When the Auto Idle Stop is engaged, I have now had 3 instances of the engine completely stalling when at a stop. Not only has the engine stalled, but I have difficulty getting the engine to restart. It has been very scary, as it has left me disabled at busy intersections while I struggle to get my van to start so I can move and pray nobody hits me while I sit there. I've even had to open the…

What stands out
Owners have filed 32 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: The 2025 Odyssey has a serious and persistent problem: the Auto Idle Stop feature causes the engine to stall at traffic lights and fail to restart, leaving owners stranded in traffic with no warning. Battery replacement and dealer visits have not fixed the issue for most owners, and Honda has not provided a working solution despite multiple NHTSA complaints.
The dominant complaint is engine stalling tied to the Auto Idle Stop feature kicking in at red lights and stop signs, with no warning lights or messages before the engine dies. Owners report the vehicle becomes completely immobilized at intersections—stuck in Drive and unable to restart immediately—requiring 30 seconds to several minutes of frantic button-pressing or a shift to Park before the engine will turn over again. This happens intermittently but repeatedly, with many owners experiencing 3–4+ incidents over a 2–3 month window despite the vehicle having under 23,000 miles.
Dealerships have replaced batteries on multiple owners and in one case the starter motor under warranty, but the stalling continues. Several dealers claim they cannot reproduce the issue on test drives and have suggested owners simply disable the Auto Idle Stop feature—essentially telling owners a new standard feature is broken and unusable. One owner reported a dealership claiming software updates fixed the problem when they actually made none. No owner reports a successful repair. One owner, terrified after multiple incidents, left the vehicle at the dealer undiagnosed. The problem is correlated with NHTSA Action EA25004 (Engine and Engine Cooling) but owners say Honda has not directly inspected their vehicles or offered real solutions, only workarounds.
Failure modes owners describe
Engine Stalling During Idle Stop / Auto Start-Stop
Engine shuts off unexpectedly while the vehicle is stopped in traffic (at red lights, stop signs, intersections) when the Auto Idle Stop feature is engaged. The engine cuts power without warning and the vehicle becomes immobilized until manually shifted to Park and restarted.
When: Begins shortly after delivery; first documented September 2025; some complaints as early as 9-10 months of ownership; mileages cited: ~10,000–23,000 miles
Symptoms owners cite: Engine shuts off completely while idling at traffic lights, stop signs, or intersections; No warning lights or dashboard messages prior to stalling; Vehicle immobilizes in traffic, blocking other drivers; Stalling occurs intermittently, sometimes 3–4+ times over weeks or months; May occur during adaptive cruise control operation
Repairs/costs cited: Battery replaced at dealership (multiple owners report battery replacement did not resolve); starter motor replaced under warranty in at least one case; dealership unable to reproduce issue on multiple occasions; one dealership advised disabling Auto Idle Stop feature as workaround; software/firmware updates claimed by one dealership but owner disputed the claim
Recalls/TSBs owners mention: NHTSA Action Number EA25004 (Engine and Engine Cooling) referenced by owners; no manufacturer direct inspection reported; Honda of America requested but no documented assistance provided
Engine Failure to Restart After Idle Stop Disengages
When the driver releases the brake after the Auto Idle Stop has shut off the engine, the engine fails to restart or requires multiple restart attempts. The vehicle is stuck in Drive or the transmission will not shift out of Drive until the engine is restarted.
When: Intermittent; occurs within the first 6–9 months of ownership; multiple incidents per owner over 2–3 month spans
Symptoms owners cite: Engine struggles to crank, taking several seconds before turning over; Complete failure to restart on first attempt; requires 2+ attempts; Vehicle locked in Drive; cannot shift to Park until restarted; Restart delay of 30 seconds to several minutes; Problem does not occur when Auto Idle Stop is manually disabled; Battery warning light illuminates on some occasions
Repairs/costs cited: Battery replaced; starter motor replaced under warranty; dealership unable to reproduce on test drives; one owner reported abnormal beeping from Start button and stiff brake pedal during failure; one dealership suggested low battery voltage and advised disabling Auto Idle Stop; vehicle left at dealership unrepaired in at least one case
Recalls/TSBs owners mention: No documented manufacturer assistance; multiple dealership visits without resolution in most cases
Hard Starting / Slow Crank at Initial Start
Vehicle struggles or is slow to turn over when starting from a complete stop, distinct from the Idle Stop restart failures. Cranking is labored and the vehicle may eventually start after multiple attempts.
When: Occurs at initial start; noted within first year of ownership
Symptoms owners cite: Engine struggles to turn over on initial start; Slow cranking before engine catches; Requires multiple start attempts
Repairs/costs cited: Battery replaced; one dealership advised disabling Auto Idle Stop to prevent starter strain; one owner reported replacement of starter motor (though primary failure mode was Idle Stop)
Recalls/TSBs owners mention: No documented recalls or service bulletins provided to address starting difficulty
Loss of Power / Stalling While Driving
Engine loses power or stalls while driving at speed, separate from Idle Stop events. Vehicle may be difficult to restart or require several attempts to recover.
When: Reported at various speeds; one incident at 40 MPH mentioned; mileage ~12,000–18,886 miles
Symptoms owners cite: Loss of automotive power while driving; Engine stalls mid-traffic; Failure to accelerate as intended after restart; Check engine warning light illuminated (in one case); Intermittent occurrences
Codes mentioned: Check engine light (reported in one narrative but code not specified)
Repairs/costs cited: Cause could not be determined by dealership in the one case where the vehicle was brought in; one owner left vehicle at dealer undiagnosed and unrepaired due to safety concerns
Recalls/TSBs owners mention: Manufacturer notified in one case but no assistance provided; vehicle unrepaired

When the vehicle is stopped, and the auto-shut off engages, the vehicle will turn off, and the vehicle has to be restarted. Quite dangerous when in traffic and the vehicle is dead due to the auto-shut off not starting again. The fix is believed to be an updated starter engine computer and starter motor.
