2021 GRAND DESIGN SOLITUDE Structure Problems

The contact owns a 2021 Grand Design Solitude Trailer. The contact stated that while driving approximately 60-65 MPH, the cargo doors opened independently. Additionally, the contact stated that the built-in tables were detaching from the wall, and the wall panels were separating in the bunk room. The contact also noticed that the walls were separating from the floor. The contact related the failure to NHTSA Action Number: PE24029 (Structure). The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not notified of the failure. The failure mileage was unknown.

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.

My fifth wheel has extreme frame flex which caused compartment doors to come open while traveling sometimes allowing things to fall out while traveling. Having a screw driver falling out and hitting another car was a major concern. Grand Design has the camper to address the frame flex. I believe the frame flex was the cause as sometimes the latches wouldn't engage.

Bish’s RV in Boise has confirmed that our unit is experiencing frame flex again. Our RV is under warranty and we have been waiting for over a month to hear back from Grand Design. This began in January 2023, we took the unit to a service center for repairs, which took over a month. However, after towing just 45 miles, the issue reoccurred. We were then sent to McClain’s in Sanger, Texas, where SRT Chris found that lag bolts had been left out during manufacturing. He replaced the seal plates with thicker steel and made necessary adjustments. Now that this issue has happened a third time, I’m concerned that the breaking seal plates are a symptom of a larger structural problem. We've also had a cargo door open during transport, along with a broken leaf spring and suspension. At this point, I have little confidence that a proper repair is...

Side front cargo compartments have opened during travel. Left and right side in two seperate incidents. Cargo fell on highway in one incident.

Trailer is not manufactured in compliance of FCR Title 49 393.70 a,b,(ii), California Code of Regulations Title 13 and Cal.Vehicle Code. Coupling devices and towing methods, as it is a known fact that 5th wheel hitches are breaking frames. Hitch will flex vertically 1 to 3 inches when towing. If towing truck has USDOT and/or California BIT numbers on side of truck the trailer is bound to Federal and State Motor Carrier Laws as trailer is part of combination. Hitch weight is overweight by 106 lbs empty, see attached weight sheets and product sheet. Grand Design main sales phone number confirmed Max Hitch Weight is correct on sales brochure. We cannot legally install generator or washer dryer in front compartments as trailer will be at least 500lbs overweight on hitch. During trips, front cargo door and rear cargo doors have come unlatched. When trailer was purchased, brakes were not operating...
