Used 2018 Toyota Sienna buyer's checklist

  1. Run the VIN at nhtsa.gov/recalls. 7 recalls this year — ask for proof of repairs.
  2. Power Train — 20 owner reports. Test-drive through all gears, including reverse; note slipping, harsh or delayed shifts.
  3. Fuel/Propulsion System — 9 owner reports. Smell for fuel around the car and in the cabin, check that it starts easily when warm, and look at the oil dipstick for a fuel smell or rising level.
  4. Structure › Body — 5 owner reports. Open and close every door, the hood and tailgate; look for rust or misaligned panels.
  5. Mileage to watch. Owners typically reported problems around 30,000 miles; ask what was repaired near that point.
  6. Before you pay: service records, a history report and an independent inspection.
