Cause
This condition may be caused by the anti-pinch feature activating as a result of a tight interface condition between the sunroof tracks and the mechanical
arm assembly.
Correction
Important
DO NOT replace the sunroof frame when the above condition is noted.
Important
If the sunshade spring tension releases, it will be necessary to rewind it. Refer to Step 1 of the installation procedure within Sunroof Sunshade
