Before paying a shop's $30–$100 diagnostic fee, know that AutoZone does the first diagnostic layer free at every US store: Fix Finder reads your check engine, ABS, and maintenance lights in under a minute and prints/emails a plain-English report; they'll also test your battery, alternator, and starter free, recharge a weak battery free, help install wipers, and lend specialty tools through Loan-A-Tool. No purchase required — it's a standing service.
