1 Engine Oil/lubrication problem

Failure Date: 12/22/2022

We purchased a 2016 Hyundai Sonata in December 2020 for our son who is in college. In early August of 2022, my son noticed his oil light was coming on before it was time for an oil change. He had the vehicle topped off and maintained regular oil change and service schedule. While in for service at fitzgerald Hyundai in rockville, MD, August 2022, they replaced the spark plugs (4 cylinder tune-up) at 108,127 miles. The car continued to burn a lot of oil, so another appointment was scheduled at the dealership in rockville September, 2022 at 111,792 miles. An oil and filter change, complete 23 pt. Vehicle maintenance inspection was performed, and all fluids topped off. The vehicle continued to burn oil at an unacceptable rate well before an oil change was required. My son continued to get oil changes and top off before the standard mileage. Another appointment was scheduled with the same dealer in rockville, MD December 2022 at 118,989 miles requesting a diagnosis for the excessive oil consumption. After inspection, we were told an oil consumption test needed to be performed in order to determine why we are having this issue. We were also told that the spark plugs needed replacing again, less than 5 months from the previous replacement. Our service advisor said oil was probably shooting out onto the plugs. Hyundai denied the request to pay for the oil consumption test. The service advisor said she sees this a lot when I asked about excessive oil consumption on a vehicle with less than 120,000 miles. Also, they kept the car for almost 2 weeks. We are looking to rid ourselves of this piece of junk and purchase a vehicle by a reputable manufacturer. In the meantime, we are topping off and getting frequent oil changes. There definitely appears to be a defect with this year and model vehicle and Hyundai should acknowledge there is an issue and resolve it. I will never purchase another Hyundai and will spread the word to everyone I know, not to buy a Hyundai.
