I am having the frame flex issues as well as others. I’m not getting anywhere with grand design. The doors come open when traveling if not strapped from the inside. Pin box on the hitch moves excessively, interior panels are moving in the front, middle and rear of the trailer.

There are several things starting off with frame flexing issue causing numerous of parts to fail and move out of place. The manufacturer did a repair of this and my confidence in it being repaired correctly is very low. I do not feel safe towing this RV anywhere. Second, the broken leaf spring on the front axle. This could have caused the vehicle to lose control and cause a serious accident. It has been repaired. We have had the entry doors come open on us during towing. Nothing was lost from this. Lastly, the master bedroom slide has come out about 3 inches during travel. They repaired the inside bottom brace at the service center.

The contact owns a 2022 Grand Design Momentum. The contact stated that there was sawdust in the trailer and the frame was sinking. The contact stated that the cabinets were loose and were detaching from the frame. There was evidence that the frame was flexing. The contact noticed a lot of movement and bending with the frame. The contact stated that the front hitch and furniture were detaching from the walls. The screws were not properly torqued. Additionally, there was water entering through the slides. There were no warning lights illuminated. The local dealer was not contacted. The RV was not diagnosed or repaired. The manufacturer was contacted. The failure mileage was unknown.

Multiple systems failed on this unit. Trailer Brake failure—The rear trailer brake wires were discovered to be severed inside the wheel drum from the factory. For the first year of use they were inoperable. This was suspected and confirmed with a thermal camera. The tow vehicle also alarmed “Check trailer brakes” while driving. A dealer inspected them and found the wires severed. This was repaired. Suspension failure—the rear driver side leaf spring broke on a paved highway 9 months after purchase. Pulled over immediately to inspect the issue and repair it. On 2 other separate occasions, we found broken wet bolts (after the unit was sitting in one place, unmoved for weeks). Also a cracked equalizer was replaced under warranty within the first year. The front passenger side leafspring also broke on an empty unit. Frame Failure & opening baggage compartment doors, slide out backing out in transit—symptoms of excessive upperdeck flex and frame failure began immediately upon purchase. Baggage compartment doors frequently open in transit. This has been a significant safety risk to the operator as well as other drivers. On more than one occasion the doors open in dense traffic in the middle of a city with nowhere to safely pull over. None of the contents of the compartment has fallen out to our knowledge, but could very easily fall out since none of the doors can be adequately secured. One door was replaced, but the issue not resolved. Upon further inspection, there were severely broken welds in the frame of the unit. The unit has sustained over 22 hours of welding on it to repair and reinforce the damaged frame. However, this has been repaired a total of 3 separate times. There is no guarantee that the repairs will hold moving forward. Also a result of the broken frame, the slide out began backing out in transport. Before leaving, the slide out was fully retracted and measured. Upon arrival the slide would be backed out 0.5-1” from the pre-departure measuremen

This unit is suffering from frame failure. Cargo doors have started opening on the freeway, cabinets are rubbing the wallpaper from frame flex, the forward floor has started squeaking, the forward lower exterior trim panel on the drivers' side is buckling, the forward walls have started creaking and popping when hitching up/unhitching and the pin-box "sinks" more than it ever did in the past when hitching up. I am very worried since these are all symptoms of frame failure. I've taken the unit to an authorized Grand Design repair center and so far, am not getting any support from Grand Design to actually fix the frame, the root cause for all of these symptoms. I'm worried if I accept the trailer and continue to use it, the problem will progress and we could end up with a complete failure while on the freeway.

The front frame has been in for repairs before for flexing issues/excessive movement. We have had a door pop open during travel and suspension parts break (hanger and leaf spring) in 2 separate incidents. The frame appears to have further issues on the passenger side more recently.

The RV has significant frame failure that Grand Design (the manufacturer) is ignoring. I noticed my floors warping and a cabinet crack. There was also some cracking of the fiberglass. I asked the dealership to check it out. The found that the frame is warped, multiple lagbolts are missing and several welds have popped. The RV is unsafe and not road worthy. Grand Design is aware of this issue and has yet to issue a recall or notify owners of the significant structural defect they caused by undersizing the frame and using the wrong lagbolts.
