NHTSA Complaint #11559379 — 2018 HYUNDAI SONATA

Purchased this vehicle with about 64K miles. Vehicle, as per CarFax report, has been meticulously maintained. Upon delivery, we changed the oil and filter with full-synthetic Amsoil. We ensured oil levels were appropriate prior to returning to service. No more than 1,000 miles later, roughly incurred in about a month, we checked oil levels again. This time, it required about 1.25 quarts to return it to the appropriate level .We did research and apparently, there is a class-action lawsuit filed by owners of Hyundai vehicles with this specific engine, the Theta II 2.4L 4-cylinder engine. Here's an article making reference to apparently your organization already looking into these complaints. [XXX] Could you please advise if the NHTSA will take the necessary steps to request Hyundai to issue a recall? I have found multiple articles where Hyundai is rejecting to take any action on their own, in most cases, advising their customers that such level of oil consumption is 'normal'. That clearly contradicts their own owner's manual guidelines. I own a 2001 Chevrolet Suburban 1500LT with 302K miles and the vehicle will go nearly 5K miles between oil changes while requiring no more than 1/2 quart of oil to keep it at the appropriate levels. I also own a 2019 Honda Accord 2.0T that normally requires oil changes every 10K miles and it seldom requires more than 1/8 of a quart to keep at the appropriate oil levels. There is definitely something definitely wrong with this engine type and requires governmental involvement to hold the manufacturer to provide adequate remediation. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
