2023 Grand Design Momentum Other or unknown Problems

“Overview: This complaint is being submitted in response to alarming and persistent structural failures experienced in our 2023 Grand Design Momentum fifth wheel RV, purchased new in January 2023 from Lazydays RV in Tampa, FL. Despite receiving a factory service bulletin (TSB) and subsequent repairs under warranty, our unit has continued to exhibit excessive frame flex, wall and floor deformation, compromised slide operations, and related structural issues. …”

“We have a brand new 2023 Grand Design Momentum 5th wheel. Had her for 9 months. Taken only 2 trips thus far. I have a structural stress fractures on the corner of my closet slide (approx 4”), caulking around the front cap has been pulled away, both sides of our bedroom upper cabinets have about 3” cracks on the bottom along the wall from frame flex / failure. It’s difficult to close our main door. Often times it requires us to slam once or twice to get the door to close. All this is due to frame flex. …”

“In 2023 we purchased this RV. Recently, we discovered that the cargo carrying capacity is incorrect by about 900 pounds, subject to Recall 23V-428. Grand Design knew of this defect before the rig was sold; however, they didn’t remove the vehicle from the dealers lot, nor were we ever contacted by Grand Design. Grand Design knew of the issue in June 2023, and we purchased our rig in July 2023. We also have had the rig in for repairs for broken leaf spring supports and now they’ve done some welding on our frame because of frame flex issues.”

“The dealership has declared frame failure and failure of the pin box flexing up to 3-4 inches just picking it up with a forklift. Lag bolts are missing and/or backed out. Dealer has deemed it not safe for use. They will not move it out of their bay. Fist signs were wall separation throughout the RV. Doors not closing because door opening was out of square. Floor squeaking in multiple location. Center Island moves and squeaking. Abnormal wear on middle axle tires. Unusual pop from passenger level leg that shakes the rig. Excessive creaking underway.”

“Purchased new June 2023 in Tuscon AZ. No issues until underbelly filled with water and had to be serviced in Albuquerque NM. Issue was not resolved with water pump replacement. Towed to Homerville OH not knowing water leak still exists and where frame flex was discovered. Man doors, propane tank doors, and basement doors randomly open while in tow and stationery. The seal for nose cone and felon broken and screws missing that secure nose to the chasse. May 2024, Grand Design picked up and towed the 5th wheel back to factory for frame flex repairs. …”
