There are 11 owner-reported brakes complaints for the 2023 Mercedes-Benz EQSin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Description of Incident: While attempting to reverse out of my driveway, I experienced a catastrophic and life-threatening malfunction with my vehicle. I was in reverse gear when the car came to an abrupt, extremely forceful stop, which caused the vehicle to jerk violently forward. This sudden and unprovoked halt put me and my passenger at risk of serious injury. My foot was on the brake the entire time. As the car stopped so unexpectedly, I shifted into Drive in an attempt to inch forward. However, despite my foot remaining firmly on the brake, the car accelerated at full power, without warning, and with no input from me to do so. The car then drove directly into the foundation of my house, causing significant damage. Despite applying constant pressure to the brake, the vehicle failed to stop or respond. This malfunction resulted in the destruction of my home’s foundation and caused bodily injury to both me and my passenger. This was a life-threatening event and could have resulted in severe harm or death to anyone nearby. The car’s acceleration while my foot was still on the brake indicates a severe safety risk and defect in the vehicle’s systems, which also places others at risk.
- Emergency braking, Yes available. - It's a fatal issue. My family and I are at collision risk. - No they always say “Not duplicate the issue” -Inspected by the dealer. - the collision warning Sound went off. I was driving on the highway by speed 60 mph and no cars were behind me and the car in front of me was so far and suddenly the emergency brake sound went off and the car suddenly stopped with hard and terrified brake and all the seat belts had tightened up.
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 or independent service center because the incident happened today (Sunday) therefore, I plan on making an appointment as soon as possible to see if they can identify any defects. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others since I plan on taking it to the Mercedes dealer where I purchased the vehicle. There were NO warning lamps, messages or other symptoms of the problem prior to failure.
The vehicle pre collision automatically stops the car completely five times with no car or any objects in the front. I took the car to Mercedes dealership to see if they can find the issues, but they can’t. On 04/07/2024 I had my wife record while I’m driving and we got video of the car just completely hard breaking on its own with no cars in the front. I am worry that another vehicle will rear end me at higher speed when it does happen again.
On two separate occasions, while driving my 2023 Mercedes-Benz EQS 450 SUV, my vehicle abruptly came to a stop on the highway. The sudden and intense phantom braking caused me to experience whiplash on both occasions, even though there was no imminent collision threat. What was particularly concerning is that my car usually alerts me to any potential dangers and prompts me accordingly, but in these instances, it came to a halt unexpectedly. I reported the issue to the Mercedes-Benz of Annapolis Service Center, only to be told by my service advisor that this was a normal and preventive measure to avoid collisions. To my surprise, he even compared it to his experiences with a non-Mercedes vehicle. Strangely, this wasn't the first time I encountered such an incident; the initial occurrence was in a loaner vehicle provided to me due to other functionality issues with my car. To date, both the Mercedes service centers in Annapolis and Arlington have not taken my concerns seriously, which is deeply troubling. It's alarming that there are others like me facing similar problems, and there seems to be a lack of information on where and how to report these incidents for a resolution. The question remains: must someone be seriously injured or killed before Mercedes takes accountability for these potentially dangerous episodes? My vehicle is presently at the Mercedes-Benz service center in Annapolis, addressing various hazardous functionality issues, including phantom braking, pulsating brakes, and a range of other concerns. Once I receive the service records, I am happy to provide them for review. 1st incident:[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I had a forward collision with 2 cars. My brake has been failed and forward collision warning system failed. I leased the car because of the safety features but I am really disappointed. Since I had my kids in the car with me. It was a really horrible experience and I can't drive the car anymore because of the safety issues.
On June 1 2023 at 6:24 pm, driving at around 40 mph, the car suddenly braked hard and lurched to the left. There were no cars or other obstructions in front of the car. This braking and lurching to the left lasted a few seconds, but almost came to a complete stop. After a few seconds it resumed normal operation.
Around 5:48 pm Pacific time today, May 8, 2023, traveling westbound on Sunset Blvd (near the Drummond street intersection), the brakes suddenly engaged hard for a few seconds and then released and continued. Speed was around 35 mph and there were no obstructions around. This is the second incident of phantom braking that has occurred in 2 months. Luckily there was no car behind that could have collided into us from the sudden phantom braking.
On two occasions I was driving on city streets, 35-45 miles per hour without any vehicles nearby and all of a sudden the vehicle applied a hard brake, as if the vehicle had sensed a pending collision or something, but nothing was around. I purchased the vehicle new in October of 2022. The first time this occurred was a couple of weeks after I had bought the vehicle. I had changed the recuperation mode setting, so when it occurred the first time I thought that might have affected it. This occurred on a clear, dry, sunny day. The second time it occurred it happened for no reason at all. I had thought perhaps because my collision avoidance settings were set to the max sensitivity levels that perhaps it's seeing things that aren't there. It was very scary, it was so violent I thought I had hit something in the road, but it was a clear, dry, sunny day with no road hazards, obstacles or anything else that would have caused it. The problem has not been reported to the dealer, but I feel that when it happens again I will take the vehicle in to see if they are aware of what could be causing this problem. Nothing has been reported to the manufacturer, police, insurance or others. There were no warnings prior to the hard braking that I can recall. It just happened unexpectedly and immediately. I get a little nervous now every time I get behind the wheel because I wonder if/when the next occurrence will be.
