Carrier/rack problems of the 2016 Volkswagen Passat

My 2016 Volkswagen passet se model car applies the brakes while in motion on its own. This has occurred 6 timed over the past 7 months. I bought this vehicle on December 12 2015. It is getting worse each time. One time it happened as I was about 100 feet from a intersection. No one was in front of me. I was the only one on the road at the time. I was during the day and then all of a sudden the break applied. Really scared me. Another time it happened approaching railroad tracks. This time the brakes applied really hard. It was bad every thing flew around the car. A couple of times I heard a beeping noise. Like a warning beep. There is a illuminated car on a curvy rad on the dash when this happens. This is a very dangerous car. I am afraid this will happen when I am driving at high rates of speed. I have contacted vw about this issue and they do not seem very concerned. I am shocked at there outcome. It has been in the shop for 3 weeks now. I took it in on June 22 2016. They want me to pick up on July 12 2016. It has been there 3 weeks. I am very afraid of the vehicle please help me with this issue. Like I said earlier in this note. It has happened 6 times and will continue to happen. Vw told me that it will continue to happen. Please make them recall this issue.
