Kia/Hyundai had hundreds of thousands of vehicles for recalls. many instances of engines catching on fire, engines seizing up, engines losing power, metal shavings in the engine, crankshaft wear, etc.
you're close to the "engine failure" of 80-100k miles. mine has regular maintenance, had an oil catch can, expensive racing quality spark plugs, full synthetic oil every 5K miles, and drove prefectly fine, until 2weeks ago at around 87k miles then suddenly without warning engine loses power on the highway. luckily it didn't seize. my regular autoshop was a few miles away. they ran the ODB code and said it was the 3rd Kia that week that threw a manufacturer specific engine replacement code. i was able to get to the dealership a few miles away. still waiting on the replacement engine to ship from S.Korea. Kia is paying for some of the rental car, but still costing me $30/day going on 2 weeks now.
this is my 1st and will be my last Kia/Hyundai. my co-worker had a Hyundai with around 80K miles, his mechanic friend that works at a Hyundai dealership warned him he was getting close to the engine failure mileage. he traded it in for a Toyota.
