Grand Design problems by model
Owners have filed 103 complaints with NHTSA about the 1 Grand Design model with enough data to profile here, covering 1 model years from 2021 through 2021. The Momentum draws the most at 103, 100.0% of the make's total.
Complaint volume tracks how many cars a make sold as much as how they held up, and NHTSA complaints are unverified owner reports rather than confirmed defects. Nothing on this page compares Grand Design against another manufacturer. Use it to find the model, then the model year, then read what owners of that year actually filed.

Reading the numbers
Across every Grand Design model year on the site, structure is the system named most often — 42 complaints, 58.3% of those filed under a named system. Individual model years diverge from that sharply, which is the reason to read the year rather than the badge.
Of the 103 complaints, 1 describe a crash.
