“My 2023 Mercedes-Benz EQB 350 is subject to NHTSA recall 26V073 involving a high-voltage battery defect that may cause a fire. The manufacturer has instructed me to limit charging to 80% and to park the vehicle outside due to fire risk. This significantly reduces the vehicle’s usable range and creates safety concerns. Due to this 80% charging limitation, the vehicle no longer provides sufficient range for my daily commute and cannot be reliably used for its intended purpose. The manufacturer has stated that the permanent remedy (battery replacement) is not yet available, with an estimated timeline extending into December 2026. I opened a case with Mercedes-Benz on April 3, 2026 (Case #[XXX]), and as of today no case manager has been assigned despite multiple follow-ups. As a result, I am operating a vehicle with a known safety defect that cannot be repaired and cannot be used as intended. This represents both a safety risk and a failure to provide a timely remedy for a safety recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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 purchased a Mercedes EQB 250+ (2023) in December 2025 from W.I. Simonson Mercedes-Benz in Santa Monica, CA(certified dealership). In April 2026, I discovered a recall affecting certain EQB vehicles through a Facebook forum. After entering our VIN into the official recall database, we confirmed that our vehicle is subject to a recall issued in February 2026. We did not receive any notification (mail, email, or otherwise) from either the dealership or Mercedes-Benz regarding this recall. I contacted the dealership’s Service Department to inquire about the recall and repair options. I was informed that: •The required parts are currently unavailable •Parts are not expected until approximately December 2026 •I should contact Mercedes-Benz corporate for further assistance I contacted Mercedes-Benz customer support and provided my personal details (name, phone number, VIN, address). I explained that: •The recall involves a serious safety concern (potential fire risk) •I have an infant and cannot safely operate the vehicle •I require a loaner vehicle or alternative transportation immediately The representative: •Confirmed that a case was opened •Advised that a follow-up would occur within 7 days I contacted the dealership again to request a loaner vehicle. I was advised that: •Loaner vehicles are only provided when a vehicle is actively undergoing service •Since parts are unavailable, the vehicle cannot be taken in for service Therefore, a loaner vehicle cannot be provided After escalation, a Service Advisor confirmed: •The dealership cannot provide a loaner under these circumstances •Resolution must be pursued directly with Mercedes-Benz corporate Corporate may potentially offer: •A loaner vehicle •A vehicle buyback The vehicle is not safe to operate, leaving me without reliable transportation No loaner vehicle or alternative transportation has been provided Responsibility has been deferred between the dealership and manufacturer

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.

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. They have refused to answer this question and have stated there is no further escalation within their department. I am requesting NHTSA’s assistance in reviewing this matter, as the manufacturer has not provided a safety remedy and is refusing to address the safety‑related repurchase question. Thank you for your attention to this safety concern. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was informed that many cars of my make, and model have been recall they will not take into consideration the fact that it’s a safety concern for me now even though I’ve seat didn’t ask questions in regards to this car I know that this car in particular has had over 12,000 recalls for cars between 2022 and 2024 and I’ve asked the dealership to go ahead and see if they can assure me that my car‘s not gonna have a problem in the future and they can’t assure me they just told me to charge my car at 80% away from the house which is a little bit impossible since I do have my charging method next to our home I’ve asked for Goodwill. I’ve asked questions to see if they can help us out, but it feels like they really don’t care about the concern. They’re more worry about the value of the car, but at this point, my husband and I are super disappointed because our car has also depreciated a lot because of this

There has been fire hazard due to manufacturer defect (high voltage battery). It has been under recall since Feb 2025, and till date, no battery replacement has been provided despite of fire hazard. The instructions to keep car outside isn't practical to follow for more than year now! It is electric car whose charger is mounted inside garage. Besides there are car theft risk of parking outside. Manufacturer has been providing unreasonable instructions for long duration of time than resolving the problem, particularly when there is recall for fire hazard even when parked or driving. It is life safety issue for entire family and we cannot continue to use this vehicle

The vehicle experienced multiple electrical and safety-related malfunctions while driving. On several occasions the instrument cluster and vehicle screens suddenly went black while the vehicle was in motion, causing loss of critical driving information such as speed and warnings. In another incident the vehicle displayed a “High Voltage Malfunction” warning while driving and the vehicle shut down shortly after. This resulted in a sudden loss of propulsion and created a dangerous situation on the road. The vehicle has also displayed a “Coolant Too Hot – Stop Vehicle” warning which required replacement of the coolant pump at the dealership. In a separate event the vehicle lost battery charge unexpectedly after indicating a full charge and had to be towed to a charging station. The vehicle is also subject to Safety Recall 26V073 involving the high-voltage battery. According to the recall notice, the battery may fail due to an internal short circuit which could lead to a vehicle fire while parked or driving. The manufacturer currently does not have a repair available and advises owners to limit the battery charge to 80% and park the vehicle outside when not in use due to the potential fire risk. These repeated failures combined with the unresolved safety recall raise serious concerns about the safety and reliability of the vehicle. The issues began around September 2024 and have continued through multiple repair visits into March 2026.

The high-voltage battery system in my 2023 Mercedes-Benz EQB 250+ is subject to NHTSA Recall 26V-073, the third recall issued for the same battery cell defect. The manufacturer has acknowledged that the two prior recall remedies (25V-050 and 25V-894, both software-based Battery Management System updates) were "failed remedies" that did not eliminate the risk of internal short circuit and thermal event (fire). The manufacturer has instructed all affected owners to park the vehicle outdoors and away from any structure and to limit charging to 80% state of charge until a full battery pack replacement can be performed. The battery replacement parts are not expected to be available until approximately December 2026 — roughly 9 months from the date of this complaint. These restrictions create a significant safety risk and loss of use for my household. I have a newborn infant and no viable outdoor parking option. The vehicle cannot be safely parked in my garage per the manufacturer's own instructions due to fire risk. My spouse cannot safely park away from our residence and transport an infant on foot. The vehicle was previously brought to an authorized Mercedes-Benz dealership for prior recall-related service. The underlying battery cell defect — attributed by the manufacturer to deviations in the supplier (Farasis Energy) production process — has not been resolved despite multiple repair attempts. The high-voltage battery is available for inspection upon request. No warning lamps or messages appeared prior to the recall notification. The defect is an internal cell-level issue that may cause thermal runaway without warning, whether the vehicle is parked, charging, or in operation. Two confirmed fire incidents among affected vehicles in the United States have been reported to NHTSA. I am requesting that this complaint be documented to support the record of this recurring, unresolved safety defect affecting approximately 11
