Vsa Warning Light On problems of the 2010 Chevrolet Silverado 1500

Driving 65 on cruise control when check engine, stability control lights came on. Message center said reduced power I got to a small service garage and he told me I should shut it off wait 15 minutes and it will reset and it did. I drove another 80 miles again the same thing happened. The first garage guy told me it was a gm issue and I should go see them they should repair it. He said it was a problem with the throttle body assembly and in the cold it get sluggish and gm should fix it because they had problems with some of them. It happened again 20 miles later. I got back to the gm dealer where I purchased it he confirmed it was they throttle body assembly but didn't have time to replace it. He offered to clean it (free of charge) and sent me on my way telling me if it happened again I should make an appointment to replace (approx. 400-600 dollars). I done some investigating on this matter and found this was a common issue. I stopped at another gm dealer and explained my problem he confirmed the original theory checked the VIN # and told me gm is fixing this problem for 10 years from the original purchase date. I guess I need to stop buying from my original gm dealer where I had purchased my last two vehicles. I have not had a problem with it again but I have only driven 600 miles since then.
