How do I check an auto repair shop’s comebacks and warranty work?

Ask for the shop’s records of repeat visits and warranty claims, and read them for patterns. Find out who pays when a repair fails, whether the shop backs its work in writing, and who is responsible for jobs done before the sale. The answer belongs in the purchase agreement.

A comeback is a vehicle returning for the same problem. Ask how the shop tracks them: work orders, notes, parts returns, and any warranty claims against suppliers. A shop that cannot say how many come back may not know. Read a sample of recent repair orders yourself, and ask the service writer what the mechanics say about repeat problems.

Look for patterns. Do comebacks cluster around one technician, one type of job or one supplier’s parts? A single rushed repair is different from a regular weakness. Ask what the shop did to put things right and how much it cost in time, parts and goodwill. Review online comments and ask about customers who left unhappy.

Then settle responsibility. Customers will expect the shop to stand behind recent work whoever owns it, so ask what warranty the shop offers and how it is written on invoices. Ask your lawyer how the agreement should treat claims from before closing. Discuss with the seller how any open claim will be handled, and who deals with the customer. If the shop sells extended coverage, ask what it promises, who underwrites it and how claims have been paid.

Key takeaways

  • Ask how comebacks and warranty claims are tracked.
  • Read recent repair orders and look for patterns.
  • Review what warranty is promised on invoices.
  • Settle in the agreement who handles claims from before the sale.
