Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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. …”

“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. …”

NHTSA complaint #11528510, filed 2023-06

“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. …”
