Well said. Yea I am lucky my warranty is still good for another 16 months, but I am worried this won't be the end of this matter. After dropping the truck off I didn't hear back for almost 2 days so I called in to follow up and this is what they told me, "Needs lifters and cam". Seems odd for a lightly driven truck and only 69,000km I will let them repair under warranty, and try my best to get something out of GM on this one moving forward. Any suggestions or words of wisdom?
