That 02 Kia is due for a timing belt right now, service interval for those is 60,000 miles.
Some cars have non-interference engines, meaning if the timing belt breaks you tow it in and have it replaced. Most Toyotas are like this.
Some cars are interference engines, if the belt breaks while driving you can damage the cylinder head, turns your $600 belt job into a $1800 head rebuild. Most Hondas are like this.
Every Kia Rio that I’ve seen break a belt while driving has resulted in engine destruction. Broken pistons, head damaged beyond repair. Chevy Aveos are like this too.
That aside, I don’t think Kias are bad cars. They are just not at all forgiving when it comes to maintenance. If you don’t replace the timing belt at 60K, it will break at 70K. Follow the maintenance schedule to the letter and keep all the fluids clean and full and drive it like the economy car that it is and they can be quite reliable cars.
