2022 Grand Design Momentum

BOTH ACCESS doors are opening in transit along with pass thru baggage storage doors this has been brought to the attention of the manufacturer and the selling dealership We have had to tape the doors shut just to get somewhere safe These problems started shortly after purchasing its been back to the factory for repairs where they found abnormal frame flex / failure ,we were told additional frame gussets were added There was stress cracks in the front cap area which we found out later that is a sign of abnormal frame flex which we believe is causing the doors to open allowing items to eject onto the roadway

Frame not strong enough to support full GVWR. Result. Frame flexing excessively which can lead to frame failure and separation from the vehicle on the highway endangering everyone. Manufacturer has done their recommended fix on my rv but they have a history of ineffective repairs. So far my rv hasn’t been on the road enough since first repair to know if it will hold.

A spring snapped in two near the mounting point to the frame. Rv was not overloaded. Grand design authorized replacement of all springs which is now complete. Others have had similar failures. Im guessing the metal used was too brittle. The busted spring can cause the rv to pull sideways a bit making safe controlling on the highway a possible hazard to everyone on the highway. An accident could occur endangering everyone around the rv with failed suspension. I managed to catch the failure before any injuries occured.

I was towing my 5th wheel RV when I noticed doors I locked were swinging open. I noticed the rear toy hauler door first. The plastic screen door cover was missing and was unable to be found. A few miles later I noticed the front underbelly storage area on the passenger side was swinging open. Some power tools fell out and were unable to be found. A few hundred miles later the propane door unlatched and was swinging open. I closed and proceeded on route. My Lippert frame is flexing causing these locked doors to open mid travel, losing personal belonging in the middle of the interstate. Later that trip I noticed my front bedroom slide-out was moving out on one side (driver) After pulling over and attempting to pull it in, the slide would not pull in. It was sticking out about 8" off the side of the walls of the RV. Lastly I noticed my pin box was at a hard angle when traveling. It appears that something on the frame to the pin box is not secure. The RV needs to be inspected by the manufacturer as soon as possible to prevent major casualty.

We live and travel full time in a 2022 Grand Design Momentum model 376THS. Screws and bolts holding the front opposing schwintek slides are breaking or backing out of the slide frame every time we travel, the front floors are squeaking and getting worse, the front cap developed stress cracks and was repaired one year ago - they have now reappeared and there are several more stress cracks visible on the front cap, the front side storage doors are coming OPEN DURING travel, we have lost items on the road from these areas, they are always locked closed before we travel. I believe this maybe be caused by a flexing coach frame.

Upper deck failure ( side pod door opens when in transit, front of trailer at king pin mounting flexing when in transit, king pin mounting hits truck bed rails when turning, bedroom floor buckling, bed rollers leave indentations in bedroom floor closet door not plumb and will not lock when disconnected from truck, front wall height changes when connected to truck, trim and panels coming loose in transit. ). Wall to frame mounting has loose, missing and wrong size lag bolts. Inspection is available upon request. Door popping open in transit is a safety hazard for myself and everyone on the road. The vehicle has been to two different dealerships and the representatives at both mentioned frame issues as part of the problem. The first issues were noted at 2,000 miles on 9-19-2021

I am experiencing what I believe to be a frame issue. When I take the weight of the 5th wheel off the landing gear and transfer to the 5th wheel pin I see lots of movement and hear a lot of popping and cracking noise. My floor above the 5th wheel hitch is now squeaking badly and there is a nail that has pushed through the flooring. I have broken screw in my slide out and the sealant is showing signs of movement. The trim cover sealant is pulling away so I believe the whole front of my 5th wheel is moving. My concern is this is getting to the point it maybe unsafe to pull down the highway. This appears to be a rising concern with Grand Design and Lipert frames as there is now a TSB sent out for inspection instructions.

Frame flex causing other issues. broken wet bolts, slide operation, awning hanging up, wall seperation, screws coming up through the floor, storage door popping open going down the road. RV was evaluated by a Grand Design SRT and returned to Grand Design service center for repair in December 2023. Traded unit for a new RV in Florida in March 2024.

The contact owns a 2022 Grand Design Momentum. The contact stated that the RV was purchased brand new and taken to the residence, where the contact noticed that the front driver's side nose had detached at the fifth wheel pin location. The RV was taken to the dealer, where it was repaired; however, the failure recurred while the RV was still at the dealer. The RV was repaired. Additionally, the contact stated that the sliding doors were not opening and closing properly due to the frame flexing. The contact stated that the suspension was fractured and was making abnormal popping and creaking sounds. The contact stated that the washing machine was leaking water. The contact also stated that there was excessive propane consumption. The dealer determined that the propane was leaking through the rear of the refrigerator and another point of leak was identified. The contact later received an email from the Grand Design RV CEO advising that the frame warranty had been extended to 5 years. The contact stated that the Extended Warranty repairs included installing braces, bolts, and welding the frame. The RV was not repaired. The manufacturer was not notified of the failure. The failure mileage was 700.
