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 issue, telling us it had been corrected. The SRT team from grand design welded and added additional lag bolts but did not address the outside cracks on the trailer. Because the trailer was well out of warranty and we were assured that the repairs made were adequate we accepted the fact that we would deal with the superficial flaws on the outside of the trailer. We covered the areas as best we could to prevent any water damage from occurring at those areas. A few months ago we noticed that the cabinets had cracked in a few areas and have continued to separate from the wall also rubbing a hole on the side wall. We returned to Happy Daze who pulled off the front cover and found broken welds and loose bolts on the frame work that was repaired in 2024. Grand design was contacted and has refused to make any additional repairs to make this vehicle road safe currently. We were informed to make a claim with NHTSA regarding this issue.
NHTSA complaint 11761380Based 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 Lippert measuring instructions and confirmed Frame Flex. They are adding gussets and other assorted items to correct this Grand Design manufacturing defect.

The contact stated that the generator doors almost detached, and the front rubber trim hold was detaching. The RV was towed to the dealer, where several repairs were performed; however, the frame continued to fracture. The dealer advised the contact to park the RV. The RV was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was unknown.
NHTSA complaint 11608008This is a 43 foot fifth wheel RV. The frame near the front of the RV is showing signs of "frame-flex," or frame cracking. The attached pictures illustrate where the walls are shifting and creating wear marks; this is consistent with other RV owners experiences the same problem. This issue could contribute in further frame cracking that may result in significant property damage or even death. I plan to report this issue today to the manufacturer, Grand Design.

NHTSA complaint 11355172THE BRAKE ASSEMBLIES MANUFACTURED BY LIPPERT COMPONENTS INC ON THIS RV AND MANY OTHER RV'S HAVE AN ISSUE KNOWN BY THE MAUFACTURER RELATED TO AXLE GREASE LEAKING PAST THE INNER LIP SEAL. THE EXCESS LEAKING GREASE CONTAMINATES THE BRAKE PAD AND DRUM CONTACT SURFACES RESULTING IN SEVERLY DIMINISHED BRAKING ABILITY, WHICH COULD LEAD TO AN ACCIDENT IN EMERGENCY STOPPING SITUATIONS.

NHTSA complaint 11115609I PURCHASED A NEW GRAND DESIGN MOMENTUM 350M AT HOLIDAY WORLD KATY, TEXAS. AFTER TAKING DELIVERY OF THE CAMPING TRAILER & CHECKING HOOK-UP TO TRUCK, LIGHTS & BRAKES IN THE PARKING LOT, I TOWED THE 350M ABOUT 50 MILES ACROSS HOUSTON. I WAS QUITE CONCERNED WITH THE POOR BRAKING QUALITY OF THE CAMPING TRAILER, EVEN AFTER INCREASING THE TRUCK BRAKE CONTROLLER GAIN TO 9.5 (OF POSSIBLE 10). I THOUGHT MAYBE THE BRAKES NEEDED MORE 'BREAK-IN TIME' SO A COUPLE OF DAYS LATER I SLOWLY TOWED THE CAMPING TRAILER 400 MILES TO MY HOME IN S. TEXAS. I BECAME VERY CONCERNED WITH THE BRAKING QUALITY OF THE 350M AND CONSIDERED IT A SERIOUS SAFETY ISSUE. ONCE HOME, I WOULD NOT TOW THE UNIT ANY FURTHER WITHOUT MAKING SERIOUS IMPROVEMENT TO THE TRAILERS BRAKING CAPABILITY. AFTER JOINING GRAND DESIGN OWNER FORUMS WE REALIZED THAT MANY OTHER OWNERS ALSO HAD BRAKING ISSUES. I HAD A CERTIFIED MECHANIC PULL WHEELS & HUBS. LIKE MANY OTHER OWNERS, ALL 4 ELECTRIC/MAGNETIC BRAKES (DRUMS, MAGNETS, SHOES & ALL INSIDE THE DRUMS) WERE COATED WITH A HEAVY FILM OF GREASE. UNDERSTANDABLE WHY THE 350M & LIPPERT'S SELF ADJUSTING, ELECTRIC, MAGNETIC BRAKE SYSTEM WAS EXHIBITING VERY POOR QUALITY, UNSAFE BRAKING CAPABILITY. LIPPERT (LCI) SEMI-ADDRESSED THIS ISSUE IN JANUARY 2017 BUT WOULD NOT ADMIT ANY FAULT ON THEIR BEHALF. THERE IS OBVIOUSLY A PROBLEM WITH THEIR BRAKE SYSTEM THAT NEEDS ATTENTION FROM THE NHTSA BEFORE THERE IS A SERIOUS ACCIDENT. ATTACHED IS A PICTURE SHOWING SOME OF THE GREASE CONTAMINATION UPON REMOVING THE WHEEL HUB FROM THE AXLE. THESE BRAKES DEPEND ON THE MAGNETIC FORCE AGAINST THE ROTATING HUB TO 'APPLY BRAKE SHOE PRESSURE TO THE DRUM'. UNDERSTANDABLE WHY THE BRAKES DO NOT WORK EFFECTIVELY WITH A GREASE FILM ON THE MAGNET, ALL INSIDE THE DRUM AREA & ALSO ON BRAKE SHOES. SHAMEFUL WHY A LARGE COMPANY LIKE LIPPERT WILL NOT "OWN UP" TO & CORRECT THE PROBLEM ! CAN THE NHTSA HELP ?
NHTSA complaint 11000307LEAKING GREASE SEALS ON 5 OF 6 WHEELS; 6TH GREASE SEAL SHOWED SIGNS OF FAILURE.
NHTSA complaint 10992601THE WIRING FOR THE ELECTRIC TRAILER BRAKES ARE NOT IN ANY PROTECTIVE COVER AND ARE IN DIRECT CONTACT WITH THE SUSPENSION, FREE TO MOVE AND CHAFE. WHEN ANY OF THE 12 VOLT POWER WIRES RUBS THROUGH AND THE BRAKES ARE APPLIED IT WILL CREATE A DEAD SHORT, BLOWING THE FUSE IN THE TOW VEHICLE AND LEAVING THE DRIVER WITH A 15,500 POUND TRAILER WITH NO BRAKES TO AID IN STOPPING. THE ATTACHED PICTURES ARE OF THE DRIVERS SIDE.
NHTSA complaint 10971735THE CURB SIDE ELECTRIC DRUM BRAKES ON BOTH AXLES OF OUR TANDEM AXLE FIFTH WHEEL RV ARE GREASED AND HAVE FAILED. THE ROOT CAUSE SEEMS TO BE THE FAILURE OF THE DOUBLE LIP INNER GREASE SEAL. IT ALLOWS GREASE INTO THE BRAKE ASSEMBLY WHERE IT IS FLUNG ABOUT SATURATING THE SHOES AND SPLATTERING ON FRICTION SURFACES. THE ATTACHED PICTURES SHOW THE SHOES AND ELECTROMAGNETS ARE COVERED IN GREASE AS IS THE WHEEL HUB, ARMATURE AND MISCELLANEOUS BRAKE COMPONENTS. THE RESULT WAS NEAR TOTAL LOSS OF TRAILER BRAKING ON THAT SIDE OF THE RV PLACING OUR LIVES AND THAT OF OTHERS IN DANGER IN BOTH HIGHWAY AND URBAN DRIVING. BOTH ELECTROMAGNETS ON THE CURB SIDE FELL OUT OF THEIR RESPECTIVE ASSEMBLIES WHEN THE HUBS WERE PULLED SUGGESTING THE RETAINERS HAD EITHER BEEN LEFT OFF OR HAD FALLEN OUT AT SOME POINT. NO RETAINERS WERE RECOVERED. IN GENERAL DRIVING AND BRAKING SCENARIOS IN THE CITY AND ON HIGHWAYS, WE HAVE EXPERIENCED SIGNIFICANT LACK OF ASSISTIVE BRAKING FROM THE RV TRAILER. IN REMOVING THE FACTORY BRAKE HUBS RECENTLY, WE DISCOVERED GREASE ALL OVER TWO OF THE FOUR BRAKE ASSEMBLIES. THIS FAILURE IS COMMON ACROSS THE RV INDUSTRY ACCORDING TO THE OWNER'S FORUMS. A POLL ON THE GRAND DESIGN OWNER'S FORUM LISTS 136 OWNERS AT THE TIME OF THIS WRITING THAT HAVE HAVE HAD SOME OR ALL OF THEIR FACTORY BRAKES FAIL DUE TO INNER GREASE SEAL FAILURES. HTTP://WWW.GRANDDESIGNOWNERS.COM/FORUM/SHOWTHREAD.PHP/8531-POLL-HOW-MANY-OF-YOU-HAVE-HAD-YOUR-GREASE-SEALS-FAIL?P=104366#POST104366 SINCE THIS FAILURE IS HIDDEN FROM VIEW, WE CANNOT BE PRECISE AS TO WHEN THE FAILURES OCCURRED. OUR SEALS FAILED SOMETIME BETWEEN DELIVERY FROM THE FACTORY TO THE DEALER IN EARLY MAY 2016 TO MARCH 19TH OF 2017 WHEN WE PUT OUR RV IN STORAGE. WE HAVE DRIVEN IT ABOUT 5000 MILES OVER THAT TIME. THE FAILED BRAKE HUBS WERE PULLED BETWEEN MARCH 25 AND MARCH 26TH.
NHTSA complaint 10969127A KNOWN PROBLEM ON MANY GRAND DESIGN UNITS, TOLD BY BOTH THE MANUFACTURER AND THE DEALER THAT PROBLEM HAS BEEN FIXED, AND THAT UPON DELIVERY, THE BRAKES ON MY NEW UNIT, DELIVERED ON 09/23/16, WERE CHECKED OUT, AND GREASE FREE. UPON ARRIVING AT MY HOME, ONE WEEK LATER, BRAKES ARE COVERED WITH GREASE AND MY RV SERVICE REPAIR CENTER SAID THE UNIT NEVER SHOULD HAVE BEEN DRIVEN AS IT IS UNSAFE. I AWAIT GRAND DESIGN'S RESPONSE, PHOTOS HAVE BEEN TAKEN, BUT AFTER REVIEWING ALL THE GREASED BRAKE COMPLAINTS ON THE GRAND DESIGN OWNERS FORUM, I DECIDED THIS PROBLEM IS LIFE THREATENING TO ALL OWNERS, NEW AND OLD, OF GRAND DESIGN RV'S, AND ALL SHOULD BE RECALLED.
