The contact owns a 2020 Grand Design Momentum RV. The contact stated that while in the process of lubricating the wet bolts of the RV, the contact noticed that the rear-most bolts were missing, and the springs were rubbing against the frame. The mobile technician performed a temporary repair at the residence. The RV was then towed to the dealer, where it was diagnosed. The dealer determined that the spring brackets needed to be straightened and reinforced and needed to be welded inside the brackets. The wet bolts and axle U-bolts and attachments needed to be replaced, the passenger's side and driver's side rear-most tires needed to be replaced. The dealer filed a warranty claim with the manufacturer; however, the claim was denied because the suspension was not covered under the frame warranty coverage. The contact related the failure to NHTSA Action Number: PE24029 (Structure). The failure mileage was approximately 10,000.

Issues with: - original drum breaks failed due to incorrect wiring, requiring 100% assembly replacement. - front wall separation - trim and cabinets moving and separating from walls - missing and broken lag bolts - front weather stripping separated from front cap - excessive sawdust under cabinets after any travel - wallpaper wear showing excessive movement of front bed overhead cabinets during travel - floor joists separating from upper floor - slides opening during travel - leaf spring hangers bending and twisting, and breaking off - spare tire mount failed during highway travel, and spare tire fell off on highway - contacted manufacturer to report in 2024 and they indicated we should self-replace the missing and damaged lag bolts with larger 1/2 inch ones. This was done, and they continue to back out on every trip whether 5 miles or 500 miles.

I was informed that I have a broken frame upfront in the Kingpin area. I sent this to Grand Design and they denied any responsibility Grand Design Please find attached the pictures that were taken today (will Attach when sending final) and an email below to Blue Dog RV in Pasco show that I was very concerned about the front cabinets rubbing and asked to have them follow up with you. As you can see that email is dated Sept 7 2022 and is clearly still within the Warranty period for this frame problem. I have tried numerous times calling Blue Dog and left messages but no return calls. I had given them my cell number to call since I was traveling out of state. I did call Grand Design and complained that the Dealer network that they have is terrible and how am I supposed to get things fixed and the nice lady told me to go ahead and find a “local little dealer”. I was able to get it into A’s Parts & Repair that was booked out until June. A's Parts & Repair looked in to it and found the King Pin box has over an 1” of movement and then I was contacted by A's Parts & Repair asking to pull the front lower section by king pin box then to have Micah's custom works to evaluate the damage & then Micah took a look at it said the frame has multiple brakes & not sure how to brace the frame & declined to even attempt it & recommend to return for repair or replacing frame for the toy hauler back to the factory. Manufacturer Broken welds and under reinforced thus causing the cabinet issues. I have included the updated pics of the welds and they feel the whole front cap is moving and their local welding specialist says he cannot fix it due to the extent of the failures. The frame up front in the King Pin area is broken and have broken welds due to flaw in design. I contacted my ins company and Progressive Ins denied claim and states that it is clearly a manufacture design flaw .

BROKEN WELDS IN THE FRAME IN 5 DIFFERENT PLACES. The dealership in Grand Junction Colorado has told us the rig is to unsafe to tow it off their lot. The dealership in Grand Junction Colorado are the ones that diagnosed the broken welds in the frame. The RV has not been inspected by the manufacturer. Manufacturer has only asked more questions and asked for additional photos. We walked into the RV and noticed that the cabinets had moved and the trim was hanging down. We first noticed this on June 5th. Called the dealership on June 7th to make an appointment to have them inspect it. The appointment was made for June 16th. That is when they told us we couldn't use it.
