 I have now owned my Sonata Hybrid for just over six months.Like most of the early adopters of this automobile I had the check engine light issues until Hyundai figured out what was happening.Kudos to Hyundai for working diligently to solve the issue and provide us a $50 gift card as compensation for our trouble.Meanwhile, I've enjoyed a mid-sized luxury car ride with penny pinching average fuel economy of 38 mpg over 16,238 miles!Within the first few miles of driving I sense a little hesitation in the transmission but after a few minutes it's fine. I get lots of questions about my Sonata Hybrid and many compliments on the styling.I would not hesitate to purchase another Hyundai!
