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.

The coach windows on the RV keep failing. Last year I had two windows fail on my drive to Wyoming. The sealant that hold the window bracket comes detached from the glass widow. When that happens the window flaps is the wind and if the window swing higher than 45 degrees, the window can slide off the top rail, and become a projectile for anyone traveling behind me. Since my windows didn’t fall off, I bought new sealant and reattached the rails back to my glass. Those two windows have been good since. Then this summer I lost and different body window (lower bunk). But this time, the window just flew off without me noticing. I sure hope it didn’t cause an accident or injury anyone. Lippert is the manufacturer of the window. And they have a recall on them, however the recall ends 2 month before my unit was built. So they say I don’t qualify for the recall. However I have had 3 windows fail for the sale reason and cause as the recall that ends 2 month before my unit was built. The recall window obviously needs to be expanded as many more units are effected. Talking with other owners of the same model on my Facebook group, this is a know problem. With a lot of failures. Someone is going to get injured when a window falls on the road and causes a accident or possibly even death.

THE FRONT CABINET ABOVE THE FRONT DASH INCLUDING THE STEERING WHEEL AND OTHER OPERATOR CONTROLS DETACHED FROM THE CEILING AND BEGAN FALLING DOWN. THIS OCCURRED WHILE THE RV WAS IN MOTION. HAD IT COMPLETELY DETACHED CONTROL OF THE RV WOULD HAVE BEEN LOST. THE SCREWS HOLDING THE CABINET FRONT PULLED OUT OF THE WHERE THEY WERE SCREWED IN ALLOWING THE FRONT OF THE CABINET TO FALL.*DT THE CONSUMER PROVIDED PHOTOS. *TR*DT*JB*DT CONSUMER SAYS THAT THERE WERE NO RV DEALERS NEARBY SO THEY REFASTENED THE SCREWS AS A STOP GAP MEASURE. DEALER AND MANUFACTURER WERE NOT CONTACTED. *DL
