“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.”
NHTSA complaint #11664760, filed 2025-06“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. …”
NHTSA complaint #11643988, filed 2025-02“Frame failure. We had a fixed window fall off. Grand Design sent me a replacement window but I had to pay to have it installed. Then I had a trim piece fall off of the front-side and the identical piece on the opposite side was starting to come off. We also had sawdust appearing upfront when we would arrive to our destination and the front floor was starting to make noise when we walked. I also noticed the under-covering around the rv hitch going up into the rv when I hooked it up to my truck. Several screws have sheared in the compartment door frames. …”
NHTSA complaint #11647009, filed 2025-03“I was informed to reference this code PE24029. 2021 5th Wheel - Grand Design Solitude 310GK. Frame cracks and separation. June 2025, contact made with Grand Design and they approved for us to obtain a welder. We did. It did not correct the issue and we contacted Grand Design again. Our Unit has been in the repair shop since December10, 2025. Back and forth emails with Grand Design. Sides need to be taken off to get to frame issues and make a repair. Would love for representative from NHTSA to come and look at our unit. The lower portion has been dropped, and you will be able to view. …”
