SERVICE BRAKES

2 injured · crash · towed

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.

NHTSA complaint 11731921. Filed by an owner and not verified by NHTSA or by us.

SERVICE BRAKES

2 injured

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 no control or indicator that the braking was going to automatically brake on its own. The problem has not been reproduced or confirmed by the dealer

SERVICE BRAKES

1 injured

At approximately 10:30 p.m. on January 8, 2023 I, and three passengers (my wife, and another couple), were completing a one hour drive returning from an event in southern California. We traveled on the freeways as we headed home. The speeds on those freeways average between 65 and 75 miles per hour with the flow of traffic. I exited the freeway and pulled up to a traffic light. I made a right turn at the light, then traveled up the road. The weather was clear and dry, and there were no cars either behind, in front of, or beside me as I drove up a cleanly paved and level road at a speed of approximately 35 – 40 MPH. During the drive up the road, the car inexplicably and suddenly stopped,

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

1 injured

This afternoon, while I was driving on freeway at a normal speed (75 miles/hour) with an ample distance (30 feet) from the car in front of me , I suddenly felt a huge impact. It was so violent that I immediately thought my car was hit by the car behind me. I stopped the car on freeway and called 911. But from the back mirror, I did not see any damage on the car behind me. I got out to inspect my car but did not see any collision damage. According to my online search, this model - Mercedes-Benz EQS - has a frequently reported issue of "Phantom Braking" from the Forward Collision Avoidance System. It was very startling and dangerous experience for me. Now 5 hours later I still feel the pain

NHTSA complaint 11702392, quoted in part. Filed by an owner and not verified by NHTSA or by us.

ELECTRICAL SYSTEM
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

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

8,000 miles

The contact leases a 2023 Mercedes-Benz EQS450. While driving at 35 MPH, the vehicle unexpectedly stopped with no other vehicle or object nearby. The vehicle was taken to the dealer on several occasions; however, the cause of the failure could not be determined. The contact was informed that it was a common failure and that other vehicle owners had sustained injuries due to the failure. Additionally, the contact stated that while driving 10-15 MPH and approaching a red traffic light, the failure recurred, almost causing the vehicle to be rear-ended. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage

NHTSA complaint 11716672, quoted in part. Filed by an owner and not verified by NHTSA or by us.

ELECTRICAL SYSTEM
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.

NHTSA complaint 11707193. Filed by an owner and not verified by NHTSA or by us.

SUSPENSION
Two weeks ago, I returned back from work and later on in the evening was driving to go to grocery store when the car seemed to get pulled to one side and started shaking when driving around 40MPH. Not knowing what was going on, I turned back and slowly drove it back home. Next morning, I thought may be there is low tire pressure ( even though it was in range), I slowly drove to get air filled. After that coming home the car started pulling on the left side and shaking around 40MPH speed. So I slowly drove it back home with flashers on and then towed it to the dealership not knowing what was going with it. Car has only 6700 miles on it. Dealership looked at it and said that the left rear

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
