I’m sorry you’ve had so many personal and Kia troubles,
@Bev.
If I may offer a few suggestions...
1) Get your own lawyer and have them help you get through your own situation. Don’t worry about rallying others or figuring out a class action. Just worry about your own Telluride and how you can get help. As I mentioned previously you can probably find a lawyer to help you “for free” (if they’re successful, Kia will have to pay their costs).
2) Or, trade it in for something else. Tellurides are holding value right now and you won’t take much of a loss (if any). Go find another vehicle you like and get that instead.
It sounds like you will lose a lot of time, money, and sleep fighting with the service department and Kia, and will likely not get far with them. Their tune is not going to change overnight - it just is what it is. Let a lawyer handle it for you, or give up the T and let it be someone else’s problem.
