Used 2012 Kia Optima buyer's checklist

  1. Run the VIN at nhtsa.gov/recalls. 6 recalls this year — ask for proof of repairs.
  2. Safety-critical recall. At least one recall carries a "Do Not Drive" or "Park Outside" warning. Do not buy until the VIN shows it was repaired.
  3. Engine — 460 owner reports. Cold-start the engine, listen for knocking, and watch for warning lights or hesitation on acceleration.
  4. Steering — 160 owner reports. Turn lock-to-lock while parked and on the road; listen for noises and feel for heavy or loose steering.
  5. Electrical System — 126 owner reports. Test every window, lock, light, screen and USB port; check the battery age.
  6. Mileage to watch. Owners typically reported problems around 84,000 miles; ask what was repaired near that point.
  7. Hybrid system. Check for hybrid-system warning lights and ask whether the high-voltage battery has been replaced or is still under warranty.
  8. Before you pay: service records, a history report and an independent inspection.
