I have a 2017 Santa Fe Sport with 88,000 miles. I bought it pre-owned, and the warranty expired just days before my check engine light came on. I took it to a shop, and they replaced the O2 sensor. The light came back on two weeks later, so the shop replaced it again under warranty. When the light returned a few weeks later, the shop owner suggested it might be an electrical issue and referred me to an electrical specialist.
The electrical specialist found that my car had no oil, even though I’ve been keeping up with regular oil maintenance. He mentioned that Hyundais are known for burning oil, did an oil change, and advised me to contact Hyundai corporate. I took the car to the dealership and opened a claim. Hyundai’s corporate inspector came out, and they replaced the catalytic converter. However, the check engine light remained on.
Now, the dealership is saying that an oil valve (or something similar) is broken, causing oil to leak into the wiring harness, ECM, O2 sensors, and other parts. This is why codes are being thrown and parts are failing.
Does this sound like an issue that Hyundai corporate should look into and possibly cover under the engine warranty? The dealership says fixing everything will cost $5,000.
Should I push Hyundai corporate to cover these repairs?
