What does your owners manual say? You're a 2017, so you should still be under warranty right??
It's important to follow the maintenance schedule while the cars still under warranty. If you deviate from it and something happens to go wrong with your transmission, you've given the dealership a reason to deny your warranty claim for the repairs. They know what trans fluid should look like with X amount of miles on it. And put all your receipts in a shoe box or scan them in case you have to prove you adhered to the maintenance schedule.
The other reason to follow the mfgs maintenance schedule is the design engineers spent a lot of time and money coming up with the optimal fluid change intervals. You're not going to improve upon that and trying to save a little bit of money by stretching out the change interval is foolish when it comes to the transmission.
Fwiw, the manual on my Sedona calls for trans fluid replacement every 16 months. I hate the fact that I have to replace it every 16 months but you know what I hate more?... having to replace/repair a transmission. So I do it at home to save money and use Valvoline MaxLife multi vehicle. The product information sheet says it's a direct replacement for Hyundai/Kia SP-IV. I also put a bottle of Lubegard's trans additive because my trans has 160k miles on it.
So far, so good. Even with 160k miles on it, it runs like a dream. No leaks, no funny sounds, no hard shifts, no slipping - knock on wood. ...
(sorry if all this is redundant for ya. I thought it was worth mentioning just in case)
