Check engine light came on and was related to the turbocharger not communicating with the computer. Took it to the dealer and found out the actuator needed to be replaced at a cost of $3000.00. Fortunately the turbo was not damaged. I had it replaced since I pull a trailer. Only have 70,000 on it. Unbelievable. I am going to sell the truck. Had a lot of other issues too.
