An official CAA Japan notice concerns Passenger cars (Mercedes-Benz C220d Station Wagon, C220d 4MATIC All-Terrain) - Repair. Defect in the power transmission system (transmission control unit). ■ Defective component (part name): Electrical equipment (wiring). ■ Condition of the structure, equipment or performance considered noncompliant with standards, and its cause: Due to improper assembly during manufacture, some nuts at the body grounding terminal points for the 12V and 48V ground wiring in the engine compartment and under the floor were not tightened to the specified torque. Vibrations during driving and other factors may therefore loosen these nuts, increasing electrical resistance and generating heat that melts surrounding components. In the worst case, this may cause a fire. Published 2026-02-18.
