Just a FYI. 2021 Seltos. One year old (almost to the day) and 18,227 miles. I went to start it yesterday morning and all I heard was a bunch of relays clicking. I put a charger on for 40 minutes and it started. I drove it to my dealer and the diagnosis was the battery. Charging system OK. They replace the battery under warrantee (no charge). I noticed that the new battery was a tad different. Still a Kia brand battery but it had a large label on it that stated 36 months, 100% FREE replacement. Pretty cool. Since I live in a hot climate, I appreciate the warrantee. Interesting note: My dealer will put in a 3 year Kia battery under warrantee but will use an Interstate battery for out of warrantee, paid service.
