“Drivers side rear bedroom vent window has delaminated twice, first in oct. 2019 (replaced under warranty) and again in jan 2020 (still at dealership service awaiting replacement from lci/thor. Both times, I was fortunate to discover the separation before driving the vehicle during my pre-trip walkarounds, thus avoiding the danger of the outer glass flying off the rv and into traffic. Also in dec. 2019, the front right (passenger side) fixed dual pane window started to show fogging when exposed to direct sunlight (no action taken yet to replace it)”

“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 sequence they identified. …”

“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). …”

“floor of storage area is failing this could cause items in storage to fall out while driving. the items that fall out could be hit by the tires of the motorhome or hit another vehicle causing a serious accident.”

NHTSA complaint #11465560, filed 2022-05

“The Thor motorhome has several windows. The windows they installed are laminated windows, with two panes of glass and a seal or glue which connects the outer glass to the inner glass. The attachment method for the outer glass is ineffective. As a result, the outer glass pane comes loose from the inner and is prone to fall off or fly off at highway speeds. The risk is that the pane could strike another vehicle and possibly cause an accident. Already Thor has replaced two of the window units on this unit around 2021, not under warranty but as a customer courtesy. …”
