   Several (more than 5) times over the past 2 months my car has had the same issue occur. The automatic Idle Stop feature was turned on and the engine was idling at a stop sign or red light. When I went to press on the gas to begin driving again, my engine would not restart and I received an error message. I was unable to change gears and had to manually turn off my engine, wait a few seconds and restart the engine, and then put back into drive. Again, this has happened several times over the past couple months. My safety was at risk because I was at risk of beging in an accident if the car behind me started to drive when the light turned green, not realizing I was stuck with an engine in idle mode, unable to drive my car.

   I’ll be at a red light and when it’s time to go the car is off and I have to put on the emergency lights until I get car on usually after three times of pressing the brake and pushing the start button. The car shuts off while idling at a red light and does not turn back on when brake is released.

   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.

   > 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.

   On September 25, 2026, I was stopped at a traffic light in my 2025 Honda Odyssey when the automatic idle stop activated. I was at a busy intersection with a line of cars behind me. When the light turned green, I took my foot off the brake and pressed the accelerator, but the vehicle shut off. I tried several times to restart the vehicle but was unsuccessful. It took several minutes before I was finally able to get the vehicle started again. During that time, I had a line of cars behind me waiting for me to move. Being stuck at a busy intersection with a vehicle that would not restart was very unsafe. I was concerned that a vehicle behind me could hit me because I was unable to move when the light changed. There were no warning lights or messages before this happened. This has never happened before. There was no accident or injury, and the vehicle is available for inspection. I have an appointment with a Honda dealership on October 9, 2026, to have the automatic idle stop failure investigated.

   The car's auto start stop shut off and did not restart. It took over a minute at a stop light of a busy intersection to get the car to restart. This has occurred multiple times now.

   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

    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.

    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.

    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.

    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.
