Dead Toad Battery
Just a good guess here is that your Kia is dead the same reason our 2020 Wrangler battery is sometimes dead upon arriving at our destination. Every time the brake comes on, all the instruments on the dash light up as if you are getting ready to start the engine. I had a charging line added to the pin connector and wired to the Wrangler's battery. I also had a RVi towed vehicle monitor installed. Now when the RV is running you can see that the toad battery is being charged. There were times before this install when very little braking occurred that the battery did not get drained. It is all about all the electronics on today's vehicles. Hope this info helps.
