> While driving our Honda Odyssey, we have experienced a recurring and extremely serious safety issue involving the vehicle’s Auto Idle Stop/Auto Stop feature. When the vehicle comes to a stop at an intersection, the system automatically shuts the engine off as designed. However, on multiple occasions, when it is time to proceed, the vehicle has failed to restart. The engine remains off and we are unable to immediately get the vehicle restarted or move it out of the roadway. > > **This is not an isolated incident. This problem has occurred frequently and has recently begun occurring with increasing frequency.** We are extremely concerned that the condition is becoming progressively worse and that we cannot predict when the vehicle will fail to restart after the Auto Idle Stop system activates. > > During one particularly serious incident, the vehicle failed to restart while we were stopped at an intersection. When the traffic signal turned green, our Honda Odyssey remained disabled in the active traffic lane. We attempted to restart the vehicle but could not immediately get it running or move it to a safe location. > > This created an extremely dangerous situation. A vehicle approaching us from behind nearly rear-ended our stopped van. The approaching driver swerved at the last moment and thankfully avoided striking our vehicle, but subsequently crashed their own vehicle. Had that driver not been able to avoid us, we believe this could have resulted in a very serious rear-end collision, significant injuries, or fatalities. > > Because this problem has happened repeatedly and appears to be occurring more frequently, **we have also contacted the Honda dealership, Penske Honda on 96th Street in Indianapolis.

ELECTRICAL SYSTEM
Vehicle intermittently failed to start. On one occasion following an Auto Idle Stop event, the restart was difficult (details in the "additional details" field). The vehicle did not restart as intended after disengaging the brake from Auto Idle Stop and manually restarted causing a several second delay in the roadway. On another occasion, after filling for gas, the engine cranked normally but did not start on the first attempt and started normally on the second attempt. Honda dealer diagnosed a defective starter and is replacing under warranty. Replacement starter is currently on national back order. Vehicle is included in NHTSA's active investigation (EA25004) regarding Odyssey starting/no-restart issues. General Guidelines responses: What component or system failed or malfunctioned, and is it available for inspection upon request? -Starter, available upon request until replaced by dealer How was your safety or the safety of others put at risk? -The delay in the roadway could have caused an accident (to me and others) when the vehicle failed to start as intended after the brake was disengaged Has the problem been reproduced or confirmed by a dealer or independent service center? -Dealer has confirmed there is an issue with the starter and will be replacing it under warranty when it is available from back order Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -Only the dealer Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -No prior warning. However, the vehicle does sound "rougher" when it cranks as opposed to my other vehicle now that I'm comparing the two. Restart issues first occurred within the last week.

Several dozen times now the vehicle’s engine shuts off at a stop via the auto engine stop system when depressing the brake. When releasing the break, the car engine doesn’t restart. It requires putting the car into park, turning off the car via the ignition button, and turning it back on. This has happened 5 times at a busy intersection, and people start honking. Now when it happens, I need to put the emergency blinkers on before starting the entire restart process. I try to press the auto engine shutoff button when I turn the car on so this doesn’t happen, but I often forget. There should be an easy way to disable this incredibly unsafe feature, considering we usually have young children passengers.

Engine won't start. This problem began as intermittent no start after driving for more than 30 minutes in hot weather. Such as stopping for fuel or a roadside rest on the interstate. It has progressed to intermittent no start in the mornings, or after work. Or after short drives for errands. Vehicle has been evaluated by the Honda Service Center. They stated they couldn't reproduce the problem, but it is a known problem. They also stated that there isn't any parts available. And there won't be any parts available until January 2027 or later. I asked what's my options, this car isn't reliable and it's going to leave my family stranded. The service center told us to not use AIS (Auto idle stop) We haven't used it since we bought it. No loaner, rental or other options. No replacement parts for 5-6 months isn't acceptable. This vehicle only has 20,000 miles and is 18 months old

ENGINE
With auto idle stop enabled, the engine frequently fails to restart upon brake release. To restart the engine, I have to turn the car off and back on again using the engine start button. This has happened many times at traffic lights if I forget to disable the auto idle stop. Twice in the last month I have almost been hit by the car behind. The Honda dealership was unable to recreate the issue. It is apparent that many other new model Honda Odysseys are also experiencing this same issue from an online search, leading me to suspect Honda has a hazardous design deficiency.

The Auto Idle Stop (AIS) failed to work properly for my wife when she was stopped at a stoplight. When she stopped at a stoplight the engine stopped. When she took her foot off the break and applied pressure on the gas pedal a warning of some sort showed on the screen where the speedometer is and the car failed to restart and move forward. This caused a hazard because the people behind her lurched forward because they assumed she would move forward once the light turned green. When our car failed to start she wasn't sure what to do to fix the problem so all the cars backed up behind her for a short time before she realized she needed to put our car in park, turn it off and then restart the engine. I will take my car in to the dealer as soon as possible. Until then we will have to disengage the auto stop function so prevent any further dangerous incidents.

The issue is that auto-idle intermittently does not restart. There have been multiple instances when the car has failed to restart after auto-idle, and most recently, this happened in the middle of the day on a very busy road at a red light. Stopped at the red light, the auto-idle turned the car off and it did not restart. I had to sit with the vehicle until I was able to get it restarted, which took about 4 minutes. Being on such a busy road, it caused a traffic backup with other vehicles having to move from behind me, causing others to swerve into other lanes and also drivers approaching to slam on brakes. As for warning light-there are none until the car stalls, and then every warning lights seems to come on. At that point, the warning lights are useless as the issue has already occurred without warning, causing an immediate safety risk to me, as well as drivers around me. We took the car to the dealer, which said they have had to repair multiple vehicles of the same make and model for this very issue. We had to pay for the full repair, as the car is recently out of the warranty coverage.

Auto stop start sometimes doesn't work even though battery was just replaced. Sitting at stoplight and when the car turns off with auto stop it does not turn on automatically when trying to move the car. Have to cycle the ignition and sometimes does not start.

9/22/2026- the car idle stop failed to restart at a intersection. 9/23/2026- the car did not start after stopping to get gas. I have not taken it to the dealer yet. Will do it as soon as I get a chance. When the idle stop fails the car shift into parking and only the accessories are on.

Problem with the idle auto off feature failing in traffic. Will be driving fine, come up to a stop (at a stoplight, stop sign, etc) and the engine will shut off as intended with auto off, but engine will then fail to restart/stall. Have to push the start button on/off several times before the engine will restart and we can continue driving, the delay leads to safety concerns and possibility of an accident with traffic behind us accelerating expecting our vehicle to be moving or other drivers not being able to predict our actions due to erratic start/stop. There is no option to permanently disable the auto start/stop. No warning or maintenance lights indicating there's a problem. This issue has happened 5-10 times since we purchased the vehicle late 2024. We have not taken the vehicle in to the dealer yet.

This car has on multiple occasions now just turned off the Enginee when stop at a stop light and the Enginee idle feature is on. It makes you restart the car when you are trying to go from a stop light this is dangerous and causes angry driver behind you. I took my one year old car to the Honda dealership and they said they couldn’t help. This is a safety issue. It’s happening more and more frequently

We have had several incidences occur with the auto idle stop system. It has failed to restart at stop lights/signs, car turns off and you must restart it. It happens unexpectedly without warning and you do not realize it until you press on the gas pedal. It causes panic and anxiety due to traffic behind you. It has also occurred in parking lots and in our driveway. One incident occurred on a trip, driving for a long distance and then pulling off the road to stop, the car turned off and took several tries to restart it. We thought we were going to have call a tow truck. Luckily we were off the road and it did finally restart. Scary rest of the long drive home. We have not noticed any warning lamps, messages or other symptoms prior to failure. We are extremely worried we will cause an accident if we leave the auto idle stop system on. We try to remember to always turn it off. This has been happening since we bought the car brand new. The auto dealership has checked it and cannot find a problem and are of no help. We noticed a forum on the internet where there is an ongoing investigation into the problem. Hopefully, something will be remedied to be able to fix it. Until then we have to remember to press the system off button.

When traveling to multiple destinations, upon attempting to start the van, it will not start. This is also the case with the auto start/stop program. The van's engine will stop at dangerous locations, such as a busy traffic light, or at any other stop where the engine turns off. There were no warning lights, but the van would only start if tried multiple times. This is incredibly dangerous and nerve-wracking.

During auto idle stop (usually happens after more than 5 seconds in idle stop) the van will stall (put itself in park and engine turns off). Restarting takes approximately 30 seconds because the van will not turn back on right away no matter how many times the ignition/start button is pressed. I was advised by the dealership we purchased the van from, to allow it to happen more frequently so that it can be properly diagnosed so we have not been turning off the auto idle stop. But I feel this is a safety issue and should be addressed immediately.

Component and availability: The engine fails to restart after Auto Idle Stop shuts it off and now also fails to start on normal starts. The failure involves the Auto Idle Stop system and the engine starting system. The vehicle is available for inspection on request. What happened and safety risk: On approximately 8/5, I was stopped at a stop sign with Auto Idle Stop engaged. The engine shut off as designed but did not restart when I released the brake, and the vehicle automatically shifted into Park. The start button would not restart the engine, the vehicle could not be shifted out of Park, and the button also would not turn the vehicle off. The vehicle was stranded in an active intersection, where other drivers had to go around it, until it eventually restarted after several tries. Since then we have turned off Auto Idle Stop on every drive, but the vehicle has now also failed to start on normal starts: 9/17, 9/18 and several others in the 8/5-9/17 period. The car would not crank and start, it would only start after several (3-5) tries. A vehicle that cannot be reliably started or restarted risks leaving the driver and passengers stranded in traffic or unsafe locations. Dealer confirmation: This car has been seen by the dealer previously (i.e., in summer 2025) with the same issue, and had battery and starter system replaced. However, the issue recurred after several months. This vehicle appears to fall within NHTSA investigation EA25004 (Auto Idle Stop failure to restart). Warning signs: No warning lamps or messages appeared before or during the failures; dashboard and interior lights worked normally throughout. The only earlier symptom was slow or rough engine restarts after Auto Idle Stop on hot days.

2025 Honda Odyssey - seems to have issue with auto-start auto-stop. Frequently, the minivan is unable to turn back on after it auto-turns off when stopped at a light or somewhere. Creates very dangerous situation because I am stuck as the driver, and the car is unresponsive. You have to put car in park, turn off the car, turn it back on, put in drive. People are honking and in one case we almost got hit because it was a stop around a turn and we couldn't move. I've checked for recall and it's not there. I'm taking it in to Honda dealer as soon as available. It's not everytime, but it's frequent. Probably happened 4 times in last two weeks.
