Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

To Whom It May Concern, I am submitting this complaint regarding Recall #21V-522 (NHTSA Campaign No. 21V-522) involving Lippert/Hehr windows. I own a 2019 Thor Motor Coach Challenger motorhome manufactured on 9/2018, which contains Lippert/Hehr windows that are exhibiting the same safety defect identified in this recall. Specifically, the adhesive bond between the glass and its supporting frame/rail has failed, causing partial detachment of the glass panel. While Lippert has stated that my windows are not covered because they were manufactured just prior to the official recall window, and that the defect is not a “seal failure” but rather a “rail detachment,” the functional hazard is identical: the glass panel is separating from the frame, creating a serious risk of detachment while in transit. I have already submitted extensive documentation to Lippert, including: •Photos of each affected window (interior and exterior). •Close-up photos showing the adhesive/rail detachment. •The official recall schematic identifying the part numbers of my windows, which match those identified in Recall #21V-522. Despite this, Lippert has refused to cover the repair under the recall, citing narrow technical distinctions and manufacturing dates. This refusal leaves me with multiple windows in my vehicle that present a significant public safety hazard consistent with the very defect NHTSA recognized in this recall. I am requesting that NHTSA review my case and determine whether Lippert is improperly limiting the scope of Recall #21V-522, and to require them to provide an appropriate remedy for my affected windows. Thank you for your attention to this matter. I am prepared to provide all supporting documentation, including photographs, correspondence with Lippert, and recall documentation, upon request. Respectfully [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
