The pin box is flexing to the point that its damaging the inside of the RV. I made various videos and provided them to the manufacturer. Based on the movement and damage the unit should not be moved until it has a professional inspection. Its possible that I have frame flex due to broken welds. The Manufacturer has asked it to be towed to a dealer for further inspection. I do not feel safe to do so in fear if it fails completely and causes damage or injury to others. Local dealer does not perform any repairs or inspection of structural damage.

This trailer has frame flex in the gooseneck area to the point it is damaging the cabinetry in the front of the trailer. I have been in multiple momentum trailers with this problem and the dealership just wants me to trade it in or charge an astronomical amount of money to try and fix. It’s a known problem that everyone needs to be aware of.

This is in addition to safety report #11540112. While further inspecting the trailer, the right rear shackle bolt was also found to be broken in half. The spring was still on, but it was probably working its way out, which would have cause the same failure as the left side, in the original report.
Suspension, Aug 22, 2023
Left rear wet bolt sheared mid-bolt at the hole where the grease comes out to grease the sleeve in the spring eye. Spring was sliding side to side, causing the shackle hanger to bend and the spring to detach from the shackle. I have Summo springs on the trailer, and the one on the left rear took the weight of the trailer, and may have prevented further issue's. This occurred on the freeway at approximately 65 mph. Safety concern would be uncontrolled axle due to the spring holding the axle not being attached to the frame, and possible uncontrolled swaying.

It is a common issue with the Grand Design Momentum G-class travel trailers where the interior floor and possibly the frame are flexing so much that is causes the laminate flooring to lift and separate from the plywood underneath. Bubbles in my laminate flooring were found during our initial walk through when our trailer was purchased, I was lead to believe that it was just a simple adhesive issue, but have since found from research that this is a common issue with all the g-class trailers. Many people on the Grand Design facebook pages have experienced the same exact issue, in the same exact areas as mine. Several have had them "repaired" to find out that the problem reoccurs. I am truly concerned about the structural integrity of the trailer as I believe that if the frame is flexing to this extent, that there is a lot of potential for it to become a catostrophic failure in the future while traveling down the road, putting myself and others in potential danger. Metal can fatigue and crack over time from being flexed. Bluedog RV (Portland, OR) has seen this issue several times, and has helped customers get their trailers repaired by a company called Fibrenew. I have e-mails from Bluedog confirming that they know a problem exist, but they claim they do not have anyone capable of fixing it, and do not know of anyone who can fix it. Fibrenew no longer is willing to do the repairs as they feel they can not adequately repair them, and they believe it is a structural integrity issue caused by Grand Design engineering. Our trailer was recently taken to Bluedog RV to have this fixed, but it is unknown what they did. The bubbles in our flooring still exist so it is my belief that they did nothing. It has never been inspected by anyone else. Files attached with file names 1,2 and 3 are of my trailer. The other files attached are supporting documents.
Service brakes, Aug 6, 2022
Bolts holding brake caliper assembly to the axle apparently loosen and fell out while on the highway. This caused the caliper to drop, resting on inner part of the tire rim, leaving approximately half to one quarter of the caliper on the disc. Caliper caused significant gouging on the rim. During braking, the caliper was prevented from spinning during brake application due to it hitting the axle u-bolt retention plate on top of the leaf spring. In the very limited backing, the hydraulic line held back the caliper. Safety issues are the complete lose of the hydraulic system, causing the complete lose of trailer brakes. The caliper gouging the tire rim could have caused the rim to break, with the result of the tire departing the trailer on the highway and hitting another vehicle. Issue was found when I noticed metal flakes (tire rim) in my driveway where I backed my trailer to park it. Following the flakes, I discovered the issue. Grand Design, and axle/brake manufacturer Dexter notified via email. No response as of yet. Hydraulic brakes were factory installed at the time of manufacture.
