Front Suspension problems of the 2006 Mazda MAZDA3

I had gotten a flat tire after hitting a pot hole and knew that I was going to need new tires shortly anyways so I had them put on a used tire to get me through two weeks and while during the two weeks I was gone for a few days and had new breaks put on and asked them to just double check to make sure there was no other damage- there was- a busted strut on my front passenger side (side that I got a flat). I waited until I got home from a vacation (car wasn't driven) and got that fixed but everyone was surprised with the strut being out. All 4 tires were replaced as were both front struts. Car was great for ~2 wks. Then it was loud and terrible vibrations. After arguing and complaining a month later they replaced tires for me because two weren't even keeping tire pressure and then I remembered that a few months prior I was at the Mazda dealership (where I really can't stand the jerks!-they're awful!) and they said I had a busted motor mount but refused to show me. I had my main dealer check it out but they found nothing then a family friend, but again nothing. Ff to December and I give in and go back to Mazda- motor mount would be in multiple pieces if it wasn't in a capsule like device. In January they got my part in and replaced it- also knocking out a stopper- and vibrations stopped. Mount shouldn't have gone out so fast- at initial dx I think car was at 45k-50k miles (late summer of '10) I think there's a defect with mounts (mine was passenger side over tire area) and also with struts. Everyone has told me- Mazda, my dealer (zimbrick-who is absolutley amazing!), and a few other service centers that the struts should've lasted a lot longer.

2006 Mazda 3 front tires rub and wear uneven. The car cut a deep gouge on the inside of each front tire.
