We have signs of excessive frame flex in a Grand Design Reflection RV. We have allowed them 2x to inspect and they have botched both inspections. We keep being told there is no TSB or frame flex in reflections, which is not accurate as there are owners who have had cracked welds and major frame failure in reflections units. Grand Design needs to step up and support all customers not just momentum and solitudes because they are under investigation. I urge the NHTSA to expand their investigation to all Grand Design Models. Here is the list of signs of upper desk frame flex we have in our unit: 1. Lag bolts were backing out in bedroom (these have been replaced during the 2 botched inspections) 2. Graphics slightly bunching near trim 3. Screws backing out that hold on philon trim (we have been having to keep tightening them). 4. Philon trim had shifted significantly since it was just replaced (after 1 hr drive home from shop where my husband confirmed there were not gaps). 5. We also do have some noise hitching and unhitching like a creaking. We had 1st inspection in early 2024. It was botched. GD dealer did not follow procedures. We had 2nd late 2024. This too was botched. We have requested a GD SRT be sent to do a proper inspection and repair with us being able to observe the inspection. This request still unresolved going on a month. We have had our main door fixed multiple times because it ds not close properly (could result in door opening while in motion). This could be due to frame flexing. We had a major issue on a trip in Nov 2023 in which both of our axles bent and we almost blew our 2 tires. This could have been catastrophic and we believe this may be due to under designed components or frame flexing. We also have frame cracks (at least one on each side of the ibeam main frame) that have been confirmed and are scheduled for repair 1/22/25. 1. Frame — yes 2. See above 3. See above 4. See above 5.
