NHTSA Complaint #11436337 — 2017 HYUNDAI SONATA

Engine oil found to be low at multiple oil changes. So started checking levels 1000 miles after oil change and found oil to be low already at that point. The last check, only 1300 miles after oil change, found vehicle to be down 1.5 quarts. Available for inspection upon request. Because we are checking and replacing the missing oil at the early timeframes of 1000 miles instead of at 7500 miles, no one is in immediate danger (beyond my bank account). The service center has been monitoring the issue for some time. They checked seals, gaskets, and replaced them to be sure they were not the issue. The oil levels still decrease. Upon speaking to a Hyundai rep, he (the manufacturer) claims there is no issue but I should get a diagnostic check up at dealer. I am scheduling one this week. Issues with the local dealer is they charge too much, suggest repairs that are not necessary, and have extended service wait times of at least 3 hours even though I have an appointment. There have been no warning lamps, messages, or actual failures. I am trying to prevent reaching that stage. I do know that my engine is the same one they recalled from earlier models. Those engines were having high oil consumption issues which help lead to more serious safety issues with time. I am wondering how the same engine, with apparently the same issues, was allowed to continue to be used.
