2015 Grand Design Momentum

Potential frame failure. First noticed [XXX]. Grand Design contacted, but no appointment due to "Customer Care Center" being moved. Referred to Royal RV in Middlebury, IN. Appt. set for Mid May. No concern by GD that we would be traveling 1500 miles. Visual inspection @ Royal RV suggested potential frame failure. Appt. set for June 18th for full inspection. Both Grand Design {case# XXX} and Lippert Components {case# XXX) where notified of the situation and offered opportunity to visit Royal RV while the RV was there. During the time before returning to Royal RV a YouTube video was discovered showing the same RV as ours with the exact same issues had been shared with GD on March 28th, 2018. RV returned to Royal RV XXX, 2022. Their inspection identified broken welds same area as shown on the above mentioned video. After much effort, Lippert arrived XXX 2022 to make repairs. Lippert Tech noted that delamination under bedroom slide was most likely caused by broken welds but he could not correct. Contacted Grand Design but could not schedule an appointment due to "rally appointments". Appointment set for our return in May, 2023. No concern by Grand Design on our 3000 mile round trip. RV returned to Grand Design on XXX, 2023. Very little detail on what corrective action taken other than to repeat "your frame flex" problem corrected. Much more detail on the bedroom slide issue. A section of the outside wall removed as well as the complete slide to repair broken welds. We picked up RV approx. on XXX. Reviewed Work Order #XXXXX. Again no details on the frame failure only the Flex Issue. Spoke with the Customer Care mgr. to relay our disappointment with Grand Design and Lippert to feel no responsibility for endangering lives on the highway. Out of pocket expense for us $3821.00. Our ins. company, National General, denied our claim (claim# XXX) due to their determination the failure was a mfg. defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Mounting bolts from frame to Rv front sidewall are in 3/8” lag bolt mounted in pine wood (all are striped, won’t tighten). This allows the complete front Rv wall to move allowing further frame issues. Holes in frame rail are 1/2” , grand design installed smaller lag bolts 3/8” this has caused the bolts to eventually fail. This is happening on approximately 30% or more of Grand Design RVs. The factory needs to provide a recall on this problem.
