Toyota Sienna 2011–2020 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes, not generic used-car advice.

1. Check 01

   Cycle BOTH power sliding doors several times from the dash buttons, key fob, and door handles. Slow, grinding, or stalling movement means a fraying cable or tired motor. That is a known, common failure on 2011–2018.

2. Check 02

   Run the VIN at nhtsa.gov/recalls or Toyota's recall lookup. Key ones: sliding-door recall G04 (2011–2016), Denso fuel-pump recall (2017–2020), Takata airbag (2011–2014). Walk away from open safety recalls, or make the seller close them first.

3. Check 03

   On 2017–2018: drive it below 30 mph with light throttle. Hesitation off the line, a delayed or harsh 2-3 upshift, or a high-pitched whine points to the early 8-speed problem. Ask for records of the TSB software update or transmission replacement.

4. Check 04

   Cold start: listen at the front of the engine for a wobbling/rattling water pump bearing, and look for pink coolant crust or streaks below the pump.

5. Check 05

   On 2011–2012: check the front tires for uneven/inner-edge wear and feel for steering pull. The inner tie rods on the 2011 were a top complaint.

6. Check 06

   On AWD vans: confirm what tires are on it. Factory fitment is run-flats with NO spare tire; mismatched cheap tires or a bare trunk floor tells you how the last owner treated the tire budget.

7. Check 07

   Check that the second- and third-row seats latch, fold, and slide properly. Hardware is expensive and often ignored.

8. Check 08

   Look for oil seepage at the timing cover (common minor 2GR weep) and verify consistent oil-change records.
