Webasto is recalling 1,109 Hollandia 600, Hollandia 700, and Hollandia Tvs 900 sunroofs installed on passenger vehicles because the adhesive bond between the glass and metal frame can fail. If the glass separates, it can create a road hazard or strike a trailing vehicle, and the dealer repair will be free once available.

What's wrong?
The recalled Webasto Hollandia 600, Hollandia Tvs 900, and Hollandia 700 sunroofs use a glass panel bonded to a metal frame. That bond holds the glass in place while the frame seals the roof opening and carries normal vibration, wind load, and body movement. The sunroof assembly depends on the adhesive staying attached to both surfaces.
On affected sunroofs, the adhesive bond between the glass and the metal frame can separate. The problem develops as the bond lets go around the frame, and full glass-to-frame separation can build gradually rather than all at once. If the bond releases completely, the sunroof glass can separate from the vehicle.
Warning signs include metal corrosion around the sunroof frame, new wind noise, vibration, visible bond separation, or water leaking around the sunroof. If you notice any of those signs, treat the glass as loose until it is inspected.

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, falling glass creates a road hazard, raises crash risk, or strikes a trailing vehicle. If your vehicle has an affected Hollandia sunroof, treat loose roof glass as a safety issue and schedule the recall repair. Repair will be free at any franchised Webasto dealer once available.
What should I do?
- Check your VIN to confirm your vehicle with a Webasto Hollandia 600, Hollandia Tvs 900, or Hollandia 700 sunroof is included in this recall.
- Contact Webasto customer service at 1-888-749-8632 for recall instructions and reference recall number 10V421 when you call.
- Ask Webasto which glass-to-frame adhesive-bond repair applies to your sunroof, since the defect lets the sunroof glass separate from the frame.
- Watch for warning signs before the repair, including metal corrosion around the sunroof frame, wind noise, vibration, visible bond separation, or water leakage.
- Avoid driving with a loose or separating sunroof glass panel until Webasto gives repair or inspection instructions.
What happens at the repair
Webasto is handling the repair process for affected Hollandia 600, Hollandia 700, and Hollandia Tvs 900 sunroofs. The filed remedy directs identified owners to Webasto's recall notice and affected vehicle list so Webasto can confirm whether the installed sunroof is included. Because the source remedy does not describe the exact shop repair, do not assume a glass, frame, or adhesive replacement step until Webasto confirms it for your VIN or sunroof. The final recall repair will be free once Webasto opens the remedy path for your vehicle.
