Alternator/generator/regulator problems of the 2000 Mazda 626

My 2000 Mazda 626 began having problems a week after purchasing April 10, 2008! the car started having electrical problems which resulted in 3 batteries, 2 alternators, no ac or defrost could be run. Then the brakes were replaced twice within a 2 month period! all these problems resulted in me almost being killed from an automobile accident! this happened June 8, 2009 which was a Monday approx. 4 pm. The airbags never deployed, and my head hit the steering wheel. Windshield shattered all over my hand resulting in severe lacerations! this car needs looked at ASAP!!!! please help.

Engine check light and battery light came on, came on five times, the first time dealer replaced broken idler pulley belt bolt, second time dealer replaced alternator, third time dealer replaced ignition switch, fourth time transmission range sensor was replaced, and fifth time clutch pedal switch was replaced, at this time engine check light is on again. Consumer states when the vehicle was driven off the lot the first day, there was a horrific screeching noise from the right front wheel, consumer assumed that it was a new car noise and it would eventually go away, consumer was inforemd that something had slipped in the wheel area, over the next two weeks consumer complained to the dealer that vehicle was making an extremly loud thumping noise, the problem was diagnosed as the freon system which was then flushed and then refilled to the correct level, which was done to take out the air bubbles in the air condition line, also the air condition was blowing hot air, the center console would not latch, numerous componets were replaced on the vehicle due to the engine light coming on and the problem still exists.
