37000 mi A/C fixed on second attempt after waiting for a new compressor. They ordered a 2014 compressor since they've been having lock-up problems with the 11+12's. Once it was totally replaced, everything's ok.

35000 mi 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. 
3000 mi 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! 
5000 mi I've had ongoing issue with the heated/cooled seat. They replaced the switch a second time. Now they are ordered a new "wiring harness". Still awaiting that to come in for them to install. 
5300 mi 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.
