Entirely possible! Your personal driving style combined with engine power, sophisticated traction control systems, and the braking system on the vehicle itself can all contribute to fast(er) wearing brakes.
If you're unsure of what you've been advised regarding your rear brakes, get a second opinion.
Actually I am working in reverse. My regular mechanic is advising I need rear brakes, I am now bringing it to the dealer. I took a demo with 2200 miles, which now has 19,500. I was told at delivery new brakes were installed. ( a little difficult for me to believe). So now my complaint if they tell me I need brakes also is that these only have 17,000 miles. Again, I just thought this was very premature.
yea its possible because the rear brake rotors are way undersize for the weight and horsepower of the car, my wife is the only driver and she doesnt drive fast at all. we are getting brake judder during hard braking sometimes but it feels like the rears to me, not the fronts take a look at the size of your front rotors then look at the rears, they are supposed to be smaller but thats ridiculous 40 k carand replacing rotors at 17k mi, thats bullcrap
