The 2020 Mercedes-Benz AMG GT63S has 3 recalls, the most serious involving a starter motor cable that can chafe surrounding wires, creating a short circuit that may stall the engine or start a fire.
The electronic stability control system carries a separate concern: a software error can cause it to react incorrectly to changing road conditions, meaning the system may fail to intervene when the vehicle begins to slide or may apply corrections at the wrong moment, raising the risk of a crash. There is also a communication system recall where the vehicle's reported GPS location can be inaccurate, which may cause emergency responders to be directed to the wrong location after a crash, delaying assistance.
