NHTSA Complaint #11641738 — 2021 GRAND DESIGN MOMENTUM

We started noticing issues on our RV and reported it to Grand Design. Those issues included bolts holding front philon breaking and loosening, wallpaper at base near floor shifting, excessive new noises on slide movement, lippert legs stopping due to being off balance on level ground, stress cracks in front cap, sawdust in pantry cabinet, loose lag bolts upon further inspection and dresser panel repeatedly popping off on travel days. Based on the issues, we took it to a a GD dealer (La Mesa in Sanford FL) for inspection. After measurements I was told by Grand Design that it was excessive frame flex. The philon was removed by the dealer and in that small section no obvious cracks were noted. They replaced lag bolts from the inside. We asked if they would remeasure and they said that Grand Design didn't require that, but they would. We were told that the measurements did not change after the lag bolts were replaced. They did not fill out the official form since Grand Design didn't require it. They repaired the stress cracks in the paint, but the dealer told me that the wallpaper shifting and sawdust was normal. We took the vehicle and then the caulking all cracked where the philon attached (the same places that bolts broke and were loose prior to. I am concerned that there was not further inspection, so I called Grand Design. They said the measurements are in spec and always have been, so he's not sure why anything was done. From my research and from looking at the forms, 1/2 inch is out of spec and nothing has changed on my rv.
