Vehicle: 2023 Mercedes-Benz EQB 350 4MATIC Recall Reference: NHTSA Campaign #26V073 / High-Voltage Battery Fire Hazard My vehicle is subject to an active safety recall concerning internal high-voltage battery failure that poses a direct risk of a vehicle fire while driving or parked. The manufacturer has instructed owners to limit battery charging to a maximum of 80% and to park the vehicle outside away from structures due to fire hazards. On October 20, 2026, Mercedes-Benz USA Customer Retention Management formally notified me in writing that the estimated remedy/parts availability date for this high-voltage battery replacement is December 2026. Being forced to operate a vehicle with an active battery fire risk for over two years without a fix severely compromises the safety of my household, neighbors, and workplace. Furthermore, Mercedes-Benz USA has formally declined my request for a vehicle repurchase/buyback. I am filing this complaint to document the extreme safety risk and the unreasonable delay in providing a safety remedy.

ELECTRICAL SYSTEM, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS
My 2023 Mercedes-Benz EQB250 (VIN: [XXX]) 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 #[XXX]) 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. They are actively attempting to force a consumer to either pay $5,800 out-of-pocket for a warrantied high-voltage component or drive a compromised EV powertrain that violates the manufacturer's own outdoor parking safety mandates, as the owner resides in an apartment complex with an enclosed underground garage.

VISIBILITY/WIPER
The rear liftgate glass (backlite) of the vehicle shattered spontaneously while the vehicle was parked and unoccupied inside a closed parking garage on 09/30/2026. There was no break-in, no impact, no vandalism, and no warning lamps, messages, or other symptoms prior to the failure. The entire tempered-glass pane crazed and partially collapsed with no visible point of impact, consistent with spontaneous tempered-glass failure caused by a nickel sulfide inclusion, a documented glass manufacturing defect. The failed glass is being replaced through the owner's insurance by Safelite AutoGlass. The selling dealer, Mercedes of Seattle, declined to inspect the vehicle and stated they had never heard of such a failure; the problem has not been inspected or confirmed by the manufacturer, a dealer, or an independent service center. Although no one was injured because the vehicle was unoccupied, the same failure while the vehicle is occupied or in motion could shower occupants with glass fragments and eliminate rearward visibility. The complainant asks NHTSA to investigate whether this indicates a glass manufacturing defect trend.

My vehicle battery overheated. The dealership was unable to identify the cause. I have since learned there is a battery recall on this make and model, and I believe the recall needs to be expanded to include my vehicle and the overheating was likely caused by the battery failing.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
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.”

BATTER RECALL FIRE SAFETY: I have a 2023 Mercedes-Benz EQB 250+ affected by NHTSA safety recall 26V073. Mercedes has acknowledged that the high-voltage battery can fail internally and cause a fire. I’m instructed to charge only to 80% and park outside away from structures, and Mercedes’ latest remedy requires replacement of the entire high-voltage battery. This is already a low range vehicle and limiting to max 140 miles on interstate before having to charge 45 minutes is a nightmare. I need to drive between states for work and this is just simply not feasible after doing so for months without a solution. The first recall was March 2025 with no fix.

POWER TRAIN, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
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 NHTSA 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 NHTSA 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 NHTSA 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 NHTSA 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.

The battery in this car can catch fire at any time while parked. The dealership would not take the car to inspect, repair or replace the battery because there is no remedy available at this time. The recall information go back to January 2026 with no remedy or resolution available period. Instructions say I can charge it only up to 80%. I have to make adjustments to my daily routine. Instructions say I have to park it away from buildings. This car is a serious safety hazard for humans and buildings.

FUEL/PROPULSION SYSTEM
My 2023 Mercedes-Benz EQB is included in the high-voltage battery fire recall (NHTSA campaign 26V073). The recall states the battery cells may fail internally at a high state of charge, causing an internal short circuit and a potential fire whether the vehicle is parked or being driven, with no advance warning while parked. As interim safety measures, Mercedes-Benz instructed me to limit charging to 80% and to park the vehicle outdoors, away from structures. These restrictions materially impair the vehicle's use: I cannot charge to full capacity and cannot park in my garage due to the fire risk to my home. The permanent remedy is replacement of the high-voltage battery pack. However, my Mercedes-Benz dealer has informed me that the replacement parts will not be available until 2027. That means I am being asked to operate a vehicle with an acknowledged fire risk, under charging and parking restrictions, for roughly 18 months or more, with no remedy currently available. I am requesting that NHTSA document this lack of an available remedy and the extended timeline. A delay of this length leaves owners exposed to the safety defect the recall was issued to address.
