Symptom Checker
Pick what you notice and the closest symptom to see the questions that narrow it down, the possible causes and the risk.

What do you notice?
Which one is closest to yours?
No symptom in this group matches. Try other words or go back.
How to use it
Choose a group (noise, smell, leak, vibration, smoke, starting, driving), then the symptom that sounds most like yours. You get the questions mechanics ask, the possible causes and how urgent it is.
How it is calculated
The checker uses only PitClue’s published symptom pages: their questions, causes and risk level. It does not add diagnoses of its own and does not rank causes, because the real cause depends on the car.
