The contact owns a 2022 Grand Design Momentum RV. The contact stated while driving at an undisclosed speed, the camper was bouncing up and down. Due to the failure, the furniture detached from the wall. In addition, the bedroom floor fractured and pieces of the floor were separated. The manufacturer was made aware of the failure and the contact was advised to take the camper to a dealer in North Carolina, a six-hour drive away. The dealer determined that the failure was the result of nine lag bolts that were missing from the camper frame. The contact was informed that the failure was due to a manufacturer defect. The camper was repaired; however, the failure reoccurred. The contact stated that the pin box shifted downward, and the main slide on the passenger's side fractured and shifted down towards the ground and the furniture detached away from the wall.

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

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.
