I don't know of any Hyundai Corp extended warranties.

I purchased a brand new 2011 Sonata in May of 2010. Drove it for 5 years/70,000 miles. After 5 recalls, a thermostat failure, more interior rattles than I could count, an engine that was using 1qt of oil every 800 miles, door latches that didn't want to latch below 30 degrees F, a serpentine belt that squealed when driving through a puddle followed by a battery warning light [normal according to the dealer], and an automatic transmission that would occasionally shift so hard it would give you whiplash, I was not sad to trade the Sonata.
The Hyundai dealer really wanted me to get another Sonata, and I did test drive a 2015 2.0T Sport just to give them a chance. The dealer actually said to me "we know your 2011 Sonata was not the most reliable car for you, but we believe the 2015 will be a better car for you in every way." Despite offering $5,000 off it wasn't enough to get me to stay with Hyundai.
My current Chevy, while not perfect, has been much easier to live with in the first 3 years/37,500 miles than the Hyundai was at the same point in time.
The Sonata always seemed like it was only 95% fully engineered. There were always little things about it that seemed incomplete or not fully thought out.
