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.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM
At the time of the incident, I was pulling into a parking space in a parking lot near a park. I was traveling at approximately 3-5 miles per hour, consistent with idle or walking speed during a routine parking maneuver. I was nearly stopped and aligned with the parking space when the vehicle suddenly and unexpectedly accelerated without driver input. This occurred from a near-idle speed in a parking lot, not during roadway driving. During the unintended acceleration, the vehicle traveled over multiple curbs on both sides. No audible warnings, no beeping, no proximity alerts, no forward-collision warnings, and no automatic emergency braking activated at any time, despite the vehicle crossing curbs and approaching fixed objects. No warning lights illuminated. The vehicle continued accelerating without driver input and struck and knocked down a fixed light pole. After the impact, the vehicle continued moving forward until I immediately slammed on the brake and brought it to a stop in the middle of the adjacent roadway. No orange cones or warning devices were present prior to the incident. Any cones visible in photos were placed after the collision by responders for safety and traffic control. The sudden acceleration and complete lack of safety-system response occurred during a low-speed parking maneuver where the vehicle should not have accelerated beyond idle speed.

Although I have not experienced safety issues myself, this exact model+year combination has been recalled more than once: 2024 Mercedes EQB 300 4matic, and when I searched by my VIN it shows recall. I’m very concerned if my car is mistakenly not included - what if it has battery issue/fire risk but I am not aware? This poses huge safety risk on day to day driving. I request an investigation on this particular VIN and reasons of why it is not in the recall list despite all infos match.

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?

ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY:MANAGEMENT SYSTEM/ENERGY CONTROL MODULE (BMS/BECM):SOFTWARE
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.

SERVICE BRAKES, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
On [XXX] at [XXX], while I was slowly moving my car into a parking spot, the vehicle suddenly stopped for a brief moment and then, within a second, unexpectedly accelerated forward without any input from me. The car jumped onto the pathway and collided with the glass door of the property located at [XXX] ". I attempted to control the car using the brakes immediately, but the vehicle was not responding and remained out of control. There were no alert sounds or warnings before or during the incident. The vehicle finally stopped only after hitting the glass door. I strongly believe this was caused by a software or system bug, as the sudden acceleration occurred without my intervention. Please investigate this issue thoroughly, as it raises serious safety concerns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

My vehicle will not hold a charge. Since buying this car. I have been doing a lot of charging instead of driving. With normal charging, it takes approximately the whole day (24 hours) to have the vehicle charge over 80% and after that, the charge will not hold for a long time. This happens every time.

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.

The contact owns a 2022 Mercedes-Benz EQB 300 4MATIC. The contact stated that while driving approximately 45 MPH, there was an abnormal grinding sound coming from the rear of the vehicle, and the vehicle lost motive power. The contact stated that several unknown warnings illuminated. The MIL was illuminated, and the battery symbol was displayed. The messages “Reduced Drive System Performance" and "Towing not Permitted" were displayed. The accelerator pedal was depressed; however, the vehicle failed to respond as needed and stalled. The contact attempted to restart the vehicle, but the vehicle failed to restart. The vehicle was towed to a local dealer, where it was diagnosed, and several error codes for engine performance were retrieved. The vehicle was not repaired. The contact stated that the dealer had retrieved the same error codes one week prior when the vehicle was taken to be repaired under NHTSA Campaign Number: 25V050000 (Electrical System). The manufacturer was informed of the failure. The failure mileage was approximately 115,000.

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.

Prior to the recall this vehicle has had two incidents where it had to be brought into the dealership. One of those incidents caused the SUV to be in the shop for approx. a month where the battery was not holding a charge/could not be charged and the manufacture in Germany had to be contacted. The second time I driving out of town and the battery was fully charged (280 miles) for a 180 mile trip and by the time I arrived at my destination I had 30 miles remaining for a charge. I ran out of battery and had to be towed to another charging station because it failed to hold a charge at the station it was taken too. I informed the dealership then I did not feel safe in the vehicle and wanted to initiate a buy back. Mercedes informed me that the battery life could fluctuate depending on extreme hot or cold. The first time it was in the shop was October and the second was February approx. I reached out to the dealership when I became aware of the recall and said I wanted to be released from the lease and they stated they would look into a buy back and when the legal team contacted me the letter that was sent on May 4th stated that there was not enough repairs attempted on the vehicle to qualify. The letter did not address the open recall. When speaking to Mercedes Benz recall department they did admit that there is no remedy anticipated for the open recall. I have attempted to reach out and not received an answer to discuss options from Mercedes. They have ceased communicating with me about options I have connected to the recall.

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.

Dear Sir or Madam, Good day. I purchased a New 2023 Mercedes EQB [XXX] from a Dealership in Florida less than 2 years ago. This VIN is associated with NHTSA Recall 2025020001 25V050 Electrical System Battery Fire Risk dated February 3rd 2025. This recall is due to multiple cars spontaneously catching on fire. No cause has been identified or ruled out. Vehicle was previously serviced multiple times for Charging related issues. I spoke to the Dealership about this recall informally. They recommended against charging the car indoors. They said the part for the Recall was not yet available. While the Manufacturer recommends limiting charging in anticipation of a Remedy, no Remedy is available. They plan on providing a software patch, this could very well could be a hardware issue requiring hardware replacement. Having a recall with No Remedy for months puts this car out-of-service. Having a recall with No Remedy for months is a nonconformity. Only being able to charge to 80% is a nonconformity. Car has been out of service for months. The risk is simply too great to charge the car, store the car inside my home, or drive the car. I reached out to the Manufacturer under the Florida Lemon Law (attached) as this has exceeded a reasonable amount of time for a critical life safety repair. Thank you.
