9-speed and 6-speed transmission troublemajor
2016 launched the ZF 9-speed automatic (higher trims, push-button shifter) alongside the carryover 6-speed (lower trims, lever shifter), and both have known weaknesses. Owners of the 9-speed report clanging, refusal to accelerate, and internal failure; one independent shop diagnosed a 6-speed at 104,000 miles with a cracked valve body stuck in limp mode (code P0746) after three replacement valve bodies failed to fix it — the conclusion was a full transmission. A mechanic who owns a 2016 himself puts the repair at $5,000–$10,000. On the 6-speed a separate lockup judder appears between 20 and 60 mph; Honda's own bulletin found the cause was not a bad torque converter but transmission fluid that deteriorates faster than expected under heat. Test-drive through all gears and check the fluid and service history.
