I have a 2016 renegade trailhawk with the 2.4L. I was wondering if anyone was having problems after the oil consumption recall to reflash the ecu. For mine after the reflashing the ecu I lost power, under acceleration it has noise from around the cam (kinda metal on metal), and vibrations in the cabin when idling in gear. Luckily I got the mopar extended warranty but it seems like they are at a loss. Now they are saying it's a blown head gasket it only has 71k miles and this is the 6 or 7th time I've taken it in for this issue and it seems like they just throwing parts at it. They did 2 new coils (cylenders 2 & 3), new engine moints, new plugs (not champion), reflashed the ecu (every time it went in) and the engine damper. Really just wondering if someone had the same issues and how it was fixed.

That's nice to offer but I have been dealing with the chrysler care but all your team just said to take it back to the dealership that I pay $100 under warranty every time to fix the issue just to get it back with the same issue. I did take it to a diffrent dealership and now they are saying it's a bad head (valve train), head gasket, thermostat, thermostat housing, and ac compressor. This "Jeep" only has 71k miles and my 07 wrangler didn't have this many problems with over 170k miles. To be dealing with this problem for 2 years and after the 4th time getting it back still with the problems that's when I called to get help to get the poorly designed FCA POS to run right and your team hasn't been helpful. It's been stick at the dealer and I'm with out a car but all your team says is if I get a rental I MIGHT get a partial reimbursement it's a joke. I'll stop my rant now also this is the last Chrysler/FCA/Stellantis product I will buy due to the poor customer service, and not caring about the quality.

So I got the Jeep back. Cylender 2 valve was bad, the ac compressor was replaced (its freezing where I am 0C), oil pan that been "replaced" one before and resealed 2 times before, and the thermostat. It's funnily running right after fight with FCA and their customer support.

I did do a bit of research and the tiger shark engines the block was designed by Hyundai and is the same design as the Theta 2 that are know to be unreliable. The head and the manifolds are designed by FCA tho.

The Theta 2 had other issues mostly related to manufacturing processes. A lot of engines are going to low tension piston rings and shorter pistons, all in an attempt to reduce friction and improve mileage. That often results in poor ring seal (causing oil consumption) and/or piston slap.
