Webasto is recalling 13 Hollandia Tvs 900, Hollandia 600, and Hollandia 700 sunroofs because the adhesive bond between the glass and metal frame can separate.

What's wrong?
The Hollandia Tvs 900, Hollandia 600, and Hollandia 700 sunroof assemblies use a glass panel bonded to a metal frame. That bond keeps the glass seated in the roof opening while the vehicle moves, flexes, and meets wind pressure. The metal frame gives the glass structure, and the adhesive keeps the two pieces working as one assembly.
On affected Webasto sunroofs, the adhesive bond between the glass and the metal frame can debond. If the bond separates completely, the sunroof glass can detach from the vehicle. The problem develops at the glass to frame joint, so the concern is not the switch or motor. It is the physical attachment holding the glass in place.
Owners can notice metal corrosion around the sunroof frame, extra wind noise, vibration, visible bond separation, or water leaking near the sunroof. Those signs mean the bond area needs inspection before the glass separates.

A matching sunroof model does not confirm inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
If the sunroof glass separates, it can fall into traffic, create a road hazard, strike a trailing vehicle, and cause a crash. Confirm your VIN and keep extra space around other traffic until the repair path is set. Repair will be free at any franchised Webasto dealer once available.
What should I do?
- Check your VIN to confirm whether your vehicle has a Webasto Hollandia Tvs 900, Hollandia 600, or Hollandia 700 sunroof included in this recall.
- Call Webasto at 1-888-749-8632 if you did not receive the October 8, 2010 safety recall notice.
- Ask Webasto how to complete the free sunroof-glass bond repair that keeps the glass attached to the metal frame, and reference recall number 11V501.
- Inspect the sunroof area for metal corrosion, wind noise, vibration, visible bond separation, or water leakage until Webasto gives repair instructions.
- Avoid driving with a loose or leaking sunroof glass panel; call Webasto before moving the vehicle if the glass shows separation.
