Badly fitted starter positive cable on the AMG GT 63 4-door

Engine / equipment

4.0 V8 biturbo (M177) of the Mercedes-AMG GT 63 / 63 S 4-Door Coupé (also the E 63 S)

Period mentioned

2018–2021

Symptoms

The engine suddenly stalls; electrical faults; a burning smell in the engine bay.

Possible cause described

The starter motor positive cable may have been fitted incorrectly, letting the power-supply wires chafe; a short circuit can stall the car while driving and raises the fire risk. US recall 21V-217 for 2019–2021 model-year AMG GT 63 and 63 S 4-door cars and 2018–2021 E 63 S: the screw connections and the cable position are checked and corrected.

Check for the garage

Ask by VIN at a Mercedes dealer whether the starter-cable campaign was done.
