Air Brake Disc Caliper problems of the 2004 Ford Focus

3 months after buying a 2004 Ford Focus lx, the brakes and calipers had to be replaced. Approximately, 3 months later again. Then again 5 months later but yet to include my rotors were destroyed. Everytime I ahve complained that this shouldnt have happened and the dealerahip acted as if everything would be ok. I was in a small accident during this time because my brakes completley gave out. I was the only person involved in this accident. My front bumper is messed up becasue of this. All of these parts have been replaced everytime!!I have spent over 400. 00 dollars in rentals ahving to drive them while my car was being fixed. Im sick of having to constantly have the same problem corrected. I don't know what else to do. My friend drives a Focus and had the same problems. Hers was returned immediately when she found out how many times it happened to me. I cant return my vehicle until damages are fixed, which I don't feel is my problem. I would never reccommend this car, and try not to drive it in fear im going to hurt myself or another.
