The 2023 Mercedes-Benz AMG SL43 has 4 recalls, all rated at the same severity level, with the most serious being two electrical fuse issues that can cause a sudden loss of drive power or knock out critical safety systems including airbags and the instrument cluster.
The fuse concerns stem from two related problems. Certain 80-amp fuses were manufactured incorrectly and can fail in service, cutting power to the engine or disabling the restraint systems and instrument cluster entirely. A separate recall covers vehicles that received an incorrect fuse box during a prior repair, where a box not designed for this vehicle may have been installed, creating the same risk of sudden power loss or safety system failure. There is also a fuel pump issue that spans both of these recalls in scope: the fuel pump can shut down without warning, causing the engine to lose drive power while the vehicle is in motion. Prior repair attempts for one of the fuse concerns did not fully resolve the issue, which is why that fuse box problem appears as a distinct recall.
