Issue: On certain motorhomes equipped with frameless windows, the adhesive that attaches the vented portion of the windows may fail.

Corrective Action: Thor Motor Coach will notify owners by mail and instruct you to bring your motorhome to an authorized dealer or service center to inspect and replace the vent window glass, as required.

Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a dealer to update the motorhome's Multiplex system.
