My vehicle contains a defective high-voltage lithium-ion battery that is subject to internal short circuits caused by deviations in the battery supplier's production process. According to NHTSA and Mercedes-Benz's own recall documentation, an internal short circuit in a battery cell can trigger a thermal event - that is, a vehicle fire - whether the vehicle is parked or being driven. Critically, NHTSA has specifically warned that there may be no external warning or dashboard indicator when the thermal event occurs while the vehicle is parked and shut o . This defect is not theoretical. Mercedes-Benz first became aware of vehicle fires caused by this same battery defect through reports of confirmed fire incidents in other markets. …

I am submitting this complaint regarding an active fire risk recall on my Mercedes Benz EQB and MBUSA's refusal to provide a safety remedy. My vehicle was previously placed under a no drive instruction due to the fire risk recall. MBUSA attempted a remedy, but that remedy failed, and the safety impairment remains. Despite this, MBUSA Customer Care has declined to confirm or deny a safety related repurchase and has stated that their goodwill options (loaner, rental, storage, and cash considerations) are their final position. These goodwill measures do not address the underlying safety defect. I have repeatedly asked MBUSA to confirm whether they are denying a safety related repurchase under the active fire risk recall, the prior no drive instruction, the failed remedy attempt, and the ongoing safety impairment. …

Subject: Safety Complaint - 2023 Mercedes-Benz EQB (Active Recall) Reference: CMS Case #[redacted] Vehicle: 2023 Mercedes-Benz EQB VIN: [redacted] I am filing a safety complaint regarding an active recall on my vehicle and the lack of a clear, safe resolution. The vehicle is currently under an active safety recall, and we have been advised it may not be safe to operate under certain conditions. At the same time, the dealership has informed us that the vehicle cannot be traded in due to the recall. This has left us in a position where: * We may not be able to safely drive the vehicle * We cannot trade or dispose of the vehicle * We have not been given clear guidance on safe use or storage Mercedes-Benz USA (CMS Case #21602523) has declined a repurchase and offered only partial goodwill compensation without providing a clear, actionable solution. …

My 2023 Mercedes-Benz EQB250 (VIN: [redacted]) is currently sidelined at Mercedes-Benz of Pompano with a dangerous High-Voltage system failure that causes an immediate cascade error of the Electronic Stability Program (ESP) and vehicle braking systems. The technician verified the codes match Mercedes Service Bulletin LI42.45-P-079407 for an HV DC/DC Converter defect and matched my serial number to the bad batch. The vehicle simultaneously carries an active Federal Safety Recall for an internal High-Voltage Battery Pack explosion/fire risk (NHTSA Campaign 26V073). Mercedes-Benz USA Corporate (Case #[redacted]) and Service Director Hayden Smith are actively refusing to honor the 8-year/100,000-mile High-Voltage warranty on this converter. Furthermore, the dealership is threatening to charge me 'late fees' to strip away alternative loaner transportation. …

On February 3, 2025, a recall (NHTSA Recall No. 25V050 / Manufacturer Recall No. 2025040005) was issued for my 2023 Mercedes-Benz EQB 250+ due to a defect involving the high-voltage battery that may cause a fire. I brought the vehicle to the dealership shortly after the recall was announced. The service department informed me that no remedy is currently available and they do not have a timeline for when one will be. This unresolved recall places my safety-and the safety of others-at risk, as the vehicle could potentially catch fire without warning. Despite contacting the dealership and waiting several months, I have received no updates, no repairs, and no temporary accommodations. The vehicle has not shown specific warning lights or messages, but the issue is acknowledged by the manufacturer as a fire risk. …

THere is a global recall of the 2023 EQB 250 vehicle due to an unfixed battery issue. (It is the second recall for the same issue fur my vehicle). However, the manufacturer has not sent me any warning about the latest battery recall (critical risk of fire). The dealer is only engaging over voice calls and refusing to put any acknowledgement of the recall or the risk in writing. There is no remedy in sight, and they are unable to exchange the impacted battery either. The utility of vehicle has decreased significantly, and is a real risk for people like me living in a high-fire-hazard zone (Oakland Hills, with history of the entire neighborhood burning down)

We purchased a 2023 Mercedes EQB (EV) 2 years ago. The car is part of a recall in which we are advised to not park near other cars and not charge at home. Thus making the car essentially not useable unless we take the risk. We are driving it, knowing that we could catch fire. We are parking it and charging it in our garage, knowing it could catch fire. We have no choice as Mercedes has not offered any loaner or rental option so we can park this car until the recall or buyback is complete. Mercedes has estimated December 2026 when a solution will be available and March 2027 to when we can expect it to be completed.

February 2026, our vehicle was recalled for the Battery Issue. We contacted Mercedes Benz USA LLC, several several times ,we filed a claim, they said it would be for a Buy Back, we can not get anyone to call us back to resolve this issue, we contacted the dealer that we purchased the vehicle from and they will not call us back at all. Meanwhile we have received emails from the Charging Station Companies that we can no longer charge our vehicle with their companies due to the recall on the Battery, per the recall they reviewed / received, so we are stuck with a car that we can not charge / drive. We need help.
