Owners/service Manual problems of the 2017 Volkswagen Passat

I own a 2017 Volkswagen Passat sel premium. One of my primary concerns is that the autonomous emergency braking system does not function according to page 271 of the owner's manual, or as promoted by their dealers, and in tv commercials. I took my Passat to two dealers, both supposedly checked it and said it tested 100% a week later, the car did not slow at all when I was close to a vehicle in front of me going 65 miles and hour and it slammed on its brakes. If I had not been paying attention, a serious accident would have occurred. I wrote a letter regarding my concerns to mr. Hinrich woebcken, ceo of vw of America. The response from vw was that my system works fine according to their dealers, and they will do nothing further for me! after that, I did some research and discovered the results of front collision prevention testing that was done by the insurance institute for highway safety. Their tests on 2017 cars included those of over 20 manufacturers. There are 3 different parts to the test: forward collision warning (on the Passat this is a two car symbol in the instrument cluster) low speed auto brake (this is for speed under 12 mph) high-speed auto brake (this is for speeds over 25 mph) the results of these tests shows that all comparable manufacturer's sedans either scored 2 or 3 points on the high-speed auto brake test. However the vw Passat scored "0" points, and was unable brake the car or reduce the car speed at all! the 2017 vw touareg also failed the high- speed auto brake portion of the test. I feel that vw needs to inform owners, and stop advertising that their cars have a functioning high-speed auto braking, as they do not! they should quickly come up with a fix, and recall all 2016 to 2018 Passats, and other models that have this faulty system! drivers have a false sense of security for a system that does not work!.
