I am sitting on 90k miles and I believe the first major maintenance is at 100k. I have a 150k extended warranty that is not from KIA so my fear is if I don't check the box on the scheduled maintenance, I will have an issue if I need a repair under warranty. My backup camera doesn't work intermittently but of course when I get ready to take it in, it works just fine. I also have air coming in my drivers side window when it is rolled all the way up. I guess my October 2013 purchase of my 2014 Cadenza is starting to have some nagging issues.
