I purchased my Kia Rio new in 2004 and treated it well - always got oil changes on time, replaced the timing belt at 90,000 miles (I was told to do it by 100k).
Within 3 years of purchase the brake proportioning valve went bad.
W/in 2 years the rear tires were going bald far faster than they should have - turns out I was sold a new car with a bent rear axle.
Past 2 years (100-120k): intermittent electrical problem that we finally realized (after replacing the spark plugs/wires 2x) was a cracked engine coil.
Last week (139k): fourth cylinder blew.
Got relatively good gas mileage (about 28-30 mpg), but my partner's 03 Toyota Matrix did just as well with far more pep.
The interior is poorly designed, but I could live with that.
I expect that if I pay for a new car with a 100k mile warranty, it will run reliably for at least 150k miles.
I will never buy another Kia again.
