2024 Mercedes-Benz C-Class Brakes Problems

I had to take a detour one night coming home, the detour led to a bridge that connects to a highway. Approaching the bridge my car started to jerk and pop up with all of these notification about “blind spot assistance” is down, “car engine failure, please check user manual”, “car malfunction” with a engine battery symbol. All the while the engine light was on. All these warning was popping up one after another, while I was trying to merge onto the bridge. Mind you there is no shoulder currently during the active merging or on the bridge, but I didn’t think of what would happen next. As I merge onto the bridge at 35mph the car shuts off completely on me. My car automatically sets itself into Neutral mode and I was rolling on the bridge at 35mph, no shoulder and no brakes or gas to move properly. I called the police but they won’t dispatch a officer unless I am in a accident or about to cause on, but they heard I am rolling at 35mph and they said from her words herself “I can’t send a officer over for your reason ma’am, are you a threat to others or about to crash? Can’t you just brake?” My car system never turned back on, I stepped my foot on the brakes all the way praying something will work as I existed the bridge onto a small shoulder. The emergency brakes came on as I keep swerving onto the grass. As everyone was going 65mph I don’t know why I wouldn’t impose as a threat if I have no control over my car from oncoming traffic. This is a very dangerous situation, and my service shop said we try to retest the issue/diagnostics but couldn’t replicate the situation and told me that my car is fine. But this isn’t the first time that happened and it also wasn’t the last. I don’t know what test they’re running but telling me it’s a simple system malfunction error every time is playing with my lifespan. Do not recommend.

The vehicle appears to have experienced a braking system malfunction, possibly involving the brake-by-wire system, electronic stability control (ESC), or unintended acceleration event. When the brake pedal was fully depressed, the car suddenly and uncontrollably accelerated forward into a cinder block wall. After the incident, it was observed that only the left-side tires left skid marks, indicating an apparent brake imbalance or failure on the right side. The vehicle is available for inspection upon request. My safety and the safety of others were severely compromised. My daughter and I were in the car during this and are extremely traumatized. Despite pressing the brake pedal, the vehicle accelerated forward and crashed into a cinder block wall, which could have resulted in serious injury or death had a person, pedestrian, or oncoming vehicle been in front. This type of malfunction poses a critical risk of high-speed unintended collisions in public or residential areas. As of now, the problem has not yet been reproduced or confirmed by a dealer or service center, but further inspection is pending. I am requesting a full diagnostic evaluation, including electronic and mechanical systems related to throttle and braking. The vehicle has not yet been inspected by Mercedes-Benz, police, or insurance representatives, but the car is in the possession of a Mercedes’ collision center. NO, there were no warning lamps, messages, or unusual symptoms on the dashboard prior to the event. The vehicle gave no indication of mechanical or electronic failure before the sudden acceleration occurred.
