What's wrong?
The Hehr 6400 Series window on the 2018-2019 Nrc Motor Home is a frameless thermo-pane window with a vented section. The adhesive bond is supposed to hold that vented portion to the window assembly while the window seals the coach opening and allows ventilation.
On affected motorhomes, that adhesive bond can fail. When the bond lets go, the vented part of the window is no longer held the way it was designed to be held. NRC reported 31 of these windows already installed across 7 motorhomes sold through its dealer, all tied to the Hehr 6400 Series window supplied for this recall.
There is no warning sign before failure. Do not count on a sound, leak, or visible change to appear before the adhesive bond releases.
Who's affected?
The window vent is listed under both recreational-vehicle equipment and vehicle structure, so each model year appears once for each component area.

What's the safety risk?
If adhesive fails, the vent portion of the window can detach from the motor home, increasing crash or injury risk for people in or near the vehicle. Avoid driving with a loose, rattling, or separated vent window, and schedule the inspection soon. Repair is free at any franchised Nrc dealer.

What happens at the repair
At the dealer, an Nrc technician inspects the Hehr 6400 Series windows and replaces the window vent if the inspection shows it is needed. The recall repair is free, including parts and labor. If you have already paid for a related window vent or adhesive repair before the recall notice, NRC has a general reimbursement plan on file. Bring documentation of the paid repair and ask the service desk or NRC customer service how to submit it under that plan.
