Problems with FCA on a new truck warranty.

I have a lifetime warranty on my 08 300c, it has recently hit over 110k miles and every repair takes extra time to get approval. Now we are battling over excessive oil consumption. Anything over 1 quarts in 2000 has to be repaired. I took it in because it almost ran dry between oil changes. The dealership found several leaks and a bad oil pressure sensor code. FCA dragged their feet for a week before they denied any of that was an issue and they said there was no evidence of excessive oil consumption. So I got an oil change and said I would be back in 1000 miles. After 5 weeks and 800 miles the stuck sensor, failed and it was low a quart so I took it back. They fixed the sensor and replaced the pan and timing cover and valve cover gaskets and scratched my fender and broke my valve cover then had the nerve to ask me for another deductible, that was not happening I had already brought it in to fix this issue and paid a deductible. So they overfilled my engine with 0w20, I never run that thin, and I plan on going back after another 1000 miles to see how much oil is being used. Oh and my AC just broke, again. The dealership has been pretty good to me, except for the scratch. They paid the extra deductible, FCA would not budge and neither would I, so I think they just ate it. $100.


How do you get a lifetime warranty on an 08?
