What owners say
After day or two purchasing the car, I started getting notifications at the car battery was low eventually after two weeks it completely died, and I was locked out with no way to enter the car because they no longer provide a manual key in the key fob. Multiple chargers and charging with another car for hours with no luck to get the car back up once I finally did get the car open. Seems like the dealerships themselves are aware of this issue and they have no way of fixing it. They keep playing games and making circles about how they’re escalating they’re doing they’re doing that and they have not provided me with a loaner.
Battery drain which results in vehicle not starting. There have been a series of events that ended in my Carnival not starting. Purchased new on July 6, 2024. Picked up from to Dealership July 8, 2024 and drove home. The below events started Aug 2, 2024 1. Side mirrors didn’t “wake up” when I approached with key fob 2. Truck wouldn’t close (had to manually pull shut) 3. Received app notification when attempting to lock doors through app that battery was less than 40% 4. Received dashboard warning when attempting to start 5. Lights remained on for a few seconds after attempting to start 6. Vehicle wouldn’t start 7. Turn signal - Action required via app 8. Towed to Dealership 8/5/2025 a vehicle would not start
I have a dead brand new car after not driving it for 3 days. And, the dealer is unable to tell me how to get into it because the key fob does not have a physical key in it. This appears to be a slow battery draining issue that is being reported heavily online it appears on Reddit, Facebook and multiple forums related to the 2025 Kia Carnival EX and SXP.
Battery died within 2 days on purchasing vehicle. Took to the the dealer and they replaced the battery but said to keep key fob away 32 ft at night. I carry around a portable charger with me since so many other people are having this issue if not worse.
