I have 2012 with almost 90,000 miles now and the only issue I have had was an exhaust leak at the manifold at around 60,000 miles which was covered under the powertrain warranty. I changed it up last year and put a spindle kit on it with 35's to try to get rid of the urge for something new. All and all its been a good truck for me but I only get about 14MPG now tops. Best MPG I ever saw with this truck was going to Vegas when it was stock and would see close to 20MPG. I do not have the 8 speed trans though. Enjoy it I think you will like it.
