I bought my 2018 Hyundai Santa Fe Sport from Toyota of Scranton as a certified pre-owned vehicle. I was told by the sales representative, Doug, that the car had been “checked and serviced, everything down to a full tank of gas”. In March, my oil light quickly flashed. When I checked it there was low oil, so I did an oil change. In June the oil light quickly flashed again. I informed Toyota of Scranton and they recommended an oil change and changing the drain plug. They reimbursed me after I did so because I had bought the car so recently so I “likely bought it that way”. However, the issues continued and I had it looked at by Kost Tire & Auto Service to rule out a leak. On November 6, 2024 I brought it to Toyota so they could diagnose the issue, as I am still in the mileage window for my warranty. I picked up November 8, 2024 to begin a 1,000 mile oil consumption test. I brought the car back November 27, 2024 and it was established that the car was “excessively burning oil”. -- The engine has failed. -- The dealer confirmed the issue. -- The warranty company says they do not consider this issue a "mechanical failure" and will not cover the damage. -- Toyota tore down the engine and the warranty company inspected it. The car is still sitting at Toyota torn down.

In May 2024, the vehicle's oil light came on while slightly turning the wheel or braking. When taken to a dealership, they stated that the car only had one quart of oil remaining, which was 4,000 miles after my last oil change and not due for another 1,000 miles. They stated there was excessive oil consumption and recommended the vehicle be taken to Hyundai dealer. I took the vehicle to Hyundai dealer in August 2024 because the car was making a rattling sound when accelerating from 0-40mph along with the car jerking between 30-40mph if accelerating except when only applying light pressure to the accelerator. Hyundai dealer stated there was no oil remaining in the vehicle, which was why the vehicle was shaking and rattling when accelerating. They began a claim process with Hyundai as the vehicle was under 100K warranty. After two consumption tests, it was deemed the vehicle was not consuming oil as previously thought. After the last consumption test in October 2024, the oil light began to come back on with me braking the vehicle. Hyundai dealer stated there was nothing further they could do to assist and stated I'd need to reach out to Hyundai customer care to file a report. I did this 10/18/24, and in December, Hyundai customer care told me to take the vehicle back to Hyundai dealer. Hyundai said at that time that now there was an oil leak from the oil pressure sensor, which allowed oil to pass through the entire main wiring of the engine until it reached the PCM. They said I need to replace the PCM, oil pressure switch, and engine control harness for $7,000, not covered by the warranty. Parts are also on backorder for over a year. My car's oil light continues to come on, and now the engine light is coming on while my car shakes when I reach 45mph or greater. It is deemed no longer safe to drive the vehicle, especially with my children in the car. When I checked the dipstick, it was completely out of oil, which was 1500 miles after they performed oil change.

In 2024, I initially suspected that my car was being improperly serviced at local Jiffy Lubes. Later, I thought it might be an oil leak, so I took it to the dealership. They informed me that there was an oil pan gasket leak and replaced it. However, when I returned the car a week later and said it wasn't fixed, they inspected it and claimed everything was fine. As months went by, I found myself consistently adding oil to the vehicle whenever the warning light came on. Whether I added 1 quart or 3 quarts at a time, the oil light would come on again about a week later, and I continued this cycle of adding oil. It was not until I found social media platforms/forums about a reoccurring problem with Hyundai vehicles burning oil. I have not talked to the dealership since so many people have stated in these forums that there is no solution because Hyundai denies there is a problem. I have 110k miles on the car and as long as there is no recall, I am forced to have the engine replaced at my cost. I am a retired, disabled veteran and cannot afford to have such expenses. There has to be a resolution to this problem with all of these peoples reports.

2018 Hyundai Santefe 2.4L engine burned oil at a high rate and due to this caused 4k oil changes obsolete. The car need an oil change every 2k miles and still would have high build up. Hyundai claimed engine failure was due to gaps in the oil changes them being done around 4.5k miles in the start. Many people have had engine failures with these car and they are still selling them with the defective engine to this date and not warning the buyers about the problems with these cars and are forcing the second hand buyers to pay $6-12k outta pocket to repair these cars after a year of owning them. I think Hyundai should be held accountable for these actions after they know these engines are defective and they still have them on their car lots for someone to stroll in and buy a $17k car with previous owners that will fail within the next year of ownership. Attached is maintence record for the vehicle.

Driving on highway, when accelerator failed to maintain, the car started to jerk. After blocking traffic behind me, I was able to pull car over on the side of the busy highway, with smoke coming from hood. This was well after dark, and it was towed to a local and dependable mechanic. He had told me the engine was cracked. I am in the process of finding out if I am eligible for the extended warranty, for I meet all requirements

I was on the highway and pressed the gas and the car started shaking. Wouldn’t go up in speed so I pulled off the highway and parked it. Checked the oil and it was almost empty even though I had an oil change about a month ago. Service center says it need a whole new engine at 108k miles. How is this possible? They say there were pieces of the valve in the fourth cylinder which also had lots of oil in it. I bought this car used and am only the second owner. Surely there is something Hyundai can do if they know about this issue.
