NHTSA Complaint #11598796 — 2018 THOR MOTOR COACH PALAZZO

Hello NTSB, the frameless windows Thor used on my rv are all failing.. basically the adhesive used to glue the bottom rail onto the glass keeps failing. This week I had two windows fail. The top bunk window, and the emergency exit window. Both window (at separate times) failed while driving. Lucky I saw them break loose and my wife was able to grab the window before it flew off on the freeway and possibly caused a major accident or injury with flying glass at freeway speed. Again this is the 4th window failure in the last 3 years. All with the Same problem. Last summer I had the same problem with the bottom bunk window, however that window flew off somewhere in New Mexico. Unfortunately I have no idea if the large piece of glass flying off my rv at freeway speed hurt anyone or anything. I filed a NTSB report (just like this) last year, and the never received or heard anything back from you guys. A year later 2 more windows have failed. Reading other post in the palazzo Facebook page, window failure (as I’m describing) is a very common occurrence. So much so, the 2017 and 2016 units have the recall on the windows. However the 2018’s are not included in that recall, but are obviously having the same problem. Please investigate this. Thor and the windows manufacturer HELM, are aware of the problem. So much so they sent me a new window and frame for the one I lost at no cost. Taking with HELM, they said they see this a lot.
