About this data
Component evidence comes from structured complaint categories and reviewed component mentions in complaint summaries. Owner-situation evidence comes from reviewed symptom language in complaint summaries. Reports are signals, not diagnoses.
How to read the counts
Counts are distinct owner reports involving a canonical component. They are not a failure rate, probability, or share of vehicles sold. A complaint involving a component does not prove that component caused the problem. Parent NHTSA system buckets are not counted as the part itself.
