Interesting that you had Distronic cruise on as this is one of the things that MB wanted to know if we engaged. We were not using the Distronic system during our accident. Just trying to stop with a good old fashion brake pedal.

Thank you. I am super afraid as for my family. Though I felt the issues prior to accident were things that MB could hopefully be fixed but that seemed not to be always be the case as the vehicle was in and out of the service department. I had requested from the very beginning a case to open for MB to classify the vehicle as a "lemon" then the accident happened and now I refuse to drive it or put my family in harms way. I have yet to hear about the diagnostic report though I have requested three times where as the service department expresses nothing or tell me they cannot do anything without MB approval. If you could hear me speaking to Mercedes SOS, she just kept telling me to breathe.

I’m sure you have probably read other threads about this, but I had pretty much the exact opposite experience in my 2018 S560: While driving down a somewhat rural, two lane road, with not another vehicle anywhere in sight, while probably going about 40mph, the car slammed on the brakes. No animals, nothing that I could see crossed the path of the car. Took the car into the dealer, but everything checked out perfect and the car never did it again. Scared the heck out of my wife and I when it happened.

when I became afraid of my car is when I started discussing lemon law. I am so sorry that this has been your experience as well. Hopefully your car will report "the event" as mine did. At least with all the tech on these cars they can report errors instead of poor techs trying to recreate occasional and dangerous blips. I hope you can come to a satisfactory resolution.
I cannot remember which stationary objects the W222 would ignore it intentionally ignores some. Otherwise at high speed it would be braking all the time if prepared for the driver turning the car quickly. I would assume both taking into account stationary objects that are on the current direction of travel although even there it would need to be pretty late, possibly too late to fully avoid an accident. An example on my neighbourhood where a straight road turns significantly just before a T-junction. The car alerts for the traffic sign in the middle of the road but does not brake.
This onebigfamily53 case is discussed on multiple threads, I'd avoid it here, one thread is enough even if the owner feels it deserves the whole forum.

One day I thought I would test the car's (W222) ability to detect stationary automobiles up ahead. While on Distronic cruise at 65 mph on a 4 lane highway with occasional intersections and traffic lights, I approached the stopped cars at the traffic light without touching the pedals just to see how fast and far up to the cars my car would go without intervening. I had to quickly slam on the brakes or else I would have plowed into the stopped cars. The advertisement on most YTube videos show the latest Mercedes S classes going back at least a decade to intervene and prevent a collision. The demo shows a cardboard man suddenly walking out in front of an oncoming Benz and the car detects the "pedestrian" and even at high speeds the car manages to stop. My experience is that it only slows down when I'm trailing a car in motion, not at a standstill. Not confident to trust it 100%, not even 50% .

Based on my original post on the thread I started...I am a newbie to this forum and I do believe I have replied to all comments. I selected quick reply thus just shows as a general reply so now I think I have figured out how to reply to the comments even on this thread. On particular post I was responding to the OP as her vehicle and our vehicle have very similar issues where as our vehicle was having these similar issues prior to accident (brake failure) I do not believe that my post warrants two threads either, again I just commented on the OP post.
As I posted in my original thread....I really do appreciate all the comments honestly as I would never in my right mind think this situation would happen as I know MB strives on safety. On that note. I have asked about the EDR, the diagnostic reports (pre and post accident) as I have yet to received any type of information from the service department and/or MBUSA. Recap. I was not using Distronic's, I was not relying on the intelligent drive system, I am merely trying to find out more information as why certain aspects of that system would not have engaged based on reviewing several reports by MB. I was paying attention to driving along with the truck in front of us. I was not using a phone. I am familiar with grid lock traffic and kept the vehicle a good distance where as I should have been able to stop without incident. I did actively apply the brakes (hence why brake assist did not engage per MB) I pumped the brakes and push down as hard as I could and the actual brakes did not stop the vehicle. There was not anything hindering my use of the brake pedal (shoes or extra floor mats). Upon impact our vehicle turned off then back on, I actually have a photograph of code that came up to support this. I have several CCTV videos (pre and post) accident that reflect the vehicle doing odd things along with photographs of error codes. With that said, the vehicle has had issues from the day it was delivered to our home of which I was not made aware of as the sales person cleared an error code prior to my test driving. I have been dealing with the selling dealership and MBUSA on classifying the vehicle as a lemon prior to the accident. Side note, our previous vehicle 2020 S560 was awesome, I made a decision to purchase the 2021 S580 after I saw all the upgrades. A decision I now regret. We did not have any issues with S560 believe me I would love our previous vehicle back. I am really terrified of our S580 and refuse to drive or be a passenger. I will not put myself and/or my family in harms way due to what happened. Most of the comments are valid points to make and again I appreciate all the feedback. Just trying to understand. Thank you again!

I actually turned that 2018 in last year and got a 2020 S560. No braking issues to date with the new car.

Had my 2021 W223 for a few months now. Last month, I was driving about 15 km/hr in a one-way street. A man was standing in the pedestrian walk about 2 metres from the kerb. As I approached him, he walked toward the kerb and stopped right there, probably to hail a taxi somewhere behind me in the traffic. My car must have sensed him as the ''cardboard running man'' (as the one in the MB Youtube demo) about to run in front of the car and so applied brake suddenly and harshly, making a very loud noise. The noise must have come from the braking but it sounded very much like the car hitting something (or being hit by something). The car stopped abruptly, of course. At that point, he was standing on the pedestrian walk edge, about 1m from the car bumper. I went out to look around the car and found that I had not hit anything. Very fortunately, the car following me was still very far away and so did not rear end me!
I am now thinking of disabling this Active Brake Assist.

Just remember, this is an emergency feature. You don't want it operating early, or it would operate all the time when you as the driver would normally brake, its designed to operate when the car has determined its too late for you as the driver to intervene.
