The sunroof may become stuck in the closed position or require "help" moving forward and backward. The common repair is to replace the guides but often the problem will resurface again.Google+

Difficult to open and/or close the sunroof without manually "helping " it (by pulling it along its guides.)When open button is pressed, the window will lift as if it is going to work- but will not open further.I have checked the fuse that operates the window.I will be checking the motor that operates the window next .

Power sunroof has to be pushed up (helped) before it will open. When opening, it stutters, but does open from this point on.

I have not gotten it fixed yet as it just sticks a bit. If I push up on it while pushing the button to open, it works.
