Reliability & Common Issues

2020

Value & Cost of Ownership

When purchased new, the 2020 Odyssey and Sienna had very similar starting MSRPs, making initial acquisition cost a wash at the base level. In the used market (as of 2024), 2020 models typically range from approximately $25,000 to $35,000, depending heavily on trim level, mileage, condition, and optional features like AWD for the Sienna. Insurance costs for minivans are generally moderate and tend to be similar for both the Odyssey and Sienna, varying more by individual driving record, location, and coverage choices than by specific model. Maintenance costs for both vehicles are typically low to average, as both Honda and Toyota are renowned for their reliability and availability of parts. The Sienna might have a slight edge in long-term maintenance costs due to its more traditional 8-speed transmission and proven, less complex mechanical platform, potentially leading to fewer expensive repairs over its lifespan. Resale value is a strong point for both minivans. Toyota vehicles, including the Sienna, are legendary for their ability to retain value exceptionally well, often slightly outperforming competitors due to their reputation for long-term reliability and lower overall ownership costs. The Honda Odyssey also boasts very good resale value, though historically it might trail the Sienna by a small margin. The AWD option in the Sienna can further boost its resale value in regions where it is desirable.
