San Diego, California – Mercedes-Benz USA, LLC (MBUSA) has announced a critical recall affecting certain 2022-2023 EQB 250, EQB 300 4MATIC, and EQB 350 4MATIC electric vehicles. The recall stems from a significant safety concern where the high-voltage battery in these models may experience an internal short-circuit within a battery cell, potentially leading to a vehicle fire, whether parked or in motion.

MBUSA has informed vehicle owners that a software update for the battery management system, which would serve as a remedy, is not yet available. In the interim, owners are advised to charge their vehicles only up to 80% capacity to minimize the risk to the battery until the necessary software update can be applied. This precautionary measure is intended to protect the battery and mitigate the fire risk until repairs can be finalized. Following these guidelines, owners do not need to ground their vehicles.

Initial communications to vehicle owners were dispatched on March 28, 2025, alerting them to the associated safety risks. A subsequent notification will be sent when a definitive solution to the issue is developed and ready for implementation.
