What stands out
Electrical accounts for 45% of every owner complaint on file for this vehicle — the dominant problem area across 7 categories tracked.
Owners have filed 81 electrical 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.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The dominant issue: auto idle stop fails to restart. Drivers pull up to a red light, the system shuts the engine off as designed, but when they release the brake or accelerate, nothing happens. The vehicle sits dead in traffic. Some owners restart immediately; others wait minutes, pushing the start button repeatedly while cars honk behind them. Flashing warning lights and vague error messages appear. Battery replacements and starter replacements have not fixed the problem permanently. One owner's dealership just told him to manually turn off idle stop every single time he starts the van—defeating the feature's purpose. Honda has acknowledged the issue but offers no solution; a NHTSA investigation (EA25004) is underway.
Beyond idle stop, owners report difficulty starting the engine (slow cranks, hesitation) even when the idle-stop feature is disabled. The original battery failed at 2 months; replacements test good but failures continue.
Secondary electrical issues plague these vehicles: sensor contamination from road salt triggering unintended shutdowns, automatic headlights stuck on, cruise control speed mismatches, door locks that won't engage or disengage, infotainment screens going black, parking sensors throwing false alarms, and one vehicle with a steering column deemed unsafe by the dealership.
Dealerships consistently claim they cannot duplicate the faults, despite owners experiencing them repeatedly and describing them in detail. The consensus among complainants: this is a widespread defect affecting many 2025 Odysseys, not an isolated incident.

Failure modes owners describe
Auto Idle Stop failure to restart
Engine shuts off as designed during idle-stop, but fails to restart when brake is released or driver attempts to accelerate. Vehicle stalls in traffic, requiring manual restart via push-button.
When: Occurs at traffic lights, stop signs, and in intersections. Ranges from rare to weekly. First reported occurrences May 2025 onward; pattern evident from purchase (Dec 2024) through March 2026. Mileage 9,300 to 46,880 miles.
Symptoms owners cite: Engine shuts off at idle stop as designed; Engine fails to restart when brake released; Multiple restart attempts required (up to 3–10+ attempts, sometimes minutes elapse); Struggling, grinding, or weak cranking noise during failed restart attempts; Battery warning light illuminates during failure; Flashing dashboard warning lights; Brief error messages (contents often unread due to traffic stress); Vehicle becomes unresponsive and may lock in Park; Violent restart with sputtering/choking sound when engine finally turns over; Occasional loss of all power until manual restart
Codes mentioned: Battery light, Idle Stop Not Available message, System failure message (unspecified)
Repairs/costs cited: Battery replaced multiple times (no permanent fix); low-pressure fuel pump replaced (no permanent fix); starter motor replacement authorized/recommended in some cases; body control module replaced (failure persisted); dealerships unable to replicate issue; no permanent repair solution provided. Owners advised to manually disable auto idle stop on each vehicle start.
Recalls/TSBs owners mention: Honda acknowledged issue exists but provided no diagnostic solution or repair procedure. Dealerships instructed to recommend manual disabling of auto idle stop feature (negating design purpose). NHTSA investigation EA25004 referenced by multiple complainants; investigation ongoing.
Difficulty starting / slow cranking / hesitant start
Vehicle cranks slowly, hesitates, or nearly fails to start on first or early attempts. Occurs intermittently regardless of temperature. Original battery was replaced under warranty; problem persists post-replacement.
When: Intermittent, occurs both in cold conditions and after vehicle has been parked briefly (within minutes of parking after 20+ min drive). First reported 2 months post-purchase (Feb 2025); ongoing through March 2026. Mileage 9,000–23,000 miles.

Over the past month, I have experienced several incidents where my 2025 Honda Odyssey’s Auto Idle Stop (AIS) system failed to restart the engine after stopping at traffic lights. Each time, the engine did not turn back on when I released the brake, leaving me stalled in traffic and prompting error messages on the dashboard. There is currently no way for owners to permanently turn off this…
In January 2025, we drove to Florida from Michigan. When I started my car every signal light came on. It would not allow me to shut down. We drove it to Orlando Honda and they said the sensor light was covered with road salt. It was very scary. In November 2025 we were driving home in a snowstorm. The sensor in the front got covered and shut down the speed control, warning lights of crossing…
My 2025 Honda Odyssey has been completely shutting off after the stop-start shuts the engine off. When the car actually “stalls” is when I let off the brake and it’s time to start going. Then I hear a ding, the dash lights come on, and I have to frantically hit the ignition button. This is happening at stop lights where there is the risk for other cars to safely go when the light turns green. I…
Vehicle shuts down and will not restart. So far this has happened three times. After a long delay, took foot off gas, held brake and pushed start and would not start. On third attempt vehicle was very labored on start
Idle stop engine turned engine off at a stop light. When the foot was removed from the brake pedal the engine struggled to start up. It took several attempts to get the engine to start up. This has occurred before and the dealer replaced the battery. However, it is now happening again. There were no warnings .
. When auto start/stop engages at stoplights and fails to restart radomaly but not always, the vehicle remains stationary and blocks traffic lanes when battery light turns on. This creates hazardous conditions where other vehicles must maneuver around a stalled vehicle in intersections, risking rear-end collisions and traffic disruptions. Dealer was not able to replicate Issue as this, i expeted…
Stopped at red light. Auto start/stop engaged. Light turned green let off of brake and pressed gas. Engine did not start. Couple seconds later engine started.
The vehicle intermittently fails to restart after the auto start/stop stopped the engine. This happened several times when stopped at a traffic signal, nearly causing an accident when cars behind expected to move after the traffic signal turned green. There were no warnings or indications prior to the failure to start. Multiple attempts to restart the vehicle failed until at least a minute or…
