Suspension Noise problems of the 2011 Mazda MAZDA3

I am writing to inform you of a known rear camber issue on the rear suspension of the Mazda 3. The rear wheels on Mazda 3 tilt inward at the top. Rear camber alignment matched to "factory specifications" does not correct the issue, and tilt is still present - causing uneven tire wear. Mazda recommends rotating the tires to avoid uneven wear, but this does not correct the tilt. Rotating the tires according to Mazda's recommendation with rear worn tires being placed on the front causes road noise issues. I just purchased my vehicle and was told, "this is how the Mazda3 was built to assist in road handling. " the rear cambers of the vehicle are non-adjustable. If they were adjustable from the factory, Mazda could resolve this issue. I am upset because I will have to purchase tires much more frequently now that what is considered standard - on vehicles that are able to be adjusted so that the camber is at 0â°. This is a known issue, and Mazda is aware of it, but will not take responsibility to correct the problem. After researching this issue, I discovered hundreds of other Mazda customers dealing with the exact same issue.
