Already went through similar issue with my ride. Contacted GM customer service and got a real nice lady on the line. The conversation took awhile. End results where all dealers are privately owned. Had the CAI filter been purchased through a GM accessories dealer GM could make them cover these cost. Mine too purchased from shopchevyparts.com which is GM parts wholesaler. The dealerships in my town charged $60.00 and they installed filter also. They said what was paid for in price of filter was tech line charges for programming updates fee specifically for your VIN #/program
