What's wrong?
The Webasto Hollandia Tvs 900, Hollandia 600, and Hollandia 700 sunroofs use a glass panel held to a metal frame by adhesive. That bond keeps the glass attached while the vehicle moves, while the frame supports the panel and seals the roof opening against wind and water.
On the recalled sunroofs, the adhesive bond between the glass and the metal frame can debond. In plain terms, the glue line loses its grip. As the bond opens, the glass is no longer fully secured to the frame. If debonding becomes complete, the sunroof glass can separate from the vehicle.
Complete separation can develop gradually. Owners can see metal corrosion around the sunroof frame, wind noise, vibration, visible separation between the glass and frame, or water leaking around the sunroof.

A matching Webasto Hollandia model does not confirm inclusion. Check your VIN to confirm whether your specific vehicle has recalled equipment installed.
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. There is no warning sign listed before separation, so keep extra distance from other traffic and schedule the recall check promptly. Repair will be free at any franchised Webasto dealer once available.
