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.

My 2025 Honda Odyssey has repeatedly failed to automatically restart after the Auto Idle Stop system shuts the engine off while stopped at traffic lights or in stop-and-go highway traffic. The problem began approximately four months ago and is intermittent, occurring roughly once per week. When the problem occurs, the Auto Idle Stop system shuts the engine off normally while the driver is stopped with a foot on the brake. When the driver releases the brake, the engine does not restart as it should; instead, the vehicle automatically shifts into Park and the instrument panel displays “Accessory Mode” or similar wording. The driver must then press the brake pedal and push the engine start/stop button repeatedly to restart the vehicle. So far, the vehicle has eventually restarted each time, but it can take approximately 2–3 minutes and multiple attempts. This creates a significant safety hazard because the vehicle becomes disabled in an active traffic lane, including at busy intersections and in stop-and-go highway traffic, while the driver attempts to restart it.

The vehicle will slam on its brakes with nothing around it. This has happened more times than I can count now and has almost caused us to wreck on multiple occasions

This vehicle will randomly turn these features on and instead of keeping you in your lane pull you off the road, I have had to pull over to turn the vehicle off to get it to turn off

Would die at lights and so on, starter replaced and its started doing it again. Dies at lughts, stalls out at stops then will hesitate to start again and will throw itself forward making a clunky noise

The automatic door will not close. It will bounce back open like something is in the way when nothing is. You either have to turn that feature off and close it or you sit there hitting the button 40 times for it to finally decide to close. Has been happening for months and have brought it up to the dealership repeatedly. I have multiple videos of this issue

The transmission has been having issues since it had 10 miles on it, it locks at certain speeds and wont go higher than 35, it misfires at lights, it will randomly make clunking sounds when driving and you can feel the vehicle throw you forward, ive taken it in multiple times, we have multiple cases open with Honda and they will not respond but it doesnt give any lights so dealership says they cant do anything even though theyve said they have felt it

Vehicle auto engine stop engages at intersections. Car fails to restart when system is supposed to reengage. The vehicle then has to have ignition restarted causing unanticipated dangerous situations. There is no warning that the system will fail to reengage and the problem is intermittent. This has happened several different times causing dangerous traffic hazards.

My auto start-stop idle function is malfunctioning. When I stop at a traffic stop light or the car comes to a stop, the car completely stalls when pressing the accelerator to go forward. This is resulting in very confusing and chaotic situations in the middle of the road with cars behind me honking. I need to turn off the engine completely and then wait a few seconds and then restart the car before going again. This is creating hazardous conditions on the road for my family and other cars.

My wife had just got off of the Interstate in Raleigh, NC and pulled to a stop light and the Auto Idle shutoff took over and stopped the engine. When my wife took her foot off the brake the motor cut off and stalled the behind in traffic. It was supposed to start the engine but did not. It then displayed a transmission error and took a minute or so before the transmission reset and allowed her to restart the vehicle. An online research shows this is a common issue with the Honda odyssey. We contacted the dealership and they have refused to complete the repair. And stated it doesn’t affect our year model.

The vehicle experiences a sudden and complete engine stall while at a complete stop in traffic (such as a red light) due to a failure of the Auto Idle Stop (AIS) system. The engine shuts down smoothly as intended by the fuel-saving feature, but fails to restart when the brake pedal is released or the accelerator is pressed. The vehicle drops into a total shutdown state, requiring the driver to fully shift into Park, switch the ignition completely off, and manually press the Start button to restart the engine. No warning lights, error codes, or dashboard messages appear before, during, or after the failure. This creates a severe safety hazard by leaving the vehicle unexpectedly stranded and unresponsive in active intersections.

The Auto Idle Stop system intermittently fails to restart the engine after the system shuts the engine off while the vehicle is stopped. When this happens, the vehicle remains disabled and I have to completely restart the vehicle before I can continue driving. This has happened twice while stopped in highway traffic. On both occasions, traffic began moving while my vehicle failed to restart, creating an immediate crash risk and nearly resulting in collisions from vehicles behind me. The problem is intermittent. The vehicle has previously been brought to a Honda dealership for this concern, but the failure continues. I have contacted the dealership again and have also contacted the manufacturer regarding the issue. There were no consistent warning signs before the failure. The problem occurs after the Auto Idle Stop system activates. Because the vehicle may fail to restart unexpectedly in active traffic, I am concerned that the condition presents a serious safety risk to the occupants of the vehicle and surrounding motorists. The vehicle is available for inspection upon request. This condition appears consistent with NHTSA Engineering Analysis EA25-004 involving Auto Idle Stop no-restart complaints on Honda Odyssey vehicles.

The van got stuck in park after backing out of a parking lot. Changed to drive but gear shift back to park. Have to restarted the car twice. People were honking nonstop. This is not safe.

My 2025 Odyssey stalls. The engine will turn off when I am stopped and will take at least 2 retries to get the engine to turn over. Once I was at a stop light on an interstate off ramp when it stalled. Once I was at a stop sign when it stalled. Twice I have been unable to start it at a store. I will settle the brake & push the start button & nothing will happen. I will try again. I have to take my foot fully off the brake, wait a few seconds, & try the steps again. It eventually starts, but I'm afraid that someone will hit me and hurt my children or myself as I'm a sitting duck.

My vehicle has failed to restart numerous times at stoplights with the auto start engaged. It also failed once when it was disengaged. It also stalls to start on initial start quite often. Even when it is disengaged, upon stopping my vehicle makes a type of quiver in the engine that sounds like a stall or like it is about to cut off. It usually evens out after 5-10 seconds. I had people drive around me, in heavy traffic, after a major fail at a red light. I had an aggressive drive pass around me quickly at another incident at a smaller redlight intersection. I have had it cut off, with my family, over 50mls away from home. A dealership replaced my battery that was under warranty. I was told there were no other issues and to keep my auto start disengaged while driving. I'm not sure that is my safest option at this point. I am extremely concerned it will happen at an intersection and I will roll into traffic with my family.

On Tuesday, September 8, 2026 while sitting idle at a red light I had my foot on the brake and when the light turned green, I went to push on the gas and the van would not go, nearly causing the car behind me to rear end me because they figured I was going since it was a green light. I turned my hazard lights on, and there was a warning that appeared on the dash but I did not catch what it said in time. When I looked down, the car had put itself in park so I shut the van off and when I turned the van back on, there was a red battery light on the dash and it said “ to continue to drive depress brake pedal and push switch”. The van would not go into gear so I then had to call police (I was blocking a traffic lane) and a tow truck. The van is still at our local Honda dealer where it was purchased and to my knowledge has not been looked at-today is day three of the dealership having possession of the van. Also, on the same day-two stop lights previous to this it had a severe lag from brake to gas.
