 This is my third sonata, my first hybrid.  The gas mileage on average is 19 to 22, the electronics reset randomly. The cruise control has a mind of its own and when set at 45 mph I have had it accelerate on its own to above 70 mph. I couldn't be more dissatisfied. I have had zero response from Hyundai. They just transfer me to the dealership which hasn't produced any results.
