Initial vehicle failure started January 22. 2026 with an initial recall software attempt to correct the battery safety. My car then became undriveable. The Safety Fire Risk recall started February 9, 2026, there is still no remedy and direction from the manufacturer due to the fire risk are to PARK OUTSIDE and not charge above 80%. I am coming up on 9 months and no parts are available to correct this manufacture defect. THIS IS NOT A TIMELY REMEDY. I am unable to use the vehicle as intended and designed as most places I frequent including work have parking garages. Mercedes Benz has placed the liability on me for their inferior product that they are unable to fix to date. The car is deteriorating from the required outdoor parking only. I have a horrible odor from the HVAC system that has been disinfected 3 times already and still smells. All 4 tires have prematurely dry rotted to the point the dealer recommends replacement. Paint and molding fade. Most recently rodents got up in the undercarriage and chewed wires which control the right side door locks. To date all of these items remail unrepaired and only the HVAC odor was attempted under warranty, the others I was told are not covered. I always park my vehicle in the garage to avoid all of these items and many more which I expect to eventually happen as well.

I own a 2023 Mercedes-Benz EQB 300 4MATIC. My vehicle has multiple unresolved high-voltage battery safety recalls. Recall 25V050/MBUSA campaign 2025040005 concerns a potential internal battery-cell short circuit and fire risk. I had the BMS software update performed, but Mercedes later issued recall 26V073 because the software remedy was not considered sufficient for all affected vehicles. Recall 26V073 requires complete high-voltage battery replacement. Until that repair is completed, Mercedes instructs owners to park outside and away from structures and limit charging to 80%. My vehicle also shows recall 25V487/MBUSA campaign 2025070009 as pending. This recall concerns a battery busbar connection that could cause sudden loss of propulsion without warning, increasing the risk of a crash. Despite the ongoing fire-risk and loss-of-propulsion concerns, I have not been provided a firm, VIN-specific date for the battery replacement. The safety restrictions significantly limit my ability to use and safely park the vehicle. I am concerned that the permanent remedy remains unavailable while I continue to make lease payments.

I am the owner of a 2023 Mercedes-Benz EQB that has been identified as being affected by the current high-voltage battery safety recall. I recently contacted my authorized Mercedes-Benz dealer regarding the recall and was informed that the recall is currently pending for my vehicle and that the permanent remedy is not expected to begin until approximately December. I understand that the interim safety guidance associated with this recall includes limiting charging to 80% and parking the vehicle outside and away from structures. I have a significant concern regarding the parking instruction. My vehicle is normally parked in an attached garage at my condominium. The garage is connected to my residence, and my HOA does not permit me to park the vehicle outside. Therefore, I do not have a practical way to comply with the instruction to park outside and away from structures. I specifically raised this issue with the service department. I was told verbally that I could continue parking the vehicle in my garage “at my discretion.”

The affected component is the high-voltage traction battery and related battery management and bus-bar connection systems. My vehicle is available for inspection upon request. I am reporting a safety concern because my vehicle is subject to the federal safety agency Recall 25V050, which identifies a risk that the high-voltage battery could fail internally and cause a fire while parked or driving. It is also subject to the federal safety agency Recall 25V487, which identifies a defect involving the high-voltage battery bus-bar connection that may cause a sudden loss of drive power without warning. A battery fire could endanger vehicle occupants and people or property near a parked vehicle. A sudden loss of propulsion while driving could increase the risk of a crash. I have not personally experienced a vehicle fire or a sudden loss of drive power. However, I am being asked to continue operating and making lease payments on a vehicle with identified high-voltage battery safety defects and no completed effective remedy available for my vehicle. The currently available guidance limits charging to 80%, which reduces the vehicle’s usable range and practical value. The vehicle’s recall status has been confirmed through the federal safety agency and Mercedes-Benz recall information. To my knowledge, no dealer repair has been completed that eliminates these safety concerns. The vehicle has not been inspected by police, insurance representatives, or an independent service center in connection with an incident because no crash, fire, or loss-of-power event has occurred. Before any failure, I have not observed a warning lamp, warning message, or other battery-related symptom. My concern is that Recall 25V487 describes a potential sudden loss of drive power without warning, and Recall 25V050 identifies a potential battery-fire risk, including while the vehicle is parked.

Vehicle: 2023 Mercedes‑Benz EQB VIN: [XXX] MBUSA Case #: XXX the federal safety agency Recall #: 26V073000 Mercedes‑Benz USA has mishandled recall 26V073000 (fire hazard) and left me without transportation. I was told the vehicle is unsafe to drive, which has caused significant anxiety, panic attacks, and ongoing stress because I have no safe way to commute or manage daily responsibilities. MBUSA repeatedly promised a loaner vehicle, but the dealership stated they were never contacted, had no instructions, and had no loaner available. MBUSA later said I could receive a rental car “upon eligible dealership,” but they did not specify which dealership, and after calling multiple Mercedes‑Benz locations, all confirmed they had no information, no authorization, and no process for rental reimbursement or recall support. MBUSA has provided conflicting and misleading information, failed to coordinate with dealerships, and failed to provide transportation during a fire‑hazard recall. This has caused loss of use, mental distress, and safety exposure. I request investigation into MBUSA for failure to properly administer recall 26V073000, failure to provide transportation during a safety recall, and misrepresentation of recall remedies.

There is a recall associated with this model that causes catastrophic stoppage without any ability to drive. My vehicle VIN does not have a recall according to your site. Despite this, my vehicle catastrophically stopped multiple times. It was repaired at least three times and still stopped in the middle of the highway. My partner and I were stopped on I-85S with no ability to move, honk, put on hazards. Cars zoomed past at full speed. I called 911 as we braced for impact. We are lucky to be alive and now suffer from severe trauma. They eventually closed the entire highway and dragged the vehicle to the shoulder almost 30 min later. Mbusa was aware of this defect before rejecting my lemon law claim, but my vehicle was not included apparently. I feel more investigation is needed because it seems very likely my vehicle should be included in the recall. I appreciate your attention to this matter.
