2020 GRAND DESIGN MOMENTUM Complaints

We noticed our pin box on our GD started moving when we hitch up. The wall inside the bedroom is showing wear from movement, the trim around the upper deck came apart multiple times, the flooring inside the bedroom had a hole in it from the bed gouging into it. When hitching up the wall is bulging out on driver side just off of the slide corner. Our slide stopped working and there are Gibs inside the wall of the slide that had sheared off rivets.

I have had front flex on my grand design repaired twice already and it’s still has issues. They didn’t weld any of the aluminum back together they would only do the frame, my bedroom walls and cabinets wouldnt get fixed either because that’s cosmetic.

We are experiencing frame damage on our Fifth wheel portion of the RV! The welds are cracking, and causing the front of the RV to shift and sag when hitched to the truck! We reached out to the manufacturer for help and they confirmed that we do have what they call "Frame Flex" They consider this a warranty item and we are out of warranty so we are on the hook for a $16000 plus repair bill! We have been in contact with 100's of others who have had this issue, sometimes the frame is repaired by the manufacture under warranty, and other times they get the insurance to pay for the repair! We have been contacted by several individuals who want to pursue a class action lawsuit over this matter! We feel that you should step in and determine if they are selling the correct frame that is fit for the RV they are building and allowing us to drive on the roads in the USA. Since this is not an isolated event there are so many of these RV's on the road with frames that are not built to properly hold the GVWR of the RV! These RV's are currently being towed down the highways and if a complete failure happens while towing the RV could buckle and fall apart on the road! We fell you should investigate and determine if the Manufacturer is in fact using a DOT approved frame for the RV's they are selling! If they are not a recall should be issues and all of the owners should have their units fixed to make the safe for use on the highway!

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.

The front area where the pin box connects to the truck has multiple welds are breaking on the structural frame causing these trailers over flex while driving down road. There has been multiple cases of the front deflection being out of spec on multiple trailer. With these welds broken it can cause the trailer to separate where the truck would hook up to the trailer and if the concern is not addressed.

We used the gas water heater on our Rig. Come to find out, it blew the cover off the water heater, burned the wires and melted the case. We are very lucky our rig did not catch fire.

The contact owns a 2020 Grand Design Recreational Momentum. The contact stated that the floor was started buckling and there were bubbles on the flooring of the trailer. The contact stated that one of the bubble was near the front bedroom towards the bathroom, and the other bubble was towards the hallway. The contact took the vehicle to the local dealer however, the mechanic was unable to identify the cause of the failure however, the mechanic was willing to fix the esthetics by sanding the floors and replacing the linoleum. The trailer was repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 1,000.
