2025 Honda Odyssey complaints

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.

When car stopped at light, engine will turn off and go into park and will not start again unless the car is turned off completely, wait a few minutes and then restart the car. This has been happening since 2/2026 and reported Ed Voyles Honda Dealership twice and this was not identified. Their action in the receipt attached below.

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 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 NHTSA investigation EA25004 concerning failure to restart after Auto Idle Stop.

On numerous occasions, the START/STOP idle system could not restart the engine. Happens often but not predictably.

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.

Idle Stop system - NHTSA EA 25004 My 2025 Odyssey fails its auto-restart from a stoplight, stumbles, and then has a very rough secondary start.

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.

On September 25, 2026, I was stopped at a traffic light in my 2025 Honda Odyssey when the automatic idle stop activated. I was at a busy intersection with a line of cars behind me. When the light turned green, I took my foot off the brake and pressed the accelerator, but the vehicle shut off. I tried several times to restart the vehicle but was unsuccessful. It took several minutes before I was finally able to get the vehicle started again. During that time, I had a line of cars behind me waiting for me to move. Being stuck at a busy intersection with a vehicle that would not restart was very unsafe. I was concerned that a vehicle behind me could hit me because I was unable to move when the light changed. There were no warning lights or messages before this happened. This has never happened before. There was no accident or injury, and the vehicle is available for inspection. I have an appointment with a Honda dealership on October 9, 2026, to have the automatic idle stop failure investigated.

> 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

Vehicle intermittently failed to start. On one occasion following an Auto Idle Stop event, the restart was difficult (details in the "additional details" field). The vehicle did not restart as intended after disengaging the brake from Auto Idle Stop and manually restarted causing a several second delay in the roadway. On another occasion, after filling for gas, the engine cranked normally but did not start on the first attempt and started normally on the second attempt. Honda dealer diagnosed a defective starter and is replacing under warranty. Replacement starter is currently on national back order. Vehicle is included in NHTSA's active investigation (EA25004) regarding Odyssey starting/no-restart issues. General Guidelines responses: What component or system failed or malfunctioned, and is it available for inspection upon request? -Starter, available upon request until replaced by dealer How was your safety or the safety of others put at risk? -The delay in the roadway could have caused an accident (to me and others) when the vehicle failed to start as intended after the brake was disengaged Has the problem been reproduced or confirmed by a dealer or independent service center? -Dealer has confirmed there is an issue with the starter and will be replacing it under warranty when it is available from back order Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -Only the dealer Were there any warning lamps, messages o

Drove over railroad tracks and the seat belts locked up on the driver and passenger. Smelled smoke right after.

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.

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.

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.

The Auto Idle Stop (AIS) failed to work properly for my wife when she was stopped at a stoplight. When she stopped at a stoplight the engine stopped. When she took her foot off the break and applied pressure on the gas pedal a warning of some sort showed on the screen where the speedometer is and the car failed to restart and move forward. This caused a hazard because the people behind her lurched forward because they assumed she would move forward once the light turned green. When our car failed to start she wasn't sure what to do to fix the problem so all the cars backed up behind her for a short time before she realized she needed to put our car in park, turn it off and then restart the engine. I will take my car in to the dealer as soon as possible. Until then we will have to disengage the auto stop function so prevent any further dangerous incidents.

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.

Auto stop start sometimes doesn't work even though battery was just replaced. Sitting at stoplight and when the car turns off with auto stop it does not turn on automatically when trying to move the car. Have to cycle the ignition and sometimes does not start.

2025 Honda Odyssey experienced an Auto Idle Stop no-restart condition. While stopped at a traffic light, the Auto Idle Stop system shut the engine off, but the engine failed to restart when attempting to proceed. The vehicle was disabled at an intersection, creating a potential safety hazard.

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.

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.

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

Multiple instances of the auto start not reengaging while stopped at intersection. Have to completely shut off and restart vehicle.

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.

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.

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.

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).

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 start stop malfunctioned. This put my family at risk of being rearended when others were trying to move at a green light and I was stalled.

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

Screen wont turn on, it just stays black, sometimes it will start to work sometimes it doesnt without the car being turned off and turned back on. Apple and android play dont work always, it just randomly decides to work sometimes

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.

.Auto off feature malfunctioned in traffic light .The vehicle's engine powered off while resting at stop light and the brake pedal was pressed .When the light turned green, lifted the foot off the brake pedal. The vehicle automatically went into park mode and locked itself. .The cars behind me went honking as it is a single lane road forming a massive line, since my vehicle stalled. .Had to turn the power off the vehicle and turn it back on, in the middle of the road while blocking everyone else behind me. .Issue occurs frequently

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.

The contact owns a 2025 Honda Odyssey. The contact stated that while coming to a complete stop at a red light or a stop sign, the vehicle stalled and shut off unintendedly. There was no warning light. The vehicle was restarted. The manufacturer was notified of the failure and stated that there was an ongoing investigation associated with the failure. The vehicle was not repaired.

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.

The contact owns a 2025 Honda Odyssey. The contact stated that while at a complete stop in traffic, the Auto START/STOP system failed to restart the vehicle on several occasions, and the vehicle was manually restarted. The contact stated that the failure had become more frequent and posed a safety risk for the family. The manufacturer, American Honda, was notified of the failure by phone, and the contact was provided a case number and referred to a dealer to have the vehicle repaired under warranty. The failure mileage was approximately 12,000.
