Owner report 11633961 · 2025-01-03 (January 3, 2025)
We are showing many signs of excessive frame flex/failure in our 2023 Grand Design Momentum 397THS. Our baggage/storage doors do not properly fit nor lock. The RV was in the shop from Jan-May 2023 to address this. Had the doors replaced and resealed. They still are not flush with the RV, still barely latch, and have popped open while driving. While in the shop, they addressed but "could not duplicate" the underbelly continuously filling with water when it rains. Excessive amounts of water that saturate all of the insulation-- causing us to dr…

Owner report 11639169 · 2025-01-28 (January 28, 2025)
We were driving through a mountain range and the trailer brakes went out on Trailer. Had to us exhaust brake to slow trailer down and stop.

Our inverter and battery switch caught fire during a camping trip 8/12/24. My family was put in harm's way with the possibility of the trailer going up in flames! Called Grand Design. They immediately made a ticket for a technician to come replace inverter and o…

Owner report 11627101 · 2024-11-24 (November 24, 2024)
My RV's frame has compromised integrity. During transit, it flexes beyond the allowable range specified by the manufacturer. The inspected frame is available for further evaluation upon request. The flexing of the frame poses a significant safety risk, resulting in cargo doors opening unintentionally and RV slide rooms shifting to the open position while the vehicle is in tow. Furthermore, during my inspection and the subsequent assessment by the authorized service center, I identified multiple critical issues: lag bolts connecting the unit's …
