ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM):SOFTWARE
Starting the vehicle while in gear may cause unexpected vehicle movement, increasing the risk of a crash or injury.
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.
Starting the vehicle while in gear may cause unexpected vehicle movement, increasing the risk of a crash or injury.
Driving without a functioning anti-lock brake system may result in the trailer not braking as intended, increasing the risk of a crash.
Safety systems that depend on the ECU (Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collison Mitigation System) may have diminished or lost functionality, increasing the risk of a crash.
An engine that does not return to idle quickly enough can cause a loss of vehicle control, increasing the risk of a crash.
Two 2023 MACK TERRAPRO (TE)s 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.
