Complaints

What owners reported to NHTSA about a model year, as counts by component.

These are owners' reports. They are not verified, and a count is not a rate. No complaint itself is available here: only how many there are.

Path parameters

idstring required

A vehicle id. Complaints are counted by year, make and model; a submodel or an engine in the id is set aside.

Response

The counts. All zero when no complaint names the model year.

as_ofstring nullable

The day the complaints were current.

attributionstring[] required
complaintsinteger required

Every complaint about the model year. Not a rate: a model that sold more has more.

crashesinteger required
firesinteger required
injuriesinteger required
median_kminteger nullable
median_milesinteger nullable
notestring required

What these counts are and are not.

report_urlstring required

Where an owner files a complaint with NHTSA.

verifiedboolean required

Always false. A complaint is an owner's report. Nobody has verified it, and a count of complaints is not a finding that anything is wrong with the vehicle.
