So update on truck is Dealership found water stains and small amount of something in the intake. They said it is water but I don't go off roading with my truck, I have a side by side for that. Also it hasn't rained here in a few weeks. All in all the dealership says it's not covered under warranty. This is exactly why I didn't take it to them without seeing what was wrong with it myself. I did see water stains but there are water stains in the entire engine compartment. I found no water inside the intake and the oil was perfect. Changed 1 week before. So now my insurance company is involved. Anyone known if there is anyone I might be able to call with GM to help?
