Deaths

A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year. A further 1 defect investigation is open and unresolved.

This is the year the complaint was filed, not the year the failure happened. The range runs from 2018 to 2026, the last of them a part year, which is why its column is drawn faint.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA has not crash tested the 2019 Grand Design Momentum. Its New Car Assessment Program tests a selection of each year's vehicles and does not reach motorcycles, heavy trucks, motorhomes or most low-volume models, so an absence here says nothing about how the vehicle would perform. It is not a low score.

What owners have reported about this vehicle is below, and it is a different question: a crash test measures what happens to the people inside in a controlled impact, while a complaint records what broke during ordinary use.

An investigation means NHTSA has decided a pattern is worth examining. A preliminary evaluation is often closed with no action; an engineering analysis is the stage that usually precedes a recall.

Frame Flex on Grand Design Fifth Wheel Recreational Trailers

PE24029

Still open preliminary evaluation · opened October 9, 2024

the body 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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

UNKNOWN OR OTHER
I have a 2019 Grand Design Momentum 399TH that has frame flex. We have put in a compliant to Grand Design themselves and had them inspect it. It was confirmed to have had frame flex, twice. The first time it was 'fixed" was April of 2024 at Grand Design Service Center. The second time was November 2025 at Happy Days RV Service Center. During the second time of being "fixed" our exterior drivers side wall had cracks in it as well, they are now refusing to fix the wall stating that because of the tow vehicle we have and the pinbox we currently using. These problems started shortly after purchase when the original pinbox was still there and we had a different tow vehicle. Our Momentum can be

Excessive Frame Flex/Failure& Structure I am reporting multiple serious structural and safety issues with my Grand Design RV that appear consistent with excessive frame flex and failure, as outlined in NHTSA Investigation PE24029.

Large gaps in both the interior and rear toy hauler doors, which compromise insulation and safety concerns. Cracked and misaligned front entry door, even after manufacturer replacement. Generator compartment door fails to lock properly, likely due to excessive frame flex/frame misalignment. Screws popping out of the front cap and a

Frame failure on fifth wheel deck. Noticed when hooking RV to tow vehicle that the pin box would move upward roughly 1 inch. Also when hitched to tow vehicle would notice that all cabinets in front bedroom would move to the point of damaging walls and causing the doors to bind and hit the ceiling. Once I learned of many other Grand Design RV owners having this same problem, I removed the front skin to expose the frame of the rv and found that welds had completely broken, steel angle gussets sheared, along with finding the upper fifth wheel deck welds completely broke free of the upright supports on the passenger side of the rv. With the broken steel and broken welds, the only way the camper

Every Grand Design on this site — 24 vehicles.

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
