The 2023 Mercedes-Benz EQB 300 4MATIC has 4 recalls, all centered on the high-voltage battery, with the most serious risk being a battery fire that can break out while the vehicle is parked or being driven.
Three of the four recalls share the same core danger: the high-voltage battery can fail internally and catch fire without warning, whether the vehicle is sitting in a driveway or moving down the road. Prior repair attempts did not fully resolve the issue, which is why multiple separate campaigns address the same fire risk. The fourth recall involves a related but distinct failure: a connector bar inside the battery pack may be fastened with incorrect screws, causing a poor electrical connection that can cut drive power suddenly and without warning, leaving the vehicle unable to accelerate and raising the risk of a crash, particularly in highway or intersection situations.
