The 2022 Mercedes-Benz EQB 300 4MATIC has 5 recalls, the most serious being multiple high-voltage battery defects that can cause the vehicle to catch fire while parked or being driven.
The fire risk appears across several recalls tied to the high-voltage battery pack. In some cases the battery can fail internally, generating enough heat to start a fire whether the vehicle is sitting still or in motion. A separate but related battery concern involves an internal electrical connector where a bus bar may be fastened with the wrong screws, which can cause the drive system to cut out without warning, leaving the driver without power in traffic. There is also a front drivetrain concern: a spur gear inside the front axle's electric motor assembly may not have been properly welded, and if that gear fails, the vehicle can roll away when parked, raising the risk of a collision.
