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

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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

The car is subject to a NHTSA recall 26V073. Mercedes has scheduled warranty repair for December 31, 2026, or more than 9 months from now. Our dealer advises that the scheduled date is just a holding date; there is no assurance that the repair will occur on or before that date. Mercedes has also said in writing that "the battery replacement remedy is not yet available" and that we should complain to NHTSA if Mercedes does not fix this problem in a reasonable time. In the meantime, we are instructed to park the car outside and not to charge it more than 80%. (We've programmed it not to charge over 80%.) Even still, we are at risk that the car will burst into flames, potentially while we are in it, possibly with our grandchildren in the back seat. The other solution Mercedes has is that we should lease a different model at three times the cost of our present lease, thereby shifting the cost of this warranty issue onto us.

FUEL/PROPULSION SYSTEM
My 2023 Mercedes-Benz EQB 300 (VIN [XXX] ) is subject to a high-voltage battery safety recall involving a risk of internal short circuit and fire. Mercedes-Benz has acknowledged that the battery pack in affected vehicles can fail at high state of charge and may cause a thermal event while driving or parked. There is currently NO REMEDY available. Mercedes has already issued prior recalls attempting software fixes, but those did not resolve the defect. The manufacturer now states that the only remedy is full battery replacement, yet replacement battery packs are not available and no timeline has been provided. I have been instructed to park the vehicle outdoors due to fire risk. This is a major safety hazard that affects my home, property, and personal safety. The vehicle’s value is significantly diminished, and I am unable to use it normally because the manufacturer cannot repair it. Mercedes-Benz has failed to provide a remedy within a reasonable time for a serious safety defect. I am requesting NHTSA intervention to compel Mercedes-Benz to provide a repair, replacement vehicle, or buyback, as required under federal recall law when a remedy is unavailable. This situation is unacceptable for a safety-critical recall involving fire risk, and I am asking NHTSA to take action to ensure Mercedes-Benz complies with its obligations.

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)

UNKNOWN OR OTHER
I am reporting a serious safety hazard involving my Mercedes‑Benz EQB 350. Drive only 1.5 year, Jan 6, 2026, the vehicle suffered an electronic failure at LaGuardia Airport and became completely inoperable. It could not shift into Drive, Reverse, or Neutral and had to be towed to Mercedes‑Benz of Huntington for warranty repair. During service, the dealer performed a wheel alignment on Jan 16, 2026 without my authorization. I had previously declined alignment recommendations because my factory alignment was excellent and my tires were wearing evenly. Within four weeks of this unauthorized alignment (under 1,000 miles), all four tires developed severe inner‑edge destruction. Both rear tires wore down to exposed steel cords, causing air leakage and creating an imminent blowout risk. The front tires also show abnormal inner‑edge wear. The remaining tread on all tires is otherwise good, which is consistent with incorrect alignment rather than normal wear. An automotive engineer confirmed this rapid structural failure is physically impossible through normal driving and is a direct result of incorrect or defective alignment parameters set during the Jan 16 service. This unauthorized and incorrect repair turned my vehicle into a safety hazard for my family. I contacted Mercedes‑Benz USA (MBUSA) immediately and provided photos, documentation, and Case # CMS 20671727. For more than 14 days, MBUSA no response. Representatives gave inconsistent and implausible explanations, including blaming the towing process, which cannot cause this pattern of wear. MBUSA repeatedly redirected me back to the same dealer that performed the unauthorized repair, a clear conflict of interest. Their handling of this case shows dishonesty and an attempt to avoid responsibility, despite clear evidence of a safety‑related defect. I request that NHTSA review this matter as a potential safety defect involving electronic failure, unauthorized repair, incorrect alignment, and rapid tire degradation.

I am reporting a substantial safety defect regarding the high-voltage battery system in my 2023 Mercedes-Benz EQB 350. The vehicle suffers from a 50% loss of advertised range (real-world range of ~95 miles vs. 210 miles advertised) and severe DC fast-charging failures. My VIN is subject to NHTSA Recalls 25V050000 and 25V894 for high-voltage battery fire risk. Per the manufacturer's safety instructions, I have been told not to charge the vehicle above 80%, which further degrades the vehicle’s utility. Additionally, the vehicle is subject to Recall 25V487000 for sudden loss of drive power. Mercedes-Benz has failed to provide a permanent remedy that restores the vehicle's safe operating performance. The combination of fire risk, restricted charging capacity, and unpredictable power loss makes this vehicle unsafe for road use. The manufacturer has formally refused a repurchase despite these documented federal safety violations.

This safety recall is over six months old and is still unresolved. I have not felt safe driving the vehicle on the highway because of the possibility of complete power loss. I have been forced to keep paying lease payments on a car I can't drive and the manufacturer has been unresponsive. When I plug the car in to charge, all the lights in the house dim. My other EV does not do this so it must be a serious problem with this vehicle.

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?

I own a 2023 Mercedes-Benz EQB 300. After the dealership performed the recall Update Battery Management System Software – Campaign 2025040005 / 25V050 / 25P5496507, my vehicle immediately experienced a significant loss of battery performance. Problems that began right after the recall update: Driving range decreased by approximately 25–30 miles. DC fast-charging speed dropped from about 100 kW before the update to a maximum of around 80 kW after the update. Vehicle was performing normally before the recall software was installed. This update appears to have negatively affected the performance, efficiency, and charging capability of the high-voltage battery. Mercedes has not yet provided an explanation or solution. I am requesting that NHTSA investigate whether the recall update is improperly derating or limiting the high-voltage battery and whether this safety recall is causing reduced functionality for other EQB owners.

In December 2024, I brought my 2023 Mercedes-Benz EQB to Mercedes-Benz Beverly Hills for scheduled service. They told me the vehicle had a recall and booked me for a future appointment, but I was unable to attend because I was out of town. I called the dealer multiple times afterwards to reschedule, but they never told me the reason for the recall or explained the safety risk. I recently checked my VIN myself and discovered that the recall is related to a high-voltage battery defect that may cause sudden loss of power and battery fire. I was never properly informed by Mercedes-Benz about this serious safety hazard. I rely on this vehicle to transport my two young children. This is an electric vehicle with a battery fire risk and possible loss of power at highway speeds. Mercedes-Benz has not provided a remedy, repair, loaner vehicle, or timeline. I am requesting NHTSA assistance to ensure Mercedes-Benz addresses this safety recall or provides a safe replacement or loaner vehicle until repairs are available.

VISIBILITY/WIPER
The rear windshield shattered spontaneously without any external impact while the vehicle was parked. Mercedes-Benz USA advised bringing the vehicle to the dealership for evaluation of a possible manufacturing defect, but the dealer replaced the glass and charged for repair. This raises a concern for potential safety defect or glass stress failure in EQB models.
