“While driving on an interstate on-ramp, I heard a loud bang from under my hood. I exited to the shoulder and as soon as I stopped, I heard a second, larger bang from the same area. Within a few seconds, flames started coming out of the engine compartment and began to fill the cabin of my vehicle from the area of the air vents and all through the dash. Within five minutes, the vehicle was fully engulfed in flames. I had no problems with the vehicle up to this point and the maintenance was up to date.”

NHTSA complaint #11690228, filed 2025-09“This pre-owned vehicle lost power at an intersection with my wife and child in the vehicle. Both of them were fearful and in tears.

Although the mechanic told me that he knew there is a problem with the vehicle, Kia failed to diagnose or fix the problem(s), and could not assure me that the vehicle was safe to drive. Maxcare would not cover a rental car because no diagnosis was made. …”
