What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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 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.
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.
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.
The grease seals on the drums leaked from the factory and allowed the brakes to be contaminated. More details are at http://www.granddesignowners.com/forum/showthread.php/8531-poll-how-many-of-you-have-had-your-grease-seals-fail?p=104942&viewfull=1#post104942
