Warranty:
When it comes to protecting you and your vehicle, Hyundai pulled out all the stops. When compared to the 2020 Hyundai Sonata warranty, the 2020 Kia Optima can’t compare. Both warranties provide 5 year/60,000 mile limited basic warranties and 10 year/100,000 mile powertrain warranties but Hyundai outshines Kia with their 24/7 roadside assistance and anti-perforation warranty. The 2020 Hyundai Sonata warranty offers a 7 year/unlimited mile anti-perforation warranty and a 5 year/unlimited mile 24/7 roadside assistance program, while the 2020 Kia only offers a 5 year/100,000 mile anti-perforation warranty and a 5 year/60,000 mile roadside assistance program. Hyundai has also kicked it up a notch by providing complimentary maintenance for 3 years or 36,000 miles (whichever comes first) which Kia doesn’t offer at all.

Overall when it comes to fuel economy, performance, interior space, safety and warranties the 2020 Kia simply can’t compare to the 2020 Hyundai Sonata.
