Hey, look who cracked the Top 100! Hyundai's economy marque has three vehicles in CarMD's upper echelons: The 2009 Sorento, Sportage and Optima. Unfortunately, Kia's repairs and repair costs were up, with the average price jumping 8% from $320 in 2012, to $346. The $313 oxygen sensor repairs that plague 9.25% are a problem, but that $1,120 catalytic converter replacement required in 7.28% of its vehicles really stings.
