Had virtually all of my Kinro/Lippert frameless windows fail on my 2011 KZ Escalade in the first month of ownership in 2011. KZ replaced them all in 2011. A year later one of the replacements fogged and KZ replaced it N/C. The bigger problem is water leakage where the glass seals (or doesn't seal) against the window frame. Have been back to dealer and factory numerous times with no success. I now have duct tape over the worst glass seams to keep the weather out. Good luck with yours.
