On interstate 10 in Texas our rear driver side window just fell out. Could have been a hazard to any following vehicles. No unusual road conditions were to blame!
Visibility, Structure, Other or unspecified, Jan 21, 2026
Component Failures: Frame outriggers failed twice with broken welds and severe bending. Front bedroom emergency exit window detached during highway travel 1/20/26, struck RV and adjacent vehicle before shattering. Main entry door repeatedly opens during travel since 7/25, worsening. Floor sagging in multiple locations. All available for inspection except missing window. Safety Risks: Window detachment created highway projectile, potential damaged third-party vehicle. Door opening risks items ejection. Frame failures risk collapse, rollover, or trailer separation. Floor deflection indicates compromised integrity. Continuous sawdust shows ongoing deterioration. Professional Confirmation: Yes. Lippert (authorized facility) repaired frame 11/25/25 (Work Order WO-00230680, Case 6354938): re-welded outriggers, I-beam heat treatment, cross member re-welding, jack reinforcement. Same components failed after only 3,400 miles with worse damage, proving systemic defect. Manufacturer Inspection: Lippert inspected/documented failures per WO-00230680. Owner expressed concerns about re-welding compromised components; technician assured repairs would hold. Assurances proved false. Grand Design notified concurrent with this complaint. Warning Symptoms: No electronic warnings. Physical symptoms from purchase (8/24): continuous sawdust at floor/wall junctions, slide trim detachment with violent popping (mid-25), door opening (7/25), roof seal separation (9/25), outrigger failures (11/25, 1/26), window detachment (1/20/26). Progressive deterioration indicates fundamental frame design/manufacturing defect. Conclusion: Recurring catastrophic failures, failed repairs, and window detachment demonstrate systemic defects posing immediate danger. Vehicle unsafe. Request investigation into manufacturing defects affecting this model.
