GRAND DESIGN Complaints

The front of our grand design momentum fifth wheel camper has sustained some structural failure. Our bedroom slide will no longer stay closed when driving down the road. Our storage doors will also open every now and then when we encounter rough bumps or rough roads. We began to notice some small damage inside the front bedroom of the unit as well. The camper has been untowable for nearly 6 months, with no help from the manufacturer. Even though the have issued an extended warranty for like issues.

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.

We bought our 2022 Grand Design Solitude 346FLS-R in March 2023. We have had numerous safety issues and concerns, and currently don’t feel safe towing it. 1. External locked compartments and entry door open while traveling. Risks: distraction, collision (passing vehicle or objects), quick maneuvering (to side of road), contents ejected onto road/vehicles. Resolution: Shops have tried to fix, but problem continued. I placed some screws to extend the latch plates. Concerned this is a “frame flex” issue, along with our floor separation, sheared screws, saw dust, etc. 2. Three axle/suspension failures. In 3/2024 and 12/2024, sudden/extreme tire wear was noted due to failed suspension (broken leaf springs, cracked equalizers). In 8/2025, while driving on [XXX], an entire wheel disappeared. We called the MI highway department afterwards and they had no reports of accidents or debris due to the wheel. Roadside assistance got us to a local repair shop that found the 3 other tires were badly worn/damaged, rear passenger side leaf spring cracked (3rd time), and remaining brakes "fell apart in chunks". The technician diagnosed a bad spindle. As the work was completed, the shop owner stated "I don't think your suspension is fit for this rig. It already appears max'd out." Risks: The entire wheel flying off on the highway could have easily killed someone. Suspension failure while rolling could lead to tire blowouts/catastrophic damages/major accident. Resolution: Suspension repairs made/tires replaced. Recently stopped in at Grand Design in Elkhart, IN to speak with the Customer Service Director about these safety issues. The GD shop is booked until December, but a frame and suspension inspection at a GD dealer was authorized. CW Direct in Elkhart completed the inspection, found a frame crack and assessed the 7K suspension as insufficient. Still no resolution and we now have not been able to live in our home for over two weeks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
