While making a left turn at low speed, I applied the brakes, but the vehicle did not respond as expected and instead appeared to drift, surge, or accelerate forward. The vehicle struck a fire hydrant and a bus stop pole before crashing into a tree. Airbags deployed and both occupants sustained injuries. I suspect a possible malfunction involving braking, propulsion, electrical, or speed control systems. No final cause has been determined. The vehicle should still be available for inspection. Mercedes-Benz USA has opened a case regarding this incident.

Several times, the car's "panic braking" has randomly slammed the brakes and tightened the seat belt. After the first few times, I took it to Mercedes and they re-uploaded software which was hard for them for some reason. It fixed the problem. Luckily, I had always been on small streets. But today, the panic braking happened again, only this time, I was on a major road (4 lanes at 35 mph) and, with nothing around me, no cars in front of me, the panic braking and seatbelt tightening happened so violently that I was thrust forward with enough force to hurt my hip. Nothing severe no doctors needed. I will take it back into Mercedes for another review but what if there had been someone behind me or I hadn't been wearing my seat belt. I would have been hit hard or gone through the windshield. (I was wearing my seatbelt and always do). This has happened at least 5 times since I've owned it.

On the date of purchase, while driving approximately 50 mph, the vehicle’s hood opened unexpectedly, obstructing my visibility and causing the vehicle to leave the roadway and enter a ditch. State Police responded, and the vehicle was towed immediately. This incident presents a serious safety defect. The is vehicle is certified by Mercedes Benz and purchased from Mercedes Benz Dealer.

I am reporting a serious safety issue with my 2023 Mercedes-Benz EQS SUV. On multiple occasions, the vehicle has suddenly lost power and completely stopped while driving on the freeway without warning. During these incidents, a red warning symbol appeared on the dashboard (a red turtle icon), indicating a critical malfunction. These failures created extremely dangerous situations, as the vehicle lost the ability to maintain normal driving speed in active freeway traffic. At the time of these incidents, my three children were in the vehicle, which significantly increased the risk of a serious accident. This issue has occurred multiple times, suggesting a serious and recurring defect. The sudden loss of power combined with dashboard warning signals presents a major safety hazard and could lead to severe injury or fatal accidents. I no longer feel safe operating this vehicle and request that this issue be investigated as a potential safety defect.

The vehicle throws a “charging fault” error when I try to charge my vehicle with a high speed charger. I tried two different chargers and two different locations with the same result. The safety risk is a faulty high voltage battery system. I have not taken it to the dealer yet. This just happened today. My understanding is that this is a fairly widespread issue and MB is denying all warranty claims and blaming the charging station. The only warning is the “charging fault” message on the dash display.
