2015 with 65K, and mine has joined the fail club.
Mine was a snap noise and the rear panel became stuck. If I push the front panel in with the rear panel, when I close the shade, the front will come into closed position. I can manipulate the rear section to close also, with assistance to the motor. I don't think mine has anything to do with the liner. It feels like a clip that holds it to the runner snapped.
$2850 is the estimate for me.
It is leave them closed, or if I open the glass, I have to leave it glass only, or climb in the back seat and futz with the panels. BS for just out of warranty. (I had 7yr/70k)
