What's wrong?
The Webasto Hollandia 700, Hollandia Tvs 900, and Hollandia 600 sunroof assembly is built around a glass panel bonded to a metal frame. That frame holds the glass in position while the roof opening seals against wind and rain. The adhesive bond is the part that keeps the glass attached as the vehicle moves and vibrates.
On affected sunroofs, the bond between the glass and metal frame can separate. Once that debonding starts, the glass is no longer held to the frame as designed. If the separation becomes complete, the sunroof glass can detach from the vehicle.
This problem develops gradually. Before separation, owners can notice metal corrosion around the sunroof frame, extra wind noise, vibration, visible gaps in the glass-to-frame bond, or water leakage around the sunroof. Any of those signs means the sunroof needs inspection by the repair provider.

What's the safety risk?
If the sunroof glass separates, falling glass can create a road hazard, strike a trailing vehicle, and cause a crash. Until the recall work is complete, drive cautiously and contact Webasto about the repair path. Repair will be free at any franchised Webasto dealer once available.
