Hello and TIA! I have a 2018 Wrangler Unlimited Sahara w/ the 3.6l, auto trans, at 88k miles, mostly highway. This Jeep has been babied and never abused. It started with a hollow knocking noise from the front. I initially suspected it was the cam chain tensioner/guides (had similar sound from a Charger I owned and was the tensioner and guides). Two days later, the knocking got much worse and louder. Took it to the dealer, they initially thought cam, lifter, tensioner as well. They wanted $900 to open it up but stopped as the shop foreman said it wasn't worth it, it now has upper and lower knocking. Very rough running, now burning oil (oil change 350 miles ago and now black), oil filter shredded, flashing cel, and of course now the cat is fouled and needs replaced. Pulled the codes: P0420, P0300, P0301, P0303, V0109, and P025A. Last two don't make sense as it still runs. Pulled #1 and #3 spark plug, both oil fouled but not damaged. So, long story short, has anyone had an engine failure like this? FCA touts this engine very well, but to have a catastrophic failure like this seems unreasonable. BTW, no warranty left...
Just looking for some opinions about cause (I know wide open subject)? I'm going to call the regional FCA rep for starters on Monday, but would like some more info before I do and what to tell them and ask for, other than a new engine.
Thanks for your time!
