My 2020 RAM 1500 has been having issues since I got it 1 year ago. Last winter from a cold start I would get a very rough idle (seemed to be missing), engine light came on, brought it in and they fixed a vacuum leak. Issue continued intermittently until weather got warm. Just happened again last week, engine light came on, brought it in, it had a multiple misfire code. They checked plugs and coils, everything was fine. Found out it was 4 qts low on oil! Oil starvation was causing the misfires. I asked where is the truck burning or consuming oil since no leaks were evident. They told me since I was 3K miles overdue on oil change (full synthetic, still 15% oil life left according to my truck) the truck used 4 qts. Sounds like total bs to me. So I brought it home and am waiting for the problem to start again, and will be checking the oil. 4 qts is a lot of oil to just "disappear". Any ideas? Or similar issues? I don't think there is any way a new engine with 13K miles should consume that much oil because it was "overdue" for an oil change.
