My 2025 Honda Odyssey shut off in Auto Idle Stop while at a busy intersection. The car was unresponsive and would not engage the motor. After five minutes of trying to turn the car off and on, it eventually restarted and the motor came back to life. This issue put me at great risk of bodily harm. Given the fact the car was unresponsive in such a surprising way, I was very lucky not to have cars crash into me from behind as they few by for the 5 minutes I was stranded. This is the first instance and has not been reproduced as I am too worried to drive the car now. No inspection of the vehicle has been completed as this incident just occurred. No waring light prior to the incident, but the battery warring light did come on while the car shut off and unresponsive.

Vehicle was using an off ramp and shutdown in the middle of a lane. It was 10:00pm and all systems were shutdown, including lights. Vehicle refused to restart and could not be placed in neutral, the vehicle could not be removed from the interstate off ramp. This issue has been brought to the attention of Honda, the started assembly was replaced on March 5, 2026. This vehicle has been delivered to Honda for similar electrical/starter issues 4 times since October 27, 2025. The first report was filed with Honda on October 27, 2025 with all lights on dashboard lit when vehicle was active. Had to wait until a tow truck arrived before vehicle could be safely removed from the scene.
Engine fails to restart after auto off.
Starter failure due to heat. Vehicle has failed to restart several times while stopped in traffic and at a traffic light due to the Auto Idle Stop function.
I am filing a safety complaint regarding a recurring, severe defect involving the 2025 Honda Odyssey's starter motor and the factory-installed Auto Idle-Stop (idle-stop) system.While driving, the vehicle's Auto Idle-Stop system engaged as designed when coming to a complete stop in traffic. However, when trying to accelerate, the vehicle failed to restart automatically. The engine completely stalled out on an active roadway. Attempts to manually override the system and restart the vehicle using the ignition button failed completely, resulting in an immediate and dangerous loss of propulsion.This defect presents a severe and immediate traffic hazard, as it unexpectedly leaves the vehicle completely disabled and stranded in active lanes of traffic. It strips the driver of the ability to clear the roadway to safety, significantly increasing the risk of a rear-end collision. Multiple occupants, including passengers in the rear seats, were exposed to extreme danger due to this sudden propulsion failure.Despite bringing the vehicle to an authorized Honda dealership, the manufacturer has failed to provide a permanent safety remedy. Also Honda corporate has deny warranty replacement for the starter that’s causing the issue.
The vehicle experiences sudden, intermittent engine stalling while idling (either when coming to a stop at traffic lights or while idling in traffic). The engine shuts down completely and fails to automatically restart via the Auto Idle-Stop feature, forcing the driver to manually cycle the ignition or shift to Park to restart. This has happened multiple times since I bought the car at Stevens Creek Honda in September 2025 and have taken it to get it service at Livermore Honda in November 2025 and again in August 2026. The dealer has been notified but the defect remains unresolved, presenting an immediate safety risk of being rear-ended in active traffic due to sudden loss of propulsion.
Engine failed to restart during Auto Idle Stop event. Nearly created an accident.
While waiting at a stop light, the engine turned off and the vehicle forced itself into park. Taking my foot off the brake, had no effect. I was not able to put the vehicle back into drive. I had to shut off the engine and restart it in order to drive again. Of note, the AC and carplay were running at the time of the engine failure. No warning lights appeared. Cars behind me were honking at me. I have an appointment scheduled with the dealership to assess the auto-idle function.
Vehicle turns off unexpectantly at red lights/intersections when auto idle engages and will not restart automatically. It takes 1 to 2 minutes for the vehicle to restart. There is no predicting when the issue occurs. Causes vehicle to be immobile in busy and congested intersections which results in safety issues to us and oncoming traffic. There is a potential for a head on or T-bone collision when this happens. We've had starter replaced before at 22,000 miles and now we have to do it again at 36,000 miles. The Honda dealer said he sees this issue twice a week so we aren't the only ones. To my knowledge, Honda has yet to come out with a permanent repair.
At a stop light and in traffic several times the vehicle has failed to restart when stopping for the idle start/stop. The vehicle will not immediately restart and takes several minutes, leaving me idle in the middle of traffic. The vehicle has been to the dealership several times for repair however I'm still experiencing this issue. This is a serious safety concern for my family.
While stopped at a red light or intersection, the vehicle's Auto Idle Stop feature engages and shuts off the engine as designed. However, on multiple occasions, the engine has failed to automatically restart when the brake pedal is released. The vehicle remains stalled and unresponsive in the middle of the intersection or traffic lane, creating a safety risk to myself and other drivers, particularly at busy intersections. In some instances, the vehicle needed to be fully powered off and restarted before it would move again. This is a known and widely reported defect affecting Honda and Acura vehicles with the Auto Idle Stop system, currently under the federal safety agency Engineering Analysis EA25004. The problem has occurred repeatedly and unpredictably, with no consistent warning beforehand. The vehicle and its Auto Idle Stop system are available for inspection upon request. The problem has not yet been confirmed by a dealer, though I intend to bring it in for diagnosis. There were no warning lamps or messages before the failures occurred; the only symptom was the engine simply not restarting after an automatic idle stop.
I was at the red light and the car wouldn't come out of idle. The battery light came on and the i tried to turn the car off and it just keeps cycling. I had to open the door for the car to cut off and then restart the car. This is the 3rd time this has happened and almost resulted in me and my children being hit.
After driving the vehicle and stoppping for gas or to run a quick errand the van sometimes will not start, or gives difficulty starting. Slow to crank or turn over, sometimes has to be started multiple times before it will restart. It happens after the motor has been running. It never has issues first thing or the first time turning the car on for the day. The issues come once the motor has been run. -took the vehicle in to Honda dealer on 6/8/26 they recharged the battery. -7/9/26 took van into Honda dealer they replaced the battery. 8/15/26 van still having issues starting once engine warm. Dealership said starter is failing and replaced the starter.
Sometimes the engine wouldn't start. Sometimes the engine would be slow to start. Checked battery and nothing wrong with it. Took it to Honda and asked to look into common starter problem. They did say the starter was faulty and replaced it.
My van has an auto-stop feature that shuts the engine off at stop lights. This feature will now occasionally shut the car off, but then fail to restart it. We have stalled out at intersections with the van not restarting for up to a full minute. This is incredibly dangerous and needs to be addressed immediately
Starter is very weak when hot. 2 hour drive in summer heat and the van would not start after stopping at a gas station.
Vehicle with 37k miles. When the idle stop feature is activated at a stop, it causes the vehicle to stall requiring a restart. The starter occasionally does not work as well. Starter and battery was replaced at 12k and the issue has resurfaced. This poses a significant safety risk.
Numerous times since purchasing my van it has failed to start. At first it was just random at a stop light when I would forget to turn off the idle stop. Leaving me stuck at stop lights with a vehicle that won't turn on without multiple attempts. More recently it struggles to start after stopping to run errands or get gas or in drive thru lines. Having to depress the break pedal to the floor (much further than needed to even stop the car) and press and hold the on/off button while it chugs and attempts to start. The issue was able to be recreated by the dealer and they indicate that it is a starter issue but the part is on back order. Upon further discussion it appears that this isn't an unknown issue and that there is a current investigation into this issue. However, the service manager indicated to me that this isn't common and this was a "one off" incident.
Auto idle/stop system engages while sitting at a traffic signal as designed. When attempting to proceed, the engine fails to restart and all electrical components completely shut off for several minutes. All components stop working (information screen, gauges, hazard lights, and door locks are non-functional) and the vehicle is unable to turn on for several minutes. This creates an unreasonable safety risk for the occupants of the vehicle and for surrounding motorists when this failure occurs in active traffic lanes as the vehicle when it is reasonably expected for the vehicle to resume propulsion and with no ability to turn on hazard lights to warn approaching motorists of the vehicle's disabled status. The failure of the door locks during the event traps the occupants inside the vehicle, which we are in Florida so, hot summer days the internal temperatures can reach deadly levels within minutes with no way to escape. The vehicle was initially inspected by a manufacturer authorized dealer service department on 7/8/25 and the issue was dismissed. The vehicle was again inspected on 7/30/25 by the same service department and confirmed. A starter motor assembly and relays were replaced by the dealership and the vehicle returned to use on 8/4/25. Again, on 8/5/26 the vehicle exhibited the same safety defect while in an active traffic lane. The vehicle was returned to the same service department on 8/6/26 where it remains as the date of this report with no communication on resolution for the problem from the manufacturer. There were no warning lights or messages prior to the failure.
2025 Honda Odyssey with 21.5k miles on it. Pulled up to a stoplight after a 3 hour drive. Auto stop turned the van off. When the light turned green the van failed to restart. Put the vehicle in park, turned it off, waited a few seconds and attempted to re-start it. Van restarted but very sluggish, like the battery was dead. Pulled in and parked. Van started normal the rest of the day. Took it to the dealer 2 days later. They noted the battery was a little low but no codes and no explanation for why it failed to restart. They checked alternator and starter and claim they are both good.
Vehicles turns off when the brake is pressed and does not turn back on. The van has to be put into park and the start button has to be hit 2-3 times before it will restart. This has happened 3 distinctive times where it was difficult to restart. We try to disable the start/stop system each time we drive. It has left us stranded at traffic lights for up to 20 seconds trying to restart the van, impeding traffic at high speed interchanges. The van does eventually restart but each time it feels like it’s getting more difficult. This problem first appeared about 1 year after purchasing the van with about 23k miles on it and now has 26k miles. There are warnings that display because the vehicle is still in drive when it shuts off and it needs to be placed back into park to restart it. It occurs the most during a long drive on the highway. It can be very jerky when it restarts, perhaps slamming into gear. It is available for inspection and I plan to go to the Honda dealership soon for a scheduled oil change. I have not been there since the 18k mile oil change.
In approximately October 2025, while stopped at a traffic light, my 2025 Honda Odyssey's auto idle-stop system shut the engine off as designed. When I released the brake, the engine failed to restart. The vehicle remained disabled in active traffic for about one minute. After several attempts and shifting into Park, it finally restarted. There were no warning lamps or messages beforehand. This put me and others at risk because the vehicle was unexpectedly immobilized at an intersection and could have been struck from behind. An authorized Honda dealer diagnosed the starter as causing a slow/no-start condition and replaced it under warranty on October 9, 2025, at 21,211 miles (repair order #192362). The problem has recurred. I began noticing hesitant or slow restarts and normally disable auto idle-stop because I am afraid the vehicle may again fail to restart. On August 4, 2026, at 40,990 miles, the same Honda dealer diagnosed the starter as needing replacement again (repair order #203412). The battery passed its reserve-capacity test. The dealer documented a 0.600-volt ground-side drop, a 0.275-volt positive-side drop, and onboard voltage falling to approximately 7 volts during restart. Honda TechLine directed the dealer to replace the starter (TechLine case #5009355). The vehicle and current starter are available for inspection. The original starter was retained or disposed of by the dealer after the first repair. American Honda case #16533911 is open. No police or insurance representatives inspected the vehicle.
When the vehicle comes to an idle stop and brake is released, the vehicle shuts off and does not kick back on. Only solution in the moment to get the engine to restart is trying to start the car repeatedly until it comes back on. Vehicle has been looked at for this issue but they were unable to replicate the issue. Engine light will sometimes come on when this occurs. Other times the charging system light comes on, as well having multiple warning lights coming on at once. Causes a safety issue when it’s not restarting while in traffic. Issues started a few months after purchase. Took it into the dealer and they determined the throttle body needed to be replaced.
Incident Description: The vehicle entered an Auto Idle Stop event at a traffic light and stalled completely instead of restarting when the brake pedal was released. The red battery warning light illuminated, and the vehicle had to be shifted into Park and the ignition key cycled multiple times to eventually achieve a slow, sluggish crank and engine restart in active traffic. Another vehicle was almost going to hit me from behind since red light turned to green when this happened, and that driver from far behind was thinking that my vehicle will start moving and did not slow down. That driver started honking and yelling. It was scary since I had 3 small kids in my vehicle. Dealership Diagnostics: I dropped off the vehicle at a local Honda Dealership to get this checked. From the invoice/service document, I see this note: Cause: Took several attempts but was able to duplicate concern of when vehicle goes into auto start stop it will not always restart, will have to cycle key. Noticed when it did restart it is slow to crank. Battery tested good, and had good reserve voltage. Used tech line as a resource and found this issue is caused by starter not having enough voltage to properly engage auto stop start. rec replacing starter. Correction: Replaced starter.
The Auto idle stop feature fails to restart the car during a stop. This happens intermittently but requires one to fully put the car in park and restart the car. This issue has caused concerns as I was at a stop light with a long line and did not know how to recover until I tried to full shutdown, set the car to park, and restart.

My brand new vehicle continues to leave me stranded at stop lights because of the auto start stop system. Even though I have already taken it up to the dealership before and had it repaired. (There is a class action started over this)
While driving my 2025 Honda Odyssey, the Auto Idle Stop system shut off the engine at a stop as designed, but the engine failed to restart when I released the brake pedal. This left the vehicle stalled at an intersection. No warning lights appeared. This has occurred 6 times. Dealer was contacted; service is scheduled
The van is experiencing the auto stop-start defect causing major safety issues for my family. The car stalls randomly at stop signs and stoplights and is unable to be restarted quickly, creating a major traffic and safety hazard. The car often will not turn on at start up. The dealer stated that it needed a new starter. Then said that Honda would not replace the starter until a tech looked at it. Then after several weeks still had not moved forward getting a tech. Then said to bring the van in for them to keep until they could get a tech, and offered a small car without room for the kids as a loaner for the indefinite amount of time they want to keep the van. There were no warning lights when it has happened. This issue is already being investigate by the federal safety agency - Investigation Number EA25004. This is a known issue for Honda and I am unable to get a safe vehicle or get my vehicle fixed. Below, i have to choose a date for the incident, but this is ongoing and has happened on more dates that I can possibly log. It happens weekly, if not daily.
