 This is the first vehicle I have ever bought myself. When I first got it, it ran great! I was getting 34 mpg in the city, and about 39 highway. I have had this vehicle for 3 years, and within the last two year I have started having major issues. first off, you cannot get part for this vehicle from an auto parts store. you have to get it from a licensed KIA dealership. two, the engine shakes sometimes. when I am sitting at a red light it starts to shake like it is going to explode. and since the engine started to shake and the way the car is designed, the AC compressor is nicely placed right in front of the radiator overflow. so when the motor shook it burned a hole into the overflow, melting it and making me lose antifreeze and making the radiator cap break. in this specific car, you have to replace the whole radiator to replace the overflow. three, over heating issues and knocking from the motor. I take very good car of this car, it is in for maintenance every 3 months and have the paper work to prove it. but every single summer it over heats no matter how careful I am. four, going up hill... you can step on the gas as hard as you want and it will not go any faster. five, the van does not turn on all the time. I have had the Carfax pulled and there are no records of issues from the previous own. I hope this helps. but I will never buy a KIA again. I paid 9k for this car and I have put over 15k in fixing it. this car isn't worth the stress.
