I am the second owner of the car bought Oct of 2023. Car was burning through oil thought I needed an oil change and did this ( should not have needed it since it was done just before buying) and days later check engine light came on Hyundai said it was a knock sensor. They replaced it and exactly a month later check engine light came on again. Now they are saying engine is shot and will cost $20,000 to fix. Car had great maintenance records. These cars are not safe as the engine can blow or the car will come to a stop at any minute while driving down the road putting not only the vehicle occupants in danger but also anyone driving near them. First started December of 2023 and sencond problems was January of 2024. I will be uploading all the files I have related to all the times it has been looked over.

Engine oil consumption test at 1,000 miles after oil change. All oil gone. Happened for two oil changes. Engine light came on. I paid 5k in repairs for catalytic converter/manifold. Dealer contacted Hyundai to do combustion cleaning they said no. Dealer told me keep checking oil as my engine will seize on me. I'm terrified and this is dangerous to me and others. Hyundai knows of this oil engine problem still no recall.

This vehicle was purchased used in 2020. In August 2022, during a daily commute, the engine began to sputter, lose power, and ultimately shut off at a traffic light. Fortunately, this happened on surface roads where speeds are low and traffic lights are frequent. The car was safely restarted and brought to a nearby service center. The car was subsequently towed to a Hyundai dealership 1.5 hours away because the local dealership was overwhelmed with vehicles and had a five-month wait for appointments. Despite having less than 67,000 miles, the engine had been experiencing excessive oil consumption for over a year. According to the Hyundai service center, the engine needs replacement. The Hyundai service center in Killeen Texas indicated that three of the four cylinders are below their piston compression requirements. Public sentiment on the excessive oil consumption problem can be found in the numerous comments on this website: [Top Class Actions - Hyundai Class Action Alleges Excessive Oil Consumption] [XXX] ]. I reached out to the Chief Customer Officer at Hyundai Motor America to determine whether they would stand behind their product and provide compensation for this obvious defect. However, Hyundai refused to offer any compensation, stating the car was outside its 5-year, 60,000-mile warranty. The excessive oil consumption leading to engine failure is a potentially dangerous issue for these vehicles.

After oil change, i noticed oil spots on driveway. Took it back to place that did oil change. They told me I had a crack in my oil pan and that it was caused by some sort of engine defect that causes engine oil pressure fluctuations that eventually cause the pan to crack. I believe NHTSA has opened an investigation into this issue.

am writing you today in frustration with my treatment at both your dealership Hyundai Streetsboro and Hyundai of Bedford. When I first purchased my vehicle I expressed concern regarding the hesitation while accelerating and the emense amount of oil this vehicle burns. When I scheduled all my services I expressed the same concern only to be told that it's normal rate or oil consumption. I am extremely nervous when merging into traffic because I never know when the car may decide to not accelerate. I have tired on numerous occasions to get this issue checked by two separate dealership but both dismissed my concerns. I have emails and expressed concerns when using the dealership online service request forms. In summary the vehicle hesitates when trying to accelerate, especially merging into traffic. The vehicle also burns oil at an unreasonable rate as a result of a faulty engine.

Driving down a 4 lane highway my car refused to accelerate and started shaking vigorously. My vehicles check engine light began to flask on and off. Had to pull off the high way and take the back roads the rest of the way home in fear that it would stop in the middle of the street. As we drove home, every time we would slow down or had to come to a stop the car would continue to shake and rattle with the check engine going and and off the rest of the way home. Took this to the dealership and they stated that I have a burnt exhaust valve on cylinder #2 along with needing a new catalytic converter and told me I should just replace the entire engine. I have 67k miles on a 2017 hyundai Santa Fe.

Upon checking my oil, I realized it was consuming at a high rate. The car dealership said there was no problem with the car. A couple months later I took it to a Hyundai dealership and they said the same thing. Now I am 6 months into owning this vehicle. Same issue. I am putting 4 qt of oil in my vehicle a month. Google said there was recalls on my year for a bad crankshaft that was causing this issue. I called the Hyundai dealership again. They said there is no recall for my vin number. I am having the same problem described. Oil consumption at a high rate. Which is wearing down the bearings in the crankshaft, causing the over consumption. I was told because my SUV wasn't on the recall list, there was nothing they could do until it is put on the list.
