2024 Grand Design Momentum Problems

The contact's friend owns a 2024 Grand Design Momentum Recreational trailer equipped with an Insignia gas range stove, Model Number: NS-RNG24SS9. The contact stated that after lighting the pilot light inside the oven, the contact closed the oven door and turned the oven knob. The contact stated that the stove then exploded, and the oven door flew open. The contact had not sustained any injuries. The RV and stove were not diagnosed or repaired by an independent mechanic or dealer. The stove manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 1,000.

During normal travel on a paved roadway, the wheel/hub assembly on the axle on the trailer fell off. This caused the axle spindle to bend and the wheel and hub assembly to fall off.

October, 2025: At around 1800 miles on the trailer we inspected one axle set (RR)of wheel bearings and brake backing plate/shoe assemblies. This was prior to a 1400 mile trip with the trailer. The trailing shoe was found to be cracked and had material coming off in chunks. Upon contacting and reporting this to the manufacturer they sent a replacement backing plate assembly, drum and wheel bearings. The planned trip was made with the old parts. The braking on the trailer wasn't the best but they did not fail. Skip ahead to 02-22-2026 and we took the brakes apart on the one we'd reported and noticed immediately that the friction material that had begun to come apart had done so even more. We then sent another message to manufacturer regarding this, them took the remaining 5 wheels and brake drums off the trailer. Several had either cracked or missing friction material. One assemble, LF, had been greased excessively and had grease in the brake actuation coil, shoes and drum. I again sent a message with pictures to the manufacturer. They got back to me pretty quickly and parts to replace all of the brake assemblies are being shipped. Our worry is that many more units have this same faulty brake friction material.

The contact owns a 2024 Grand Design Momentum RV. The contact stated that upon purchasing the RV brand new, the dealer hitched the RV to the 2024 Chevrolet Silverado 3500 HD. The trailer brakes warning lights illuminated; however, the dealer advised the contact that the RV could be driven off the lot. The contact stated while pulling the RV in the mountains at 50 MPH, the trailer brakes became inoperable. The contact was able to slow down the RV by depressing the brake pedal of the truck as needed. Additionally, the contact had hired a third party inspector, who had inspected the RV before it was driven off the dealer's lot. The inspector had informed the contact that the RV was missing safety pins and locking mechanisms, and that the roof was damaged; however, the dealer advised the contact that the RV was safe to drive without the parts and the parts would be provided later. The contact stated that all the beds of the RV had detached, and the beds frames were flapping against the walls while in transit, causing damage to the beds frame and to the walls. The contact stated that the failure had caused the whole RV to shudder while driving 40-50 MPH, which required the contact to exit the highway a. The RV was taken to the nearby RV dealer. The dealer detached the beds and laid them flat on the floor. The RV was later taken to General RV Center(14000 Automall Dr, Huntley, IL 60142), where the roof was rebuilt; however, the contact requested a trade-in due to safety concerns. The dealer depreciated the RV and rolled the depreciation into the payment of the new RV that the contact had purchased. The manufacturer was notified of the failure, but the manufacturer put the blame onto the dealer and referred the contact to the dealer for assistance. The failure mileage was 0.

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.

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!

The contact owns a 2024 Grand Design Recreational Momentum. The contact stated that after the RV was delivered, the brakes were inoperable, a slice was cut in the wiring harness with electrical tape covering the cut, the slide-out frame was out of alignment and unable to close properly, the awning had detached, and ABS was not equipped in the RV. Additionally, there was water intrusion in the RV, resulting in mold. A mobile independent mechanic replaced the brakes and wiring harness; however, the RV was not repaired. The manufacturer was made aware of the failure and denied five buyback claims. The contact had also filed sixty-two warranty claims. The failure mileage was approximately 2,700.

Axles were supposedly installed backwards. Suspension is not installed square under the frame and rv bounces violently behind truck. Storage doors have come open while in transit.

During normal travel on a paved roadway, the wheel/hub assembly on the axle on the trailer fell off. This caused the axle spindle to bend and the wheel and hub assembly to fall off.
