I had the 45000 done and they replaced the rear brakes and put two new pilot a/s on the front, said they were worn because i was out of align...the rears were fine they said. got it back and the tires are loud...put it back in the shop and they checked it out and said there was nothing wrong, just an "agressive tread pattern." I did not have this road noise when I put 4 new pilot a/s on a year ago I'm thinking someone can give me some insight? I can really be certain but it sure sounds like the rears
