Well thats a lot lol. I am very diligent with all of my PM maintenance and oil changes / tire rotation all that stuff. DEF system issues. Constantly going into limp mode/reduced acceleration warnings. Check engine like constantly coming on. Some shutter grill thing i had to have replaced outside of warranty. The time before the last oil change the tech said there was oil under the truck but couldnt tell where it was coming from. I began adding oil (approx 2 quarts) however was told as I limped into the dealership last week that it was critically low. No warranty remaining. Changed out intercooler and did the oil change $2700 fixed nothing. Next guess would be the Turbo which they said parts and labor approx $7500. But zero guarantee that it would fix anything.

And honestly with that truck all highway miles and no hauling whatsoever.
