At 10 AM on Saturday, October 10, 2026, I experienced an issue with my 2025 Odyssey Touring while stopped at a traffic light waiting to turn left. The auto start-stop feature failed after around 1-2 minutes when I was about to go forward. The car was automatically put in accessory mode and I had to power cycle the car (park, turn off, restart) in the middle of a green turn. Had hazards on. Thankfully, I got it restarted before the next green but this is not acceptable. Serious safety issue. I am concerned this will happen again, so this feature will stay disabled until addressed by Honda.

2025 Honda Odyssey. The auto idle-stop shuts the engine off at red lights as designed, but the engine intermittently fails to restart when the brake is released. Some days it happens, some days it does not; on occasion twice in one day. Restarting requires pressing the start button repeatedly. No warning lights appear before or during the failure. The vehicle is left stalled in active intersections when the light turns green, creating a risk of rear-end collision. The issue occurs only with auto idle-stop enabled.
I purchased a brand-new 2025 Honda Odyssey in June 2024. The vehicle currently has approximately 18,000 miles. The Auto Idle Stop system has repeatedly shut the engine off at traffic lights and failed to restart it. When this occurs, the engine does not crank, the dashboard remains illuminated, the radio and other accessories shut down, and the display instructs the driver to press the brake to start the engine. Pressing the brake and attempting to restart the vehicle does not work. The vehicle may remain disabled for several minutes before eventually restarting normally. This has happened multiple times. The vehicle has been taken to Honda dealerships twice specifically for this problem, but the technicians have been unable to duplicate the failure. On a separate oil-change visit, the battery tested low and was replaced. The restart failures have continued. Approximately two months ago, my wife experienced this failure while stopped at a traffic light. While the Odyssey was immobilized and unable to restart, a motorcycle struck the rear of the vehicle and fled the scene. The vehicle sustained damage. No police report was filed at the time. I am extremely concerned that this intermittent failure creates a serious safety hazard for my family and other motorists. I request that the federal safety agency investigate this recurring failure, including its potential connection to previously reported Honda Auto Idle Stop restart problems.
The idle auto stop is designed by default, multiple times the engine stopped in front of a red light and couldn’t start the engine right away. Sometimes need multiple times to restart the engine
My Honda Odyssey shuts the engine off at a stop under Auto Idle Stop and then fails to restart when I release the brake. I have to shift to Park and press the start button. This has happened at least 5 times, including today, while stopped at a traffic light at a busy intersection. The van was immobilized in active traffic. Extremely dangerous situation.
Auto Idle Stop feature wouldn't restart vehicle while at an intersection. The vehicle eventually restarted, but not without causing traffic disruption. It took the entire light cycle(red-> green -> red) for my wife to be able to manually(had to push the start button several times) for the car to eventually restart. Warning light on dash said something to the effect of "unable to engage "something"(wife cannot remember, she was panicking due to being stalled in the middle of the road) This not the firs time this has happened, and we have had it in for this before but the the dealership has not been able to find any issue to date. Honda factory also is aware of the issue(maybe for over a year now, but still has not found a fix)
The car stalls out/does not start back up when Idle Stop is used. This causes a risk for an accident as the vehicle does not more forward when it should. This now happens daily for the past month. This happened in the past with this same vehicle and the starter was replaced by the Honda Dealership Service Department. It is going into the Honda dealership Service Department on 10/5/2026.
On numerous occasions, the START/STOP idle system could not restart the engine. Happens often but not predictably.
My 2025 Honda Odyssey Elite has recurring, intermittent difficulty restarting after the Auto Idle Stop system shuts the engine off at a stop. I purchased the vehicle in December 2024, and it currently has approximately 37,000 miles. When attempting to restart, the engine sounds as though it is struggling to turn over. Most of the time it eventually restarts automatically, but on some occasions it fails to restart automatically and I must use the ENGINE START/STOP button. An intermittent dashboard message sometimes appears during these events but disappears before I can read it. The problem occurs even after long drives and sometimes appears worse after a long drive. The vehicle has also struggled to restart using the push button after being parked for approximately one to five minutes following driving. It typically starts normally otherwise. A Honda dealership previously replaced the starter to address this problem. The vehicle improved for a period after that repair, but the symptoms have returned. The underlying cause of the recurring problem has not been confirmed. Failure to restart after an automatic engine shutdown leaves the vehicle unable to proceed from a stop until the engine restarts, creating a risk of a collision in traffic. The problem remains unresolved. Please consider this report in connection with the federal safety agency investigation EA25004 concerning failure to restart after Auto Idle Stop.
The auto start/stop feature shuts my car off and doesnt start back up when I let off the brake pedal. It has done this 3 times while at a red light and its very dangerous getting stuck in the middle of the street with my kids in the car.
My car has stalled numerous times when it stops, and the engine goes into the fuel saving off mode. It stalls when I try to drive away as my foot comes off the brake. This has happened more times than I can count. In addition, as a side not I rented another 2025 Honda odyssey, and it also died when trying to go. The dealer has supposedly driven my vehicle when we bring it in but never has reproduced it according to them. They did admit that they knew about it but had no solution at present. There only response was to say to turn the engine shut off switch to disable it. There are warning lights after it dies but not before.
Several (more than 5) times over the past 2 months my car has had the same issue occur. The automatic Idle Stop feature was turned on and the engine was idling at a stop sign or red light. When I went to press on the gas to begin driving again, my engine would not restart and I received an error message. I was unable to change gears and had to manually turn off my engine, wait a few seconds and restart the engine, and then put back into drive. Again, this has happened several times over the past couple months. My safety was at risk because I was at risk of beging in an accident if the car behind me started to drive when the light turned green, not realizing I was stuck with an engine in idle mode, unable to drive my car.
I’ll be at a red light and when it’s time to go the car is off and I have to put on the emergency lights until I get car on usually after three times of pressing the brake and pushing the start button. The car shuts off while idling at a red light and does not turn back on when brake is released.
> While driving our Honda Odyssey, we have experienced a recurring and extremely serious safety issue involving the vehicle’s Auto Idle Stop/Auto Stop feature. When the vehicle comes to a stop at an intersection, the system automatically shuts the engine off as designed. However, on multiple occasions, when it is time to proceed, the vehicle has failed to restart. The engine remains off and we are unable to immediately get the vehicle restarted or move it out of the roadway. > > **This is not an isolated incident. This problem has occurred frequently and has recently begun occurring with increasing frequency.** We are extremely concerned that the condition is becoming progressively worse and that we cannot predict when the vehicle will fail to restart after the Auto Idle Stop system activates. > > During one particularly serious incident, the vehicle failed to restart while we were stopped at an intersection. When the traffic signal turned green, our Honda Odyssey remained disabled in the active traffic lane. We attempted to restart the vehicle but could not immediately get it running or move it to a safe location. > > This created an extremely dangerous situation. A vehicle approaching us from behind nearly rear-ended our stopped van. The approaching driver swerved at the last moment and thankfully avoided striking our vehicle, but subsequently crashed their own vehicle. Had that driver not been able to avoid us, we believe this could have resulted in a very serious rear-end collision, significant injuries, or fatalities. > > Because this problem has happened repeatedly and appears to be occurring more frequently, **we have also contacted the Honda dealership, Penske Honda on 96th Street in Indianapolis.
The car's auto start stop shut off and did not restart. It took over a minute at a stop light of a busy intersection to get the car to restart. This has occurred multiple times now.
Several dozen times now the vehicle’s engine shuts off at a stop via the auto engine stop system when depressing the brake. When releasing the break, the car engine doesn’t restart. It requires putting the car into park, turning off the car via the ignition button, and turning it back on. This has happened 5 times at a busy intersection, and people start honking. Now when it happens, I need to put the emergency blinkers on before starting the entire restart process. I try to press the auto engine shutoff button when I turn the car on so this doesn’t happen, but I often forget. There should be an easy way to disable this incredibly unsafe feature, considering we usually have young children passengers.
Engine won't start. This problem began as intermittent no start after driving for more than 30 minutes in hot weather. Such as stopping for fuel or a roadside rest on the interstate. It has progressed to intermittent no start in the mornings, or after work. Or after short drives for errands. Vehicle has been evaluated by the Honda Service Center. They stated they couldn't reproduce the problem, but it is a known problem. They also stated that there isn't any parts available. And there won't be any parts available until January 2027 or later. I asked what's my options, this car isn't reliable and it's going to leave my family stranded. The service center told us to not use AIS (Auto idle stop) We haven't used it since we bought it. No loaner, rental or other options. No replacement parts for 5-6 months isn't acceptable. This vehicle only has 20,000 miles and is 18 months old
With auto idle stop enabled, the engine frequently fails to restart upon brake release. To restart the engine, I have to turn the car off and back on again using the engine start button. This has happened many times at traffic lights if I forget to disable the auto idle stop. Twice in the last month I have almost been hit by the car behind. The Honda dealership was unable to recreate the issue. It is apparent that many other new model Honda Odysseys are also experiencing this same issue from an online search, leading me to suspect Honda has a hazardous design deficiency.
9/22/2026- the car idle stop failed to restart at a intersection. 9/23/2026- the car did not start after stopping to get gas. I have not taken it to the dealer yet. Will do it as soon as I get a chance. When the idle stop fails the car shift into parking and only the accessories are on.
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.
Multiple instances of the auto start not reengaging while stopped at intersection. Have to completely shut off and restart vehicle.
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
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 the federal safety agency 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.
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.
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 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.
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.
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
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 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.
