Engine Clicking And Tapping Noises problems of the 2001 Ford Windstar

I have repeatedly contacted my dealer for the problems that exist with my vehicle. The brakes fail after prolonged pressure at red lights. I was told to set my parking brakes to adjust. I had two large bumps on the steering wheel. I was told that it was a broken bearing and they replaced my steering wheel and fixed the broken bearing. The new wheel has the exact same bumps. I was told not to worry about it. The air conditioner was making grinding sounds. The compressor was replaced. The enige has a ticking noise when vehicle is in gear but stopped with brake. I was tols this is the injectors and nothing was wrong. The van stalls at any speed for no reason after long periods of driving. I was told it was my alternator. I have had my van not long and already have a rebuilt new van. I went to the dealer and drove another van. None of the above problems were seen. I was told there is nothing that I could do but to trade in and pay mega bucks for another one. My van has been in the shop for 9 days the first time and 15 days the second time. I feel I have been wronged by the Ford motor company and I should be given a vehicle that I can drive and feel safe in. I feel that the vehicle has more problems then the 1980 aerostar that I replaced with this one. Please let me know if there is anything that I can do to solve this problem. If there is nothing, then please warn others from the problems that I have encurred.
