My car started shaking at speeds of 15 to 20 mph and pulling hard to the right. when i took the car into the dealership they informed me that i must have "hit something at a fast speed because my rim was severly bent. then they proceeded to tell me there were several other problems wrong. the car was almost at 48,000 miles. i paid out of pocket, simply taking their word for it. then i kept losing air out of another tire on the opposite side. at this time i figured it was the tire that i purchased a few months earlier. i had the tech. take a look at it and he showed me that there were several cracks in the rim which were allowing the air in the tire to leak. once again i bought the car to the dealership where i had to spend another $230 to get a new rim. i have had several cars in my life and never once had to replace one rim let alone 2 and in a period of 2 months. i think someone needs to look into this. this is not only expensive but extremely dangerous. i think that the manufacturer should have a recall on these rims and refund the customers that had to pay out of pocket.*ak
