Recall record

Graco — 17 on NHTSA's record.

That is the record of the brand — not a verdict on this model. A recall names specific models and manufacture-date ranges, and a seat missing from the record is not "recall-free": check nhtsa.gov/recalls with the model and date of manufacture on your seat's label.
