GRAND DESIGN Complaints

The contact owns a 2021 Grand Design Momentum RV. The contact stated that the RV had experienced a failure with the frame, causing the RV to become unstable while being hauled. Additionally, the frame was positioned on the pin box inside the unit, and the lag bolts and screws loosened, causing damage to the interior cabinets and trim. The RV was taken to the local dealer, who replaced the bolts and screws, but later, while using the RV, the failures reoccurred. The RV was not yet repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

The contact owns a 2019 Grand Design Solitude RV. The contact stated that while the RV was parked, the contact performed an inspection of the RV and noticed that the RV was sitting unevenly. The contact stated that upon further inspection, the contact became aware that the rear driver’s side leaf spring was cracked. The contact replaced the rear driver’s leaf spring. The contact stated that while continuing his trip, the bedroom slide-out fractured and detached. In addition, the contact stated that while hitching and unhitching the RV, there was an abnormal flexing of the frame. The contact stated that the next day while hitching the RV, the contact noticed a separation in the front under section and determined that the frame was flexing at the joint. The RV was driven to the residence. The RV was taken to the dealer, upon the manufacturer's request, and it was diagnosed with several frame fractures. The contact was informed that the frame needed to be re-welded. The travel trailer was not repaired. The manufacturer was made aware of the failure, but denied the repair to be covered under Technical Service Bulletin: 24001. The contact was informed that the repair was outside the Technical Service Bulletin criteria.

The contact owns a 2021 Grand Design Solitude Trailer. The contact stated that while driving approximately 60-65 MPH, the cargo doors opened independently.

The contact also noticed that the walls were separating from the floor. The contact related the failure to NHTSA Action Number: PE24029 (Structure).

On 6/30/25 I originally reported the Safety Issue (Case #11670309). The engine dies while driving. The display indicates "Low Fuel Pressure" and the Check Engine light comes on. The vehicle has been to the Ford Service Center several times for repair. They have validated the issue and have documented the DTS codes. Some components have been replaced or overlaid. My and other's safety has been put at risk. When the engine dies the vehicle has no power steering or power brakes. Pulling over to a safe location is difficult or not available. Most recent event occurred on 8/10/25.

I am experiencing symptoms, consistent with excessive frame movement and structural failure in my 42 foot fifth wheel toy hauler RV. We have been monitoring this for the time we have owned it just over six weeks and have noticed an increase and symptoms that research shows indicate there is a problem.. we are seeking professional inspection and guidance to establish the scope of it and hopefully catching it at the earlier side in order to hopefully deal with the issue easier than after a total failure. The symptoms include 1- the interior upper section horizontal lag bolts that hold the camper walls to the frame all had come loose completely. There were four on one side and five on the other. 2- the underside curved fillon panel by the pin box is ripple and curved, and shows movement 3- the left and right sides of the camper towards the front are becoming out of square with the rest of the camper and the seals around the doors are showing larger gaps and looking more out of square 4- interior doors and exterior doors of the camper are all experiencing difficulty latching and are becoming out of square to the original structure 5- there is a changing of the distance, measurements both in height, and in relation to the lower frame members from the pin box where the camper tows from. And what appears to be some twisting out of square. 6- front panel door is buckling in the center and will no longer close geometry of the opening has been compromised It is clear that we are experiencing frame structural failure between the area where the camper toast from in relation to the main frame of the camper

The right side leaf spring hanger broke from the frame while traveling causing the trailer to lean heavily and pull to the right side nearly hitting an 18 wheeler that I was passing. I received a customer satisfaction campaign letter from Grand Design 3 days later in regard to cracks in the I beam frame above the spring hangers for all Imagine 2910BH models produced between 6/24/2020 and 6/14/2023. Grand Design said that they have concluded that condition does not present a safety hazard. Having a suspension component fail on a trailer is a safety hazard.

Current Symptoms (post-repair): Excessive Frame Flex: - Pin Box Flex, including cracking sounds - Bulge in bottom corner of front driver side slide - Decal ripples - Screws snapping - Door alignment issues - Sawdust on interior furniture after moving - Pinch molding issues - Screws backing out Repairs were made on the unit in Feb 2025, however the above symptoms are still present (or have worsened) since the repair was completed.

The front left slide stopped working 3 weeks ago. Something appeared to be wrong with the wall but I was not sure. Yesterday I noticed the front left portion of the frame was flexing a significant amount. I started inspecting the frame and I am seeing broken welds

After the trailer collapsed, I’m deeply concerned for my children’s safety and the safety of others. Despite raising these issues, the manufacture Grand Design has deflected responsibility and refused to act, even while under warranty. I kindly request immediate attention and a formal response. I previously brought it to Grand Design in Elkhart, Indiana while it was under warranty, but they declined both inspection and repair. I am really struggling with why RVs are not federally regulated. My trailer poses serious safety risks to my family and others on the road due to the following issues: 1) Frame and Structural Failures: - Trailer collapsed when the frame broke holding the jacks - Welds breaking - Possible I-beam twisted (still need to confirm though) - Screws falling out while driving; risk of tire puncture and skirt/fender detachment - Driver-side outer wall separating from inner wall (gap large enough to fit a hand) - Main doors and cargo doors not staying closed during transport - Floor sinking in kitchen and bunk room - Trim detaching; walls bowing outward - Walls trimmed short five times, due to walls sinking with the floors from weight of roof - Severed screw heads on driver-side slides from excessive frame flex - Bathroom and hallway walls bowing - Sawdust on floor after each move - Master bedroom door damaged from wall bowing 2) Safety Concerns: - Brake breakaway system failed (now repaired) - Propane leaks - Wheel loose and balding due to improperly set crown bolt - Smoke and carbon monoxide detectors missing in bedrooms - Water pipes leaking onto electrical wiring (potential electrocution and/or fire) - Breaker box improperly wired (fire concerns) - Grounding issues affecting AC display and tank readers - Fridge leaking water inside (concerned about black mold) - Front jacks uneven and unstable and other issues too.
