On my way home, heard a rattling noise coming from my vehicle. Pulled over to see if anything might has gotten stuck underneath and everything looked good. Drove it home and took it to a mechanic next day. Was told by my mechanic that the bottom of the engine is knocking, it had been burning oil internally and engine needs to be replaced. Contacted Hyundai and they stated that warranty had been extended to 120,000 miles and they only want to cover a small percentage to replace the engine.
I am having an issue with the panoramic sunroof. I has loud rattle sound as hell. I have contacted several times before my warranty expires but they refused to fix it.
