I purchased my Tucson SE in January 2020 from Enterprise car sales in Las Vegas, Nevada. It had 17,600 miles and was assembled on January 4, 2019. It now has about 20,700. Shortly after the purchase I checked the oil level and I noticed it was above the Full mark (and also unusually dark red). At first I thought nothing of it and assumed it was filled too high, but after changing the oil myself in November 2020, the level has creeped up again to a little above the full mark. Since the change, I've accumulated about 600 miles of almost all city driving. It also smells a bit like gasoline, but I've had several vehicles where the dipstick smelled like fuel.
After doing more research on this issue, it's becoming evident this engine, the Direct Injected version of Hyundai's 2.0L Nu, has experienced a problem like this before, but mostly on 2011-2013 model years and in Elantras, which I think use the 1.8L but the engine is very similar to the 2.0L. I used Hyundai's recommended Quaker State 5W-30 full synthetic and a Fram ToughGuard oil filter. With Enterprise vehicles, all maintenance is performed at the dealer, so my Tucson has had its oil changes done at the dealer (and unfortunately followed Hyundai's 7,500 mile interval, which I think is WAY too long).
I've experienced no other issues with the engine or the car and it's been very reliable, but I'm moderately concerned about the fuel diluting with the oil. The redesigned Honda CR-V has this exact issue and Honda eventually issued a recall, but so far I've heard nothing from Hyundai. Am I the only person who's noticed this? If not, please share your experience on this website.
As of now, I don't plan on doing anything, as there's not really anything that can be done. I do make relatively short trips 3-4 times a week, which I've read can contribute to this problem. I'll try driving for longer and faster periods of time and keep an eye on the level. The engine sounds runs perfect, but this dilution is not "normal" and should be looked into, as lack of proper lubrication can result in engine failure. If the problem gets significantly worse, I'll file a complaint with NHTSA, but I hope I never have to. For now I'll watch it very closely.
