Peterbilt 520 recalls
Risk: A steering cross-shaft that fails can cause a loss of steering control, increasing the risk of a crash.
Risk: Delayed and unsteady headlights can result in insufficient illumination of the road, decreasing the driver's visibility and increasing the risk of a crash. In addition, an unexpected position change of the lift axles may increase the risk of injury.
Risk: A loss of drive power increases the risk of a crash.
Risk: Safety systems that depend on the ECU (Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collison Mitigation System) may not function properly or at all, increasing the risk of a crash.
Risk: A loss of steering control increases the risk of a crash.
Risk: A broken ball stud can cause a complete loss of steering control, increasing the risk of a crash.
Risk: An improperly installed wheel end hub assembly can leak oil, causing the axle spindles to loosen or fracture and increasing the risk of a crash.
Risk: A loss of steering control increases the risk of a crash.
Risk: A rear lifting bracket that detaches while the engine is being lifted can result in the engine falling or swinging, increasing the risk of injury.
Risk: An unstable axle can decrease vehicle stability and control, increasing the risk of a crash.
Risk: An unexpected engine stall can increase the risk of a crash.
Risk: A fractured steering gear can cause a loss of steering control, increasing the risk of a crash.
Risk: Fastener failure can result in a loss of steering control, increasing the risk of a crash or injury.
Risk: A missing quick release valve cannot ensure correct rear brake release timing, increasing the risk of a crash or injury.
Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.
Risk: If the steering column loosens from the mounting structure, steering control can become affected, increasing the risk of a crash.
Risk: A stability control event meant to only actuate the ABS controlled wheel ends could actuate lift axle brakes or modulate park brake chambers and could possibly de-stabilize the vehicle, increasing the risk of a crash.
Risk: The short screws can cause the hardware to separate from the suspension system and become road hazards, increasing the risk of a crash and/or injury.
Risk: Loose bolts may cause the bracket to flex or break, potentially damaging adjacent components or locking up the steering, increasing the risk of crash.
Risk: A delayed brake release may increase the risk of crash.
Risk: The improperly mounted steering assist cylinder bracket may break and cause damage to surrounding components and/or lock up the steering, increasing the risk of a crash.
Risk: 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.
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.
Risk: An unexpected engine shut down can increase the risk of a crash.
