Industry Overview

Diagnostic fees can be unclear and are sometimes used to justify inflated or vague repair estimates.

⚠️ Watch Out For β€” Common Upsells

  • β€’Free or cheap inspections used as a funnel for upsells - you might get a long list of β€œneeded” repairs afterward
  • β€’some shops may exaggerate issues during a courtesy inspection to generate business
  • β€’not separating critical issues from minor or preventative ones, making it seem like everything is urgent.
  • β€’Charging for diagnostics without resolution or value
  • β€’Charging separately for each issue scanned
  • β€’Using vague findings to upsell repairs

❓ Questions to Ask Your Mechanic

  • β€’β€œCan you prioritize the findings? Which issues are safety-critical vs maintenance?” - After an inspection, ask the mechanic to distinguish what truly needs immediate repair. If buying a car, ask for a written report. If the list is long, consider a second opinion before agreeing to all repairs.
  • β€’Will the diagnostic fee be applied to the repair cost if I approve the work?
  • β€’Can I have a copy of the diagnostic codes or results for review?
