My 2022 EV6 with 10,000…
My 2022 EV6 with 10,000 miles on the odometer never had any problems until the 12v battery suddenly died recently. Since it was under warranty, the dealer replaced it with a new battery. A week later the new battery died. I took it back to the dealer where it and 7 other EV6s were in the repair shop with the same problem. It took Kia a month to figure out the problem (they told me it was caused either by the Kia Access App or my local electrical utility's EV charging app constantly pinging the vehicle to check it's charge status). All that needed to be done was to change my password on the Kia Access App and unsync my vehicle from the utility's app. A week after I got my EV6 back from the shop, my wife's brand new Toyota bZ4X's 12v battery died - I had neglected to unsync it from the electrical utility's app. The utility's app seems to have been the problem all along!
