NHTSA Complaint #11641945 — 2021 GRAND DESIGN MOMENTUM

I am experiencing upper deck frame flex which our manufacturer has unsuccessfully attempted to repair twice (Nov 2021 and Oct 2024). The manufacturer refuses to accept responsibility for our safety concerns and has ceased all remaining repair attempts which was communicated to us through emails. This excessive flex causes my cargo doors to open while traveling, damage to the supporting frame structures (frame cracks throughout), and the attaching king pin that no longer supports the weight of our RV as evidenced by the 1 inch drop when hooking our RV up to the tow vehicle. Multiple repair attempts have been made by the manufacture at the manufacturer's facilities however, each attempt has failed and is simply weakening the already weakened frame. The manufacturer has extended the warranty to its consumer base however, my contention is this is merely "optics" given their refusal to apply a "permanent" fix to our RV that IS currently under their extended warranty.
