Driveshaft problems of the 1998 Kia Motor Sephia

I bought the car with 7000 miles on it, it has needed 4 brake jobs (every 7k -front then rear then front then rear) in the 28k that I've owned it. The rear brakes do not engage so the front brakes wear out. I had it put on a rack and someone step on the brake pedal, the rear tires could be turned easily. With strong pressure on the pedal, the rear tires were hard to move, but still could be moved by hand. The 2x the rear brakes were serviced, the cylinders had cracked and leaked. A friend has suggested this means the hydraulic pressure is going into the cylinders but they were a 'bad casting' and the pressure isn't pushing the pistons out, but eventually causes them to crack. 09/18/00 a flexplate in the transmission needed to be replaced. Less than 6 weeks later, the car went out of gear as I pulled into an intersection. It could not be driven. It was towed to the dealership and they replaced the transmission, drive shaft, and front axle on the car.

Since the time that I have purchased this car it has been falling apart. The car is constantly shutting down or it just won't start. At this present time my car is sittting at stonemountain kia whereas it is in need a third battery all within less than a years time. Eventhough they know the dangerous history of this car that I purchased new, they continually return the car to me without doing a safety check. I have had my car towed to their location several times in the same week because they have felled to fix the problem. Once again my car is continually suffering from the same problems that are continuing to grow worst. The air conditioning system fails to work properly. The driveshaft is always sticking in the gears. The air bag light continually blink and stay on for periods at a time. The exhaust still making loud noise that I have complained about since I brought the car. The engine jerks and the car is burning a lot of gas. The battery acid continues to leak out into the car. The air vents broke just from a slight touch and so did the knob that control the air circulation. The car is constantly stalling. The car shakes badly when pressing on the brakes. Firestone refuses to work on kia's because they are aware of all the faulty system pertaining to kia's. Lation.
