I own a 2008 Chevrolet Impala LT that I purchased in Feb 2009 ever since I have had this car I have experience wheels/tires vibration while driving. It has been back to the shop at the dealer three times for alignment on tires. This last time I was told that 3 tires and rim are out of round and that I will need to purchase new tires and rim. My car is still under warranty and the dealer/Chevrolet should replaced them at no charge to me. I am very dissatisfied and would never purchase another car from this dealer or a Chev. Impala. read full review »
