The 2023 Mercedes-Benz AMG GT43 has 5 recalls, the most serious being two separate fire risks: a loose 48-volt ground cable in the engine compartment that can overheat, and a transmission wiring harness connection that can short circuit.
The ground cable concern stems from a connection that may not have been tightened properly, allowing heat to build up to the point of ignition. The transmission wiring harness issue is related to incorrect wiring that in some cases traces back to a prior recall repair that did not fully resolve the problem. Both conditions can lead to a fire without warning.
The fuel system also has a concern worth noting: the fuel pump can shut down unexpectedly while driving, cutting power to the engine and leaving the driver without acceleration at highway speeds or in traffic, which raises the risk of a collision. There are two separate filings covering this same fuel pump shutdown issue across different model years and configurations, but the real-world result is the same.
Rounding out the list, a software error in the exit warning system can cause it to fail to display visual alerts or sound an audible warning when a vehicle or cyclist is approaching as a door is being opened, reducing the information available to occupants before they step out.
