2023 MERCEDES-BENZ EQS450+

I was stopped at a stop sign and when the light turn green I pressed the accelerator to move forward unfortunately, the vehicle hard braked for no reason. At first, I thought someone hit me from behind since there was no one in front of me but that was not the case. The braking was so violent that it caused my neck to snap back and forth, which caused the back of my head to hit the seat head support. I was going no faster then 10 mph but not slower then 5mph. In turn, the vehicle is available for inspection. My safety was at risk because I had no control or indicator that the braking was going to automatically brake on its own. The problem has not been reproduced or confirmed by the dealer or independent service center because the incident happened today (Sunday) therefore, I plan on making an appointment as soon as possible to see if they can identify any defects. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others since I plan on taking it to the Mercedes dealer where I purchased the vehicle. There were NO warning lamps, messages or other symptoms of the problem prior to failure.

While driving the Brakes locked in the middle of the Freeway and Street it happen 3 Times already and the only thing that the Service department from Mercedes Benz saids is that they cant duplicate the malfunction a return the car It Dangerous because it just stops the brakes lock and the car stops completly in the middle of the road

Around 5:48 pm Pacific time today, May 8, 2023, traveling westbound on Sunset Blvd (near the Drummond street intersection), the brakes suddenly engaged hard for a few seconds and then released and continued. Speed was around 35 mph and there were no obstructions around. This is the second incident of phantom braking that has occurred in 2 months. Luckily there was no car behind that could have collided into us from the sudden phantom braking.

I experienced a phantom braking incident yesterday in my 2023 EQS450+ SUV at 3:11 pm PST. Traveling at around 30 mph, no cars within 20 feet ahead or behind us, the car suddenly engaged the automatic brakes very hard with a loud beep but this condition lasted only a couple of seconds. The impact was hard enough to jolt all passengers in the car. The sound was as if something hit us from behind. Cruise control was not being used at that time. The car then continued to operate normally after that. I have set up a service appointment for this Friday, April 14 at the WI Simonson dealership in Los Angeles, CA. I have reported this to MErcedes Benz using their "contact me" feature on their website. From my research, it sounds like phantom braking is prevalent somewhat widely in the EQS cars but nothing seems to have been done about it so far.
