NHTSA Complaint #11523116 — 2016 HYUNDAI SONATA

Car has less than 67,000 miles on it. Routine oil changes using 5W/20 Valvoline full synthetic oil. Approximately a year ago at less than 60,000 miles there was a noticeable difference in performance...especially when accelerating. Tried couple tanks of premium unleaded, but that did not help. I noticed significant oil usage...but no oil leaks. Within 1,000 miles of an oil change, I was having to add more oil. The oil usage is getting worse...now having to add a quart about every 600 miles. I have enjoyed this car very much, but I'm deeply concerned about the amount of oil it is using. I am the second owner so there's no warranty. After researching the issue, I see that many people are experiencing this exact same issue with their Hyundai. If Hyundai Motor Company wants to remain a viable company, they need to do the right thing and recall all these cars to be repaired.
