Consumer Description

I have had issues with oil consumption in this vehicle for about 4 years. I started getting a "Knock Sensor" code. I replaced the knock sensor and still had problems. Hyundai had a recall and they reprogrammed my computer board. A year later I was having the same issues. My car started stalling out. Took back to the dealership they said my engine had sludge and now they're saying that there is a hole in my engine. Hyundai is saying that I don't qualify for assistance.
