ELECTRICAL SYSTEM
I am currently leasing a 2024 Mercedes-Benz EQB 250+. The vehicle displayed a warning related to the high-voltage battery system, indicating a potential malfunction and safety risk. I was advised that there may be an issue involving the high-voltage battery that could lead to battery failure and/or an increased risk of fire. Due to this warning, I no longer feel the vehicle is safe to operate or park near my home or other structures. The warning first appeared on the vehicle's dashboard while the vehicle was in normal use. The condition creates a significant safety concern because a high-voltage battery failure could potentially result in loss of propulsion, vehicle disablement, or a battery thermal event. The vehicle has been inspected and/or is scheduled for inspection by an authorized Mercedes-Benz dealership. The issue was brought to the attention of Mercedes-Benz of Rocklin. During my communications with the dealership, I was advised to pursue a vehicle buyback due to the severity of the situation and concerns surrounding the high-voltage battery. However, after I began pursuing that option, I was later informed that a buyback would not proceed. This conflicting guidance has left me with a vehicle that I have concerns about operating safely. Although I was initially led to believe the issue was significant enough to warrant a buyback, I am still in possession of the vehicle and continue to have concerns regarding the safety and reliability of the high-voltage battery system. The vehicle can be made available for inspection upon request. I am submitting this complaint because I believe a potential defect involving the high-voltage battery system presents a risk to drivers, passengers, and the public. I request that NHTSA review and investigate this issue to determine whether additional action is necessary to protect consumers.

ELECTRICAL SYSTEM
I was driving very slowly down a residential side street and started to pull over to the right side to park behind a car. This parking spot was on a slight incline and the curb was made up of two slanted cobblestones. After I moved in to position within about 2 ft from the car in front of me, my car quickly accelerated and slammed in to it. While I did not notice it at the time, after noticing the nature of the damage to both cars, it appeared as though the car may have tried to swerve from the curb. I believe the front sensors detected there was something in the way and the car swerved left hitting the parked car in front of me. There were no warnings before the event and I did not notice the warnings on the dashboard when the car collided because I was too upset and got out quickly, but I definitely noticed that the dashboard was lit up. Progressive Insurance, Mercedes Customer Service and Hanover MA Dealership, and Norwell Collision have all since been involved. The car was towed to the body shop immediately after the incident. Mercedes Service at first advised me to keep the car as is until they had a chance to run tests, but then advised us to get the car repaired at the body shop so we didn't wait to long to get it back (I had told them that I would not drive it again unless Mercedes ran full diagnostics and convinced me that it was safe to drive). The body shop made the repairs and then delivered the car to Mercedes Hanover to run tests. They believe the car is fine and are delivering it back to the body shop where we are supposed to pick it up. Progressive has mailed claim checks which we are using to pay the body shop, however this is not an admittance of any wrong doing. I strongly believe that the car was at fault.

ELECTRICAL SYSTEM
I own a 2024 Mercedes-Benz EQB 300 4MATIC, VIN [XXX], manufactured in XXX. I am requesting a formal safety review regarding NHTSA recall 26V073, involving potential high-voltage battery fires. The official NHTSA recall report lists XXX, as the last affected vehicle production date. However, page 5 states that the supplier production correction became effective for vehicles produced from XXX onward. My vehicle was manufactured between these dates but does not appear to qualify for the replacement recall. I do have multiple battery charging failures. I have reached out to benz as well. Please open a formal customer assistance case, provide a case number, and respond in writing with the findings of your technical review. Thank you.

ELECTRICAL SYSTEM, ENGINE
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.

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

FUEL/PROPULSION SYSTEM
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.

ENGINE
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)

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.

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)
