With vehicle auto start/stop feature enabled, vehicle just shuts off when attempting to start back up after shutting off at a stop light. It has happened multiple times and recently it even happened with the auto start/stop feature turned off. Took it to the dealership and they tested everything to include the battery and they weren’t able to duplicate it. A review of forums showed other people with the same issue and it is pointing to a faulty starter, but no recall has been issued yet.
2025 Honda Odyssey complaints
Owner reports filed with NHTSA about this vehicle, newest first and reproduced as filed. They are unverified accounts: one proves nothing, and a pattern across many is the thing worth reading. Back to the full 2025 record →
When car is stopped it completely shuts off, goes into park and does not restart. This has happened 3 times, twice at an intersection and once as I slowed to a stop sign. The car didn’t restart and I had to push the engine start to restart the car. This was dangerously because it has happened while I stopped but also while I was slowing down at an intersection, the car would abruptly shut off. When this happens warning lights on the dash appear but go away once I restart the engine.
My 2025 Honda Odyssey has been completely shutting off after the stop-start shuts the engine off. When the car actually “stalls” is when I let off the brake and it’s time to start going. Then I hear a ding, the dash lights come on, and I have to frantically hit the ignition button to restart my car. This happens intermittently, without warning. I've been stuck at redlights afraid I will be rear ended because all of a sudden I can't move forward at a green light. My and others safety is at risk. Honda does not allow the start/stop to be disabled by default. It has to be disabled, manually, by the driver, every single time the car is restarted. So you can't just ignore this problem by shutting off the feature when the feature won't allow itself to be shut off by default.
The Idle Stop feature failed to restart the engine when I released the brake after having stopped at a traffic light. Eventually restarted after more than a minute of manually pressing the ignition button.
I came to a stop at a stop sign. Then "auto off" shut off the engine. Next, the vehicle went into park. A message came on screen telling me to press the brake and the start button. Doing so had no effect. Cars behind me started honking. After repeatedly stabbing the start button and opening and closing my driver's door, the vehicle eventually rebooted, and the engine started as normal. This caused a dangerous situation where other cars went into opposing traffic to get around me.
Auto start/stop functionality has resulted in vehicle stalling mid traffic as vehicle does not start and shutdowns. This has occurred in multiple occasions and most recently almost caused an accident with my family. We sent to dealer who checked battery and stated to issues. There were no warnings and dealer was unable to reproduce as they didn’t drive the vehicle. I have concerns with this new vehicle after finding other reports of this issue.
The car stalled then stopped when I was at a traffic light, I had to press the start engine button multiple times to restart the car. This issue has occurred 3 times within the last two months.
My car has been dying when I stop at stoplights. We took it into the dealership and they said the battery was sending error messages. So we replaced the battery. It is doing it again. Sometimes it starts but it is getting progressively harder to restart it. It is dangerous to be stalled at an intersection. The car is not even a year old.
I am having issues with my auto start/stop, also, occasionally has issues starting from a cold start! I was at a red traffic light, and once the light turned green I went to go and my car died. I had to put it in park and try and restart it and it took me three times for it to restart. Everybody was honking at me. This is a safety issue.
Hand control device for disabled drivers is correctly installed under the stearing wheel and works as intended. However, device has several very sharp right angle and corner points that, in the event of a collision, the sharp (not rounded) areas would severely damage driver's knees.
The idle stop system is malfunctioning. I had it inspected once previously and now trying to get it inspected again for the same occurring issue. The dealership continues to tell me to turn off the idle stop feature on the vehicle. My safety was put at risk because of the vehicle stalling and not kicking back on while being stopped at a redlight on a busy 4 lane highway multiple times now. The first time, I was by myself. The second time, my 8-month-old was in the vehicle with me. This causes a lot of panic as there are impatient drivers around me since I am unable to move my vehicle. I fear that this could happen on a freeway if there was construction, an accident or even while trying to turn in an intersection and getting hit because I can’t move my vehicle and often have my two small children with me. The first time the idle stop stalled, it occurred twice in a week. The first time was rather quick, and the engine kicked over quickly so I did not think anything more of it. The second time which happened a few days later (9/17/25), took about 5 minutes to get the engine going again and moving on the road (4 lane highway). I took it back to my local Honda dealership where they performed a diagnostic test and discovered the battery had dipped down to 7.22V when trying to restart, the battery failed the battery test and ended up being replaced with a new battery. The idle stop issue has now happened for a third time (10/21/25), with the same issues occurring and I am waiting t
Honda Odyssey EX-L sport 2025 has been facing the issue of idle stop not working causing engine to stall, engine failing to restart, shutting off completely during mid traffic especially during adaptive cruise control operation. This is causing an unsafe driving situation. While this issue was reported to Scott Clark Honda multiple times and they have claimed to fix this issue in Aug 2025, the issue continues to exist and root cause hasn't been fixed. This seems to be related towards the on-going investigation by NHTSA. Please help to resolve at the earliest since no further support is being received from Honda.
Since July 4, 2025, this can has intermittently shut off and stalled on me, my wife and my family and has refused to start. It has now been back to the service department of Trust Honda of Palmdale 4 different times for the same problem and the battery has been replaced on this van back in July. Most recently, it stalled just two days ago in rush hour morning traffic on the 405 Freeway going South in the San Fernando Valley. The display on the dash read “dead battery “. It took over 20 minutes for the van to start and my wife was able to move it off of the freeway to a safe location.
2025 Honda Odyssey EX-L My concern and issue is that the 2025 Honda. On 18 October 2025 the Honda Odyssey shuts down by its self after stopping at a red light. I believe it has something to do with the feature of auto start/stop system. This has happened multiple times. The vehicle sporadically fails to restart after coming to a complete stop. The engine shuts off as expected at a stoplight, but when I release the brake, the vehicle hesitates to crank over or start which has left me stalled in traffic numerous times. No warning lights or messages ever appear prior to the issue. This issued has left me in the middle of the road numerous time with traffic behind me. This takes a couple of minutes to restart the engine because the vehicle lights are turned on and it appears that the Odyssey doesn't have enough power to turn on the vehicle. But after multiple tries the Odyssey finally turns on. This is extremely dangerous because it can cause another car rear ending us and injuring my family.
Description of the Problem I am filing this complaint regarding a serious safety concern and poor quality repair on my 2025 Honda Odyssey, which I purchased new less than one year ago. 1. Engine Auto Idle Stop / Starter Failure Issue The vehicle suddenly shut down when the “Auto Idle Stop” feature was activated. This incident occurred multiple times, and I was unable to restart the engine until several attempts later. This creates a dangerous situation, especially in traffic or intersections. When I contacted the dealer, they confirmed that the issue is caused by a starter motor failure, and the replacement part will not be available until early November — meaning I must drive for over a month with this feature turned off. Many other owners have reported similar problems online, which strongly suggests a potential defect that should qualify for a safety recall. 2. Water Leak and Poor Quality Repair My vehicle also experienced a water leak from the roof area. The dealer attempted to fix it by simply applying sealing material on the roof molding (see attached photos). The repair looks extremely unprofessional, and I requested them to properly replace or reinstall the roof molding, but they refused. This type of repair is unacceptable for a new vehicle of this class and price. 3. Honda’s Unsatisfactory Response I contacted Honda Customer Service (1-800-999-1009) and spoke directly with a representative. However, I was told that: They cannot extend the warranty. They cannot offer
When I stop, they start stop, turns the engine off, but when I release the brake, the engine struggles to turn over and sometimes doesn’t and I have to put it in park to restart it. I have taken it to the dealership already once, but they said they weren’t able to reproduce it. I will be taking it back to the dealer to try again.
The issue involves the auto start/stop system on my 2025 Honda Odyssey Touring. When the feature is turned on, the vehicle intermittently fails to restart after coming to a complete stop. The problem does not occur when the start/stop system is disabled. During normal driving, the engine shuts off as expected at a stoplight, but when I release the brake, the vehicle hesitates or fails to crank, leaving it stalled in traffic. The Honda dealership confirmed the issue and stated that the starter motor needs to be replaced. The van has approximately 9,300 miles. No warning lights or messages appear before the failure. The problem occurs only when the start/stop system is active. This presents a safety concern, as the vehicle can lose power and fail to move when traffic lights change or when merging, increasing the risk of a rear-end collision or blocking intersections. The vehicle is currently being inspected and repaired by the Honda dealer and is available for inspection upon request.
Two concerning and dangerous malfunctions are occurring. 1.)When car is stopped at a light for more than 45 seconds the car engine shuts off, when I press on the gas the dashboard lights up and displays a battery light and advises me to restart the car. The car struggles to turn over. 2.) The car struggles to start on initial start as well. The dealership replaced the battery and it continues to happen, they advised me to disengage idol stop every time I start my vehicle to save the starter and prevent the car from stalling. This is obviously a problem with the Honda idol start that needs to be addressed. There are multiple threads in online forums about this issue with Honda.
If the car is standing in sun on a very hot day, upon starting the engine it will start beeping with all these errors blinking and disabling these controls. Once the engine runs for 15,20 minutes and the car cools down, the warnings disappear too.
Three times now since buying my van about 6 months ago brand new, I come to a stop light, the engine turns off, but then it won't come back on when the light turns green. I have had to put my hazards on while I frantically push the start button multiple times. Eventually it will start up but takes 1-2 minutes. I brought it into the dealer the first time and they blamed it on a weak battery. After it happened 2 more times, they are replacing the starter but I'm afraid that's not going to fix it. While I wait, i just have to turn off the idle start/stop button every time I start my van.
THE AUTO STOP/START OR AUTO IDLES FEATURE ON THE CAR keeps stalling after the car stops AT THE RED LIGHT. It can cause a rear collision.
Idlestop fail to restart engine multiple occasions at busy intersections.
The contact owns a 2025 Honda Odyssey. The contact stated that after opening the electronic passenger side sliding door, the door failed to electronically close while pressing the close button. The contact exited the vehicle and manually closed the door. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 3,000.
The contact owns a 2025 Honda Odyssey. The contact stated that the Engine Auto Start-Stop system failed to operate as needed. The contact stated upon coming to a stop, the engine shutoff; however, upon releasing the brake pedal, the contact became aware that the engine failed to restart as designed. A message of a systems failure was displayed, and an image of a pedal and the Push to Start button were displayed. The contact was able to manually restart the vehicle immediately. The contact stated that the failure had been recurring and had worsened. The contact stated that the vehicle could only be manually restarted after 10 minutes, nearly causing a crash. The dealer was contacted, and an appointment was scheduled for a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 16,000.
The idle engine feature is defective. Often, when stopped and the engine goes idle, it will not restart when the driver releases the brake. The van stalls, and the driver is forced to move the vehicle into park and start the engine again. This is dangerous and stressful because the driver behind you expects you to go, especially when the light turns green, but you are stalled, potentially leading to rear-end accidents.
Vehicle stalled on a highway after an idle stop event at a stop light. Vehicle went to PARK. Required a full restart by operator to go when light changed and traffic was flowing in other lanes. Dealership examined next day and indicated battery was good. Voltage dropping to 8V to 10V when starting. Recommended to disable idle stop each time vehicle is started. A new starter was authorized and placed on order.
Vehicle shut off and put itself in park leaving a stop light. Was hard to restart.
Brand new vehicle and system shuts down a few times when in idle mode..(stoplight, stop sign) then I need to restart the car again.
The moonroof on my 2025 Honda Odyssey spontaneously exploded while I was driving it on [XXX] between New Orleans and Slidell, LA. The date of the incident was [XXX]. I was traveling at about 65 mph, the outside temperature was 93 deg F and the sky was clear. The highway was smooth and there was no construction in the area which would have produced loose pebbles or rocks. The explosion was like an artillery piece had fired overhead. I was lucky to have maintained control of the vehicle and the moonroof sliding cover was closed preventing broken glass from showering down on my wife and me. The next day I brought the car to the dealership (Royal Honda, Metairie, LA)to report the defect and to have the car repaired. I was told by the dealer that the manufacturer does not inspect failures such as this one and that Honda declined to repair the damage under warranty even though the minivan had less that 4,000 miles on it and 3 months old.

My wife was driving our 2025 Honda Odyssey on [XXX] on a neighborhood road around [XXX]. She came to a stop sign and stopped to turn right. Upon accelerating to turn right, the emergency braking system activated slamming on the brakes and bringing the vehicle to an immediate stop. There were no other cars, pedestrians or other obstacles with any line of sight. The sudden stop caused her to whiplash hurting her shoulder. We brought the vehicle to Joyce Koons Honda of Manassas. They downloaded the data and confirmed that the emergency braking system had activated but there were no reason codes given. They couldn't find any other issue and test drove the vehicle for 10 miles with no incident. My wife was really shaken up by the incident and refuses to drive the car until an actual cause is found and fixed.

At a stop, the fuel save system shut the car off. When you take your foot off the brake the van fails to restart. If you try to restart using the push button the car will still not start because the transmission is still in drive. Then it takes awhile to get the transmission into park/neutral and then the van will start. The problem is intermittent 3 times in the last 2 months. No accidents just blocking traffic. My wife doesn't like that.
After going into Auto-idle at a traffic light. The engine did not turn back on when accelerator was pressed. Even after a restart. It took about 30 seconds.
I think there is a problem with the Auto Idle Stop system that has resulted in the starter needing to be replaced. But, the dealership says nothing is wrong. The Auto Idle Stop malfunction lights up when I let off the brake. I have gotten in the habit of turning off the AIS every time I started the car. However, it still is hesitating to start, which leads me to believe the AIS has killed the starter.
Van completely shut down while in an intersection and the battery light came on. It was hard to restart. Took it to the dealership and they cannot find the problem.
The contact owns a 2025 Honda Odyssey. The contact stated that the vehicle had a new feature that, when the vehicle was at an idle stop, the engine would shut off automatically, and while the vehicle was stopped for several seconds. The engine was supposed to restart automatically when the driver released the brake pedal. The contact stated that on two occasions, the engine shut off and failed to restart. The contact was able to restart the vehicle. The vehicle was taken to the dealer; however, no cause for the failure was found. The body control module was replaced; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 10,000.
Normal speed of 25mph on a clear warm day with no road obstructions when the BRAKE System Indicator (Red) illuminated. I pressed on the brake and had severe resistance and was barely able to stop the car. Two more indicators illuminated. One I believe was the Vehicle Stability Assist and the other I don't recall. The screen flashed "Call your Dealer". The Owners Manual states "Have your vehicle repaired immediately." The vehicle was hauled to Southeast Honda. Codes UO416-680416-F8, U0418-68, U3000-49I. The Brake Booster was replaced. I am concerned that an in-experienced driver traveling at interstate speeds might have a fatal issue.
I am reporting a recurring issue with my 2025 Honda Odyssey, which exhibits difficulty starting the engine. Approximately two months after purchasing the vehicle in Dec 2024, the original battery failed and was replaced under warranty. However, the vehicle continues to experience problems when attempting to start. When I press the start button, the engine hesitates, cranks slowly, or feels as though it nearly fails to start. This issue occurs intermittently, regardless of weather conditions or the duration the vehicle has been parked. No warning lights or error messages have appeared on the dashboard The problem has occurred multiple times, most recently on Friday August 15th 2025, and creates a safety concern, as the vehicle’s unreliable starting could leave me stranded in potentially hazardous situations, such as remote locations or adverse weather. I have not yet had the vehicle inspected by a dealer for this specific issue, but I plan to schedule a service appointment to diagnose the problem. The prior battery replacement suggests potential issues with the electrical system, starter, or related components, possibly linked to the auto start/stop system currently under NHTSA investigation for 2018–2025 Honda Odyssey models. Additionally when driving down the road especially at low speeds the engine hesitates as if it’s not getting enough gasoline. Lastly the AppleCarplay screen and all other associated screens randomly go out. I have been to the dealership 3 times for repai
On two separate occasions the vehicle’s engine has turned off when stopped as part of the Auto Idle Stop feature and then did not restart when I took my foot off the brake and pushed on the gas pedal. I was stuck in traffic frantically trying to get the van to restart and eventually was able to get it. This is a new van I’ve had less than a year. I took it to the dealer after the first incident and described the problem. They kept it for more than a day troubleshooting and didn’t find a solution. Verbally they recommended using the button that turns off the Auto Idle Stop feature that must be pressed each time the van is started to turn the off the feature. I’ve done that most of the time since, but I happened to forget this week and then it happened a second time where I was unexpectedly stuck in traffic with the engine not coming back on.
We get a warning light saying "Adaptive Cruise Control System Problem". Van has 4200 miles and it happens during hot days, usually at lunch time. I took it to dealer "Honda Cars of Rock Hill, SC" but they told me there is no code showing up in the Van. I emailed honda America with video but so far no response. The system just goes crazy, beeping and the cruise control is no responsive to cancel button or anything. We are not even using the adaptive cruise control when this happens. After you drive for a while, it goes away, like nothing happened. But when another hot summer day comes, around lunch time, it goes... it does it pretty much during high temps. never in the evening or night time. here is link to YouTube video I sent to Honda: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While driving approximately 40 mph, the vehicles emergency avoidance system activated and applied the brakes very heavily. We were nearly hit by a vehicle behind us, which nearly caused multiple accidents. There was nothing in front of us, and the road was co.pletely clear in front of us.
The auto on/off while idling will randomly fail. The car stalls, all emergency lights turn on and the car won’t start for a few minutes. This has occurred at stop lights and in traffic after coming to a complete stop and the car turns off when idling. The car is only 6 months old. The first occurrence happened at the 3 month mark and has become more persistent. I’ve had my battery checked and that was not an issue.
On two differed occasions the AIS system failed and left my car disabled at an intersection. I was sitting at a traffic light and the car died when I took my foot off the break and attempted to proceed through the intersection. Additionally, I have a faulty seat/seat belt. The seat does not register an occupant or indicates the occupant is not buckled in when they actually have fastened their seat belt.
On June 14th 2025, I reversed up my driveway, uphill, shifted to neutral to allow the vehicle to roll downhill a bit so I could straighten it out. While rolling forward, the transmission was jammed into park with no warning or interaction from me, causing my head to sling forwards in a whiplash fashion from the abrupt change in inertia. This was both harmful to me, to the transmission, and is a major defect. Engaging a transmission into park while moving is reckless, harmful and extremely dangerous. The failing component is most likely the transmission control unit and is available for inspection upon request, but has not been inspected by anyone other than myself. The problem is reproducible by me.
I am an engineer and my respect of the laws of probability makes me a cautious driver. I've had m+y 2025 Honda Odyssey for six months, but only driven it 500 miles since it cannot be trusted. I stopped at a light waiting to safely make a left hand turn. I began my turn with enough time for two vehicles to follow me. After pressing the accelerator the vehicle slowly responded. The stall left me in the intersection, so I accelerated hard to avoid being killed. The sudden acceleration was difficult to control and almost resulted in me going off the road. I've come to learn this resulted from a Honda design decision. They have a feature called "Auto Idle Stop" that is ON BY DEFAULT. I was never informed of this feature and believe this was a reckless, or should we say reckmore, decision. This was clearly a deadly design decision. The USG must fix this. In addition, the USG should charge the engineers, and their management, for reckless endangerment.
The contact owns a 2025 Honda Odyssey. The contact stated that upon opening the electronic tailgate, the contact noticed 2 inches of water at the bottom of the interior of the trunk. No warning lights were illuminated. The contact stated that a musty odor was emitting from the vehicle. No cause for the failure was found. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the carpet in the back interior has mold. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 2,500.
While driving in a construction zone, the vehicle's lane departure system jerked the wheel and almost made me leave the lane Very dangerous. Same vehicle, the A'C was found not operating and a dealer diagnosis found that the system was overfilled and that an electrical connection was not hooked up from the factory. Same vehicle, body panels are not properly aligned from the sliding door to the passenger side door, gap is almost 1/2 inch.
While driving vehicle, the sunroof exploded. I had to fabric inner aspect closed so glass did not enter the vehicle. My [XXX] was in the 2nd row and would have had glass in her face if I had been driving with the fabric part open. Honda is fixing the sunroof currently but I feel unsafe driving with it now. I was on a side street with no overpass near, no cars around and no other vehicle to throw rocks. It simply exploded.
