Summary
The Mercedes-Benz EQB Class has 8 recalls covering 2022-2024 model years, with the most serious being a high-voltage battery defect on 2022 models where internal battery modules can overheat and short circuit, creating a fire risk even while the vehicle is parked and off. This fire risk recall had prior repair attempts that were not fully effective, requiring additional repairs on affected 2022 vehicles. A separate 2022 high-voltage battery issue involves a connection that was not tightened properly, which can cause a sudden loss of drive power while the vehicle is moving.
The 2023 model year has one recall: battery modules that can overheat and short circuit, also posing a fire risk. A prior repair attempt on these 2023 vehicles was found to be incomplete, requiring a second repair.
The 2024 model year has a recall involving the pyro fuse, a component in the high-voltage system that is designed to cut electrical current in a crash. If the housing was not manufactured correctly, the fuse can loosen and damage nearby wiring, causing a loss of drive power. In a crash, the fuse may fail to cut power as intended, or a piece of it can break free and be propelled toward the driver's feet.
Returning to 2022 models, there is also an airbag concern: the B-pillar trim panel can crack when a side curtain airbag deploys in a crash, which can prevent the airbag from inflating correctly and send plastic fragments toward occupants. There is also a powertrain recall on 2022 vehicles related to a parked vehicle rolling away on its own.
