Maw_76 my good sir, the service experience is exactly why I will never buy another Kia or Hyundai again. I love my K900 but the service is always a three ringed circus. Every time I have to do any service its hours of my time wasted. I started changing my own oil since it took 4 hours with drive time. I hope the new battery will solve all your issues and i would highly recommend getting a battery maintainer since the battery issue has been going on since the 2015 model year.
