2023 MERCEDES-BENZ EQS450+

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 vehicle. I was extremely fortunate that I was able to maintain control of my vehicle, as this sudden explosion could’ve easily caused me to lose control and crash.

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 creates sudden deceleration in the car and slow down as well as on the left lane traffic where there was a following car behind me with high speed. 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 🔴 Wrong speed sign pops up on the dashboard 🔴 Confusing warning sound 🔴 Speed sign Indicator acts like inconsistent or confused by changing from 30mph to 45mph or vice versa.

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.
