I had purchased a 2010 Chevrolet Impala in July, 2010. The first attempt at repair of the front end vibration was on 10/22/2010. The dealership did not recognize the vibration. The vehicle tires were rotated on 01/26/11 in an attempt to stop the vibration in the front end. The vehicle was taken in on 03/18/11 for front end noise (thump) while turning the wheels. The vehicle was taken in on 07/07/11 for the thumping noise in the front end while turning the wheels. The vehicle was taken in on 07/28/11 for a front end thumping noise when turning the wheels. The vehicle was taken in on 08/16/11 for a front end thumping noise and the dealership notices the tires were wearing slightly cupped on the inside edge. The vehicle was taken in on 09/08/11 for a whining noise from the engine bay and power steering fluid was flushed. The vehicle was taken in on 04/09/12 for front end thumping noise, wheel bearing, transmission surge, and whine noise from radio. The vehicle was taken in on 06/27/12 for rough idle, tire replacement, transmission. The vehicle was taken in on 07/27/12 for rough idle, transmission surge, thump noise in front end and whine noise in radio. The vehicle was taken in on 10/05/12 for transmission surge, rough idle, thump noise in front end, and whine noise in radio. The outcome at this point is the dealership tried to reprogram the vehicle, GM approved replacement of all four tires, a replacement of the power steering pump, wheel bearing on driver front side. The dealerships have done two throttle body cleanings. The dealership has stated they will replace the rotors but GM would not approve replacement only turning on the rotors. This case has been opened with the better business bureau whom advised me to contact NHTSA. GM refuses to replace parts because their computer system cannot tell them what is wrong with the vehicle. GM has recalled the police vehicles for front end suspension and has a lawsuit pending in Michigan for personal vehicle.

Took 2010 Impala ltz to have oil changed and tires rotated. They found the front tires to be worn badly on the inside of each tire. The driver's side had much worse wear with the steel cords visible. We bought the car from a dealership with over 10,000 miles on it. It now has 19,000. In an online search, we found that the car had work done on the steering before we purchased it. It still has a problem with a growling sound in the steering at times. Could that effect tire wear?
