What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The U bolts on my RV suspension failed which let all the leaf springs fall out. My family was very lucky that no one was injured or killed. Please see the attached photos.
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!
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.
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.
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.
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 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.
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.
