Dead battery because headlights would not automatically turn off after parking in garage. WHY..I got seat belt stuck in door after closing door the car body was bent misaligning the door button that turns off lights when door is shut. Repaired by KIA Dealership...HOW..placed metal washer (as spacer) to behind door button to re-align. Thus when door is closed the headlights now turn off and the battery does not get drained.

Heated/Cooled driver seat had stopped working previously. A switch and a module were replaced and BCM flash done during previous attempts. Since it's now intermittent (it's stopped working again at times), they say they cannot work on it. UPDATE: around 3,500 miles so far. Heated/Cooled driver seat worked (once), mostly not working. Dealer & KIA corporate have said they won't fix it if it isn't completely dead. So I wait until it dies permanently. Might never get fixed!

They installed the wiring harness. The system works (it was working prior to installing the harness after they cleaned the contacts), so we'll keep an eye on it if it's finally a permanent solution.
