The 2023 Mercedes-Benz AMG SL55 has 4 recalls, the most serious involving an unsecured wiring harness for the starter and alternator that can short-circuit, cut drive power, or overheat and start a fire.
Two separate recalls cover the fuel pump, which can shut down without warning and cut engine power while driving. The fuel pump issue spans a wide range of Mercedes-Benz models and model years, and prior repair attempts did not fully resolve it, resulting in a second recall campaign. There is also a concern with certain 80-amp fuses that were made incorrectly and can fail, potentially cutting drive power or disabling safety systems like the airbags and instrument cluster.
