Before diagnosing the Toyota Prius
Use the right check before buying a part
A symptom can have several causes. These guides help separate a useful clue from a diagnosis that still needs testing.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
Read guide ↗Words owners use
The workshop phrase may not be yours.
Choose the description that sounds closest, then read the complete symptom pattern.
