The 2023 Mercedes-Benz EQB 350 4MATIC has 4 recalls, all involving the high-voltage battery, with the most serious risk being a battery fire that can occur while the vehicle is parked or being driven.
Three of the four recalls address the same core concern: the high-voltage battery can fail internally and catch fire without warning, whether the vehicle is in motion or sitting still. Prior repair attempts have not fully resolved the issue, which is why multiple campaigns exist for the same defect across overlapping model years. The fourth recall covers a related battery problem where an internal electrical connector can work loose, causing a sudden and unexpected loss of drive power that raises the risk of a crash.
