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 loss of communication between the gear shifter and the transmission may result in the vehicle becoming disabled after coming to a stop, increasing the risk of a crash.
Unintended vehicle movement can increase the risk of a crash or injury.
A detached flywheel can cause loss of drive power, increasing the risk of a crash. Additionally, driveline pieces may be ejected from the engine compartment, increasing the risk of injury.
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 KENWORTH W990s 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.
