The transmission started slipping in 1st gear, not moving off the line sometimes at stoplights. Then the slipping started in 2nd gear. Took it in, and they had to replace the transmission due to a known defect. This is a ridiculous issue to have at 32k mi, especially considering it is a known defect. GMs QA has seriously deteriorated, and yet they wonder why they continue to lose market share to Japanese automakers. Do yourself a favor, don't buy a GM
