What the fix does
The 2023 Mercedes-Benz EQB 350 4MATIC has 4 recalls, all centered on the high-voltage battery, with the most serious risk being a battery fire that can break out whether the vehicle is parked or in motion.
Three of the four recalls involve the high-voltage battery failing internally in a way that can ignite a fire with no warning, whether the car is sitting in a garage or being driven on the road. These are separate filings covering overlapping model year ranges, but the real-world danger is the same: an internal battery failure that produces heat and fire without any obvious prior symptom for the driver. The fourth recall involves a different battery fault where a connector inside the battery pack can work loose, cutting drive power to the motors without warning. When that happens, the vehicle can lose forward thrust unexpectedly in traffic, leaving the driver without the ability to accelerate and raising the risk of being struck from behind or losing control in a merge or highway situation.
