OwnerReports

About the data

Everything here comes from one public source, and it is important to understand what it does and does not prove.

Where it comes from

The US National Highway Traffic Safety Administration publishes every complaint an owner files about a vehicle. We download the full corpus daily — 2,123,582 complaints as of the last build — and aggregate it into a failure profile for each model year.

Recalls are fetched live from NHTSA when you load a page, so they are always current. NHTSA data is US federal government work in the public domain.

What it cannot tell you

Complaints are not confirmed defects

Anyone can file one. They are unverified reports of what an owner believes happened. A complaint is a signal, not a finding.

Volume tracks sales, not reliability

A model that sold two million units will always collect more complaints than one that sold thirty thousand. Comparing raw totals across different models is meaningless. Comparing model years of the same car is useful.

Only unhappy owners file

Nobody reports a car that works. The data describes the shape of the failures, not how common failure is.

This is not safety advice

We report what owners filed. We do not assess whether a vehicle is safe to drive. For that, talk to a mechanic, and check NHTSA for open recalls on your specific VIN.
