It's not just 2015s. It affects 2016s as well. Basically when my free five years of myUVO was over (September 15th, 2021), it stopped working and when I inquired I got the "3G modem" story. The gist of my conversation with UVO support on the phone was "we knew it we were going to stop supporting it, we didn't warn you, we aren't going to offer a solution for your car — just deal with it".
To say I was not pleased is an understatement, and up to that point I was all over getting another Kia when we decide to replace this one (or even our 2013 Mazda3). Now I'm not so sure.
My battery is dying. How they handle THAT once it clearly falls below the 70% capacity threshhold (it is very close now) will ultimately determine if I ever consider buying another Kia.
Since September 15th I have not been able to connect to my car with the app, nor is there a path to purchase further access to UVO and keep using it. Grrrrrrr.
