What can fail
The fuel pump may unexpectedly shut down, causing the engine to lose power while driving.
What the fix does
The fuel pump will be replaced at no cost to you at an authorized Mercedes-Benz dealer.
The 2022 Mercedes-Benz AMG SL55 has 4 recalls, the most serious involving an unsecured wiring harness for the starter and alternator that can short-circuit, cutting drive power without warning or overheating to the point of causing a fire.
The fuel system accounts for two recalls that describe the same underlying problem: the fuel pump can shut down unexpectedly, cutting power to the engine and leaving the driver without acceleration, which raises the risk of a crash particularly in highway or merging situations. The fourth recall affects vehicles equipped with a heated leather steering wheel. A fault in that system can deactivate the hands-off detection feature, which disables parts of the DISTRONIC driver assistance system, including the alert that tells the driver to take the wheel and the automatic call to emergency services that triggers during an Active Emergency Stop.
