I'm curious how your situation worked out. I had a similar experience with my 2018 Hyundai Santa Fe Sport. I'm diligent about oil changes, every three months, full synthetic. However, the last oil change I got in April, my oil light flickered about a month later, so I took it back to the oil change place and they confirmed it had 1 quart of oil! They added almost 5 quarts..4.8, checked for leaks but couldn't find any. Two weeks later, checked it, had to add 2 more quarts. Checked it again 2 weeks, prior to my engine failing, and it was almost full. I didn't have any lights or warnings when the car broke down on the highway. It simply lost acceleration power and check engine light came on after we pulled over..when we checked the dipstick it was bone dry! Took it to my personal mechanic, he said the piston was broke due to oil sludge and I would need an engine replacement. So read about the issues with oil consumption and the lawsuits and the campaign about knock sensors and connecting rod bearings and thought could there be a connection? I contacted Hyundai corporate who confirmed my 8 digits of the VIN was identified as a possible engine failure (related to the knock sensor and connecting rod bearing.) They asked me to bring it to the dealership for full diagnostics. So had it towed, where they just told me the cylinder is broken and needs to be replaced. I said why did it break and they couldn't provide an answer but said it was declined the full engine replacement and not covered under warranty. Which I knew the warranty wouldn't cover it but I was told by corporate and the dealership prior to taking it in that it might be eligible for this campaign that started b/c they were being sued in a class action lawsuit. I asked if the engine had to be replaced and how much. The manager responded that it did not need to be replaced just the cylinder repair which is approx 3-4K. I just think this is complete crap and wonder how much more I'll have to shell out over this oil consumption issue with continuous problems. I've never in my life had oil in my car be completely bone dry or sludgy. I understand I don't have to have an engine replacement but who is to say this won't happen again. I'm so upset with Hyundai. I will NEVER buy another car from there. This was my first car to purchase from them and honestly loved it for the most part...until now. The engines are complete crap and it almost feels like a racket so consumers have to continue to take it to dealer for repair.
