Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists.

The front left slide stopped working 3 weeks ago. Something appeared to be wrong with the wall but I was not sure. Yesterday I noticed the front left portion of the frame was flexing a significant amount. I started inspecting the frame and I am seeing broken welds

What component or system failed or malfunctioned, and is it available for inspection upon request? - The frame is failing. It is available to be inspected but must be inspected on site. The camper is no longer safe to drive. After we heard a loud pop when attaching to the truck and seeing the pinbox move into the nose of the camper, we don't feel comfortable moving it. How was your safety or the safety of others put at risk? After speaking to others who have this same problem, there's the possibilities ranging from exterior doors flying open during transit (stuff in our basement coming out and hitting other vehicles) to causing a major (possibly fatal) accident if the welding to the pinbox completely fails. Has the problem been reproduced or confirmed by a dealer or independent service center? No, they refuse to send a service technician to my location. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? These symptoms have shown since we bought the camper in March 2024, but we didn't know that they were symptoms of frame failure. - The exterior doors do not close properly anymore and don't seal properly. - The weather stripping on the sides of the filon fell out during transit and were loose in the wind. - A visible flex on the driver's side where the nose connects with the rest of the rig - Screws working themselves out - The pinbox is going inside the nose of the camper when attaching to the truck We've been in contact with Grand Design about this issue. Though we've stated that this camper is no longer safe to drive and have sent sufficient evidence of this issue they refuse to send a technician to my campsite to reinforce and transport this camper for repair. I have no safe way of transporting this rig to a dealership, but they insist that I drive it to be inspected.

after pulling the camper home from a trip, we noticed that the molding was separating from the frame, after further inspection, we found that a weld was broken up on the frame that you can view from the front propane storage compartment. We contacted Grand Design and Lippert, we were told from Lippert to contact GD, we did that and GD has scheduled an SRT team to inspect our unit at the end of September. IN the meantime, we had a certified welder come and look at it and he told us it is a structural issue and he said not to pull the camper anywhere else, as it is a safety concern!! GD is telling me that they don't think it is a safety concern, but they haven't even looked at our camper. When we took the camper off of the truck, the split on the side near another storage compartment was made bigger!

The frame has failed on our rv it is flexing when being pulled and we are afraid it may fail completely and break free from the pull vehicle. They are calling this frame flex and seems to be common please don't wait until a complete failure happens and people get hurt to address this issue.

MY 2016 GRAND DESIGN MOMENTUM 327M USES LIPPERT AXLES. THREE OF THE FOUR GREASE SEALS LEAKED AND WERE FOUND DURING A STATE INSPECTION. THE GREASE CONTAMINATED THE BRAKES. A 2018 STATE INSPECTION AGAIN SHOWED FAILED GREASE SEALS AND CONTAMINATED BRAKES. THE WARRANTY COVERED THE COST ON THE 2016 INSPECTION, BUT NOT THE 2018 INSPECTION. I CONTACTED GRAND DESIGN REGARDING THE ISSUE. I WAS TOLD THAT NEW MODELS WERE BUILT USING DEXTER AXLES TO SOLVE THE PROBLEM. AS A REGISTERED PROFESSIONAL MECHANICAL ENGINEER, I AM CONCERNED THAT I HAVE A CAMPER WITH A 16,000+LB GVWR THAT HAS LEAKING SEALS AND POSSIBLY FAILED BRAKES. I REQUESTED NEW AXLES, BUT GRAND DESIGN DID NOT RESPOND. I AM REQUESTING THAT NHTSA ISSUE A RECALL TO REQUIRE THAT THE ISSUE IS FIXED BEFORE IT CAUSES AN ACCIDENT. I FOUND A CLASS ACTION SUIT ALREADY FILED TO ADDRESS THE ISSUE SO IT IS A COMMON PROBLEM. THANK YOU.

AFTER READING ON THE GRAND DESIGN OWNERS FORUM ABOUT LEAKING GREASE SEALS ON THE WHEELS, I DECIDED TO DO AN INSPECTION OF MY BRAKES. I HAVE PUT ONLY 500 MILES ON MY TRAILER SINCE TAKING DELIVERY ON JUNE 8, 2016. I ASSUME THAT THE TRAILER WAS DELIVERED TO OREGON BY TOWING IT FROM THE FACTORY. I REMOVED THE RIGHT FRONT BRAKE DRUM AND SURE ENOUGH FOUND A FAILED GREASE SEAL AND GLOBS OF WHEEL BEARING GREASE ON THE DRUM, BRAKE SHOES AND MAGNET.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
