I mean this kind of thing…
I mean this kind of thing happens all the time. It's not just Kia. I had a 4 year old 2020 Jeep Wrangler that was in the shop for 3 months because Jeep couldn't figure out what was wrong with it. It ended up just being the main battery needed to be a "Mopar" battery. You have to remember that they are mechanics not detectives. Just like doctors not all mechanics are created equally. 🤣
