2025 Honda Odyssey Owner Complaints

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.

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.

This car has on multiple occasions now just turned off the Enginee when stop at a stop light and the Enginee idle feature is on. It makes you restart the car when you are trying to go from a stop light this is dangerous and causes angry driver behind you. I took my one year old car to the Honda dealership and they said they couldn’t help. This is a safety issue. It’s happening more and more frequently

Incident

Component and availability: The engine fails to restart after Auto Idle Stop shuts it off and now also fails to start on normal starts. The failure involves the Auto Idle Stop system and the engine starting system. The vehicle is available for inspection on request. What happened and safety risk: On approximately 8/5, I was stopped at a stop sign with Auto Idle Stop engaged. The engine shut off as designed but did not restart when I released the brake, and the vehicle automatically shifted into Park. The start button would not restart the engine, the vehicle could not be shifted out of Park, and the button also would not turn the vehicle off. The vehicle was stranded in an active intersection, where other drivers had to go around it, until it eventually restarted after several tries. Since then we have turned off Auto Idle Stop on every drive, but the vehicle has now also failed to start on normal starts: 9/17, 9/18 and several others in the 8/5-9/17 period. The car would not crank and start, it would only start after several (3-5) tries. A vehicle that cannot be reliably started or restarted risks leaving the driver and passengers stranded in traffic or unsafe locations. Dealer confirmation: This car has been seen by the dealer previously (i.e., in summer 2025) with the same issue, and had battery and starter system replaced. However, the issue recurred after several months. This vehicle appears to fall within NHTSA investigation EA25004 (Auto Idle Stop failure to restart). Warning signs: No warning lamps or messages appeared before or during the failures; dashboard and interior lights worked normally throughout. The only earlier symptom was slow or rough engine restarts after Auto Idle Stop on hot days.

Incident

During auto idle stop (usually happens after more than 5 seconds in idle stop) the van will stall (put itself in park and engine turns off). Restarting takes approximately 30 seconds because the van will not turn back on right away no matter how many times the ignition/start button is pressed. I was advised by the dealership we purchased the van from, to allow it to happen more frequently so that it can be properly diagnosed so we have not been turning off the auto idle stop. But I feel this is a safety issue and should be addressed immediately.

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.

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 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.

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.

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
