Recall 12V121 affects 26 Webasto Hollandia Tvs 900, Hollandia 700, and Hollandia 600 sunroofs for glass separation. Webasto handles the free repair.
Webasto is recalling 26 Hollandia Tvs 900, Hollandia 700, and Hollandia 600 sunroofs installed as original equipment because the adhesive bond between the glass and metal frame can debond. If the glass separates, it can create a road hazard or strike a trailing vehicle and raise crash risk. The Webasto dealer repair will be free once available.

What's wrong?
The Hollandia Tvs 900, Hollandia 700, and Hollandia 600 sunroofs use a glass panel bonded to a metal frame. That adhesive bond holds the glass in place while the vehicle moves and helps keep the roof opening sealed against wind and water.
On affected Webasto sunroofs, the adhesive bond between the glass and the metal frame can debond. As the bond lets go, the frame no longer supports the glass as designed. If the glass separates completely from the frame, it can detach from the vehicle while driving.
There is no warning sign before failure. Owners can still notice signs that the bond is already coming apart, including corrosion around the sunroof frame, wind noise, vibration, visible bond separation, or water leakage.

What's the safety risk?
Separated sunroof glass can fall into traffic, create a road hazard, strike a trailing vehicle, and increase crash risk. No warning sign is listed before separation, so confirm whether the installed Hollandia sunroof is included and arrange the recall repair.
