2022 GRAND DESIGN MOMENTUM Unknown Or Other Problems

The issue with the frame having issues causing a safety concern and interior damages. When the frame over flexes it will stress other components, walls, trim, and cabinets.

DUE TO EXTREME FRAME FLEX, THE WELDS IN THE FRONT OF MY COACH BROKE AWAY FROM THE METAL. MY UNDERSTANDING IS THAT THE ONLY THING HOLDING MY 44' TOY HAULER ON MY TRUCK WAS THE INTERIOR AND EXTERIOR SKIN OF THE COACH. I WAS HORRIFIED TO FIND THAT I WAS DRIVING MY COACH UNDER THESE DANGEROUS CONDITIONS CAUSING EXTREME RISK TO MY FAMILY AND THOSE ON THE ROAD. TO BE CLEAR, THIS FAILURE ONLY SHOWED ITSELF WITH ONLY MINOR SYMPTOMS TO AN UNTRAINED EYE. AFTER READING ALL THE COMMENTS ONLINE, I REALIZED THIS NEEDS TO BE ADDRESSED FOR EVERYONE CONCERNED

Our 2022 395ms is being taken back to the factory in Elkhart Indiana due to unsafe frame flex/failure

FRAME & STRUCTURE FAILURE What component or system failed or malfunctioned, and is it available for inspection upon request? Frame failure - yes, it is available How was your safety or the safety of others put at risk? Structure failure during transport would cause obvious harm and possibly deaths Has the problem been reproduced or confirmed by a dealer or independent service center? No, this is our first step Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not since the issue occurred. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. Current symptoms are: Huge gap in filon (1 inch or greater) by pin box, sawdust and trim falling off in bedroom closet, doors opening during travel - pantry door, refrigerator door, laundry door in bedroom.

Fiberglass separated, storage doors bowed, Movement in pinbox, broken frame, inside wall movement, trim wearing with movement

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.

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.

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.

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.

Frame flex issue outside spec dealer said they fixed it but it comes back.

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.

Bolts going thru frame to exterior walls were broken, missing and or loose. While driving down the road the whole front of our trailer was loose and made our tow vehicle feel like it was not in control at some points. The problem started sometime around March or April of 2023 we think. We reported it in May 2023 and took it to the dealer in June 2023. At that time we were told they tightened up the bolts and we were safe for travels. We took it back to the dealer in July of 2023 and still the same comments from the dealer and nothing from the manufacturer. Finally in November 2023 we had had enough and between being in front of the dealer and calling the manufacturer it went back to the shop in January of 2024 to get fixed. After lots of research and talking to fellow Grand Design owners this appears to be a regular occurring issue and the manufacturer has not done anything to make good on it unless you fuss a little bit. The main issue is the bolts going thru the frame into the walls are to small. Putting 3/8” bolts in an 1/2” hole and they were about a 1/2” short into the wall with no type of fasteners or something to hold them in place or keep them from loosing up. When they made the repairs they put in 1/2” bolts and added some cyberbond to hold them in place and then added a thru bolt in the frame close the the end of the wall under the cap.

Frame started to flex excessively in the king-pin area and on the inside, above the king-pin area. Issue was confirmed by independent RV dealer. The movement exceeded Lipperts stated limits for the frame to flex. After consulting with Grand Design and Lippert, instructed to take RV to local Grand Design dealer for further inspection and repair. Dealer found broken welds on the frame, broken bolts attaching side wall to frame, and missing bolts intended to attach wall to frame. After authorization by Grand Design and Lippert, Lippert send repair tech Onsight to repair. Broken welds were repaired with additional steel added to frame and missing/broken bolts replaced.
