Please see update below...
In my Kia Telluride I had an issue with the right side mirror camera, I was driving in a highway and it suddenly started showing distorted image then it stopped working and showing only blue screen, the next day it returned to working normally, a week later I was driving in the same highway and the same issue returned.
The local dealer didn't find what the issue was and they say it was an error in the car computer and they erased the error and it should work fine but the issue still exist.
*******UPDATE********
I went to kia's dealer in mh area and after several attempts they finally discovered the problem, they said it was a loose t-harness for the right door, and they fixed it.
