GRAND DESIGN Complaints

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.

October 2025 we had just left the highway and was on a heavily traveled back road going home from the mountains. My husband felt a jolt and thought we had blown a tire. But he checked the tire monitor and it was fine, then he checked the side view mirror and saw that the camper was off the road and almost hit a speed limit sign! Luckily we were near a less traveled side road and pulled off, still in the road as there were no shoulders. He discovered the right rear spring came apart and the rear axle slid back along the right rear landing gear. We were 6 miles from home so my husband stayed with the camper and I got a ride home to get our car. He was stuck there for 23 hours until the mobile tech got the camper well enough to make the 1 hr and 15 min trip to the nearest dealer. Once there, we were told that prior to us taking ownership, there was a recall on these axles and the "work was done and was satisfied". Per conversations with Grand Design, that issue is confidential between them and the dealer. We just received the camper January 12, 2026 after all repairs were done. Also, the Vin given to us on the build sheet was wrong and the camper year on the invoice should say 2024, not 2023. FYI.
