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. I now have a third window unit that is experiencing the same problem. It is apparent to me Thor has acknowledged there is a risk present when they replaced the other units. In addition, Thor has issued a recall for several year models after my year model. It seems clear they are aware there is a risk of window failure in model years outside of the recall. Unfortunately, they are unwilling to address the risk and hazard.
