake release timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Disc Brakes."
    Consequence, in the NHTSA record

    Defect, in the NHTSA record
    PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T800, T880 and W990 and Peterbilt 348, 367, 389, 520, and 567 vehicles. The forward rear axle output shafts may have been improperly heat treated during manufacturing, possibly resulting in the shafts fracturing.
    Consequence, in the NHTSA record
    If the rear axle output shaft fractures, the shaft or interaxle driveline could detach and become a road hazard, increasing the risk of a crash.
    Remedy, in the NHTSA record
    PACCAR will notify owners, and dealers will inspect and replace the output shafts, as necessary, free of charge. The recall began February 19, 2020.
