Brake Electric Antilock problems of the 2005 Suzuki Forenza

I bought a Suzuki Forenza 2005 for my mother last August. She drove this car for 5 months and she didn't have a single problem. In January she was approaching a red light at the intersection and her car would not stop. She drove through the red light but it was early in the morning and there were no other cars on the road. Slowly her car stopped. 2 weeks passed and she had the same problem. About a month passed, she was approaching the red light and her car would not stop. She called me. She was crying and she told me she was afraid to drive this car. I called good year in CT and asked them to check the brakes. At the good year they could not find anything wrong with the brakes. On April 1, she was driving to her school and her car would not stop again. We took car to Suzuki garage in norwich, CT. I spoke with their representative almost every day for a week. They told me that they took a car for a test drive several times and brakes worked normally. They told me that the next time she is going to have this problem bring this car to them. I called their corporate number. I spoke with the representative first and then I spoke with their supervisor mary smith. She told me if the Suzuki mechanic cleared a vehicle then there is nothing they can do. My mother picked her vehicle on April 8. On April 13, I my mother called. She had an accident. I spoke to talk to the police officer. I was trying to tell police officer that this car has problem with the brakes. He told me that he saw a receipt from Suzuki that the brakes worked great. I told him that this incident happened 5 times in 2. 5 months. This car is only 8 months old and my mother is afraid to drive it. I feel that Suzuki failed to help me.
