On June15, 2025, the passenger’s side vent window glass partially delaminated from the actuator assembly while driving, damaging the actuator and window glass. The front passenger window has never sealed properly since we purchased the RV new. Newmar was notified of this in August 2021, when the coach was returned to Nappanee, IN for warranty repairs. After the window failure, I discovered that Lippert/Newmar issued an NHTSA Recall for these windows on September 8, 2021. The recall notes the issue as being: “the adhesive that bonds the vented portion of the window may fail. Adhesive failure may cause the vent portion of the window to detach…”. We did not receive this recall notice from Newmar. This window, part number 757205, is covered under Lippert HEHR6400 Series Window Vent Recall, NHTSA recall number: 21E047. I contacted Lippert immediately following the window failure on June 16, 2025. After being provided photographic documentation of the window failure, as well as confirmation of the defective part number, Lippert issued case number: 5952303. On June 18, 2025, Lippert instructed me to contact the OEM (Newmar) to arrange inspection and repair of the recalled window with an authorized dealer. On June 18, 2025, I contacted Newmar, who denied responsibility for the recall defect claiming the window had been inspected in August of 2021. When I informed Newmar that I would be filing a complaint with the NHTSA, I was issued a Newmar case number: 00989760. Since June 18, 2025, I have contacted every authorized Newmar Dealer within a 250 mile radius, providing them with: the recall information, Lippert and Newmar case numbers, and the part number for the recalled defective window. To date, no dealership has responded or even contacted Newmar for authorization. On July 9, 2025 I again attempted to contact Newmar to progress the matter and have yet to receive any form of reply. My experience with Newmar is that this recalcitrance is the norm.
