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 contact stated that a chemical odor was emitting from the engine weeks before the incident. The failure mileage was 20,000.

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)

The contact owns a 2023 Mercedes-Benz EQB300. The contact stated that while driving 60 MPH, the vehicle lost automotive power and decelerated to 30 MPH. The contact drove the vehicle to a local charging station to recharge the battery; however, the vehicle failed to recharge. No warning lights were illuminated. The vehicle was towed to a local dealer where the vehicle was diagnosed, and the contact was informed that the battery had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 5,000.

Since new in April 2023, I have had 6 flat tires in less than 12,000 miles. Always the same failure mode: tearing by rock chips. I have been advised by the Mercedes dealer that at my own expense, I can replace the tires. The tire dealer noted that the low profile wheel/tire combination as this vehicle has as standard equipment, is subject to rock tears. This is an SUV and there is no advice to avoid gravel roads such as my own driveway. This vehicle is unreliable. I have had the same driveway since 2006 with no history of flat tires.

Within one week of car purchase, the car is alerting that the SRS system is not working and it needs to be taken to a dealership. Dealership doesn't have am timeline on when they will be able to fix it.

We were driving along a 4 lane state road and the car suddenly applied the brakes hard and swerved to the right. A light blinked on the dash with a picture of the car and a red line on the right hand side. No cars were in the next lane over and there were no issues with the roadway. I was driving straight in the line and not near the left hand side of the Lane.

There is a reflective chrome accent on the dashboard of the EQB 300 that reflects sunlight directly into the drivers eyes when the car is oriented in certain directions at certain times of day. The light is blinding and impacts the ability of the driver to see the road and respond appropriately. I notified the dealership and Mercedes customer service, and they said there was nothing that they could do and that this was a buyer beware type situation.
