My 2013, 158k, came up with an engine code that said it had bad A/F mixture. I took it to the dealership and they said it needed a new cam and lifters. It's covered by the extended warranty. They did the work. I picked the truck up and drove it around town for a couple hours. Before I got home, the engine light came on again. I looked up the code and it was for low oil pressure. I took it back to the dealership and they said its going to need a new engine. They had it for a week trying to get it approved. It was finally approved and now I wait for the new (reman) engine to arrive and then 2-3 days for it to be installed. Lots of prayers and waiting, but hopefully this new engine will last me another 5 years. Thank the Lord I got the extended warranty!
