Owner report 11419475 · 2021-06-03 (June 3, 2021)
The Hehr-Lippert windows installed on this Thor motorhome have a design flaw where the adhesive between the outer glass and mounting frame becomes weak when expose to the sun/heat and can fly off the coach at speed and become a trajectory. The Hehr-Lippert side windows installed on this Thor motorhome in the driver and passenger areas can fog between the glass causing poor side and mirror visibility.

Owner report 11539433 · 2023-08-18 (August 18, 2023)
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 w…

The rear emergency exit window fell off during travel. Being a large motorhome I do not know where or when it happened and was noticed upon arrival at home. It is likely it came detached in traffic. I do have the make or model of the window but the Thor DAX # is 0273323.

Owner report 11586377 · 2024-05-01 (May 1, 2024)
Recall 21-E-047 was a recall on HERH window assemblies. The window adhesion is faulty and causes the window to separate from the vent bracket. I experienced this with my Palazzo. While traveling this last weekend a window broke free and came close to smashing into the car behind me. An absolute nightmare. Not only a major distraction to the RV driver but a potential fatal hazard if the window smashes into a trailing drivers windshield. I contacted lippert and sent photos and VIN. I was advised my coach VIN didn't fit within the VIN seque…
