Comeback Repair Investigation Agent: what goes in, what the agent does and what you get

What it does

A car returns three weeks after a brake job with the same noise, and the shop argues about who is at fault. When a comeback is opened, the agent pulls the original repair order with the parts, codes, test results and photos, and compares them with the new complaint and findings. It lists the likely causes: a wrong or defective part, a missed step, a related fault or a new problem. It tests each against the records, for example the part number against the catalog, torque notes, test drive notes and the mechanic who did it. It then recommends whether the shop should cover the work and what the no-charge plan would cost. It records the cause in the shop's log so that patterns appear. Edge case: the customer's driving has changed since the first repair. The service manager approves any goodwill decision.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

Each possible cause is supported or ruled out by the records. If the shop's work is the likely cause, the agent recommends a no-charge repair. If not, it explains why.

  • Treat a return for the same complaint within 30 days or 1,000 miles as a comeback
  • Recommend no charge when records show a shop or part error
  • Check the part number against the catalog every time
  • Record the cause even when the shop is not at fault

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Comeback window (default 30 days or 1,000 miles)
  • Cost limits for goodwill
  • Records to review
  • Cause categories
  • Supplier claim rules

What keeps you in control

It always asks you first

  • Service manager approves any no-charge or shared-cost decision
  • Service manager approves a claim to a parts supplier

Hard limits

  • Do not blame an individual without records
  • Never promise a refund to the customer

It stops when

  • Done: cause recorded and plan approved
  • Stop: the original records are missing, tell the manager and list what is needed

An example run

What happensA truck returns 3 weeks after a rear brake job with a squeal. The agent finds the pads on the original order are the economy line while the front axle used the premium line, and the torque note is missing. The records support a parts mismatch and a missed note. It proposes a no-charge pad swap costing $85 in parts. The manager approves and the cause is logged.
