Mobile Car Diagnostic FAQ
- How much does a mobile diagnostic cost?
A check-engine diagnostic starts at $99, all-in — the scan, labor and the trip included, and it's credited toward the repair if you book it with us. Your exact flat price appears after you select your year, make and model.
- How long does a diagnostic take?
Most diagnostics take about 45 minutes in your driveway. You'll get a text when your mechanic is on the way.
- Is it safe to keep driving with the check-engine light on?
A steady light usually means it's safe to drive carefully to get it checked soon; a flashing light means stop driving immediately, since it often signals a misfire that can damage the catalytic converter.
- Will the diagnostic fee be wasted if I don't need a repair?
No — you only pay the flat diagnostic price, and if you do need a repair, that fee is credited toward the cost of fixing it.
- Do you offer a warranty on repairs after a diagnostic?
Yes. Any repair we complete is covered by our 12-month / 12,000-mile warranty on parts and labor, honored anywhere we operate.
