2023 MERCEDES-BENZ EQB 300 4MATIC Complaints

I am reporting a safety concern regarding my 2023 Mercedes-Benz EQB 300 (VIN: [XXX] ), currently subject to NHTSA Recall 26V073 involving the high-voltage battery. According to NHTSA records and the manufacturer’s recall notice, this vehicle has an urgent safety recall due to a risk of fire caused by a potential internal short circuit in the high-voltage battery. The defect may result in a vehicle fire while driving or parked. The recall was issued around February 9, 2026, and remains unrepaired with no remedy available. The manufacturer has indicated a permanent repair may not be available until approximately December 2026. I have been instructed to limit charging to 80% and to park the vehicle outside due to fire risk, yet I am still expected to operate the vehicle and transport my family. Additionally, I received third-party notification advising that my vehicle should not use DC fast charging due to this safety risk, significantly limiting normal use. Mercedes-Benz USA offered a monetary payment conditioned on waiving all current and future legal rights while the vehicle remains unrepaired. I have not been provided a guaranteed loaner or replacement vehicle, and the dealership has requested return of the loaner. Due to these limitations, I am incurring and expect additional costs and loss of normal vehicle use, including reduced access to charging benefits and potential fuel or charging expenses. This situation requires continued use of a vehicle with a known fire risk, no remedy, and restricted functionality without reliable alternative transportation. I request this be documented as a safety concern involving the defect, delayed remedy, and limitations on safe and normal vehicle operation.

There has been fire hazard due to manufacturer defect (high voltage battery). It has been under recall since Feb 2025, and till date, no battery replacement has been provided despite of fire hazard. The instructions to keep car outside isn't practical to follow for more than year now! It is electric car whose charger is mounted inside garage. Besides there are car theft risk of parking outside. Manufacturer has been providing unreasonable instructions for long duration of time than resolving the problem, particularly when there is recall for fire hazard even when parked or driving. It is life safety issue for entire family and we cannot continue to use this vehicle

The vehicle experienced multiple electrical and safety-related malfunctions while driving. On several occasions the instrument cluster and vehicle screens suddenly went black while the vehicle was in motion, causing loss of critical driving information such as speed and warnings. In another incident the vehicle displayed a “High Voltage Malfunction” warning while driving and the vehicle shut down shortly after. This resulted in a sudden loss of propulsion and created a dangerous situation on the road. The vehicle has also displayed a “Coolant Too Hot – Stop Vehicle” warning which required replacement of the coolant pump at the dealership. In a separate event the vehicle lost battery charge unexpectedly after indicating a full charge and had to be towed to a charging station. The vehicle is also subject to Safety Recall 26V073 involving the high-voltage battery.

Spoke with MB today and was told that the new battery for this recall would be available in late 2026 and that until then I should only park outside and not charge past 80%. When asked for a loaner car until they fixed the issue I was told no. Afraid to drive and or charge
