GRAND DESIGN Complaints

Main doors coming open - currently bungee cording , cargo doors coming open - currently bungee cording, slides coming out a couple inches, leaf spring broke during travel on interstate, open case with Grand Design since January 22, 2023, case # 00621051 and Grand Design has not been helpful in addressing these issues. An RV tech confirmed frame flex symptoms: sawdust from nose of rv in interior, furniture rubbing on walls moving bac and forth, broken cabinets coming out of ceiling, missing screws.

After a trip we noticed that when we had the rv connected to the truck, the front closet would not close. There was also cracking on the nose cover of the rv. We (my wife and I) had a problem with the cargo doors and entry doors coming open on other trips and lost stuff on the highway so we talked to the rv dealer to get a frame inspection. what was found was that the frame was broke in a few places and the door side wall of the camper was not attached. We have also had the rear spring hanger break the year before while driving almost pulling me out of the lane I was traveling in. The camper is sitting at the dealers now because it cannot be towed, and the dealer will not weld the frame due to liability. missing and broken bolts in the frame and body were also discovered.

There is a serious electrical issue with the Grand Design Momentum 397ths. There are twenty-three electric outlets throughout the RV. Two are located outside. Two more are dedicated to microwave and electric fireplace. The two for microwave and fireplace are on their own breakers. All other twenty-one outlets are on just ONE 15 amp breaker. Typically there is a maximum of eight outlets per 15 amp breaker or a maximum of 10 amps on one breaker to avoid tripping the breaker. The outlet located on the side of the bathroom vanity under the sink in bathroom located in garage is not a GFCI although labeled as such. There are two GFCI outlets located in the front bathroom and the outlet beside the stove. In April of 2024 Grand Design took the RV from OH to Elkhart IN for repairs and address service bulletins for frame failure. I reported the issue at that time. I was informed the wiring of the outlets are wired according to specs and therefore no changes could be made. There is room for another breaker in the breaker box. We have been living in our RV full time and the breaker has tripped no less than six times per week. This constant overload is only leading to a fire hazards. This is yet another issue and example of potentially life threatening the RV industries refuse to make right.

Excessive front nose cap/upper deck movement during travel (bouncing), suspect welds holding the riser wall and upper deck may be broken. Bottom flange of I-beam buckled over two foot span. Both diver and passenger side walls have pulled away from structural support. Floor dropped on both sides (bowing). Living room floor has slope to the back left since I purchased it new. Kingpin or pin box is not centered and shifted to where philon trim hung up on pin box. Passenger side wall appears to have shifted forward during transport. Bedroom doors no longer align with the jam/catch. Decal on passenger wall where the wall meets the front cap are distorted suggesting frame flex. Grand Design Service Response Team welded an 8 foot bead along the upper I-beam to "adjust" camber however when SRT performed measurements to diagnose he found the passenger side camber to be within spec yet he performed the camber adjustment to this side anyway by welding an 8 foot bead as well. Extended floor joists are bent down. In light of all these issues we feel towing this rig would be a danger to my family's lives as well as any other life on the road around us. Currently the pin box alone has excessive movement.

Frame Failure. 1/24 purchased new, on first trip(~1200mi) door side front cap vertical 1/2” gap between exterior wall and front cap, saw dust and movement at bedroom storage, bathroom door was catching due to movement, dealer repaired 3/21/24-5/17/24. 2nd trip(~2800mi) front cap shows separation, saw dust, filon warping, dealer reports 1/2” movement of pin box, dropped at dealer 11/25/24 as of 2/5/25 still at dealer. Unknown if 5th wheel will separate from pin box while towing on highway causing an accident. Dealer has confirmed excessive movement of the front of the frame twice, the second time after completing manufacture service bulletin.

While we are driving, the front and back door of our rv open while in transit. This happens even when the RV doors are both locked and deadbolted. They both open up and we have had to add a bar to keep the door from opening all the way on the rear, which places us and others in danger while driving. We have pulled over and the door whipped open and hit a road sign, it could as easily hit construction worker. I have reported it to Grand Design, and at that time, it was not repaired. I was at the headquarters at the time. I had already purchased the aftermarket door bar to keep it from flying open, but they both still come unlatched. A dealer has not verified this , and GD does not take it out driving so they would not have verified it either, although they were informed of the issue while I was there for frame reinforcement due to other issues (front landing gear failed due to side to side frame flex) It has not been inspected further to my knowledge. The wall between the main living quarters and the bunkhouse and rear bathroom has movement in transit as well, which is directly by the rear door. There is sawdust still after five years after a move day in the rear bathroom. This leads me to believe there is a lack of structure holding this middle section of the rv together, allowing the shifting while in transit. The doors have opened in transit from the date of purchase, new from a Wyoming Grand Design dealer and has never been properly addressed when brought up. I will say at the time, I was having other major issues fixed, so it was not on the top of my list since I had already bought the door bar to keep it from flying all the way open while driving so I did not push it with GD HQ.

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.

Side front cargo compartments have opened during travel. Left and right side in two seperate incidents. Cargo fell on highway in one incident.

We are experiencing a serious frame issue on our 2021 GD Reflection 367BHS 5th wheel. We normally do not unhitch when overnight boondocking. Last evening we noticed that the floor in front of the bedroom closet seemed to rise up slightly. Didn't think much of it until we noticed at the next campground that the hallway wall by the bedroom door moved up about an inch and the bedroom door was jammed and would not open. Once we unhitched and put the weight on the landing gear the hallway wall moved back into position as did the bedroom floor and the bedroom door was again free to open. After hitching back up, taking the weight off the landing gear, and investigating further, we noticed that the entire frame had separated in the compartment where the propane is on the passenger side of the RV. On a recommendation I was told to check the bolts behind the bedroom dresser that secure the sides to the frame and they were snapped off. Frame flex is a know issue by the manufacture for the past year or so.
