NHTSA recall 08V055000

What's wrong: Failure of either the left or right hand side sunroof guide rail can occur when the sunroof is operated. Excessive stress can develop in the over-molded bracket which could lead to cracking during normal sunroof operation. If cracks occur and propagate in a certain area of the guide rail, fragments of the plastic over-mold material may detach from the guide rail and obstruct the operation of the sunroof.

Why it matters: The obstruction could cause the sunroof, when operated, to bind, twist, and potentially detach from the operating mechanism. If the sunroof is subsequently cycled and a vertical force applied, i.e., a customer manually aiding the roof to close or wind lift, the glass panel can become fully detached…

The fix: Dealers will install retention inserts to both sides of the glass panel guide rails. The recall began on February 29, 2008.
