2025 Honda Odyssey complaints

The idle restart function causes the van to shut off completely when at stop lights in heavy traffic. It does not immediately restart and we have to sit in traffic while folk are honking at us to go. It doesn’t do this every time, but has happened 3 times in the last 3 months.

The auto idle system shuts off the vehicle completely at a stoplight or intersection and fails to restart when you release the brake. The vehicle is stuck in traffic and doesn’t restart for a few minutes mine had to be jumped started this THIRD time it happened. This created a hazardous safety condition for my family in which kids are always traveling. The dealer has not provided solution. Concerned this can cause a fatality because I can get rear ended.

I drove my kids 5 miles to school and was on my way back home going thru a school zone with a stop sign. As I stopped at a 4 way stop car went into idle and I went to proceed and car stalled and automatically went into park. I had to wave people around me. Luckily I was able to still put on hazards. The battery light came on, but I was unable to restart my car after several attempts. I opened my door to wave on more people and when I tried to start my car again it finally started. I am so luckily I wasn't at a busy intersection and took a different route home and lucky my kids weren't in the back either. This was very scary and am now worried for it happening again.

My vehicle has been failing to restart at stoplights after the auto start/shutoff turns off the vehicle. Instances where it does start, the starter frequently struggles to kick the engine over and when it does fire the vehicle jerks forward before driving.

Auto Idle Stop malfunction-- it happened twice during my travel (1)[XXX] , around 7pm. The car stalled and failed to restart at a local street of Hasbrouck Heights, NJ after signal turned green; (2) [XXX] around noon. The same problem happened at a [XXX] of Goshen, NY when a semi track was behind me. I reported to NHTSA immediately after the 2nd incident, but I cannot find a confirmation number before going to my dealer, so I re-file the complaint. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The idle stop function failed to restart the vehicle while in traffic at a red light. The vehicle was in traffic on a state highway and was unable to restart without shutting the vehicle off and on again. The problem has happened frequently the past few weeks to where I was able to reproduce and record the incident. The battery light appeared before shutting off the car with the push button on/off.

Engine failed to restart after AutoStop function engaged at a red light. We were stranded and had to manually restart the car, which took long enough to figure out that we were stranded in traffic for a bit.

I am experiencing a serious and recurring safety issue involving the engine unexpectedly completely shutting off while the vehicle is being driven and separately, the engine intermittently failing to start after the vehicle has been parked. 1.The engine unexpectedly and spontaneously shuts off when the vehicle is stopped or slowing down, including at stop signs, traffic lights, and during traffic slowdowns. These events occur without warning or notice, and the vehicle does not reliably restart immediately. In nearly all instances, the engine has failed to restart for several minutes despite multiple attempts. This creates an extremely dangerous situation. When the engine shuts off unexpectedly in traffic, I am concerned that drivers behind me will not realize that my vehicle is experiencing a malfunction and may collide with my vehicle before I am able to restart it and safely move. These incidents cause me significant fear and stress each time they occur. I am not certain whether the vehicle’s Auto Start/Stop system is involved in these incidents or whether another component or system is malfunctioning. I am requesting that Honda and the dealership fully diagnose the cause rather than assuming that the behavior is normal operation of the Auto Start/Stop system. 2.Separately from the engine shutting off while driving, the vehicle also randomly and spontaneously fails to start after it has been parked. I have documented some of these incidents by video, including instances in

The contact owns a 2025 Honda Odyssey. The contact stated that while at a complete stop in traffic, the idle stop system failed to restart the vehicle, nearly causing the vehicle to be rear-ended. The vehicle was restarted after several attempts. The check engine and battery warning lights were illuminated. The vehicle was taken to a dealer and the battery was replaced; however, the failure recurred while attempting to start the vehicle at the residence. The vehicle was restarted after several attempts with the same warning lights illuminated. The vehicle was taken back to the dealer, where it was determined that the failure might be associated with the starter; however, the contact was informed that no further repairs would be performed until the dealer received a service bulletin from the manufacturer. The failure mileage was approximately 19,000.

Vehicle restarted itself at a traffic stop to. Vehicle stalled at another traffic stop. Both occurred on the same single day drive.

It was approximately 8:45 pm at night. I was sitting in my 2025 Honda Odyssey stopped at a red light with my foot on the brake. There were no other cars in front or behind me. It was a long light so the car engine stopped as it usually does due to its auto start-stop system to conserve gas (although electricity in the car remained on). However, when the light turned green, I took my foot off the brake and pressed the accelerator. At that moment, the entire car shut off unexpectedly, including all lights, electricity, etc. It appeared to be a "normal" shutdown as the "check rear passenger seats" indicator flashed before the car turned off (this is expected in a normal shutdown since we have a carseat in the rear seat). Fearful of being rear-ended at night, I quickly pressed the brake and hit the power button (the typical process for turning the car on). Thankfully this worked and the car restarted as normal. It took about 15 seconds for the car to power on such that I could shift the car into Drive and begin driving as normal. After that I proceeded to drive a further 20 minutes on highway + rural roads + stop lights and nothing else happened. - I do not know which component failed, but I suspect it was the starter as the car failed to restart after the auto-start stop system was engaged. - My safety was put at risk as the car was at a traffic light and turned off when I attempted to drive it when the light turned green. This meant my car was sitting in the dark with no lights

The vehicle experienced multiple sudden engine stalls while driving in traffic. Specifically, the engine shut off unexpectedly and the transmission automatically shifted into Park (P) while on the road, leaving the vehicle immobilized and unable to be manually shifted out of P. Restarting the vehicle was extremely difficult, which created a severe safety hazard and nearly caused a rear-end collision. The vehicle was inspected and confirmed by an authorized Honda dealer that the starter failed. The starter has since been replaced. The failed component is available for inspection upon request.

Vehicle stalls at stop lights when the air conditioner is on when idle stop is engaged.

For several weeks, my 2025 Honda Odyssey, with approximately 30,000 miles, had been jerking while being driven. An independent mechanic believed the problem might be transmission-related. I brought the vehicle to an authorized Honda dealership, reported the jerking and specifically stated that I suspected a transmission problem. The dealership recommended and performed a transmission-fluid service. On August 24, 2026, at approximately 4:00 p.m., my wife was driving on the New Jersey Turnpike with our children when the vehicle suddenly jerked and behaved as though the transmission was attempting to engage reverse while the vehicle was moving forward. This created an immediate loss of predictable vehicle control and nearly caused an accident. My wife managed to pull into a parking lot. The vehicle then would not move in reverse and displayed a transmission-system warning. The vehicle was returned to the authorized Honda dealership. The dealership subsequently determined that the transmission required replacement, and it is currently being replaced under warranty. No collision or physical injury occurred, but this sudden transmission malfunction placed my wife, our children and other motorists at serious risk. The vehicle is currently at the dealership, and the failed transmission may be available through the dealer or manufacturer. I am requesting that NHTSA investigate whether this is a safety defect affecting the transmission or powertrain in the 2025 Honda Odyssey.

The vehicle comes equipped with “Auto off/on” at stoplights the vehicle will turn itself off to preserve fuel and is supposed to turn back on. Instead the vehicle dies in the middle of the road. I have to turn vehicle back to off and hope it starts back up. When it does finally start, it’s a slow start, it struggles. There’s been two incidents where it had to be jumped in the middle of the road/ intersection. Honda has confirmed it is a bad started. The vehicle is a 2025. There is no reason why the starter should be bad and there is no recalls on this and I’m not the only person with this van that is having the same issue. There needs to be an investigation in this matter.

When I was at the set of lights my vehicle put itself in park and refused to go back in drive. The dashboard started to flash "shift to park" cars were honking at us people we screaming because we weren't driving when the light turned green. But my car refused to go back into drive. I had to shut it off and turn it back on. I had all my kids (5) in the car. I brought it to the dealership and they said that there was no code recorded. And because of that they couldn't do anything about it. Almost as if it didn't happen. Then it has recently happened two more times. I'm bringing my vehicle back in to the dealership, but they told me if it didn't record a code then they couldn't really do anything about it. It was of the scariest things to ever happen. 21

The Auto Idle-Stop system is causing the vehicle to stall at stop signs, requiring a full shift into Park, engine turnoff and turn to restart to get moving again. This has happened two times in four days

2025 Honda Odyssey Elite. Approximately 12,000 miles. Vehicle has experienced 4–5 instances where Auto Idle Stop engages while stopped and the engine fails to restart. Vehicle cannot immediately be restarted with the push-button ignition and must be completely shut down before it will restart. Battery was replaced by Honda, but the condition is ongoing. Vehicle can and has become disabled at an intersections and traffic lights creating a potential collision hazard.

Engine failed to restart after turning off at idle at a stop. When releasing the brake the engine tried to turn on but stalled out. It is available for inspection upon request. No major safety concern, traffic behind the vehicle was prohibited from moving until the vehicle could be restarted. The failure has not been reproduced by a dealer or service center, or inspected by anyone else. There were no warning lights but after the failure a message displayed saying “To continue to drive, depress brake pedal and push switch”. The failure first appeared after 10,000 miles and occurred between 5-10 times since then.

Vehicle was using an off ramp and shutdown in the middle of a lane. It was 10:00pm and all systems were shutdown, including lights. Vehicle refused to restart and could not be placed in neutral, the vehicle could not be removed from the interstate off ramp. This issue has been brought to the attention of Honda, the started assembly was replaced on March 5, 2026. This vehicle has been delivered to Honda for similar electrical/starter issues 4 times since October 27, 2025. The first report was filed with Honda on October 27, 2025 with all lights on dashboard lit when vehicle was active. Had to wait until a tow truck arrived before vehicle could be safely removed from the scene.

Came to a stop at traffic light. Vehicle shifted into park. I was unable to put it back into drive. I shut engine off. After two tries, I was about to start engine again and was able to shift into drive. Incident happened again when I stopped at another traffic light about 2 miles later. Had to restart vehicle in order to enable drive mode.

My 2025 Honda Odyssey shut off in Auto Idle Stop while at a busy intersection. The car was unresponsive and would not engage the motor. After five minutes of trying to turn the car off and on, it eventually restarted and the motor came back to life. This issue put me at great risk of bodily harm. Given the fact the car was unresponsive in such a surprising way, I was very lucky not to have cars crash into me from behind as they few by for the 5 minutes I was stranded. This is the first instance and has not been reproduced as I am too worried to drive the car now. No inspection of the vehicle has been completed as this incident just occurred. No waring light prior to the incident, but the battery warring light did come on while the car shut off and unresponsive.

Engine fails to restart after auto off.

My van will stall at red-lights. It started three weeks ago. The car is a year and a half old. The auto- idle stop system is activated. We stop at a red light. Car stops. When we go to start car dings and thankfully has started 3 times. This time, the car made a ding and did not re-start. I was stuck at a now green light and couldn't move. The dash flashed hit the brake to re-start. I did numerous times. I couldn't get the car to switch to park or drive. I tried switching the car on and off and couldn't get it restarted. I was disabled for about 2 minutes before it kicked back on. My kids were in the car and this scared me.

Our 2025 Honda Odyssey Touring has repeatedly stalled or nearly stalled while driving. Of at least three dealer visits, the stalling issue was first formally documented on XXX, when we reported the engine shutting off twice while driving and the brake warning light activating twice. DTC 15477 ("failing starter") was recorded, and the starter was replaced. XXX, my [XXX] daughter was driving alone when the van lost power at a red light and would not respond to the accelerator once the light turned green. She was unable to shift gears or shut off the engine, and the van remained unresponsive in live traffic for several minutes before power returned on its own. A bystander helped restart the vehicle and move it to safety. I believe this defect is the subject of open NHTSA Engineering Analysis EA25004 (opened XXX), covering 2018–2025 Odyssey and related Honda/Acura models for Auto Idle Stop failing to restart after a stop. On XXX, the dealer confirmed the software was current, the battery was healthy, and replaced both relays, completing every step of Honda's documented repair bulletin. Hours later, on the drive home at 27,942 miles, the van stalled again at a stoplight. The dashboard instructed the driver to depress the brake and press the switch to continue driving. The driver powered the vehicle off and restarted it to regain control. Video of this incident: [XXX]. Dates of incidents: XXX – Two engine shut-off events and two brake warning light events reported; starter replaced

I am filing a safety complaint regarding a recurring, severe defect involving the 2025 Honda Odyssey's starter motor and the factory-installed Auto Idle-Stop (idle-stop) system.While driving, the vehicle's Auto Idle-Stop system engaged as designed when coming to a complete stop in traffic. However, when trying to accelerate, the vehicle failed to restart automatically. The engine completely stalled out on an active roadway. Attempts to manually override the system and restart the vehicle using the ignition button failed completely, resulting in an immediate and dangerous loss of propulsion.This defect presents a severe and immediate traffic hazard, as it unexpectedly leaves the vehicle completely disabled and stranded in active lanes of traffic. It strips the driver of the ability to clear the roadway to safety, significantly increasing the risk of a rear-end collision. Multiple occupants, including passengers in the rear seats, were exposed to extreme danger due to this sudden propulsion failure.Despite bringing the vehicle to an authorized Honda dealership, the manufacturer has failed to provide a permanent safety remedy. Also Honda corporate has deny warranty replacement for the starter that’s causing the issue.

Starter failure due to heat. Vehicle has failed to restart several times while stopped in traffic and at a traffic light due to the Auto Idle Stop function.

Engine failed to restart during Auto Idle Stop event. Nearly created an accident.

The vehicle experiences sudden, intermittent engine stalling while idling (either when coming to a stop at traffic lights or while idling in traffic). The engine shuts down completely and fails to automatically restart via the Auto Idle-Stop feature, forcing the driver to manually cycle the ignition or shift to Park to restart. This has happened multiple times since I bought the car at Stevens Creek Honda in September 2025 and have taken it to get it service at Livermore Honda in November 2025 and again in August 2026. The dealer has been notified but the defect remains unresolved, presenting an immediate safety risk of being rear-ended in active traffic due to sudden loss of propulsion.

5 times since July 2026 the vehicle 2025 Honda Odyssey fills with the smell of gas. The smell fills the entire garage. After the 4th incident, it was brought to the dealership on 8/18/2026, however they were unable to reproduce the issue smell. They stated the EVAP system was function and at the time there were no obvious leaks. Despite it being a known issue, there are no recall or repairs per the dealership. They stated that Honda is apparently aware and are "investigating." The smell recurred today and was immediately brought to the dealership since the problems was not reproduced when previously in their possession. It was noted by multiple staff member but since there is no known fix, there was nothing the dealership could do. They are aware of several other Honda Odysseys with this issue in the same area. I was instructed not to park the vehicle in the garage which makes me concerned for mine and my family's safety. The smell can be very overwhelming and makes me lightheaded.

After stopping at a red light the engine auto stopped and would not restart after releasing the brake. After 20 minutes of trying to turn the vehicle on/off it finally restarted. Serious safety concern since it was a busy road and the vehicle couldn’t be put into neutral to push it out of the lane. The vehicle is under 20,000 miles and in the warranty period. I haven’t taken it to the dealership to determine the issue however they did say there are no service bulletins for this issue. This is the first time it has happened but I have since turned off the auto start/stop before every drive in fear that it will cause a crash in the future.

My car, 2025 Honda Odyssey intermittently develops a raw gasoline odor inside the passenger compartment, particularly when traveling over bumps/rough pavement. Honda dealer inspected the vehicle and could not identify a leak or reproduce the problem.

While driving our 2025 Honda Odyssey, my wife came to a complete stop at a red traffic light. The vehicle’s Auto Idle Stop feature was enabled, as it is by default each time the vehicle is started. When the light turned green and she attempted to accelerate, the vehicle would not move. The engine appeared to be running/revving when she pressed the accelerator, but the vehicle remained stationary as though the brake was still engaged. A message appeared on the instrument panel instructing her to depress the brake pedal and press the start/stop button. Initially, we believed the electronic parking brake might have been engaged, so she attempted to disengage it, but this did not resolve the problem. She was stuck in an active traffic lane at an intersection and unable to move the vehicle, creating a significant safety concern. Another person advised her to completely turn the vehicle off, wait approximately 10 seconds, and restart it. After doing so, the vehicle operated normally again. After this incident, I learned that NHTSA is already investigating Auto Idle Stop/no-restart complaints involving Honda vehicles, including 2025 Honda Odysseys, under Engineering Analysis EA25-004. I also learned that Honda has previously communicated with dealers regarding Auto Idle Stop no-restart incidents involving 2023–2025 Odysseys. This was an extremely concerning failure because the vehicle unexpectedly became immobilized at a traffic light and could not be driven until it was shut down a

While waiting at a stop light, the engine turned off and the vehicle forced itself into park. Taking my foot off the brake, had no effect. I was not able to put the vehicle back into drive. I had to shut off the engine and restart it in order to drive again. Of note, the AC and carplay were running at the time of the engine failure. No warning lights appeared. Cars behind me were honking at me. I have an appointment scheduled with the dealership to assess the auto-idle function.

Vehicle turns off unexpectantly at red lights/intersections when auto idle engages and will not restart automatically. It takes 1 to 2 minutes for the vehicle to restart. There is no predicting when the issue occurs. Causes vehicle to be immobile in busy and congested intersections which results in safety issues to us and oncoming traffic. There is a potential for a head on or T-bone collision when this happens. We've had starter replaced before at 22,000 miles and now we have to do it again at 36,000 miles. The Honda dealer said he sees this issue twice a week so we aren't the only ones. To my knowledge, Honda has yet to come out with a permanent repair.

My car slammed on the brakes on its own. I was almost rear ended. I was going 45-50 miles an hour. I think it saw a shadow. Previously it has alerted me to brake because of shadows. This is the first time it braked hard on its own.

At a stop light and in traffic several times the vehicle has failed to restart when stopping for the idle start/stop. The vehicle will not immediately restart and takes several minutes, leaving me idle in the middle of traffic. The vehicle has been to the dealership several times for repair however I'm still experiencing this issue. This is a serious safety concern for my family.

Starter issue both during idle start/stop mode and going from off to on. Owned for about 20mos and happened first maybe 6mos ago and has happened a dozen times since then. So dangerous! We have had idle start freeze at a green light and are worried we’ll get hit. Sister in law has the same problem with hers. This needs to be fixed immediately!

When the engine is hot, the car hesitates to start for a couple seconds. Occurs on really hot days especially after stopping and starting the engine such as after getting gas or on idle stop at a redlight. The motor starter has been replaced by Honda to a new one but the issue can re-occur as the part being replaced is the same with the same build and will likely fail again in hot conditions.

The contact owns a 2025 Honda Odyssey. The contact stated that while sitting at a traffic light, with the Auto START/STOP feature engaged, the vehicle completely shut off. The contact was able to restart the vehicle after several attempts. The failure was a recurring failure. The battery was replaced; however, the failure persisted. The contact associated the failure with NHTSA Action Number: EA25004 (Engine and Engine Cooling). The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

While at a stop light on a major road, the vehicles auto start stop engaged. Upon the light turning green, I released the brake and vehicle failed to restart. The vehicle put itself into park and flashed a warning message "problem detected....." . I pressed the start button, and at first the vehicle failed to start, making a clicking sound, consistent with a dead battery or starter. I had to press the start button 4 times before the vehicle restarted and I could proceed. I was extremely concerned as I had my wife and three kids in the car, unable to move forward on a major roadway. I have an appointment at the dealer for this Friday.

I was at the red light and the car wouldn't come out of idle. The battery light came on and the i tried to turn the car off and it just keeps cycling. I had to open the door for the car to cut off and then restart the car. This is the 3rd time this has happened and almost resulted in me and my children being hit.

While stopped at a red light or intersection, the vehicle's Auto Idle Stop feature engages and shuts off the engine as designed. However, on multiple occasions, the engine has failed to automatically restart when the brake pedal is released. The vehicle remains stalled and unresponsive in the middle of the intersection or traffic lane, creating a safety risk to myself and other drivers, particularly at busy intersections. In some instances, the vehicle needed to be fully powered off and restarted before it would move again. This is a known and widely reported defect affecting Honda and Acura vehicles with the Auto Idle Stop system, currently under NHTSA Engineering Analysis EA25004. The problem has occurred repeatedly and unpredictably, with no consistent warning beforehand. The vehicle and its Auto Idle Stop system are available for inspection upon request. The problem has not yet been confirmed by a dealer, though I intend to bring it in for diagnosis. There were no warning lamps or messages before the failures occurred; the only symptom was the engine simply not restarting after an automatic idle stop.

After driving the vehicle and stoppping for gas or to run a quick errand the van sometimes will not start, or gives difficulty starting. Slow to crank or turn over, sometimes has to be started multiple times before it will restart. It happens after the motor has been running. It never has issues first thing or the first time turning the car on for the day. The issues come once the motor has been run. -took the vehicle in to Honda dealer on 6/8/26 they recharged the battery. -7/9/26 took van into Honda dealer they replaced the battery. 8/15/26 van still having issues starting once engine warm. Dealership said starter is failing and replaced the starter.

Sometimes the engine wouldn't start. Sometimes the engine would be slow to start. Checked battery and nothing wrong with it. Took it to Honda and asked to look into common starter problem. They did say the starter was faulty and replaced it.

Vehicle with 37k miles. When the idle stop feature is activated at a stop, it causes the vehicle to stall requiring a restart. The starter occasionally does not work as well. Starter and battery was replaced at 12k and the issue has resurfaced. This poses a significant safety risk.

Auto start stop feature caused car to shut off at lights- happened 4-5x. Very dangerous. Battery replaced but then still had issues. Starter replaced.

Starter is very weak when hot. 2 hour drive in summer heat and the van would not start after stopping at a gas station.

My van has an auto-stop feature that shuts the engine off at stop lights. This feature will now occasionally shut the car off, but then fail to restart it. We have stalled out at intersections with the van not restarting for up to a full minute. This is incredibly dangerous and needs to be addressed immediately

I was stopped at a stop sign and my 2025 Honda Odyssey shut off. I stopped the AIS engaged, then when I took my foot off the brake the engine didn't engage. The car wouldn't move. I took me about 30 seconds to get the mini van's engine to engage. This is the second time this type of incident has happened.
