ENGINE, POWER TRAIN, ELECTRICAL SYSTEM
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.

My vehicle is not included in the current high voltage battery recall under NHTSA recall 26V073, as it has a manufacture date of 08/2024 per door jamb sticker, however, page 5 of the NHTSA report explicitly states “A change in the production procedure of our supplier ensures that this issue can no longer occur on vehicles produced from July 31, 2024 onwards.” This leaves car production between May and July 31 (and likely beyond!) unaccounted for in the recall. My car was built in August 2024, likely with a battery manufactured prior to July 31, 2024 with the defect. I believe my car should be included in the recall/affected vehicles given its production date and the date of production remedy. I accessed the recall report here: [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

Mercedes previously issued a software update for the battery fire risk, but we have received a letter more than a year later stating that this fix was not adequate. We pursued a vehicle buyback due to the safety risk this presents to my family, and Mercedes vehemently stated that the issue was resolved and the vehicle did not qualify. The vehicle is an inherent risk to my family's safety if it may just catch fire at any time.

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.

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.

My vehicle is a 2024 Mercedes-Benz EQB 300. Despite the nationwide recall (NHTSA 26V073000) for high-voltage battery fire risk, the manufacturer is providing conflicting and dangerous safety information. I was verbally instructed by dealership representatives to park my vehicle outdoors and limit charging to 80% to avoid a fire hazard. However, when I requested written confirmation of these safety restrictions from MBUSA Corporate Retention (Case Manager: [XXX] ), my request was ignored The manufacturer refuses to put in writing that my vehicle is safe to park in my attached garage or charge to 100%, effectively leaving me with a fire hazard in my home while refusing to acknowledge the defect for my specific VIN. This is a critical failure of the recall management process. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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)
