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 2016 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 2017 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
In early 2024 we noticed a binding on the bedroom slide, we took it in for service at Happy Daze in Ripon and the repair shop fixed the slide issue. After our next camping trip a month or so after the repair, we noticed a crack on the outside driver side of the front of the trailer above and below the bedroom slide. We had noticed a gap in the front bedroom cabinets in which we had attributed to normal wear and tear and had reinforced with screws and wood trim previously. In contacting Happy Daze again we brought it in for the new issue and realized that we were experiencing frame flex/failure. Happy Daze connected with Grand Design who sent a team out and did a goodwill repair of the

Based on internet craze of and symptoms of Frame Flex | Frame Failure on Grand Design Momentum 5th wheels I had my unit measured for Fram Flex by Grand Design at the GD East Coast Rally. According to their measurements at that time I was 1/16 inch away from needing to be concerned regarding frame flex. After the fact in reading Lippert Components Incorporated (LCI) measuring instructions Grand Design did NOT measure my unit per LCI's instructions. After much thought and continued symptoms of frame flex we decided to incur personal expenses and took our unit to Affinity RV group of Goshen Indiana to have an independent frame inspection completed. Affinity RV measured our unit following

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.
