Service bulletin - A judder from the torque converter lock-up clutch may be felt while driving between 20 and 60 mph. The problem is typically diagnosed as a bad torque converter. American Honda investigated this and found that the torque converter is not causing the judder and the transmission is not damaged by it. The judder was caused by deteriorated transmission fluid. The transmission fluid deteriorates quicker than expected when it is exposed to intermittent high heat loads under specific driving conditions. A software update is available to maintain the transmission fluid temperature within the desirable range under all driving conditions and eliminate the potential for this judder.

The failure pattern owners describe
Owners consistently report engine misfires tied to worn piston rings, with check engine lights and codes P0301-P0304 appearing as early as 41,000 miles. Honda's TSB 13-081 describes the fix—spark plug and piston ring replacement—but parts costs alone hit $7,500 in at least one case. Some warranty repairs went through; others were denied, leaving owners on the hook. One owner also found a worn camshaft lobe requiring cylinder head replacement after 43,000 miles.
Transmission shuddering is endemic from delivery onward, felt during gear shifts and when the Variable Cylinder Management (VCM) system engages. Owners in 5-speed models complain they're excluded from official Honda bulletins even though their symptoms match documented issues in 6-speed variants. Software updates have not resolved the problem in reported cases.
Multiple owners describe alarming power loss—sudden stalling at 78 mph, 3–5 second delays when accelerating (especially dangerous on highway on-ramps or left turns), and RPM fluctuations. One owner at 100,000 miles discovered oil nearly empty despite a recent change, with critical P3400/P3497 codes triggered.
Brake lockup and VSA failures also appear, including one vehicle previously repaired under NHTSA Campaign 13V143000 that experienced recurrence. Owners report Honda denies many claims, citing design specifications, while suggesting future model-year six-speed transmissions correct the acceleration hesitation the five-speed exhibits "by design."

Failure modes owners describe
Cylinder misfire with piston ring wear
Engine misfires triggered by worn piston rings allowing oil to foul spark plugs. Check engine light illuminates with misfire codes. Some owners report engine shaking or vibration during the event.
When: 41,000 miles and beyond; can occur early in ownership (within first year for some)
Symptoms owners cite: Check engine light and misfire codes (P0301-P0304, P0302); Engine shaking or vibration; Oil fouling spark plugs; VSA warning light illumination; Jerking at various speeds
Codes mentioned: P0301, P0302, P0303, P0304
Repairs/costs cited: Owners report spark plug replacement and piston ring replacement; Honda TSB 11-033 and 13-081 address this; one owner quoted $7,500 for parts alone without labor; some performed under warranty; camshaft lobe wear also found in at least one case requiring front cylinder head replacement
Recalls/TSBs owners mention: Honda TSB 13-081 (superseded June 2019, updated October 2020) covering 2011-13 Odyssey; 2011 models require PCM software update plus spark plug and piston ring service; 2012-13 models require spark plug and piston ring service; some warranty extensions and warranty repairs performed; some warranty claims denied
Transmission shuddering and judder during shifts
Shuddering, juddering, or vibration felt during gear shifts, most commonly reported during 2-3 and 3-4 shifts in 5-speed automatic models, and at various speeds when transmission engages (VCM/Variable Cylinder Management). Owners report the issue from near-zero miles and persists despite repairs.
When: From delivery/early ownership (33 to 622 miles); affects vehicles with 5-speed and 6-speed automatics
Symptoms owners cite: Shuddering or juddering during gear shifts; Vibration in engine and steering wheel when transmission shifts; Humming vibration noise when VCM engages; Issue prevalent around 40+ mph but occurs at varying speeds; Buzzing sound intermittently
Repairs/costs cited: Honda dealer reported software control module upload performed on at least one 5-speed transmission model; issue persisted after repair; one owner reported torque converter and/or rear motor mount may need replacement; rear motor mount wear suspected in some cases
Recalls/TSBs owners mention: Honda TSB SB-12-064 referenced for 6-speed transmission models; 5-speed transmission owners report being excluded from registered complaints despite identical symptoms; some dealers stated this is normal VCM operation or that no fix exists; software updates performed without resolution in reported cases
Loss of engine power and hesitation on acceleration
Sudden loss of power while driving at highway speeds, delays of 3-5 seconds before vehicle responds to throttle input, engine acts like it might stall when decelerating or during turns, lurching forward unexpectedly after hesitation.
When: Variable mileage; reported at 13 miles, 14,050 miles, 100,000 miles; also affects early ownership vehicles
Symptoms owners cite: No response to accelerator for 3-5 seconds; Engine stalling sensation when releasing throttle; Lurching forward after hesitation; Loss of power at highway speeds; Fluctuating RPMs and acceleration
Repairs/costs cited: One owner with P3400/P3497 codes found oil level critically low (nearly empty) despite oil change two months prior, indicating possible oil consumption issue; computer update resolved power loss in one reported case
Recalls/TSBs owners mention: Honda dealer informed one owner that 5-speed transmission has inherent shift delay by design and that 6-speed models (introduced in newer model years) corrected the hesitation issue; no specific TSB or warranty extension mentioned for this failure mode in narratives
Low oil level and excessive oil consumption
Engine oil level drops significantly between scheduled oil changes, triggering P3400/P3497 codes related to variable cylinder management system. Oil warning light does not illuminate despite critical low levels.
When: 100,000 miles reported; issue occurs with regular maintenance performed (oil changed two months prior to discovery)
Symptoms owners cite: Oil level critically low (nearly empty); P3400 and/or P3497 diagnostic codes; Oil warning light fails to illuminate; Engine risk of seizure if not caught
Repairs/costs cited: Owner added 3 quarts to restore level; also required spark plug replacement twice in two years; no indication whether oil consumption or internal leakage was root cause
Brake failure and lockup
All four wheels lock up, vehicle cannot move forward or reverse, brake pedal unresponsive, rear brake lights inoperable. VSA light illuminates. Occurs while vehicle is parked and again upon restart.
When: Mileage not specified; vehicle required tow to dealer
Symptoms owners cite: All four wheels locked up; Brake pedal unresponsive (previously reported to travel to floorboard); VSA and check VSA lights illumination; Rear brake lights inoperable; Vehicle immobilized
Repairs/costs cited: Vehicle required towing to dealer
Recalls/TSBs owners mention: One 2012 Odyssey was previously repaired under NHTSA Campaign 13V143000 (powertrain) for similar brake failure, but failure recurred at 71,000 miles
Engine stall at highway speed
Vehicle stalled while driving at 78 mph, all warning lamps illuminated, then powered off. Owner managed to safely exit highway.
When: 14,050 miles
Symptoms owners cite: Complete engine stall at highway speed; All warning lamps illuminate then power off
Repairs/costs cited: Vehicle was repaired; dealer did not specify which component failed
Recalls/TSBs owners mention: Manufacturer was notified
Timing belt ticking noise at startup
Ticking sounds during engine startup, owner suspects timing belt issue but vehicle remains undiagnosed.
When: 163,000 miles
Symptoms owners cite: Ticking sounds at startup
Repairs/costs cited: Appointment scheduled for diagnostic at dealer; vehicle not yet diagnosed or repaired
