Complaints are reports from owners of this model year, not findings about any particular vehicle, and a model that sold in large numbers will collect more of them. They are counted here as filed; nothing is inferred from them.
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.
A fuel leak in the presence of an ignition source increases the risk of a fire.
The pressure plate may tear the diaphragm, causing a loss of air pressure and increasing the risk of a crash.
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.
Two 2021 PETERBILT 348s 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.
