“While I was driving on the interstate, I heard and abnormal about of noise coming from the engine bay as well as a scratch while I was driving. This happened on march 26, 2021 at 10pm. On march 29, 2022 I took it to the dealer ship and I was notified that my engine cover came off and was the cause of the noise. There's damage to my driver side fender, rubbing to the wheel/tire and my fog light housing is hanging.”

“I was driving down the highway when I heard a loud explosion like a gunshot that caused me to slow down and almost getting into an accident. It was scary; I came to a stop and realized that my sunroof had exploded. There is a large hole in my sunroof bigger than a watermelon with glass particles everywhere.”

“While driving home from work, traveling on a state route at 55 mph, the cover under the engine just snapped off on the passenger side of the vehicle. It just started making a loud noise like I had blown a tire! I pulled over and noticed it was hanging down on the road. I had not hit anything, the bracket had it fully broken, it could have caused me to wreck or put any other drivers at risk for an accident. This isn’t the only Kia K5 I’ve seen with the engine dust cover hanging beneath the vehicle.”

“My car just stopped working, it was towed to a local Lokey Nissan in Clearwater FL where it was purchased. Since it was a defect Lokey Nissan sent it to Lokey KIA in Clearwater FL. Lokey KIA stated the gas can had expanded and also caused damage to the frame and the cost to repair was more than the value of the car so they sent it up to Corporate for further instruction. This was 6 weeks ago. Nobody will return my calls, KIA still has the vehicle and I am getting nowhere here and am without a car. Please help I don't know what else to do!!!!!!!!!!”

“The Wheels Guards fell off mid drive, another part that fell off was the underbody cover that is made out of cardboard. I know many Kia K5 owners who have had this problem. It fell off due to rain. Since it is made out of a cardboard like material, the rain makes it fall off while driving.”
