GarageCalc What the data says
Structure:body accounts for about 37% of this year's Grand Design Solitude complaints. That is a moderate concentration; worth knowing, but complaints are spread across several areas.
The 2021 model year contributes 6 complaints (32%). No single model year dominates, so this looks like a line-wide pattern rather than one bad year.
Complaints are down year over year, 41 to 19 (-54%), while the market overall rose about 2%. Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Grand Design Solitudes are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.
