At less than 10000 miles reduced power and check engine light kept coming on about every two or three weeks. I called the dealership and waqs told that I would have to drive it in with thr reduced power on for them to find the problem. As I write this the truck is under the garage and will not start. Put in new battery and stil nothing. Will call dealership tomorrow and have it towed to the shop. Very disappointed in a truck that's only a year old. Never know what going to go wrong next.
