Battery went dead. Been at dealer 2 weeks. They are waiting to hear from Kia but nothing is being done.
There seems to be a very common problem of the 2025 Kia Carnival having a battery drain issue, leaving people stranded. I had a dead battery today with only one month and 300 miles of use. Thousands have had the same experience and have discussed this on various forums.
12V Vehicle battery drained. Unable to start Vehicle.
I'm getting an alert in the car app that says low battery and will not perform any lock/unlock/start, etc features. It says the battery level is under 40%.

In the general design of the Kia Carnival, among other vehicles from the same manufacture (i.e. Kia Sportage) and different manufacturers (i.e. Chevy Bolt), the false taillight cluster has created a safety issue when signaling. With specific mention of the turn signals being in the lower third of the vehicle height, and not in the taillamp cluster, drivers may not ever see the turn signals from the rear of the Kia Carnival, as most drivers are looking at the large taillamp cluster, not the bottom of the rear bumper for turn signals. The poor visibility is further enhanced when combined with the height or size of other vehicles (trucks with lift-kits, large front end vehicles, or large A-pillars) or poor driving from either the vehicle mentioned, or others. Attached photo taken from the Autopian [XXX] ) as a visual reference. No warning lamps appear, and no failures occurred, as it is normal function. This is a manufacturer-created/designed problem. I believe it was done intentionally by the manufacturers to circumvent other design limitations on signaling lamps not being placed on moving surfaces such as liftgates or trunks, and thus crated a new safety issue with large false taillamp clusters that are just the dim lights for illuminating the vehicle.

I purchased brand new 2025 Kia Carnival SX less than 2 months ago and it is back at the dealership for service for the second time. First time it had an airbag light stay on the dash and the battery kept reading low voltage and would not allow us to use any features on Kia Access app such as remote start and 360 view. The dealership fixed the airbag light but did not find any electrical issues with battery after testing. The car is driven daily and after sitting for approximately 16 hours the car battery is completely dead. Tried to do a quick jump and would not crank over. I am convinced it has a parasitic draw. It is currently at second service center in hopes of a resolution. So far Kia has not been very supportive.

Purchased brand new, went home to put car seats in and that's when we discovered the rear sliding door did not lock. Took the vehicle in on the 7th, took until the 23rd for it to be "fixed". Picked up the vehicle came home and the car now does not lock again. Kia customer care team has been little to no help and it was suppose to be escalated to the Kia escalation team but we have yet to hear from them.
Started about a couple weeks ago. Just bought my car and my battery drained 3 nights in a row. Had to jump start it Found out some fan run, when car is off, hours after it has been parked.
