Battery monitoring software may not warn of a battery fault (2022–2023)
Safety recall- Chassis:
- V297 (EQS 450+, EQS 580, AMG EQS 53)
- Years:
- 2022–2023
- Engine:
- Electric
About 3,800 2022–2023 EQS sedans, plus some 2023 EQE 350 and S 580e models, were recalled because the high-voltage battery monitoring software might not alert the driver to a battery malfunction, which fails the federal electric-vehicle safety standard (FMVSS 305). Dealers update the battery management software. It is a software-only fix, so confirm completion through the VIN. Without the warning, a driver may keep using a vehicle whose battery needs attention.
