The vehicle completely stalled, we believe it’s related to the engine in reference to the idol on and off mechanism. We began to drive forward and the auto on off starter caused the car to completely shut down and freeze in an intersection.

Idle Stop Failure. This has occurred many times. Presents itself as: Failure to restart upon releasing the brake. Rough restart. Sometimes have to completely turn off car and restart.

My Odyssey has a no-restart issue related to Auto Idle Stop. Engineer did not restart at red light and I had to push the button twice. We were caught in traffic and was not safe.

The car stopped while driving in the middle of the street and would not turn off or on.

The vehicle experiences abnormal vibration and shaking felt from the rear during braking at moderate to highway speeds. The condition does not occur during steady driving and is isolated to braking events. An authorized dealership inspected the vehicle and documented rear brake rotor thickness variation but no repair was performed. The issue has continued and raises concerns about braking stability and safety, especially at higher speeds.

The contact owns a 2025 Honda Odyssey. The contact stated that while stopped at a traffic light, the contact released the brake pedal and depressed the accelerator pedal; however, the vehicle failed to respond. The contact believed that the failure was related to the gas saving feature. The vehicle then stalled, but was able to be restarted. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 11,390.

When the Auto Idle Stop is engaged, I have now had 3 instances of the engine completely stalling when at a stop. Not only has the engine stalled, but I have difficulty getting the engine to restart. It has been very scary, as it has left me disabled at busy intersections while I struggle to get my van to start so I can move and pray nobody hits me while I sit there. I've even had to open the driver's door to get the van to restart. We've made a habit of manually turning the auto idle stop feature off every time we drive it. This problem has not occurred when the feature is turned off. The first incident of this was several months ago, and I already took it to my local dealer but they couldn't replicate the issue and did nothing about it.

My van is a 25 Odyssey Elite with 18K miles. On several occasions, when I have been stopped at a stoplight and the idle function is activated, the vehicle doesn't auto restart and often it must ben put back into park and restarted. This has worked with a bit of effort. It typically is not just a push of the button but rather some sputtering, several attempts at pushing the ignition button and then and eventual start. Today I had it happen again and had a challenge getting it restarted and this time I noticed that the battery red light came on along with some other warning lights (I don't remember which ones as I was panicking to get going an not hold up the line of cars behind me.

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 feature. When I took my vehicle to the dealership, I was told my starter was already having issues despite the car having less than 10,000 miles on it. This ongoing problem has made me concerned for my safety and the reliability of my vehicle.
