Brake Light On problems of the 2011 Volkswagen Jetta

When I purchase this car 2 days after I purchase the brake light came on flashing the car idles too high what could be wrong with it.

Car would not accelerate properly, requiring the pedal to be completely depressed to achieve any acceleration even to low speeds. At this point, a brake warning light appeared for the first time. Vehicle was brought to dealer, jim ellis vw in the atlanta area who tested the model and determined the abs module had failed. After replacing the abs module the brakes locked during a test drive by the service staff. Subsequently the brake booster and brake master cylinder were replaced. Owner believes that this early failure of so many components on a newer, very low mileage vehicle likely represents manufacturing defect and could have resulted in serious injury.

Brake light started to flash every once in a while. Brought my car into the dealer and the master cylinder was leaking into the vacuum chamber. No leaks on the ground as the leak was contained in the vacuum chamber - I was slowly running out of brake fluid. The dealer found the sealing surface of the master cylinder was not smooth - they figured it was leaking from new. Shop replaced master cylinder and vacuum chamber under warranty.

I purchased a new Volkswagen Jetta 2011, it has 3700 miles on board, during my trip to work (my speed was about 35m/h) before the intersection I tried to brake on red light, and my brakes did not work, they just stopped working, I pressed brake pedal 3 times till it began working again. I passed the intersection line and fortunately there was no any cars in front of me and very fortunately my speed was low. What could happen if I were on highway? that event happened after 3 days I passed service check at dealership. My car was towed to dealership and it was checked. After I was called for test drive and they were convincing me that everything was fine with the car, computer really showed 0 problems. I did not want to pick up my car and asked them to test the car till the problem appears again, because I think that is very major problem. In the end the problem occurred, and they realized that the problem really had place. I was given a report from Volkswagen service and I saw that the cause was: internal failure at brake master cylinder, so they replaced: 1 master cylinder, 2 brake fluid and 1 gasket were replaced. It means that car really had a problem in spite it is new. Now I am afraid the same problem not to occur again. I am trying to replace the car, but Volkswagen does not do that, they tell me that the car was repaired under warranty. Now, when I am driving that car, I always try my brakes, before intersection, on highways and everywhere. I do not want to drive that car anymore, I always think that the same problem may occur again and it can cause a real accident.
