Recall campaigns 6 of 6
21V720000
SERVICE BRAKES, AIR
A missing quick release valve cannot ensure correct rear brake release timing, increasing the risk of a crash or injury.
21V391000
FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL
A fuel leak in the presence of an ignition source increases the risk of a fire.
21V004000
STEERING:COLUMN
If the steering column loosens from the mounting structure, steering control can become affected, increasing the risk of a crash.
20V739000
ELECTRONIC STABILITY CONTROL (ESC)
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.
20V506000
POWER TRAIN:AXLE ASSEMBLY
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.
This page is about a model, not a car
Two 2021 PETERBILT 520s can have entirely different histories, and a recall campaign usually covers a build-date window rather than a whole model year — which a VIN does not encode, so only the door-jamb label settles it. Scanning the VIN adds the decode, the crash tests, the fuel economy and the complaints matched to that exact engine, trim and assembly plant.
