We are victims of frame failure. First sign was a creaky floor in the bedroom. Screws worked their way out of the wood flooring and pushed up underneath the linoleum. The movement of the nose cap pushed screws out of the trim and seal piece on the underside of the front cap. We reseated screws, upgraded screws, resealed this at least 5 times and now use gorilla tape to avoid water intrusion. The underbelly has fallen down while traveling so we had to reinforce this ourselves. Our driver side bay door will fly open when traveling. It locks but the locks will not hold it closed when the rig starts to flex. We now gorilla tape the door every time we travel to avoid objects flying out of our bay into traffic. The partition between the wet bay and the storage bay has bent. Our front driver side jack is not straight, it points outward. There is rubbing of the shelving and trim in the bedroom. The board that has the slide rollers under the main bed has failed. We have pinched decals on the exterior of the nose cap. The pin box sinks up into nose cap when hitched up. We have a toy hauler however we do not haul any vehicles or toys in our rig. We have had to replace both back leaf springs due to them failing. The main lighting panel has been damaged in transit so that the exterior accent lights will no longer turn off. This is an electrical hazard as well as an annoyance to anyone that camps near us. The roof seal that attaches the roof membrane to the front cap is elevated and not flush. When traveling from TX to Indiana for our frame failure appointment, the roof membrane completely shredded and fell back over the air conditioner. We had to gorilla tape the remaining roof to make it the rest of the way. Grand Design is not issuing a recall yet. Our rig is dangerous for us and anyone on the road with us. Our rig is in the shop right now and we have the highest hopes that it is properly fixed, and we do not have to return like so many others are.

PE24029 · Frame Flex On Grand Design Fifth Wheel Recreational Trailers

Opened Oct 9, 2024 · No close date supplied

Status: open (inferred from source dates) · Structure

The Office of Defects Investigation (ODI) has received twenty-three complaints alleging excessive frame flex on model year 2017-2023 Grand Design fifth wheel recreational trailers, models Momentum and Solitude. Twenty-two of the complaints allege that excessive frame flex resulted in a cargo or entry door opening while in transit, some with objects lost on roadways, while six complaints also state that slideouts extended out partially. ODI has been in contact with both Grand Design and Lippert, the frame manufacturer. Grand Design believes that some frame flex, generally considered to be vertical movement in the upper deck area of the fifth wheel, is normal. However, Grand Design has developed a technical service bulletin (TSB), to evaluate concerns of excessive frame flex, defined as vertical movement greater than 3/8 inch. Per Grand Design, the frame flex is only occurring in the upper deck area of the fifth wheel and is resulting in cosmetic defects such as moving sidewalls, damage to cabinets, binding doors, etc. However, Lippert believes that the effects of frame flex may also extend back to the front axle of the trailer.While Lippert provides frames for multiple trailer manufacturers, the majority of complaints are for these Grand Design products. Cargo and entry doors that open and slideouts that extend while in transit increase the risk of injury or a crash. ODI is opening this Preliminary Evaluation (PE) to evaluate the severity of the potential problem and to determine whether an unreasonable risk to motor vehicle safety exists.
