Webasto is recalling 1,110 Hollandia 700, Hollandia 600, and Hollandia Tvs 900 sunroofs installed on passenger vehicles because the adhesive bond between the glass and metal frame can debond.

What's wrong?
The Webasto Hollandia 700, Hollandia 600, and Hollandia Tvs 900 sunroofs are glass panels mounted in a metal frame in the roof opening. The frame holds the glass in place while the vehicle moves, while the seal around it keeps wind and water out of the cabin. That bond has to stay tight because the glass is exposed to vibration, weather, and air pressure at road speed.
On affected sunroofs, the adhesive bond between the glass and the metal frame can debond. That means the glue joint lets go, so the glass is no longer fully secured to the frame. If the bond separates completely, the sunroof glass can detach from the vehicle and create a road hazard.
Before full separation, warning signs include metal corrosion around the sunroof frame, wind noise, vibration, visible separation between the glass and frame, or water leaking into the vehicle. Treat any of those signs as a problem with the sunroof assembly.

What's the safety risk?
If the sunroof glass separates, it can fall into traffic, create a road hazard, or strike a trailing vehicle. That increases crash risk for the vehicles behind you. Confirm whether the installed Webasto sunroof is included and arrange the recall repair. Repair will be free at any franchised Webasto dealer once available.
