Are there any common issues with the Kia Sorento's transmission?

I've been researching the Kia Sorento and I've heard some rumors about transmission issues. Can anyone with personal experience confirm or deny this?

I've had my Kia Sorento for 3 years and haven't experienced any transmission issues. I make sure to stay up to date on maintenance and follow the recommended service schedule.

I had my transmission completely fail on me after only a year of owning my Kia Sorento. It was a known issue with certain models, but Kia refused to cover it under warranty.

I haven't personally had any issues with the transmission, but I've heard of other Kia Sorento owners having problems. It's always a good idea to get any unusual noises or shifting checked out by a trusted mechanic.
