The 2022 Mercedes-Benz AMG GT43 has 6 recalls, the most serious involving two separate electrical fire risks: a loose 48-volt ground cable in the engine compartment that can overheat, and a transmission wiring harness that can corrode or short-circuit.
The transmission wiring issue has a history worth noting: a prior recall repair on some vehicles may not have fully resolved the problem, meaning the wiring harness connection could still be incorrectly routed or improperly wired even on vehicles that were previously serviced. Both wiring concerns can result in an electrical fire. On the fuel system side, the fuel pump can shut down without warning while driving, cutting drive power entirely and leaving the vehicle unable to accelerate or maintain speed in traffic. Prior recall filings covering the same fuel pump concern across multiple model years reflect the same underlying defect, not a separate issue. The final recall affects vehicles equipped with a heated leather steering wheel: a fault in the hands-off detection system can disable the DISTRONIC driver assistance features, which normally alert the driver to return their hands to the wheel and can contact emergency responders during an automatic emergency stop if the driver becomes incapacitated.
