What's wrong?
The Webasto Hollandia 700, Hollandia 600, and Hollandia Tvs 900 sunroofs are roof glass assemblies installed in passenger vehicles. The glass panel is bonded to a metal frame, and that bond holds the glass in place while the vehicle moves, turns, and rides over rough pavement. It also helps seal the roof opening against wind and water.
In affected sunroofs, the adhesive bond between the glass and the metal frame can debond. That means the glue joint releases from one side of the assembly instead of keeping the glass locked to the frame. If the bond separates completely, the sunroof glass can detach from the vehicle.
Owners can see or hear signs before the bond fully separates. Watch for metal corrosion around the sunroof frame, new wind noise, vibration, visible separation between the glass and frame, or water leaking through the sunroof opening.
