The Honda Odyssey is feature-rich but has had recurring transmission problems. The 2019-2021 examples after the 9AT/10AT software fixes are the safest used buy. Older 2003-2007 Odysseys had documented 5-speed transmission failures.
Buy: 2019-2021 Odyssey (J35Y6 with 10AT, post-fix)
Avoid: 2018 launch (transmission) and 2003-2007 (5-speed failure)

The 3.5L J35Y6 V6 with the 10-speed (Touring/Elite) or post-fix 9-speed (lower trims) is the most refined Odyssey powertrain. Major improvement over launch-year 5th-gen.
More on this issue →ZF 9HP automatic on launch-year 5th gen had hard shifts, hesitation, and torque-converter complaints. Honda issued multiple TSBs. Class action filed.
More on this issue →Second-gear cluster failures across 1st and 2nd-gen Odyssey, Pilot, Acura MDX. Honda extended warranty on affected VINs but most are now past coverage.
More on this issue →Variable Cylinder Management causes oil consumption, plug fouling, and TC shudder. VCMTuner II module disables it cheaply.

The 2020-2021 Odyssey is the best modern pick. Post-9AT/10AT software fixes, refreshed infotainment, and refined J35Y6 V6 produce the lowest complaint volume.
No. The 5th-gen launch year had widespread 9-speed transmission complaints, Display Audio crashes, and idle-stop battery failures. Avoid this year.
You can buy them with a VCMTuner II module ($200-300) and strict 5000-mile oil intervals. Without the bypass, expect oil consumption past 100,000 miles.
Sienna for long-term reliability (no VCM, no 9AT issues, AWD option). Odyssey for entertainment system, magic seat, and driving feel.
A maintained Odyssey with the J35 V6 reaches 200,000-250,000 miles. VCM bypass extends life noticeably. The transmission is the primary failure mode.
Mostly. Multiple software updates and a class-action settlement provided remedies. By 2020+ the calibration is reasonable. The 10-speed in Touring/Elite trims is preferred.
