On the 7 measures below that do not grow with sales, the Sienna and the Odyssey split evenly (1 each, the rest too close to call).

Counts are not adjusted for sales. The more cars of a model there are on the road, the more complaints it draws, so the raw totals above say a lot about sales. Everything below compares shares of each model's own complaints, the mileage problems start at, recalls per model year and each model's years against its own median.

Share of each model's own complaints, with the count beside it. "Most in" links to the symptom sheet for the model year with the most reports of it, and the mileage is the median from reports that gave one.

When problems start

Problems show up at about the same mileage on both. Half the Sienna complaints that give a mileage come before 34,000 miles, and half the Odyssey complaints before 35,000. 66% of Sienna reports and 62% of Odyssey reports come before 50,000 miles. Older model years have had longer to reach high mileage, so a window that runs to recent years pulls both medians down.

Each bar is that model year's complaints for each year on the road, divided by the same figure for a typical year of the same model (the dashed line). Measuring each model against itself takes the sales gap between the two out of the picture, so they can share a scale. Years too new to judge are left out.

Recalls and investigations

The two draw recalls at about the same rate: 2.8 campaigns per model year for the Sienna and 2.7 for the Odyssey. A recall counts once however many cars it covers, so this figure does not grow with sales the way complaint totals do.

Toyota Sienna

17 recall campaigns and 2 NHTSA investigations across these model years. Most recalled: airbags (3), structure (3) and service brakes, hydraulic (2).

  • 25V-086 (seats) covers 3 model years
  • 25V-877 (equipment adaptive/mobility) covers 3 model years

Investigations

  • DP22005: Pedestrian alert sounds (closed, led to a recall)
  • EA21002: Desiccated air bag inflator rupture (open)

16 recall campaigns and 3 NHTSA investigations across these model years. Most recalled: seats (4), airbags (4) and fuel system (3).

  • 23V-858 (fuel system) covers 4 model years
  • 25V-877 (equipment adaptive/mobility) covers 4 model years

Investigations

  • DP26005: Inadvertent deployment of air bags (closed)
  • PE25018: Inadvertent deployment of side air bags (closed, led to a recall)
  • EA25004: No restart after auto start/stop engages (open)
