Brake Disc Caliper problems of the 2009 Acura TSX

I have a 2009 Acura Tsx, the brakes keep prematurely wearing out and having to replace them ever 12-15k miles, I am already on my second set of brakes for the rear, dealership states that this is normal wear and tear on vehicle and I disagree, canada put out a service bulletin about their rear brakes and replace the pad and calipers. Accords in the same year have the same problem, premature brake wear. Inside wears faster than outside as well. This is an unnecessary expense and annoying.

Normal driving, rear brakes worn out prematurely. Oe brakes worn out at 13600 miles, replacement brakes are currently being replaced at 35300 miles (I am currently at the dealer). Rear brakes are wearing out on the inside pads. Possible caliper issue. Front brakes are wearing normally. Recall has been issued for canadian models of this car, us models are yet to be recalled for this same issue. Honda accords have similar premature wear issue. Honda is yet to acknowledge the issue formally even though a complaint has been made. So far I have spent $250 (first time) and $200(second time) to get rear brakes replaced under 35000 miles. History of car: bought Tsx in October 2008 (2009 model), first set of pads replaced in April 2009. Second set in March 2010.
