New gen dodge dart anyone having issues?

She came over today. Dont have a code reader so couldn't pull any codes. I know a lot of people that had similar issues stated that they took it to the dealer and the dealer said the engine oil level was low. So sure enough checked the oil and it was about only 1/4" up the stick. Went and got penzoil platinum 0w20 which is what it calls for and what dodge sells, a wix filter and changed the oil. My dad changed the oil 3,967 miles ago with the same 0w20 penzoil platinum and we measured what came out of the oil pan and what came out of the oil filter. We only got 2.5 qts of oil out and it calls for 5.5 qts full. So 3 qts of oil used in almost 4,000 miles? No leaks under the car anywhere and only has 34,967 miles on it. It did it again today before she came over and happened in the same spot on the same hill. We'll see if it does it again with the oil level full
