Kia Optima Engine Problems
Kia Sportage 2016: Turbo petrol engine in the future?

Kia told us that the recommended change timing is 120,000 km or five years, but it is also recommended that an inspection be done every 60,000 km. As you car is six years old I would suggest you have the belt changed.
