Hi, I have a 2012 Santa Fe SE. After I drive the SUV for an extended period of time on the expressway(1-2 hours) and then its sits overnight I get a ton of smoke at startup in the morning. The smoke goes away after about 20 seconds. I don't see any excessive smoke during normal stop and go driving Im not sure if it is oil or fuel burning. Im thinking its oil because the more highway trips I take the more oil I loose. I talked to a Hyundai mechanic and he said it could need a tune up or it could be a dirty intake manifold where fuel is being absorbed into carbon deposits and burning off at startup. I think it could be valve stem seals. I personally have never seen that much smoke because the engine needs a tune up. The SUV runs great other than the smoke. Does anyone have any ideas what the problem could be or seen this issue with a Hyundai engine?
