Is the Toyota Sienna more reliable than the Honda Odyssey?

Yes, the Sienna has a clear edge. Owners filed 1.9 complaints per 10,000 sold, compared with 10.1 for the Odyssey. The Sienna also has fewer recalls and fewer shop visits per year. Its weak spots are sliding rear seats and brakes that briefly let go.

Which has more recalls, the Sienna or the Odyssey?

The Odyssey has more. Federal recall records show 67 recalls across its 2018 to 2026 model years, against 28 for the Sienna. Count alone does not show severity, so check any specific van's VIN for open recall work before buying.

Which is cheaper to repair, the Sienna or the Odyssey?

They cost about the same. Independent repair-cost data puts the Sienna at $554 a year and the Odyssey at $547. The Odyssey is less likely to need a major repair, at 12% against 15%, but the Sienna visits the shop less often.

What are the biggest problems with the Honda Odyssey?

Electrical faults lead, mainly water reaching the power tailgate module, which then opens by itself and drains the battery. Owners also report a lurching 9-speed transmission, failing windshield cameras, and connecting rod bearing engine failures that some owners paid for themselves.

Which Sienna and Odyssey years should I avoid?

Avoid 2018 and 2019 for both vans, since they rank as the weakest years for each. Newer years look better in the data, but they have had less time to collect complaints, so inspect any van closely before you buy.

Honda Odyssey vs Toyota Sienna: Reliability Compared

Reliability favors the Toyota Sienna over the Honda Odyssey, because Sienna owners file far fewer complaints per van sold. Repair costs are nearly the same. The Odyssey also carries more than twice as many federal recalls.

How Do the Honda Odyssey and Toyota Sienna Generations Compare?

Two designs cover most of the Sienna years you are likely to see. The third generation ran through the 2020 model year and was facelifted in 2018. The fourth generation began with the 2021 model year, and an Anniversary Edition arrived in 2022. The two weakest years, 2018 and 2019, both belong to the third generation. The 2023 model is a fourth-generation van and ranks among the stronger years. The newest years rank well too, but they have had little time to collect complaints, so treat that as less proven.

Verdict

The Toyota Sienna is more reliable than the Honda Odyssey, scoring 74/100 vs 66/100.

Reliability favors the Sienna, and the edge is clear. Owners filed 1.9 complaints per 10,000 sold, against 10.1 for the Odyssey. Federal recall records show 28 recalls for the Sienna and 67 for the Odyssey. Repair costs are nearly identical, so the gap comes from how often things go wrong. The Odyssey piles up water-damaged tailgate modules, lurching transmissions, dead cameras and engine bearing failures. The Sienna is not clean, since sliding rear seats and brief brake dropouts worry owners, but its complaint load is far lighter.

What Are the Common Problems With the Honda Odyssey and Toyota Sienna?

Trouble is spread across costly systems on the Odyssey. Water leaks short the power tailgate module, and the gate opens on its own and drains the battery. The 9-speed transmission hesitates and lurches. The windshield camera fails and takes cruise and braking aids offline. Connecting rod bearings can fail and seize the engine. Crashes are linked to the transmission, the camera system, the engine and the electrical system. The Sienna's complaints center on rear seats that slide, brakes that let go briefly while slowing, and some transmission failures. Its crash-linked reports sit in the brakes and electrical system, and none appear for its power train.

Who Should Buy the Honda Odyssey vs the Toyota Sienna?

If you want the lower chance of trouble, buy the Sienna. Owners filed far fewer complaints per van sold, and recalls are fewer. Check that the rear seats stay locked in place, which matters if you mount child seats. Take a test drive with several stops and notice any brakes that seem to let go. Target 2023 where budget allows, and avoid 2018 and 2019, the weakest years. Choose the Odyssey if a lower chance of a major repair matters most to you, since its chance is a bit lower than the Sienna's. Then protect yourself. Ask for proof of rod bearing recall work, look for water stains around the tailgate and headliner, and test the transmission pulling away from a stop. Confirm the driver-assist camera runs with no warning messages. Skip 2018 and 2019, the weakest years. A 2024 ranks among the stronger years, though newer vans have had less time to collect complaints.
