I own a 2023 Mercedes-Benz EQB 300 4MATIC. My vehicle has multiple unresolved high-voltage battery safety recalls. Recall 25V050/MBUSA campaign 2025040005 concerns a potential internal battery-cell short circuit and fire risk. I had the BMS software update performed, but Mercedes later issued recall 26V073 because the software remedy was not considered sufficient for all affected vehicles. Recall 26V073 requires complete high-voltage battery replacement. Until that repair is completed, Mercedes instructs owners to park outside and away from structures and limit charging to 80%. My vehicle also shows recall 25V487/MBUSA campaign 2025070009 as pending. This recall concerns a battery busbar connection that could cause sudden loss of propulsion without warning, increasing the risk of a crash. Despite the ongoing fire-risk and loss-of-propulsion concerns, I have not been provided a firm, VIN-specific date for the battery replacement. The safety restrictions significantly limit my ability to use and safely park the vehicle. I am concerned that the permanent remedy remains unavailable while I continue to make lease payments.

I am the owner of a 2023 Mercedes-Benz EQB that has been identified as being affected by the current high-voltage battery safety recall. I recently contacted my authorized Mercedes-Benz dealer regarding the recall and was informed that the recall is currently pending for my vehicle and that the permanent remedy is not expected to begin until approximately December. I understand that the interim safety guidance associated with this recall includes limiting charging to 80% and parking the vehicle outside and away from structures. I have a significant concern regarding the parking instruction. My vehicle is normally parked in an attached garage at my condominium. The garage is connected to my residence, and my HOA does not permit me to park the vehicle outside. Therefore, I do not have a practical way to comply with the instruction to park outside and away from structures. I specifically raised this issue with the service department. I was told verbally that I could continue parking the vehicle in my garage “at my discretion.”

The affected component is the high-voltage traction battery and related battery management and bus-bar connection systems. My vehicle is available for inspection upon request. I am reporting a safety concern because my vehicle is subject to NHTSA Recall 25V050, which identifies a risk that the high-voltage battery could fail internally and cause a fire while parked or driving. It is also subject to NHTSA Recall 25V487, which identifies a defect involving the high-voltage battery bus-bar connection that may cause a sudden loss of drive power without warning. A battery fire could endanger vehicle occupants and people or property near a parked vehicle. A sudden loss of propulsion while driving could increase the risk of a crash. I have not personally experienced a vehicle fire or a sudden loss of drive power. However, I am being asked to continue operating and making lease payments on a vehicle with identified high-voltage battery safety defects and no completed effective remedy available for my vehicle. The currently available guidance limits charging to 80%, which reduces the vehicle’s usable range and practical value. The vehicle’s recall status has been confirmed through NHTSA and Mercedes-Benz recall information. To my knowledge, no dealer repair has been completed that eliminates these safety concerns. The vehicle has not been inspected by police, insurance representatives, or an independent service center in connection with an incident because no crash, fire, or loss-of-p

Vehicle: 2023 Mercedes‑Benz EQB VIN: [XXX] MBUSA Case #: XXX NHTSA Recall #: 26V073000 Mercedes‑Benz USA has mishandled recall 26V073000 (fire hazard) and left me without transportation. I was told the vehicle is unsafe to drive, which has caused significant anxiety, panic attacks, and ongoing stress because I have no safe way to commute or manage daily responsibilities. MBUSA repeatedly promised a loaner vehicle, but the dealership stated they were never contacted, had no instructions, and had no loaner available. MBUSA later said I could receive a rental car “upon eligible dealership,” but they did not specify which dealership, and after calling multiple Mercedes‑Benz locations, all confirmed they had no information, no authorization, and no process for rental reimbursement or recall support. MBUSA has provided conflicting and misleading information, failed to coordinate with dealerships, and failed to provide transportation during a fire‑hazard recall. This has caused loss of use, mental distress, and safety exposure. I request investigation into MBUSA for failure to properly administer recall 26V073000, failure to provide transportation during a safety recall, and misrepresentation of recall remedies.

There is a recall associated with this model that causes catastrophic stoppage without any ability to drive. My vehicle VIN does not have a recall according to your site. Despite this, my vehicle catastrophically stopped multiple times. It was repaired at least three times and still stopped in the middle of the highway. My partner and I were stopped on I-85S with no ability to move, honk, put on hazards. Cars zoomed past at full speed. I called 911 as we braced for impact. We are lucky to be alive and now suffer from severe trauma. They eventually closed the entire highway and dragged the vehicle to the shoulder almost 30 min later. Mbusa was aware of this defect before rejecting my lemon law claim, but my vehicle was not included apparently. I feel more investigation is needed because it seems very likely my vehicle should be included in the recall. I appreciate your attention to this matter.

My 2023 Mercedes-Benz EQB is included in the high-voltage battery fire recall (NHTSA campaign 26V073). The recall states the battery cells may fail internally at a high state of charge, causing an internal short circuit and a potential fire whether the vehicle is parked or being driven, with no advance warning while parked. As interim safety measures, Mercedes-Benz instructed me to limit charging to 80% and to park the vehicle outdoors, away from structures. These restrictions materially impair the vehicle's use: I cannot charge to full capacity and cannot park in my garage due to the fire risk to my home. The permanent remedy is replacement of the high-voltage battery pack. However, my Mercedes-Benz dealer has informed me that the replacement parts will not be available until 2027. That means I am being asked to operate a vehicle with an acknowledged fire risk, under charging and parking restrictions, for roughly 18 months or more, with no remedy currently available. I am requesting that NHTSA document this lack of an available remedy and the extended timeline. A delay of this length leaves owners exposed to the safety defect the recall was issued to address.

I am reporting a significant safety concern regarding my 2023 Mercedes-Benz EQB. While my specific VIN has not been included in the current high-voltage battery fire risk recall (NHTSA Campaign 26V073000), my vehicle is a 2023 model that shares the identical high-voltage battery architecture, manufacturing window, and platform design as the approximately 12,000 EQB vehicles officially recalled due to an internal defect that causes sudden, unpredictable battery fires. As a vehicle owner, I am now experiencing deep, well-founded anxiety regarding the safety of this vehicle. Due to the proximity of my vehicle's design to those definitively identified as defective, I have lost confidence in the vehicle's safe operation. I can no longer park this vehicle in an enclosed garage or charge it with confidence, effectively limiting my ability to utilize the vehicle as intended. I am filing this report to formally document my concern that this safety defect may be more widespread than the current recall population suggests, posing an unreasonable risk to the safety of myself and the public.

MB recall is since Feb 2026 and they neither ready to fix it not ready to provide a proper compensation . The vehicle is currently unusable for the following reasons: 1. Safety Catch-22 (Fire vs. Theft): Due to the fire hazard associated with the current battery recall, I cannot safely charge or store the vehicle in my garage. However, the local Township Police have explicitly advised against keeping the car outside due to high theft risks in the area. Mercedes-Benz has essentially provided a vehicle that is neither safe to keep indoors nor secure to keep outdoors. 2. Home Charging Restrictions: I typically charge the vehicle at night; however, the current recall guidelines necessitate monitoring the charge to ensure it does not exceed 80%. I have no practical way to monitor this throughout the night, making home charging a safety liability. Public Infrastructure Failure: The EVgo charging network has blocked the Mercedes-Benz EQB model from their network due to these safety concerns. This further eliminates my ability to use the vehicle for standard commuting or travel. 3. Lack of Support and Loaner Access: Despite these documented safety risks, my local Mercedes-Benz dealer has refused to provide a loaner vehicle, stating they are awaiting specific instructions from corporate. This leaves me without a safe mode of transportation while I continue to pay for a vehicle I cannot use. 4.

I received an Important Safety Recall notice (NHTSA Recall ID: 26V073) from Mercedes-Benz USA in March 2026 regarding my 2024 EQB (VIN: [XXX] ). The notice states that the high-voltage battery may fail due to an internal short circuit, potentially causing a vehicle fire while parked or driving. No incident has occurred. This complaint is filed because no remedy is available and no timeline has been provided by the manufacturer. Mercedes-Benz has advised owners to limit charging to 80% and to park outside while awaiting battery replacement parts. This interim guidance creates an additional hardship: my vehicle is garaged in ZIP code 98119 (Seattle, WA), where property crime is documented at over 50% above the national average. The manufacturer's guidance forces me to expose a $55,000+ vehicle to elevated theft and vandalism risk indefinitely, through no fault of my own. I am requesting NHTSA pressure Mercedes-Benz to accelerate parts availability and provide affected owners with a loaner vehicle or covered parking reimbursement until the remedy is performed.

I am requesting that my 2023 Mercedes‑Benz EQB be added to the recall associated with high‑voltage battery safety issues. My vehicle is exhibiting the same symptoms described in NHTSA Recall No. 26V073000, but my VIN is not currently included. I was instructed not to fully charge the vehicle and warned that it may pose a fire hazard if parked inside my garage. These warnings indicate a serious safety defect involving the high‑voltage battery system. The vehicle cannot be safely stored at my residence, and its normal operation is substantially impaired. The safety risk is significant: the vehicle may overheat or catch fire during charging or while parked. This creates a danger to occupants, nearby structures, and the public. The problem has been acknowledged by the manufacturer in communications but no permanent repair is available. The symptoms and restrictions match those described in the existing recall. I am requesting that NHTSA investigate and determine whether my vehicle should be added to the affected VIN list, as it appears to suffer from the same high‑voltage battery defect and presents the same safety hazards.

Compounded Electrical Failures In addition to the battery defect, this specific vehicle has exhibited recurring electrical malfunctions, including: Total failure of the backup cameras and parking sensors. Intermittent failure of the HVAC system (Air Conditioning), critical in the Florida climate. Erratic Autonomous Braking: The vehicle has repeatedly engaged emergency braking while reversing without cause, nearly resulting in multiple collisions. Diminished Utility and Breach of Lease Expectations The "interim" instructions provided by Mercedes-Benz have fundamentally altered the vehicle’s functionality from the terms established at the start of my lease: Charge Limitation: The "MUST NOT exceed 80%" mandate reduces the vehicle's range and utility, failing to meet the deliverable of a fully functional EV. Parking Restrictions: The requirement to park outside for fear of a garage fire is an unreasonable burden that violates the expected use of a luxury vehicle. Failure to Remedy within a Reasonable Time (49 U.S.C. § 30120) Under the National Traffic and Motor Vehicle Safety Act, specifically 49 U.S.C. § 30120(c)(2), a manufacturer’s failure to remedy a defect within 60 days of a vehicle being presented or a notice being issued constitutes prima facie evidence of a failure to remedy within a reasonable time.

I received an official recall notice from Mercedes-Benz regarding my EQB due to a defect involving the high-voltage battery system. According to the recall notice, the battery may experience an internal failure that could potentially result in a fire while the vehicle is either parked or being driven. Mercedes-Benz has also advised owners to limit charging and park the vehicle outside due to the severity of the safety risk. At this time, Mercedes-Benz has not provided a permanent repair remedy or battery replacement. Because I no longer feel safe driving or storing the vehicle, I have left it at the dealership and am currently using a loaner vehicle while attempting to reach a fair and reasonable resolution with Mercedes-Benz. Given the serious safety concerns associated with this recall and the lack of an available repair, I do not believe the current offer being presented by Mercedes-Benz adequately resolves the situation. During my first conversation with Mercedes, I was clearly told that I had two options: trade into another lease or have Mercedes repurchase the vehicle at no cost to me. At no point during that initial conversation was I told that repurchase was unlikely or subject to higher-level approval. $7,500 does not address the core issue, which is that I am still left in a lease for a vehicle I do not feel safe driving or storing. This is fundamentally a safety and usability issue, not simply a financial inconvenience. I am simply asking Mercedes to stand behind i

Dear NHTSA Safety Team, I am submitting a formal safety-related complaint regarding my 2023 Mercedes-Benz EQB 250, which is currently under an active high-voltage battery recall. The recall imposes significant safety restrictions, including an 80% charging limit, a requirement to park the vehicle outside due to fire risk, and the inability to safely charge the vehicle at home. Additionally, I have been advised by my dealership that DC fast charging should not be used, further limiting the vehicle’s usability. Mercedes-Benz has informed me that the remedy requires a full high-voltage battery replacement, which may take many months (until at least December). In the meantime, the vehicle is not usable as a daily vehicle due to the combined safety and charging restrictions. I have attempted to work with Mercedes-Benz USA to obtain an appropriate remedy for this loss of use, but I have been told that only minimal options are available, and my request for executive-level review has been denied. I am requesting NHTSA’s assistance in reviewing this matter as a safety-related loss-of-use issue. The current restrictions materially affect my ability to safely operate and maintain the vehicle. Thank you for your attention to this matter. Sincerely, [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.

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.

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 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.

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.

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.

On October 8, 2025 the sunroof exploded from within while driving. There was no external force involved. It sounded like a gunshot going off in the car. My wife and I looked at each other expecting to see blood, but fortunately, there was none. We were both quite shook up. Upon inspection the remaining shards of glass were pointed upward, although that is difficult to see from the pictures. Fortunately, the shade was closed so the glass shards did not fall on me or my wife. No other debris besides broken glass was found on the shade.

Mercedes performed a recall and stated the charging would increase only by 10-15 minutes. For my vehicle it is now exceeding 30-45 minutes to get to the same state of charge at a fast charger such as electrify America. Mercedes refuses to do anything about this, instead they want me to drive around with a defective battery which still has a potential to catch on fire.

When driving above 40 mph, I have experienced seemingly random brakes, which most likely is due to the automatic emergency braking system. I have seen it work properly when a car cuts me off in traffic, which it makes sense then. But in several instances, it's pumped the brakes when there is no obstacle or car around. It's quite scary since you might get hit from behind. One time it braked so suddenly I was jolted forward in my seat. It also has an issue with parking sensors going off also randomly going under 10 mph. All of them activate on red.

The contact owns a 2023 Mercedes-Benz EQB 300. The contact stated that his wife was parking inside the garage, and the brake pedal was depressed she felt the brake pedal was vibrating, and the vehicle then accelerated independently. The contact stated that after several times depressing the brake pedal, the vehicle was able to come to a stop. It was unknown if the warning lights illuminated. On a separate occasion, the contact was driving at 5 MPH coming to a stop, the brake pedal was released and felt abnormal vibration; the vehicle then accelerated independently. The vehicle jumped the curb and crashed into a tree trunk where it came to a stop. The driver’s and passenger’s side air bags did not deploy. The contact was unsure if there was a warning light illuminated on that occasion. A police report was not filed. There were no injuries sustained. The vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The insurance company was not contacted. The manufacturer was notified of the failure and advised the contact that a case manager would be reaching out.

The EQB is advertised by Mercedes of having a range of 232 to 260 miles. The actual range currently is 145 miles, far less than what Mercedes advertises. I understand winter charging decrease range but not by 38 percent. That’s not acceptable. There are 4 EV’s at my dealer today all complaining about lack of advertised range. My car has been into service three times over the last month and will be going back in soon forms fourth time. The first two times, the dealer updated EV software, resolved a battery fault and the range only gets worse. I strongly suggest the NHTSA investigate Mercedes on their false advertising and issue a recall regarding poor range. If the NHTSA needs additional information, please email me at [XXX] or call [XXX] . Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Complaints 1-50 of 54, newest first, reproduced as filed.
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
