2024-2025 GRAND DESIGN MOMENTUM

2025 GRAND DESIGN MOMENTUM Complaints
In early November 2025, while towing our 2024 Grand Design Momentum 344M M-Class fifth wheel toy hauler to a family Thanksgiving gathering, the rearmost driver-side leaf spring fractured and failed during travel. The trailer was towed by a 2024 Ram 3500 dually, properly rated for this unit, operated within all load ratings, and driven at normal cautious speeds at the time of failure. The failure rendered the trailer immobile and unsafe to move. It has remained in storage since the incident because the damaged suspension cannot support safe relocation. A leaf spring is a primary suspension component that is not customer-serviceable and not owner-maintained. The remaining leaf springs on the unit were inspected and are in good condition, indicating the failure was isolated to the defective spring rather than a result of abnormal use, overloading, or environmental exposure affecting the suspension system as a whole. This points to a manufacturing defect in the failed component. The trailer was purchased new from an authorized dealer (Blue Compass RV) in October 2024. The spring failed only weeks after the one-year factory warranty expired, at an extremely low service age for a primary structural suspension component. Safety concern: This failure happened at low speed, allowing a controlled stop without incident. Had it occurred at highway speed, likely consequences include sudden loss of trailer stability, axle and tire damage from the collapsed corner, trailer sway or jackknife, tire blowout, and potential loss of control of the tow vehicle. A loaded fifth wheel toy hauler of this size presents a severe hazard to occupants and surrounding motorists if suspension fails at speed. I am filing this report so NHTSA can track potential defect trends on Grand Design Momentum fifth wheels. Other owners of this model and model year may be at similar risk.
