We were waiting at a busy stoplight and our vehicle shut itself off and put itself into park. We could not get it to start again so we were stuck in the middle of traffic.

The vehicle continues to shut off its engine at stops and is unable to restart. This has been occurring at an increased rate since I initially reported it last summer. Warnings come on the dash as it struggles to try to restart. Recently it has started to take a full light cycle to get it to restart. I have to turn the vehicle off and wait some time and try restarting it. I’ve notified the dealership ANTRIM HONDA and their service advisor said it’s a known issue but the starters are on national back order and there’s nothing they can do to help.

The Auto Idle Stop (AIS) does not work properly and is unsafe. When auto idle engages at a stop light, it is slow to restart, beeps and flashes the battery symbol, and sometimes fails to restart. On a more recent trip, when sitting on a freeway offramp waiting for the light to change with my entire family in the car, the vehicle completely failed to restart after AIS engaged. We were sitting ducks on the freeway and were having difficulties restarting the van. We had to go into Park, Drive, and press the start engine button several times for anything to happen. This issue has been going on for a few months. The battery has been checked and is in good working order, no issues reported. The last battery check occurred today 11/5/2026. I am going to input the date the vehicle completely failed to start, since that time, I have tried to remember to turn off the AIS feature when driving the vehicle. This is a new car and should not be experiencing this incredibly dangerous situation. 2025, Honda Odyssey Elite

When auto shut off enables at stop lights, sometimes the car goes into park and seems to turn lff and has an error message. It requires pushing the brake and manually starting the car by hitting the on button. There is risk to a rear end collision since it doesn’t happen until you take your foot off the break to start after stopping so creates risk of a rear collision if cars behind don’t noticed you are stopped. It has happened multiple times and seems to happen even more frequently in eco mode

When the auto idle system is forgotten to be not turned off the van will stall. We have had scary incidents where we have stalled at lights and have to restart the van one or more times to get it to drive. There is also problems with the van starting up in the first place. Sometimes when trying to turn on the van it takes a time or two to get it to turn on.

My 2025 Honda Odyssey failed to restart after the Auto Idle Stop system shut off the engine at a traffic light. I had to move to the side of the road and call a tow truck. This created a dangerous situation, and I am concerned about the safety of this vehicle. I respectfully request that the federal safety agency investigate this issue to determine whether other Honda Odyssey owners are experiencing the same problem.

The idle/stop function fails frequently at stop lights and stop signs. When it stops the engine it fails to restart and drains the battery. It began occurring very early on with the vehicle I’m guessing around 20,000 miles. I took it to the dealership while it was under warranty and they replaced the battery, and I believe the starter. It seemed to help for awhile but around 40,000 miles it started occurring again. I’ve been lucky to not be rear ended but drivers have had to go around me or sit through a stop light. There are no warning lights. I try to turn off the idle off button every time I start the vehicle. It is very unsafe and no longer under warranty. The dealership seemed like they didn’t know what was causing it last time and they had the van for over a week.

The Auto Idle feature has caused my car to stall multiple times. This is extremely dangerous because it always happens when I am in populated areas- sometimes at red lights and another time in stop/go highway traffic. My car is 1.5 years old and this keeps happening more and more frequently. I am very concerned that one of these times I am going to be rear ended because traffic starts to go, I let off the brake to drive and then my car stalls. I then have to turn my vehicle off completely and then back on to get it to not have issues. I do get a warning saying to depress the break and press the start button. Sometimes I get a red battery light on the dash.
