Owner report 11516386 · 2023-04-10 (April 10, 2023)
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 Fr…

Owner report 11521077 · 2023-05-08 (May 8, 2023)
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.

Owner report 11528510 · 2023-06-23 (June 23, 2023)
On 05Jun23, EQS 450+ suddenly reduced the speed to 30mph on the SRT highway while I was driving with cruise control set to 70mph.

This happens multiple times when I was driving on the different highways in Texas as well as in FM roads. Car’s Behavior while Cruise control is SET to 70+mph and Intelligent Recuperation is ON. Highway Speed Sign is 70mph. 🔴 Sudden, unexpected deceleration …

Owner report 11542343 · 2023-09-03 (September 3, 2023)
As I was traveling on a highway at 70 mph in my 2023 Mercedes-Benz EQS, 450+, the overhead sunroof glass spontaneously exploded without warning or signs. The glass blew out edge to edge into hundreds of tiny pieces of tempered glass. If it had not been for my *closed* cloth sunroof sunshade, the 100s of tiny pieces of tempered glass would have rained down onto my head and body while I was driving at highway speed. The sound was EXTREMELY loud, like a gun shot or bomb explosion. For a moment, I literally thought someone had shot a gun at my vehi…

Owner report 11553160 · 2023-11-02 (November 2, 2023)
I drove the EQS without issue for six months. Then, about a month ago while I was in reverse backing out of my garage, the car slammed on brakes and the seat belt forcefully engaged. It felt as if I hit a brick wall. There was nothing behind me--nothing in the driveway. Then last Sunday, October 29, 2023, I was at a stop light and began accelerating down an off ramp. Nothing was in front of me; however, the car slammed on brakes again--with the selt belt forcefully engaging, and I came dangerously close to getting rear ended. My husband turned …

Owner report 11588360 · 2024-05-13 (May 13, 2024)
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 …
