Washed truck about week ago. Took to dealership on 10 Feb for Oil change and tire rotation. My rotations are free. I also always have full synthetic put in and I hand them a Good Synthetic Oil Filter. ALSO had major issue truck running too hot: running 217-227. I did use my scanner and found no codes. Dealer said: Electric Fan not working properly (no chit sherlock), and ordered new fan for truck. Truck is early build Apr 2018 (VVT setup), and has 19K on Odometer. So awaiting new fan for truck. Since I have Maxcare warranty, just be $100.00 payment regardless, works for me. Gonna be first time use of Warranty after 3/36000 expired.
