What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2016 Grand Design Momentum, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
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
Frame tore/broke at welds where upper deck(living room) attaches to frame. Fiberglass on exterior tore as a result.

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.
AXLE SEALS LEAKED ALLOWING GREASE TO ENTER BRAKE DRUMS AND COAT SHOES, MAGNET AND DRUM. CONFIRMED BY LIPPERT COMPONENTS WHILE VEHICLE WAS AT GRAND DESIGN SERVICE SHOP.

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.
