general problems of the 2005 Mazda RX8

I'm going in today for the third time because my ac continues to make a noise when the fan is blowing. I cant even begin to list all of the problems I've had with this car. Just to name a few I'm on my second engine, new brakes, battery and tires before 40k miles and I was told by three different shops that something is really wrong with the brakes but Mazda claims other wise. I've had a two new radiators and my driver window went out along with everything else from the visor falling off during the hot summer because it just melted. How does a "sun visor" melt. I've had the shifting paddles replaced because they just didn't work and I don't even really use them, the gas cap lock broke and I had to pry it open since the eject no longer worked. . . I think you get the point and I didn't even mention some of the bi items. I've never had so many problems with a car in my life. I cant wait until I can sell it or maybe ill get lucky and it will implode. It wouldn't surprise me at this point. This car is junk!!! I'm going back to Honda.
