Mine had the oil changed this past Saturday; Monday night, the leak started. The dealer confirmed it's the rear main seal but the part is on back order till May. That is a uge problem for me; vehicles I've owned in the past 10 years are 2008 Chrysler 300, 2017 Ram 1500, and the 2018 Jeep Wrangler. Kind of funny having the worst issues with the newer one.What sucks some of you have 2019's. Kinda of shuts up the whole don't buy first year jeep argument. Bottom line is these things happen no matter what model year.
On a separate note. I wonder if some of you are noticing this after an oil change. Did you all confirm that the dealer didn't overfill as what seems to be happening with a lot of people here? Some dealers are putting in the JK amount of oil and the JL takes 1qt less.
