My 2025 Honda Oddessy with only about 31,000 has stalled in the last 2-3 months about 5 times at stop signs/stop lights. It throws itself in park and doesn't recognize that I'm pushing any buttons. On the dash it only says "press the brake" which I am doing. I called Victory City Honda in Michigan City, IN [XXX]) and arranged a diagnostics check on XXX. They said it wasn't throwing codes and didn't replicate when they test drove the vehicle. If I turn off the auto start/stop it doesn't seem to happen but if I forget to push this button each and every drive - it stalls and won't start for up to 10 minutes. Once we were parking at home and it would not allow us to shut the vehicle off. Upon research I found NHTSA investigation ID#XXX with the exact problem I am experiencing. I called my Honda dealor to report and they stated they are not able to do any software updates without a Honda recall. I have another appointment with them on XXX to check the battery and possibly the brake pedal sensor. Please help.

With idle start/stop enabled, there have been multiple occasions where the system has not restarted, causing my wife to almost get into an accident with my two young daughters in the car. Honda has looked at it on two occasions and claims there is no issue. However when researching this online, it has let me to find a NHTSA investigation, as well as hundreds of complaints about this are found online.

While the vehicle’s idle stop feature was engaged at a stop light, I took my foot off the brake to start moving again, but instead of starting again, the engine hard stopped and the van turned off completely. It told me to push the brake and start button to start it again but it took trying that several times and eventually holding the brake and start button down before it actually turned back on. Meanwhile, drivers stuck behind me were becoming increasingly irate and people were trying to get around me, despite heavy traffic. This is the second time it’s happened to me in this car. The first was about a month ago.

The two most recent incidents occurred on XXX. During one incident, we were stopped at a red light on a road with a 55-mph speed limit. The vehicle shut off and did not restart normally when traffic began moving. We were left immobilized in an active traffic lane while vehicles approached and passed us at approximately 55 mph. We had difficulty getting the vehicle restarted and moving again. This presents a serious rear-end collision risk because approaching drivers expect traffic to move when the light changes. Four children regularly ride in this vehicle, and we do not believe it is safe to continue driving. We contacted the Honda dealership again after the battery replacement failed to correct the problem. We were told that unless technicians could duplicate the issue, there was nothing further they could do. Because the failure is intermittent, we cannot predict when it will occur, but it has happened approximately 10 times and has continued after Honda’s attempted repair. We also opened a case with American Honda Motor Co., Inc. Honda case number: XXX VIN: [XXX] Vehicle: 2025 Honda Odyssey Approximate mileage at most recent incident: 15000 We are reporting this because the vehicle can unexpectedly leave our family stranded in an active traffic lane and unable to move out of the path of approaching traffic.

Our 2025 Honda Odyssey has repeatedly shut off or failed to restart while stopped. This has occurred approximately 10 times. The vehicle was previously taken to an authorized Honda dealership for this issue. The dealership diagnosed the battery as the cause and replaced it, but the same problem continued afterward.

After AIS engaged, the engine wouldn’t come back on. This has been at intersections, etc where it was dangerous to have no engine. It is ridiculous that the feature has not been removed after problems going back to the 2018 model. All to game an emission standard. Shameful.

2025 Honda Odyssey with approximately 22,000 miles. On multiple occasions while stopped at traffic lights or stop signs, the vehicle's Auto Idle Stop feature shut the engine off normally. When I attempted to accelerate, the engine failed to restart, leaving the vehicle disabled in the travel lane. The battery warning light illuminated, and on one earlier occurrence I believe a "Shift to Park" message may also have appeared. I was able to restart the vehicle by pressing the Start button, shifting back into Drive, and continuing normally. The most recent incident occurred while stopped at a traffic light. When the light turned green and I pressed the accelerator, the vehicle did not restart or move. I had to manually restart the engine while stopped in the intersection before I could proceed. This created a safety concern because the vehicle unexpectedly became disabled in active traffic. The vehicle has never exhibited difficulty starting during normal operation, either when cold or warm. The problem has only occurred after the Auto Idle Stop system shut the engine off at a stop. The vehicle has not yet been inspected by a Honda dealer, but an appointment will be scheduled.

2025 Honda Odyssey. When the auto start/stop engaged, the engine failed to turn back on when the brake was released. It left my family stranded at a stoplight for multiple minutes before my wife could get it going again. After going rounds with the dealership and Honda not being able to 'recreate the problem', they finally put in a new starter and the van worked for the next year. Fast forward one year later and it did the same thing. Now the dealership cannot recreate it again, and I am concerned for the safety of my wife and kids. Brand new vehicle should not do this and Honda is not doing anything to rectify the situation. I have read there are over 2 million complaints on this issue on this website but don't understand how a recall has not been implemented.
