The rotation of the rear passenger tire is causing a scraping noise to occur. It is more obvious when the car is cold and even more so when it is humid out. I have taken it in 4 separate times, making a 100 mile round trip to do so. After leaving the car with the dealer for anywhere from 3 days to 2 weeks, I was told that nothing was done because they never heard the noise. Every person who has been in or around the car has heard the noise. IT'S EMBARRASSING. Now it's worse than ever and even after the 4th visit for the same thing, they continue to tell me that they cannot tear into it so they can't do anything about it. They say that they can't tear into it unless they can justify it to the warranty company. Two machanic friends of mine can see grooves being worn into the rotor without even taking the wheel off. I guess I can only go to a higher up. Or, go right into the garage with it and point it out to them myself.
