2023 Mercedes-Benz EQB Electrical System Problems

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. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

They’re not replacing my car in a timely manner under the recall and they keep promising to call me and they don’t.

Spoke with MB today and was told that the new battery for this recall would be available in late 2026 and that until then I should only park outside and not charge past 80%. When asked for a loaner car until they fixed the issue I was told no. Afraid to drive and or charge

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

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)

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.

“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)

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.

I was informed of this recall fire risk. And I contacted Mercedes dealership where I got the car. And they informed me that the battery is not available at this time. And to park the vehicle outside. I can’t do this because my charging port is located inside my garage. This is not a safe and the dealership won’t do anything about it.

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)

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

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.

The vehicle is under a safety recall with no permanent fix and is restricted to 80% charging. Even with 8-% charging it is prone to catch fire risks. This reduces usability and raises safety concerns. I
