Frequently Asked Questions
What breaks on used Siennas?▼
The power sliding doors lead: cable and motor wear runs $300–$1,400 per door, and a separate door-latch safety recall (free fix) applies to many 2011–2016 vans — verify by VIN. The V6's water pump weep ($500–$1,200) is the other line item.
Sienna or Odyssey — which is more reliable?▼
The Sienna's drivetrain has the edge (no torque-converter shudder pattern and no VCM oil use), while both share sliding-door wear. The Odyssey counters with a nicer drive. Either is a sound buy with its known items checked.
