Mercedes-Benz is recalling the all-electric version of its GLB subcompact crossover, the EQB, over a serious fire hazard related to a manufacturer defect in the vehicle’s high-tension battery. Mercedes says that the problem only affects vehicles built between the 2022 and 2024 model years, as

have had the problem corrected at the factory. If you own a Mercedes EQB electric vehicle (EV), here’s everything you need to know about this problem and what you should do next.

This is one of the rare cases where I’d recommend getting the gas model instead.
The EQB’s Battery Modules Could Overheat While Charging
According to official recall descriptions from the NHTSA and Transport Canada on the matter, a defect inside the battery itself could cause its modules to overheat and short circuit while being charged, leading to a potential fire. This problem has been reported in the entire EQB lineup, including the EQB 250+, EQB 300 and EQB 350. In the U.S., the NHTSA estimates that 7,362 vehicles are potentially affected, while in Canada, we’re talking about 632 units that could be plagued with this safety hazard.
Both government bodies recommend all owners to limit their maximum charge to 80-percent until further notice and, if possible, to avoid charging their vehicle inside a closed area like a garage. If you are the owner of an EQB, it’s preferable to charge your vehicle outside, and as far away from your home as possible.
What To Do If You Own A Mercedes EQB?
Mercedes-Benz says that a letter will be sent to owners of affected vehicles on April 1, 2025. The letter will instruct owners to bring their vehicles to their local Mercedes-Benz dealership where the battery management system software will be updated free of charge. As I write this, there have been no injuries or fatalities related to this defect, and the risk of a fire breaking out in your car remains low. This recall acts mostly as a safety precaution, but it remains highly recommended to have it done.
