I had numerous problems with this vehicle (almost through my third set of tires, oxygen sensor going at 46,000 miles, rust beginning at 38,000 miles {car was two years old}, and the battery going prematurely). Last week, I attempted to put on my rear defogger. The light came on, but my rear windshield was still fogged up. The defroster also does not blow cold air if the car is in park.

My 2007 Impala tires wore out prematurely. I noticed the tires starting to wear out on the inside at about 6,000 miles and had the tires aligned and rotated. The tires continued to wear out on the inside. I brought this to the attention of luck Chevrolet at about 32,000 miles and they said GM would not cover this repair under the warranty. However they did say there was a problem and a kit could be installed to correct. I replaced the tires and had Goodyear install the camber kit to correct the problem. I spent $800 for new tires wheel alignment and the camber kit.
