Just turned 85k on my 14. So far the only bad thing to happen to mine has been the AC condenser. I bought the extended warranty and it was covered. It has rattles and squeaks in the interior that I have not been able to quiet. Currently there is a bump noise in the front end sometimes that I think may be in the rack. I will see if I can this looked at under warranty also. Other than that, the truck runs great, drives great, trans is great. I do change one gallon of fluid every 15k miles. Change the engine oil every 5k. Rotate tires every 10k. Changed the diff fluid and trans filter and fluid at 65k.
Knock on wood.
