2018 Hyundai Sonata - ENGINE Failure Complaint (#b0b0f3)

2018 Hyundai Sonata

  • Date of Incident: Jan-12, 2024
  • Date complaint filed: Mar-26, 2024
  • Failed components: ENGINE

The engine of my 2018 Hyundai Sonata has been losing oil at a significant rate. By the time I take my car in for a regular oil change the oil is either completely out or nearly out. I contacted Hyundai regarding an oil consumption test which is what was recommended to me by Hyundai corporate when I called to report the problem. Hyundai has completed the oil consumption test and although they stated that it is consuming oil at a higher than normal rate, it still meets their “standard” and the recommendation that they have was to fill up my oil every time I put gas in my car which is an unreasonable expectation . The safety risk is significant. Although Hyundai recognizes this is an issue, they have said that there is nothing they can do. For a vehicle that has only 79,000 miles on it, there is no indication of where the oil is leaking to. During my last oil change, valvoline stated that this is a known issue and that the oil leaks into the engine of the vehicle. Hyundai inspected the vehicle and again stated that although it is burning oil off at a higher than normal rate, their standards state that it is not burning off enough to warrant an engine repair. The oil warning light did appear just before my last oil change which was approximately January 2024. When the light came on, I immediately scheduled an oil change and that is when I was first made aware that this was a known issue with certain Hyundai models
