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. We could have crashed putting my family of 4 at high risk as well as others on the road. This was an extremely scary trip with no trailer braking. 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 other wiring. Grand Design told us we were NOT to use our trailer until all fixed. Grand Design flew a technician out 8/20/24 to replace inverter. Technician held up the inverter to us, it was melted. He said this was completely Grand Design’s fault. Also was told by technician to take trailer in for frame flex issues as well from recall by Grand Design. The frame flex was real. We had issues with our slides as well as the body looking crooked on the frame. The RV service center Grand Design sent us to found that there were ZERO lag bolts installed holding the body on the frame. The front corner of trailer was leaking due to the roof failing. Grand Design called for replacement of all cabinetry in front area as well as replace entire roof. This frame flex could have had detrimental outcomes due to the frame not being bolted down. All components that failed have been fixed by a certified rv service center. We have not used the trailer as we picked it up one week ago. We are nervous to use the trailer with all the issues we had. There was no warning to any of these failures.
