This site is working on reliability data for all cars since 2003, but there are only a few mazda (3) owners who have listed their cars , so if you could list your car there! I just did, and I think it will help to show just how reliable and well built our cars are!

Exactly which Mazdas are you refering to? The RX7 ?
