On 03/29/2019 was traveling to work. On interstate 53 southbound car went to limp mode. No power. Managed to get to dealership. They tried to repair my vehicle for 1 month after they told me that engine need to be replaced they managed to change wiring harness. After 1 month it was done. I took car back. 1 or 2 weeks later car went into limp mode again with same problem. Filed a claim with Kia and BBB to resolve it. As of right now they had in inspections on my vehicle as they stated from Kia California hq and from Korea hq with no luck to repair it. As manager told me they dont have any ideas how to fix it. Want Kia to buyback my vehicle and let me get away from this lease with reimbursement on payments because car not in my posession for 128 days and counting. They switched me 3 loners.

When I got in my car the check engine can on. I started driving my car to work, because I was not sure why this light came on because this was/is a new car. I have less than 19K miles on my car. As I attempted to get on the highway the car refused to speed up. The max that I could drive was 60 mph. I had to pull over to the side of the road because my car would not pick up speed. So I called the service department, who informed me that when I brought my car in for an oil change in January that they has place a saftey feature on my car to keep the engine from blowing up. According to the dealership, there is possibly something wrong with the engine, however, they are starting out by changing the wiring first. I can not explain how different this drives since the wires have been changed. It is the worst drive. The car is very loud it does not pick up speed when it should and it does not slow down as fast as it use to. Needless to say, I am having issues with this car and seemingly every time I take it in for repairs, the car gets worst. I will never ever buy a new/used Kia again.
