While driving the speed of in town, stop and go traffic, my brakes failed to work. I approached a red light with stopped traffic ahead of me and started braking. I continued to brake but there was absolutely no brake pressure. It felt like my brake pedal was pushing through the floor board but nothing was happening. My car proceeded to crash into a stopped truck at about 35-40mph. My airbag did not deploy. I came away with aches and pain but fortunately was not badly injured. My car has been totaled by my insurance company. I have been telling Ford since I purchased the car that the brakes make an awful squealing noise. Finally after two years they "serviced" the brakes and then a month later this incident happened.
Brake failure, the car pulled so hard to the right it literally changed the lanes. Car in left lane had to lock up his brakes to avoid hitting me. This happened again the next day when I had to brake to avoid another car pulling into my lane. Brakes failed the car pulled to the right and I barely missed the collision. This has been going on for a year and the car has been in the shop for this 6 times. The dealer says there is no problem with the brakes but the brake tech says it is a problem with all 2012 Ford Fiestas he test drove.
