- #11752544July 23, 2026UNKNOWN OR OTHER
After I parked my car, I was walking in between another parked car and my vehicle and the tailpipe burnt the back of my left calf. I got out of the driver side. I was driving the car. This is also happened about six months ago to my daughter, who was exiting the car from the backseat and burnt her leg on the tailpipe because the tailpipe of this vehicle is located right under the passenger’s door and sticks out. I uploaded photos of the second-degree burn that I have. It’s blistering now.

I received a recall notice for this vehicle stating that the wheels may not be safely attached and could come off back in early May. It's been over a month and Mercedes has no solution for the recall at this time. I'm looking to get help with not having to pay my lease since I cannot use the car safely.

While driving at around 35mph, the recently-installed rear left snow tire on the car popped off and was propelled several hundred feet down the road. Upon reviewing the recall information of the car, it seems likely the indicent was caused by defective wheel bolts.

- #11743263June 10, 2026SEAT BELTS, FORWARD COLLISION AVOIDANCE: WARNINGS, VEHICLE SPEED CONTROL
While driving on a California freeway at highway speed, the vehicle unexpectedly decelerated and the seatbelts tightened as though a collision avoidance or emergency safety system had activated. There was no apparent vehicle, obstacle, or roadway hazard present that would explain the event. The incident occurred while family members, including a child passenger, were in the vehicle. The unexpected deceleration and seatbelt tightening created a significant safety concern because it occurred at freeway speeds without warning. Shortly after the incident, the check engine light illuminated and the vehicle was taken to an authorized Mercedes-Benz dealership for inspection. The dealership documented our complaint that the vehicle slowed on its own and that the seatbelts tightened when no other vehicle was around. The dealership later stated that it was unable to duplicate the concern and reported no fault found. Prior to this event, the vehicle had experienced multiple electronic-related issues, including failure to recognize the key while it was inside the vehicle, repeated "missing key" warnings while driving, and other warning messages requiring dealership diagnosis and software updates. After the freeway incident, the Forward Collision Warning returned, increasing concerns that the vehicle's collision avoidance or driver assistance systems may not be operating correctly. Because of the unexpected freeway deceleration, seatbelt tightening, warning messages, and prior electronic issues, we no longer have confidence in the vehicle's safety and reliability. The cause of the incident remains unknown.

- #11695920October 27, 2025FORWARD COLLISION AVOIDANCE: WARNINGS, UNKNOWN OR OTHER
Mercedes G63 with approx. 3500 miles will suddenly enter into collision avoidance mode. Specifically, the seatbelts will tighten up and the brakes will fully engage to stop the vehicle. In all cases, there was no risk of collision and the system engages with false positive alerts. The console display will indicate the area where the vehicle believed a collision may occur and there is nothing in that vicinity. The risk of injury and bodily harm is significant with this system as the vehicle is uncontrollable and can be rear-ended among other situations. The dealership inspected and confirms fault codes and they updated the vehicle's software but the issue persists. Merecedes should immediately recall all vehicles.
