2017 Grand Design Momentum

In early 2024 we noticed a binding on the bedroom slide, we took it in for service at Happy Daze in Ripon and the repair shop fixed the slide issue. After our next camping trip a month or so after the repair, we noticed a crack on the outside driver side of the front of the trailer above and below the bedroom slide. We had noticed a gap in the front bedroom cabinets in which we had attributed to normal wear and tear and had reinforced with screws and wood trim previously. In contacting Happy Daze again we brought it in for the new issue and realized that we were experiencing frame flex/failure. Happy Daze connected with Grand Design who sent a team out and did a goodwill repair of the issue, telling us it had been corrected. The SRT team from grand design welded and added additional lag bolts but did not address the outside cracks on the trailer. Because the trailer was well out of warranty and we were assured that the repairs made were adequate we accepted the fact that we would deal with the superficial flaws on the outside of the trailer. We covered the areas as best we could to prevent any water damage from occurring at those areas. A few months ago we noticed that the cabinets had cracked in a few areas and have continued to separate from the wall also rubbing a hole on the side wall. We returned to Happy Daze who pulled off the front cover and found broken welds and loose bolts on the frame work that was repaired in 2024. Grand design was contacted and has refused to make any additional repairs to make this vehicle road safe currently. We were informed to make a claim with NHTSA regarding this issue.

The contact owns a 2017 Grand Design Momentum RV. The contact stated that the exterior storage doors failed to close properly. The contact stated that the generator doors almost detached, and the front rubber trim hold was detaching. The RV was towed to the dealer, where several repairs were performed; however, the frame continued to fracture. The dealer advised the contact to park the RV. The RV was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was unknown.

This is a 43 foot fifth wheel RV. The frame near the front of the RV is showing signs of "frame-flex," or frame cracking. The attached pictures illustrate where the walls are shifting and creating wear marks; this is consistent with other RV owners experiences the same problem. This issue could contribute in further frame cracking that may result in significant property damage or even death. I plan to report this issue today to the manufacturer, Grand Design.
