Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Noticed the frame on our trailer is starting to bulge. We are part of a Facebook group for our specific trailer and apparently this is a common problem/ occurrence. We contacted both Grand Design and Lippert for assistance with fixing the issue which they have done for many but since we are second owners they are refusing to help. This is a major safety issue and of left unfixed could potentially cause a bad accident/ incident. …”

NHTSA complaint #11633521, filed 2025-01

“Component failure : Left rear tire showed signs of wear. Replaced the tire and upon reinstalling checked the hubs and brakes. All good.

This trailer at minimum would have lost the axle and torn apart the trailer. …”
