What 2024 Kia K5 owners say
Engine & cooling
I was driving on the expressway and the engine made a noise and I lost power. I was in the left lane of the expressway. I did not have any warning lights or signs or symptoms prior to this incident. No oil ever leaked prior to this incident. When it occurred, oil was pouring out of the engine all over the ground. The engine was smoking. And a warning message came across the entertainment screen that said, "A possible condition with your engine control system has been detected, recommend service soon" I never received any notification of any oil pressure loss, oil loss, warning lights, nothing. My car has been at the dealership for over 60 days, and KIA is refusing to cover the engine under warranty, blaming an oil change place that did an oil change over a month prior to this incident, and I drive 100 to 200 miles per day for work, so this would have occurred sooner. …

My car has noticeable defects that affect the driving experience and can be dangerous. When coming to a stop the engine turns off as if it was deactivating one or more of my cylinders. While that happens it stalls the car. My adaptive cruise control doesn't work as intended since it came damaged from the manufacturer, while driving with the adaptive cruise control on the vehicle requires more input to maneuver.
