I have 2012 3.8 with 88k miles. Same engine as 2015. Bought car new and it has never been in shop.
I got P0133 code last month. Cleared it and it went away for a month. Now I'm getting P0133 and P0153 codes. Cleared both yesterday and they went away.
Engine has had a very subtle stumble at idle for a while. The engine has blown black exhaust smoke since I bought it new when dropping the hammer passing but oil usage is unmeasurable even after 4k miles.
I won't bring it to dealer until the codes are persistent or more codes appear.
My Dealer wants $250 just to do a diagnostic check. I'm not dumping major money into a car this old.
