Recall 21V571 covers 4,106 2018-2021 Newmar motorhomes for window vent adhesive failure. Repair is free at any franchised Newmar dealer.

Newmar is recalling 4,106 2018-2021 recreational vehicles, including Bay Star, Dutch Star, and Essex models, because adhesive that bonds the vented portion of a window can fail. If the vent section detaches, it raises the risk of a crash or injury, and Newmar dealers will complete the free recall repair.

What's wrong?

The window vent on these 2018-2021 Newmar motorhomes is the opening portion of the side window. It is bonded into the window assembly with adhesive, so it stays attached while the vent opens, closes, and rides through vibration on the road.

On the affected Hehr 6400 series window vents, that adhesive bond fails. Once the bond lets go, the vented portion of the window no longer stays secured to the motorhome. NHTSA campaign 21V571 ties that separation to increased crash or injury risk, because the vent section can detach from the vehicle while it is in use.

There is no warning sign before failure. Owners should not rely on a rattle, looseness, or visible gap to confirm the problem, because the recall record does not identify an advance symptom before the vent separates.
