Update of Warranty Information
Condition
The customer complains of the windshield seal melting or deteriorating.
Technical Background
The observed condition can be the result of a material incompatibility between the windshield seal material and the
adhesive used for fixing the windshield. When these two substances come into contact, a chemical reaction occurs,
forming a melted and sticky appearance of
the windshield seal. It is important to note
that extended exposure to sunlight can make
this condition worse.
