I would suggest you read the details about WARRANTY and brakes and if you don't understand contact MAZDA direct and ask them. It is not as cut and dry as you are posting. Brakes specifically!
Mazda Warranty Information | Mazda USAEvery new Mazda comes with a limited warranty that provides coverage in the unlikely event a repair is needed in the first years of ownership.www.mazdausa.com
We get at least one customer a month having to do with a new vehicle that the warranty coverage outlined like Mazda did not cover their brakes because it was determined not a defect and normal wear.
That said nothing in this thread has yet to point to a defect.
