I have a 2018 Tucson with a 2.0 with 120,000 on it. No codes or dash lights on. Engine burns oil. Coolant is also low with no signs of leaking underneath. When driving it loses power going up hills. There is blow back coming from oil fill hole. I believe there is a TSB on it and have heard that Hyundai is replacing some motors. Looking to see if anyone else is having similar issues. What's the best way to approach the dealer that would give me the best chance at them covering the new motor?
