Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023-2024 EQB 250+, 2022-2024 EQB 300 4MATIC, and EQB 350 4MATIC vehicles. The high voltage battery may fail internally and lead to a vehicle fire while parked or driving.
Although I have not experienced safety issues myself, this exact model+year combination has been recalled more than once: 2024 Mercedes EQB 300 4matic, and when I searched by my VIN it shows recall. Iâm very concerned if my car is mistakenly not included - what if it has battery issue/fire risk but I am not aware? This poses huge safety risk on day to day driving. I request an investigation on this particular VIN and reasons of why it is not in the recall list despite all infos match.
On [XXX] at [XXX], while I was slowly moving my car into a parking spot, the vehicle suddenly stopped for a brief moment and then, within a second, unexpectedly accelerated forward without any input from me. The car jumped onto the pathway and collided with the glass door of the property located at [XXX] ". I attempted to control the car using the brakes immediately, but the vehicle was not responding and remained out of control. There were no alert sounds or warnings before or during the incident. The vehicle finally stopped only after hitting the glass door. I strongly believe this was caused by a software or system bug, as the sudden acceleration occurred without my intervention. Please investigate this issue thoroughly, as it raises serious safety concerns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
