I had a brake failure and immediately drove to the Mazda dealership which happened to be about 1/2 mile down the road. They checked the car completely and told me they could not find a problem with anything related to the brakes. While there another gentlemen head me and said the same thing happened to him about the same time. Later that day I found out that a third person also had the identical problem and on all three vehicles they could find nothing wrong. I'm wondering how many other Mazda owners have had the same problem. My car was an 06, one of the others was an 06 and I'm not sure about the third. I did not talk with her direct. My car is automatic and the other 06 was stick shift. Three of us in one 2 hour period is too much of a coincidence for me. There must be a problem of some sort.
