About the 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 this page

Vehicle-specific numbers are distinct owner reports from the published aggregate table. Related owner situations come from a validated graph, not from inventing a symptom count out of the component total. General guidance is the same for every vehicle and is not a diagnosis of yours.
