1. my car is 2007 toyota matrix, before my first accident i took my car twice to be inspected by the dealer shop at fitszgerald because i had two brake failures while riding to my house and both times they blamed on the floor mats, and the second they gave me a report saying that they were unable to find a failure on the brakes after inspecting it for 96mile drive, they found nothing and put on the report that the vehicle had no problems. i was driving on the highway during a high traffic, the vehicles in front of me slowed down, i stooped then when the vehicles in front started to move i let go of the breaks and suddenly the car went out of control and hit the car twice while i was pressing the breaks. 2 this happens not often, this happens when i put the car on park or i slow down, usually when i apply the breaks. i am afraid because they can't find anything wrong with it or that they refuse to help me. for this even my premium car insurance went 200% 3 nothing can be done because they don't know what's wrong, i am at a loss because is difficult for me to find any help.
