I have bought 2 kia's from this dealer, the first being one year old and the second one being brand new around July 2017. around January of 2018 around 25 degrees my car would not put out heat, so I stopped by the fishers location (which I've been told was owned by the same group), the temperature was very cold and my car would not heat up, I showed the service representative. when I tried to schedule the service I was told that they would not provide me with w loaner even though I just bought the car less then a year ago and the sign in the lobby said that they did and the work would be warranty work. so I had to drive the car like that for three weeks until I could get it set up to have a ride to work. they replaced my thermostat and gave me my car back. there wore not any more days cold enough till the following season. I then had a problem again, this time I took it back to the dealer I bought it from around thanksgiving 2019 and left it for a couple of weeks, they replaced the thermostat again. I asked them to keep it a couple more days and test it again when it was cold, they did and called me back to tell me they were going to do a reprogram on the computer, a couple of days later they called me and said it was done. After picking it up I did seem to work better but I lost 9 mpg, went from 41 mpg to 32 mpg hwy. When I call the dealer they told me that the optima only gets around 32 mpg even though I have been driving this car almost 2 years now and had already put 30,000 miles on it due to a lot of traveling, so basically I got called a liar.
Around January of 2020 we noticed that now around 15 degrees we did not get heat, I took it back again, they had it for a couple of days and called me and said that there was nothing wrong that it was normal for this car to do this. so I took it to a totally different dealer about an hour to an hour and a half drive and dropped it off on Friday the end of February, on Saturday I called and they had not looked at it and did not plan to until some time next week. this was my final straw, bought a brand new car and could not get it fixed, including the in November of 2019 I contacted Kia motors and heard nothing by by February, so on president's day I traded it off. I shortly after finally heard from Kia motors and started receiving calls about service, I have called, tested stop and emailed stop to get the calls to stop and they still don't stop. I would not recommend to anyone.
