The redesigned Sonata stands out among staid midsized sedans with its sleek profile. Even so, it trails the category’s perennial leaders—the Honda Accord, Subaru Legacy, and Toyota Camry—in CR’s road-test results. The Sonata is fairly roomy, with good driver visibility in spite of its rakish lines.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for about 329,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2020 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

What Owners Say

Engine rebuild or replacement

"Two days after I purchased the Sonata, as I was driving, the engine died, the car stopped, and would not restart. The car had 120 miles on it. Hyundai eventually determined it was a factory flaw (something to do with the cam shaft) and replaced the engine entirely. It was in the shop for four weeks. I had to push considerably with the US Hyundai headquarters and the dealer to be given the choice to just get a new car or to be recompensed for not getting to drive my new car for a month. Eventually Hyundai did agree to buy back the car for the full purchase price, or to kee the car and receive $4500 for my trouble. I kept the car and took the $4500."
