VEHICLE SPEED CONTROL, UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM
I was driving my 2025 Mercedes EQB home after work August 11, 2026 and reached the end of my cul de sac, slowly turning left into my carport. As the front tires reached the sidewalk the car suddenly accelerated at extremely shocking high speed heading straight towards another car parked in there and the front wall. I slammed on the brakes and was fortunately able to stop the car right before it hit the wall and the other car. It was terrifying. Luckily I did not hit my dog who was outside at the time. There are tire skid marks on the carport concrete. I turned the car off and gathered myself then turned it back on, everything seemed normal and I reparked it so I could get out. Everyone inside had heard a loud noise/screeching. I am now too scared to drive the car. It is at Mercedes being checked out but so far they have found no issues. I definitely am not at fault, there were no loose shoes or floor mats etc.

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.

The battery in this car can catch fire at any time while parked. The dealership would not take the car to inspect, repair or replace the battery because there is no remedy available at this time. The recall information go back to January 2026 with no remedy or resolution available period. Instructions say I can charge it only up to 80%. I have to make adjustments to my daily routine. Instructions say I have to park it away from buildings. This car is a serious safety hazard for humans and buildings.

PRIORITY COMPLAINT: MANUFACTURER RECALL OBSTRUCTION & COERCIVE SAFETY WAIVER INDUCEMENT. My vehicle is actively subject to NHTSA Campaign 26V073 for a severe high-voltage battery defect causing an immediate fire hazard while parked or operating. Because the manufacturer has no immediate remedy available, I filed an administrative buyback request due to the extreme danger of driving the car. Mercedes-Benz USA (MBUSA) has formally blocked my safety relief by deceptively citing irrelevant Florida Lemon Laws, despite the vehicle being legally purchased in Maryland and registered/operated continuously in Virginia. Furthermore, MBUSA is actively attempting to obstruct the safety intent of this NHTSA recall by trying to bribe me with a $5,500 cash payment in exchange for signing a mandatory "Waiver of Rights" liability release. This release legally bars me from pursuing future recall remedies or lawsuits if the battery catches fire. MBUSA has explicitly stated in writing that if I refuse to sign this total liability waiver, they will offer zero further assistance, effectively forcing me to continue operating a known, catastrophic fire hazard on public roads. I request that NHTSA’s Office of Defects Investigation (ODI) launch an immediate inquiry into MBUSA for utilizing deceptive out-of-state legal tactics and coercive monetary waivers to suppress safety claims and minimize their financial exposure to Campaign 26V073.

Learning that my vehicle is subject to a battery-related recall has seriously undermined my trust. Battery defects in electric vehicles can present risks that include thermal events, loss of vehicle functionality, and other potentially dangerous situations. My vehicle has had warning signs, I received emails about the risks my vehicle can present directly from Mercedes. I have had my vehicle in the service department two times in two months for this same issue. My vehicle is overheating while charging.

FUEL/PROPULSION SYSTEM
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.

ELECTRICAL SYSTEM, ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS
I am submitting this complaint regarding a serious safety issue involving my vehicle. For an extended period of time, this vehicle has experienced recurring starting failures. On multiple occasions, the vehicle would not start, requiring service visits to the dealership. Despite repeated repair attempts, the dealership was unable to identify the root cause of the problem and typically performed only software updates. I was repeatedly informed that no specific defect could be found.Recently, the issue escalated into a much more dangerous event. While driving, the engine suddenly shut down without warning. The loss of engine power occurred during normal vehicle operation and created a significant safety hazard. This unexpected engine shutdown could have resulted in a collision, serious injury, or loss of vehicle control, particularly if it had occurred in heavy traffic or at highway speeds.What is especially concerning is that this incident appears to be related to the same unresolved condition that has resulted in multiple prior service visits. The vehicle has a documented history of similar symptoms, yet the underlying cause has never been identified or permanently corrected.Based on the repeated failures, unsuccessful repair attempts, and the recent engine shutdown while driving, I am concerned that this vehicle may have a safety-related defect affecting its reliability and safe operation. I am submitting this complaint so that the issue can be investigated and evaluated for potential broader safety implications.The vehicle continues to cause concern whenever it is driven because there is no assurance that the engine will not shut down again unexpectedly.

Electrical System/Climate Control/Energy Management DESCRIPTION OF PROBLEM: On XXX, I exited my 2024 Mercedes-Benz EQB 250+ at a parking lot in [XXX] to briefly enter a business. I left the vehicle running in Park and I took the key fob with me and left the climate control (AC) active. Three occupants remained inside the car: my wife, son, and dog. Without any warning, alert, or notification to the remaining occupants, the car automatically shut down its drivetrain and climate control system after approximately 5 to 10 minutes of idle time. The interior temperature in TX in summer conditions can reach dangerous levels within minutes of AC loss, creating a life-threatening situation for car occupants. The car provides no prominent warning to the driver at the time of exit that this automatic shutoff will occur. There is no accessible, clearly labeled setting to disable this behavior. The only known workaround — pressing a small fan icon on the lower display screen before opening the door after powering off — is non-intuitive, undisclosed in routine car operation, and limited to approximately 30 minutes. This design is in stark contrast to competing electric cars (e.g., Tesla) which offer an explicit, clearly labeled "Keep Climate On" or "Dog Mode" feature that maintains cabin temperature indefinitely when occupants are present. In high-heat states such as Texas, where temperatures routinely exceed 100°F, an unexpected and unannounced climate system shutdown poses a serious and foreseeable risk of heat stroke, injury, or death, particularly to children, elderly individuals, and animals who cannot self-rescue. I am requesting that NHTSA investigate this as a potential safety defect and evaluate whether Mercedes EQ cars equipped with this automatic idle shutoff behavior require a design change, software update, or recall to add adequate safeguards. No crash or injury occurred in this incident. This complaint is being filed to prevent future harm. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

ELECTRICAL SYSTEM, ENGINE
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.

FUEL/PROPULSION SYSTEM
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. Financial Loss: I am currently paying monthly insurance premiums of approx $300, car payments of $529, and have recently invested in new tires for a vehicle (~$1200) that is sitting idle. I am incurring the full cost of ownership for a product that fails to meet basic safety and utility standards. I need NHTSA to help me here as MB is not able to honor its federal mandate
