What’s interestin is here in the USA only some states sell Hyundai EV’s.I understand that the 12v battery is a consumable item, but as your car is still under warranty shouldn’t a main dealer diagnose and fix whatever is causing the warnings, without any cost to you?
Light comes on.
I think it’s some module that’s nor working.
Bought new.I agree with the comments above. Please see a dealer. You have a major issue. It may a PCM or BCM (car computer) issue and needs dealer only attention. Have you read the OBD codes? Autozone typically will connect an OBD 2 scanner and read them for free. You can buy a scanner for under $20 and scan yourself. Post the codes here. I assume you bought this used? By chance, was it exposed to a flood? Crash history? How many miles? What year is it? The first 5 years, 60,000 miles is a bumper to bumper warranty that transfers to other Owners. Good luck, we have not seen any posts with issues like you have listed yet, so we all want to help.
