1 year and very happy w/my Sonata
First Hyundai purchased after my beloved Ford Fusion Hybrid washed away in a flash flood. Since Ford decided to stop selling them, we moved on, bypassed Honda due to high cost add-ons, and found Hyundai. Wonderful dealership, good service department. The Sonata gets 40-50mph and runs great! I love it, the kids love it. Bought an Elantra 6 months later when another car bit the dust.The 10-yr warranty is also a nice feature among the competition.
