I purchased car new and when slowing to stop the car shut off 4 different times. It would start back up ok. When starting off transmission slipped 8 times. Starting about 20,000 miles you would hear a clicking sound/bump when you backed up and started off. I went back to the dealer about 10 times trying to get these things taken care of. They would drive the car and say they cannot find anything wrong. Asked them to put all info in the computer. At 35,000, bad rotors, 43,000 bad tire rods, they paid for both. About 80,000 miles replaced Intermediate steering shaft my cost. Driving 2010 Toyoto Camry now. This was my 6th Chev. Impala and I will never buy another Chevrolet. You Decide.
