What's wrong?
The Webasto Hollandia 700, Hollandia Tvs 900, and Hollandia 600 sunroofs use a glass panel bonded to a metal frame. That bond is what keeps the glass attached while the vehicle moves, flexes, and takes wind pressure on the road. The sunroof assembly depends on the adhesive holding the glass and frame together as one piece.
On these 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 recall information does not give a separate root-cause explanation, so the important failure point is the glass-to-frame adhesive bond losing its hold.
Owners can notice metal corrosion around the sunroof frame, wind noise, vibration, visible bond separation, or water leakage. Those signs mean the bond has started to separate and the sunroof needs recall attention.
