Owner report 11450809 · 2022-02-07 (February 7, 2022)
I was traveling at 75 mph along the freeway on a clear day around 2pm when all of a sudden the car's autonomous emergency braking system fully engaged and brought the car to a dead stop. there were no obstacles or impediments in front of the car or near the car at the time. It was terrifying and could have resulted in me seriously injured or killed if there had been any vehicles traveling behind me. This had happened twice previously with the car but in less dangerous conditions and at lower speeds, but this time it was much worse. It has cause…

Owner report 11494007 · 2022-11-17 (November 17, 2022)
I was driving at around 45 MPH, without any cars around me, and suddenly the car abruptly stopped. There were no obstacles or any reason for the automatic emergency brakes to engage, and thankfully there were no other cars around, or else there would have been a collision. This was a very frightening experience, and I am thankful this didn't happen on the highway or at a higher speed, as that would have resulted in a significant accident. I have only had this car 3 weeks!!

Owner report 11516288 · 2023-04-10 (April 10, 2023)
i am an owner of Mercedes 2022 EQS, living in Westchester, New York. There are a number of flaws in the auto drive software system that the company refuses to acknowledge. 1) the sensors on the passenger side of the car do not register a car immediately adjacent to you. Thus, while the auto steering feature still keeps the car within the lane, if the car to the right lane of my vehicle is adjacent to me, there is no way for the auto steering to compensate by moving toward the left of my lane to avoid physical contact with the other car if th…

Owner report 11516510 · 2023-04-11 (April 11, 2023)
the right rear tire went bald with 9500 miles on the car and no safety system notified me of low tire pressure. The left rear tire was almost as bald as well while the front tires were normal wear and fine. I believe the rear steering system is defective is the only explanation for symmetrical unusual wear. The dealer says it is normal for this car they siad the alignment was normal but the initial air in the tires could have been calibrated wrong but they do not take responsibility although the air pressure system did not notify me of low pres…

Owner report 11521912 · 2023-05-14 (May 14, 2023)
The 2022 Mercedes EQS 450 has been an ongoing dangerous driving experience for me. I have been jolted and frightened over and over as the car's autonomous emergency system fully engages when driving as well as when it does not engage when I’m stopped at a light. I have expressed my safety concerns on numerous occasions to the management at the dealership. As I am writing this I see on your website, there is an unrepaired recall on this car with a remedy not yet available. In April, 2023, the car stalled and the messages below appeared on the…
