2023 Mercedes Benz EQB 250+ electrical problems

ELECTRICAL SYSTEM

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.

I am the owner/lessee of a 2023 Mercedes-Benz EQB 250+ (VIN: [XXX] ) affected by NHTSA safety recall 26V073 — a high-voltage battery fire risk defect that has failed three separate repair attempts. I am filing this complaint to document Mercedes-Benz USA’s failure to provide an adequate remedy under federal recall regulations. Background: Recall 26V073 was issued three separate times — first as recall 25V050 then 25V894 and finally 26V073. Each prior software remedy failed to resolve the underlying battery defect. Mercedes-Benz has now determined a full battery replacement is required. As of today no replacement battery is available for my specific vehicle VIN [XXX] . Current Situation: As a result of this unresolved recall I have been required to: • Park my vehicle outside and away from structures at all times • Restrict charging to a maximum of 80% capacity • Operate a fire risk vehicle for several months with no remedy available • Absorb $3,000 in home EV charger installation costs now largely unusable due to charging restrictions • Continue paying $22,000 in remaining lease obligations on a vehicle I cannot safely use Federal Compliance Failure: Under 49 CFR 573 Mercedes-Benz USA is required to provide affected owners with a free remedy within a reasonable timeframe. Mercedes-Benz USA has: • Failed to provide a repair — no remedy currently available • Formally declined to repurchase the vehicle • Offered $8,000 in goodwill compensation which does not constitute a remedy under federal recall regulations • Instructed my dealer Crown Eurocars in Pinellas Park Florida not to provide a loaner vehicle or storage assistance despite promising both in a written offer dated April 20 2026 Additional Bad Faith: Mercedes-Benz USA communicated a false claim to MBFS executive resolution team member Caroline stating that I had requested no further contact. I never made this request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Subject: Safety Complaint – 2023 Mercedes-Benz EQB (Active Recall) Reference: CMS Case #XXX Vehicle: 2023 Mercedes-Benz EQB VIN: [XXX] 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. We are concerned that consumers are being left with a vehicle that may be unsafe to operate and cannot be reasonably removed from service. We are requesting review and guidance on: 1. Whether the vehicle is safe to operate 2. Manufacturer responsibility in resolving recall-related limitations 3. Consumer protections in situations where a recalled vehicle cannot be used or traded This situation creates safety, liability, and consumer protection concerns, especially as we must leave the vehicle unattended while traveling internationally.

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

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.

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)

ELECTRICAL SYSTEM

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

NHTSA complaint #11726442 — an unverified report by a vehicle owner.

ELECTRICAL SYSTEM

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 off. 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. NHTSA has formally acknowledged that the defective battery "may fail internally and lead to a vehicle fire while parked or driving," increasing the risk of serious bodily injury or death. I am the parent of toddlers who reside in my household. My vehicle is regularly parked in proximity to my home and family. The risk of a sudden, unannounced vehicle fire — whether in my driveway, garage, or on the road — poses a direct, immediate, and unacceptable threat to the safety and lives of my young children. I cannot continue to operate or park this vehicle without placing my family in danger. Mercedes Benz is coercing me into getting a new Lease contract by using the defective battery as a leverage when in fact they need to take the car back and they are not

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.

Urgent fire risk- 2nd time I have received recall. The wait time for the first was months. The fix on that recall did not remedy the recall and we now received another. I have been unable to charge at home with a level 2 charger out of fear of catching fire as my port is attached to my home. No remedy is available other than a continuous wait for possible replacement of battery. This is a huge safety risk and I feel unsafe operating this vehicle. Operating my vehicle with my children in the car has caused me a great deal of fear and anxiety. The car should be purchased back by the dealer.

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)

Mercedes built the car with a faulty battery and now they want to provide an "update" to the car that makes it worse: reduced battery life and slower charging times. So I have to choose between only charging my car to 80% or taking their update which makes my car worse. How can the NHTSA allow that to be the solution to the problem?

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. The problem has not been repaired, and I am left with a vehicle that is potentially unsafe to drive. I am requesting a formal investigation and resolution, including the option of a vehicle buyback.
