Kia Carnival 2025 Problems. I’ve seen a lot of posts about battery drain issues with the 2025 kia carnival. Charger said battery had 4v, wouldn't take a charge.
Hi everyone, i’ve noticed a recurring battery drain issue with my 2025 kia carnival sx, and it seems like many of you are experiencing the same problem. Confusion over self isn’t a deal killer at car of the year, but the kia’s faceplants against our criteria are, and the 2025 carnival’s new look and powertrain don’t break those falls.
