2023 Mercedes-Benz EQB 300 4MATIC Owner Complaints

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.

Incident

Sep 16, 2026

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.”

Incident

Aug 31, 2026

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.

Incident

Apr 20, 2026

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.

I am reporting a significant safety concern regarding my 2023 Mercedes-Benz EQB. While my specific VIN has not been included in the current high-voltage battery fire risk recall (NHTSA Campaign 26V073000), my vehicle is a 2023 model that shares the identical high-voltage battery architecture, manufacturing window, and platform design as the approximately 12,000 EQB vehicles officially recalled due to an internal defect that causes sudden, unpredictable battery fires. As a vehicle owner, I am now experiencing deep, well-founded anxiety regarding the safety of this vehicle. Due to the proximity of my vehicle's design to those definitively identified as defective, I have lost confidence in the vehicle's safe operation. I can no longer park this vehicle in an enclosed garage or charge it with confidence, effectively limiting my ability to utilize the vehicle as intended. I am filing this report to formally document my concern that this safety defect may be more widespread than the current recall population suggests, posing an unreasonable risk to the safety of myself and the public.

MB recall is since Feb 2026 and they neither ready to fix it not ready to provide a proper compensation . The vehicle is currently unusable for the following reasons: 1. Safety Catch-22 (Fire vs. Theft): Due to the fire hazard associated with the current battery recall, I cannot safely charge or store the vehicle in my garage. However, the local Township Police have explicitly advised against keeping the car outside due to high theft risks in the area. Mercedes-Benz has essentially provided a vehicle that is neither safe to keep indoors nor secure to keep outdoors. 2. Home Charging Restrictions: I typically charge the vehicle at night; however, the current recall guidelines necessitate monitoring the charge to ensure it does not exceed 80%. I have no practical way to monitor this throughout the night, making home charging a safety liability. Public Infrastructure Failure: The EVgo charging network has blocked the Mercedes-Benz EQB model from their network due to these safety concerns. This further eliminates my ability to use the vehicle for standard commuting or travel. 3. Lack of Support and Loaner Access: Despite these documented safety risks, my local Mercedes-Benz dealer has refused to provide a loaner vehicle, stating they are awaiting specific instructions from corporate. This leaves me without a safe mode of transportation while I continue to pay for a vehicle I cannot use. 4. Financial Loss: I am currently paying monthly insurance premiums of approx $300, car payments of $529, and have recently invested in new tires for a vehicle (~$1200) that is sitting idle. I am incurring the full cost of ownership for a product that fails to meet basic safety and utility standards. I need NHTSA to help me here as MB is not able to honor its federal mandate

I received an Important Safety Recall notice (NHTSA Recall ID: 26V073) from Mercedes-Benz USA in March 2026 regarding my 2024 EQB (VIN: [XXX] ). The notice states that the high-voltage battery may fail due to an internal short circuit, potentially causing a vehicle fire while parked or driving. No incident has occurred. This complaint is filed because no remedy is available and no timeline has been provided by the manufacturer. Mercedes-Benz has advised owners to limit charging to 80% and to park outside while awaiting battery replacement parts. This interim guidance creates an additional hardship: my vehicle is garaged in ZIP code 98119 (Seattle, WA), where property crime is documented at over 50% above the national average. The manufacturer's guidance forces me to expose a $55,000+ vehicle to elevated theft and vandalism risk indefinitely, through no fault of my own. I am requesting NHTSA pressure Mercedes-Benz to accelerate parts availability and provide affected owners with a loaner vehicle or covered parking reimbursement until the remedy is performed.

I am requesting that my 2023 Mercedes‑Benz EQB be added to the recall associated with high‑voltage battery safety issues. My vehicle is exhibiting the same symptoms described in NHTSA Recall No. 26V073000, but my VIN is not currently included. I was instructed not to fully charge the vehicle and warned that it may pose a fire hazard if parked inside my garage. These warnings indicate a serious safety defect involving the high‑voltage battery system. The vehicle cannot be safely stored at my residence, and its normal operation is substantially impaired. The safety risk is significant: the vehicle may overheat or catch fire during charging or while parked. This creates a danger to occupants, nearby structures, and the public. The problem has been acknowledged by the manufacturer in communications but no permanent repair is available. The symptoms and restrictions match those described in the existing recall. I am requesting that NHTSA investigate and determine whether my vehicle should be added to the affected VIN list, as it appears to suffer from the same high‑voltage battery defect and presents the same safety hazards.

I received an official recall notice from Mercedes-Benz regarding my EQB due to a defect involving the high-voltage battery system. According to the recall notice, the battery may experience an internal failure that could potentially result in a fire while the vehicle is either parked or being driven. Mercedes-Benz has also advised owners to limit charging and park the vehicle outside due to the severity of the safety risk. At this time, Mercedes-Benz has not provided a permanent repair remedy or battery replacement. Because I no longer feel safe driving or storing the vehicle, I have left it at the dealership and am currently using a loaner vehicle while attempting to reach a fair and reasonable resolution with Mercedes-Benz. Given the serious safety concerns associated with this recall and the lack of an available repair, I do not believe the current offer being presented by Mercedes-Benz adequately resolves the situation. During my first conversation with Mercedes, I was clearly told that I had two options: trade into another lease or have Mercedes repurchase the vehicle at no cost to me. At no point during that initial conversation was I told that repurchase was unlikely or subject to higher-level approval. $7,500 does not address the core issue, which is that I am still left in a lease for a vehicle I do not feel safe driving or storing. This is fundamentally a safety and usability issue, not simply a financial inconvenience. I am simply asking Mercedes to stand behind its product and provide a reasonable resolution for a leased vehicle that has been deemed subject to a serious fire-risk recall without a current repair remedy.

Compounded Electrical Failures In addition to the battery defect, this specific vehicle has exhibited recurring electrical malfunctions, including: Total failure of the backup cameras and parking sensors. Intermittent failure of the HVAC system (Air Conditioning), critical in the Florida climate. Erratic Autonomous Braking: The vehicle has repeatedly engaged emergency braking while reversing without cause, nearly resulting in multiple collisions. Diminished Utility and Breach of Lease Expectations The "interim" instructions provided by Mercedes-Benz have fundamentally altered the vehicle’s functionality from the terms established at the start of my lease: Charge Limitation: The "MUST NOT exceed 80%" mandate reduces the vehicle's range and utility, failing to meet the deliverable of a fully functional EV. Parking Restrictions: The requirement to park outside for fear of a garage fire is an unreasonable burden that violates the expected use of a luxury vehicle. Failure to Remedy within a Reasonable Time (49 U.S.C. § 30120) Under the National Traffic and Motor Vehicle Safety Act, specifically 49 U.S.C. § 30120(c)(2), a manufacturer’s failure to remedy a defect within 60 days of a vehicle being presented or a notice being issued constitutes prima facie evidence of a failure to remedy within a reasonable time. The notice for Recall 26V073 was issued in March 2026. As of today, May 11, 2026, more than 60 days have passed without an actionable remedy or a definitive timeline for repair. There have been ZERO warnings or indications of the above mentioned.

Dear NHTSA Safety Team, I am submitting a formal safety-related complaint regarding my 2023 Mercedes-Benz EQB 250, which is currently under an active high-voltage battery recall. The recall imposes significant safety restrictions, including an 80% charging limit, a requirement to park the vehicle outside due to fire risk, and the inability to safely charge the vehicle at home. Additionally, I have been advised by my dealership that DC fast charging should not be used, further limiting the vehicle’s usability. Mercedes-Benz has informed me that the remedy requires a full high-voltage battery replacement, which may take many months (until at least December). In the meantime, the vehicle is not usable as a daily vehicle due to the combined safety and charging restrictions. I have attempted to work with Mercedes-Benz USA to obtain an appropriate remedy for this loss of use, but I have been told that only minimal options are available, and my request for executive-level review has been denied. I am requesting NHTSA’s assistance in reviewing this matter as a safety-related loss-of-use issue. The current restrictions materially affect my ability to safely operate and maintain the vehicle. Thank you for your attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident

Apr 21, 2026

COMPONENT/SYSTEM: High-voltage battery system (traction battery). The vehicle is subject to a manufacturer recall for risk of internal short circuit and potential thermal event. The vehicle and battery are available for inspection upon request. SAFETY RISK: According to the manufacturer and dealer, the defect presents a risk of battery fire, including while the vehicle is parked and not in operation. As a result, the manufacturer has instructed safety precautions, including limiting charging to no more than 80% and parking the vehicle outdoors and away from structures. These precautions materially limit driving range and require the vehicle to be parked away from the residence, which increases risk exposure to occupants, visitors, and surrounding property. REPRODUCTION/CONFIRMATION: The defect has been confirmed by the manufacturer through a formal recall applicable to this vehicle. The dealer has acknowledged the recall and the associated safety instructions. INSPECTIONS: There has been no individualized inspection specific to this vehicle because the issue is a known, manufacturer-identified defect affecting recalled vehicles of this model. The condition and risk have been acknowledged by both the manufacturer and dealer. WARNINGS/SYMPTOMS: There were no prior warning lights, messages, or observable symptoms before receiving notice of the recall. The safety issue was not detectable to the driver absent the manufacturer’s notification. REPAIR STATUS/TIMING: The manufacturer has advised that replacement batteries are not expected to be available for several months (estimated beginning December 2026 or later). In the interim, the vehicle must continue to be operated under the above safety restrictions, while customer must still bear the known, significant risk of fire until then.

The high-voltage battery cells in my vehicle, supplied by Farasis Energy, are prone to internal short circuits that can cause thermal runaway and vehicle fire. This defect poses a serious risk of fire while the vehicle is parked or in operation. Mercedes-Benz USA has acknowledged this defect through three separate recall campaigns (25V050, 25V894, and 26V073). The first two remedies — software updates — failed to prevent fires, including post-repair fires reported in Europe. Mercedes-Benz subsequently committed to full battery replacement as the only effective fix, but has not made repair scheduling available until approximately December 30, 2026. In the interim, Mercedes-Benz has instructed owners to: (1) park and charge exclusively outdoors, (2) limit charging to 80% of battery capacity. These extraordinary restrictions confirm that the vehicle remains a fire risk and is currently unfit for safe normal use.

I am writing to formally notify the National Highway Traffic Safety Administration (NHTSA) that Mercedes-Benz USA has failed to remedy a known safety defect within a reasonable amount of time, pursuant to 49 U.S.C. § 30120. This notification is submitted in relation to the recall issued under the National Traffic and Motor Vehicle Safety Act regarding the high-voltage battery cells in the 2023 EQB. The manufacturer has acknowledged that an internal short circuit within the battery cells may lead to a vehicle fire while driving or parked. Despite this, a timely and effective remedy has not been provided, leaving me to manage the following severe burdens: • Safety and Psychological Distress: Every time I operate this vehicle, I experience significant anxiety. My primary concern is the safety of my grandchildren; I am constantly haunted by the question of whether I could safely extricate them from the vehicle should it ignite while in motion. • Property and Liability Concerns: I am currently forced to park the vehicle away from other cars and structures to mitigate the risk of a conflagration. I am deeply concerned about my legal and financial obligations should the vehicle ignite and cause damage to third-party property or result in personal injury. • Diminished Performance: The vehicle currently exhibits a decreased mileage range, failing to meet the performance specifications promised at the time of lease. • Breach of Lease Terms: I am required to make full monthly lease payments as per my agreement. However, Mercedes-Benz is failing to uphold their portion of the contract by providing a vehicle that is safe, functional, and fit for its intended purpose. I request that the NHTSA investigate Mercedes-Benz’s delay in providing a definitive remedy and hold the manufacturer accountable for the loss of use and the inherent dangers posed by this defect. A car that "potentially could ignite into flames" at any moment is not a "remedied" vehicle under the law.

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.
