2025 Honda Odyssey complaints

When the engine shuts off while braking at a light/stop sign etc occasionally the car will fail to turn the engine back on and the car will go in to park and the only way to get in to drive is to restart the car. This happens once or twice a month.

My 2025 Honda Odyssey Elite repeatedly shuts off completely while stopped, with the Auto Idle Stop feature engaged, and fails to restart on its own. The engine dies at a complete stop and will not restart until I shift the vehicle into Park and manually restart it. This has happened more than six times. It occurs only at complete stops such as traffic lights and stop signs. No warning light illuminates. This creates a safety hazard because the vehicle is dead and immovable in active traffic until I can restart it, exposing me and my passengers to rear-end collision risk. This matches the known Auto Idle Stop defect already under federal investigation for this vehicle.

Auto Idle Stop feature has caused the vehicle to stall / shut down at a stop light on several occasions causing hazard when we can't drive. Entire engine has to be stopped and restarted which is scary in heavy traffic.

-Defective Starter. -Starter randomly fails to restart vehicle after being warmed up. -When the DC motor internal copper windings get heat soaked after being driven and warmed up, the motor's internal resistance gets too high to draw sufficient current to turn over engine properly. This happens when intentionally shutting off motor (ie. getting gas, going into a store then coming out in a few minutes), the engine either will not crank at all, or cranks about two engine revolutions, will not start and then stops trying and remains in full accessory mode. It will not attempt a restart either. The only remedy is to fully shut down the vehicle, then try a fresh start after a few seconds. Sometimes it will start the engine, sometimes it will repeat the issue and you have to try again. This is EXTREMELY DANGEROUS when this problem occurs when the vehicle is at an intersection or traffic light, shuts itself off due to the auto-start/stop, then fails to restart the engine when expected when the light turns green. Especially at traffic lights if you're the first car in line., and especially if you're the first car to go with traffic behind and in a single lane of traffic. Having to totally shut the car down, then do a fresh restart while blocking an intersection with tons of cars behind and all waiting on your car to decide if it wants to re-start with cars flying around you into the shoulder or ditch to get around is an extremely dangerous position to be in, forcing other drivers int

When at a stop, the van is supposed to start again. There have been at least 4 times now that it did not automatically restart. After the 3rd time, I was at the dealer for routine maintenance and mentioned it. He said if it does it again to let them know and they will need a full day to look at it. The most recent time I was at a major intersection in town at a red light. Light turned green and the van would not go. My adult son was with me and said it took about 30 seconds for me to get the van going again. It is scary because I live in a busy town. The service advisor said he has the same van and ALWAYS turns the idle stop to off when he drives. I try to remember to do it, but sometimes I forget. I am calling the dealer now but really don't want time without a vehicle.

After approximately 60 miles of highway driving, I was stopped at a stop light and the auto engine off feature automatically shut the engine off. When I lifted my foot from the brake pedal in attempt to accelerate forward, the van did not turn back on and a battery warning light showed on the dash. I attempted to restart the van without success x 2, it was not turning over. My van was stalled in the middle of the road, cars passed around on both sides. Upon my third attempt to restart the van, it did restart and I have had no further issues since. Though, I have been shutting off the auto engine off feature since that time. I understand there is a well known issue with the auto engine off feature of Honda Odysseys in this generation. I am respectfully advocating for a formal recall as a stalled van in the middle of traffic poses significant risk to the public.

This was an auto stop-start system failure. The Honda dealership in Frisco inspected and attributed this to battery life but did not guarantee this was the cause of the issue. There were no other signs of failure prior to the incident. A description of the incident is below. While turning right departing a parking lot, the vehicle auto stop-start enabled during the brief stop and the feature turned off the vehicle. When accelerator was pushed to proceed, the car started flashing lights with a warning message on the dashboard, the car was then automatically put into park by the system, and would not proceed to move without turning the vehicle off and back on. If this had occurred in another location, it would have been extremely dangerous as it took some time to turn the vehicle back on.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving off the expressway and stopping at a red light, the contact pressed the ECON button, and the vehicle failed to start. The contact opened the driver’s side door and press the start button to restart the vehicle. The vehicle was restarted and operated normally. The contact stated that the failure had occurred on two separate occasions. The cause of the failures were not yet determined. The local dealer was notified of the failure, and a service appointment was scheduled. The manufacturer was not yet notified of the failures. The failure mileage was 8,000.

While driving straight on the highway on a sunny day the car left the lane on it's own, resisted attempts to get it back into the lane, and crashed into the concrete barrier after we swerved around and the car bounced around. Lane keeping assistance and automatic cruise control were active. The lane lines looked perfectly fine. A couple minutes before the accident the car left the lane unexpectedly but we were able to get back into it. Before going on the trip we took the car to the dealer and complained about issues with the car not starting after it shut off while idle at stop lights, or not starting properly, like engaging the parking brake and getting stuck, or starting and rocketing forward even when I only pressed lightly on the gas, leading to loss of traction. They checked the car and said everything looks fine and the tires have 5mm of tread and don't need to be replaced, and they rotated the tires and changed the engine oil. I'm not sure if the issue was with the power steering failing, or traction being lost, or the sensors having an issue causing the car to think the lane was somewhere else and not letting us leave where it thought the lane was. Driver has tons of bruises still and it's been over a week. The other 4 passengers seem ok. The insurance company said the car is totaled and is taking possession of the car. The only warnings lights or messages the car gave us before the accident were about the car having an issue starting back up when all the cars were b

Engine fails to restart after the Auto Idle System shuts it down, leaving vehicle stranded in traffic. The issue is sudden and unpredictable, and may not appear in inspection. A stalled car in live traffic is a safety concern. The vehicle is at a dealer for diagnosis and repair. No warning appeared before the problem began happening. (About 5 times in 2.5 months.) Sometimes when it occurs, a brief error message seems to appear on the dash, but quickly disappears. It usually takes cycling through restarting the car to get going again. Not a good environment to stop and take video, although it's almost impossible to record.

Engine will fail to start when shut off to stop light or when shut off at anytime when engine is hot. Very dangerous situation. Acts like starter is dragging. There is a clunking in the steering column when making a turn mainly to the left that can be felt in the steering wheel. Driver seat is splitting open on the side. Keeps setting code p0441 for evap system..

I am reporting a critical safety issue regarding the auto-start-stop system on my 2025 Honda Odyssey. On June 15, 2026, the vehicle's engine shut off at an intersection as designed but failed to restart, stranding the driver in active traffic and presenting a severe safety hazard. I previously brought the vehicle to an authorized Honda dealership approximately two weeks prior to this incident after noticing early symptoms of this failure. At that time, the dealership diagnosed the issue as low battery voltage and replaced the battery; however, this repair did not resolve the underlying fault. The vehicle continues to unexpectedly stall during traffic stops due to the auto-start-stop failure, representing an ongoing and significant danger to the vehicle occupants and other motorists.

While running in expressway, van lost it's power and went to parking mode while driving x 3, have to turn on and off the engine in order to restart in the middle of expressway. this put myself, 2 toddlers, and other family member in the car to get hit by the vehicle that is with us especially in the express way, and could have resulted to death at worst. Luckily able to take to the dealer and they said that the battery was dead and not holding any charge at all, this happened 6/10/26, we bought the car 4/2025 brand new, and currently have 8500miles on it. Dealer replaced the battery the same day. there was no warnings on the dashboard that was telling us that the battery was getting low or having any issue. this incident could have killed us in an instant with no warning at all. this is very dangerous.

2025 Honda Odyssey has completely shut down at a traffic light and stop signs. This has now happened multiple times. When waiting at a red light the car fails to restart the car when I take my foot off the brake and I get a message “to continue to drive depress brake pedal and push switch” . The red battery light comes on and the car puts it self in park. The car fails to turn on or turn all the way off. The car is stuck in park in the middle of traffic.

Vehicle shuts off with with the start/stop feature. then will not restart the motor after taking foot off the brake causing a dead vehicle in the road with no warning. Then its a scramble to get it to restart and its difficult to start. this happens at random and seems like honda refuses to fix.

This event has happened multiple times in various situations. While sitting at a red light the auto idle stop feature was engaged and the engine turned off as normal. Upon lifting my foot off the brake, the car fails to restart leaving me stranded in the middle of the intersection. This caused an unsafe situation as I was unable to restart the vehicle until after a few tries, leaving cars having to navigate around me in busy intersections. I have also had situations where I was unable to start the car while in park. It would start after the second try. This car was purchased in Fall 2024 and started showing this issue less than 1 year after purchase. Given the age of the vehicle, it should not have battery or starter issues this early on in the lifecycle of the vehicle. Looking online, other 2025 Honda odyssey drivers have posted similar issues. At first I thought it was just a fluke, but lately I have been having more frequent occurrences. A recall must be issued on the battery/starter to prevent future accident that is just waiting to happen. Being stranded in an intersection is incredibly unsafe.

Electrical restart feature failures, battery dash indicator comes on and the restart feature won’t engage. This has happened on several occasions on busy roads with lights vehicle won’t move without manually turning off vehicle and putting into park to restart. Was almost rear ended by large truck after being unable to restart vehicle after being stopped at a red light.

While having the idle-stop system in use our van had shut off three times at a red light when we took our foot off the brake to press the accelerator. This left us at an intersection with a dead engine. Not knowing what was going on it took us a few moments to get the van turned back on and into drive. I had the van in for routine service and asked them to look at it with no issued found. It will go in again next week for additional checks. The only warning light is the battery icon comes on. Battery was checked at the dealer with no issues found.

2025 Honda Odyssey Auto Idle Stop fails to restart engine after automatic shutdown at intersections; vehicle must be restarted manually; safety hazard; repeated occurances; video documentation made. Reference: NHTSA EA25004

Bad starter. When utilizing auto start/stop, the engine would fail to restart at stop. The car would need to be shifted back to park, turned all the way off, and then back on to restart, resulting in a delay - an unsafe practice at an intersection.

Sitting at a stop light. The car stopped the engine with the auto start stop system. When I released my foot off the brake. The engine didn’t start back up. I had to put it in park. Press the start button multiple times and it finally barely started. This was in traffic right while the light turned green.

Had the starter & battery replaced November 2025. It’s now June 2026 and it still is having trouble starting. It will sometimes not start and then just make a clicking noise and all the lights in the dash come on and air, but engine won’t well start. Then you take foot off break, then turn it off and try again it will start. The dealership ran tests and said everything was fine. When we first had this problem the car would stall out and shut off in traffic.

Vehicle has auto start/stop and when shutting down at a stop will fail to start back up. Have to shut vehicle down completely and then try to start back up.

-Engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. -This issue presents a significant safety hazard for my two small children and me. On multiple occasions, we have been unable to move due to severe traffic congestion, leaving us vulnerable to aggressive and hostile behavior from other drivers. The resulting situation is both stressful and unsafe, particularly when traveling with young children. -Issue has happened several times -No warning lamps, messages or other symptoms of the problem prior to the failure -Reported the issue to the dealership as the vehicle is still under warranty. Per service technician, there is not alarms or issues with the vehicle. Nothing is being done by Honda to address this issue. Please help

Auto Idle Stop system engages (turning the engine off in highway traffic and at a red light or stop sign), the engine occasionally fails to restart on its own. I have to put in park and restart. Almost causing accident started when van had 25k now I have 46k on the odometer and Honda said no longer covered.

Engine start/stop feature is not working properly and it nearly caused a few accidents. I am getting rid of this car and going to purchase a Toyota Sienna. Android Auto doesn't work either which is a known issue as well and it is a basic safety feature to keep driver's attention on the road and not on their phones.

The vehicle’s auto stop-start randomly does not start the engine when releasing the brake. The vehicle is temporarily disabled on the roadway and it puts itself into Park. The vehicle requires intervention to restart the engine and the delay takes several seconds and poses a safety risk by blocking the roadway.

While the van is at a complete stop at the intersection it shuts off and behaves as if it needs to be restarted. A message appears instructing me to press the brake and push the start button to start the van. I took it to Honda, but they were unable to find the issue. They replaced the battery to see if that would fix the problem, but about a month later, it happened again.

Idle Stop issue- We were at a stop light and the engine idle stopped. When the light turned green and the foot was taken off the brake, the engine did not turn back on. We had to turn hazards on and turn van completely off. We tried several times to restart the vehicle and the engine did not respond. We finally got it to turn on a couple minutes later but the engine sounded as if it was struggling to turn on.

On three separate occasions — May 17, May 20, and May 29, 2026 — the vehicle's Automatic Emergency Braking (AEB) / Collision Mitigation Braking System activated without cause while traveling at highway speed (one of these occasions was on an interstate). On each occasion, no vehicles, pedestrians, or obstructions were present ahead of or around the vehicle. The road was clear. The activation produced a large bright yellow dash notification and the vehicle's brakes activated. Minor children were passengers in the vehicle during these events. The vehicle has an active Florida Lemon Law case with multiple prior documented electrical nonconformities. When I attempted to schedule yet another service appointment to have THIS defect diagnosed, the dealer, who sold me the vehicle, refused to service the vehicle due to the pending lemon law status and directed me to contact Honda Corporate. When I asked the dealer to provide their refusal and the requirement for Corporate authorization in writing, they declined to do so. Honda Corporate has not responded in over 72 hours. Photo and video evidence of other nonconformities is available.

Auto Idle Stop (AIS) system fail to restart: The engine fails to restart on its own after a complete stop at a traffic light or intersection with the Auto Start/Stop function engaged, putting the driver in dangerous and panic situation.

Noise coming from front driver side suspension or steering column/components. The noise is very light, but sounds like a clunking/rattle and can be felt through the steering wheel. It is intermittent. Because I am unsure what is actually causing the noise, I cannot state whether it is actually part of the suspension system or steering column area. The dealership cannot replicate the noise, so it has been turned away twice now. Does not feel safe. Searching other odyssey forums, it is something that is reproduced by others who have bought a 2025-2026 Honda odyssey.

The Auto Idle Stop has failed to restart the car when stopped at a traffic light. This has happened twice now, and has caused me to become a road hazard as I am not able to get the car turned back on before the light turns green. This has happened twice in the past month (May 7 2026 and June 1 2026). Have not yet taken the car back to the dealer. No warning lights or anything came on prior to the incident. Just stopped at a light and the engine stopped, then did not turn back on when the brake pedal was lifted.

Car completely turns off when I’m stopped and idle stop has engaged. Seems to happen when the AC is running hard. Sometimes, the car turns back on by itself in seconds. Other times, I have to turn the car back on myself by pressing the “engine on” button, and I struggle to get the car to turn back on. Very dangerous to be obstructing traffic at busy intersections or on a busy highway when stopped while another car ahead is making a turn. I’m scared to drive this car with my children in it. It is a minivan! I understand this is a known issue under investigation by NHTSA, but I’m struggling to get my local Honda dealer to acknowledge and address it. This issue happens at least 1x a day when I’m running the AC.

While stopped at a red light the engine turned off with the engine restart function. When I released the brake the engine attempted to start and then completely stalled. I had to get the vehicle in park and restart the engine with took it a few attempts of pressing the start button. The has happened a few times with this vehicle. Dealers have been unable to replicate the issue to try to solve the problem.

The Honda Auto Idle Stop Start isn't working properly. I applied brake and car turned off, when I released the brake the vehicle did not start. Also vehicle seems hesitant to start at times.

Engine fails to restart on its own from a complete stop at a traffic light or road intersection when the Auto Idle Stop function is engaged

The starter is failing and with automatic dial shut off it caused an issue while in middle of intersection waiting to turn. The car would not start and had issues.

The Auto Idle Stop (AIS) system malfunctions during normal driving. When coming to a stop, the AIS shuts off the engine as designed, but the vehicle then fails to restart when the brake is released. The vehicle shifts itself into Park automatically without driver input, either before or at the same time as a dashboard message appears instructing the driver to depress the brake pedal and press the start button. When the start button is pressed, the dash resets but the engine does not start. The only way to recover is to fully power the vehicle off and restart it, which is difficult and unsafe at a busy intersection or red light. This puts the driver and others at serious risk. The vehicle becomes immobilized in traffic with no ability to move it out of the path of oncoming or following vehicles, creating a risk of being rear-ended. The unexpected automatic shift into Park is also a vehicle control concern, as the driver does not initiate it. The problem is intermittent. The vehicle has been taken to an authorized dealer twice. On the first visit the dealer kept the vehicle several days with a loaner and attempted to replicate the issue but could not. On the second visit the dealer kept the vehicle one day and again could not reproduce it. A third diagnostic visit is scheduled, during which the service manager intends to drive the vehicle to attempt replication. As of now the failure has not been confirmed or reproduced by the dealer. The vehicle is available for inspection upo

The vehicle turned off at a red light and would not start up again.

The idle stop on my 2025 Odyssey sometimes does not turn back on when it turns off at a red light. I have to then completely turn off my vehicle and turn it back on in order for the vehicle to work again. Also, when first turning on my car sometimes It’s very laggy in fully starting. This is a great safety concern, especially when at a red light or at a stop sign when trying to apply gas and it doesn’t turn back on. This is a problem we’ve heard is being experienced by 2025 Odysseys. The dealership we took it to could not replicate the problem they said the battery was totally fine.

AIS system causes the 2025 Honda Odyssey Elite to stop and fail to restart when stopped at traffic light intersections—the car will not restart which is very scary in traffic with kids in the car. I had starter replaced at a Honda dealership, but the dealer could not say whether it was same part or upgraded part, which means the starter may overheat and shut down again because Auto Idle Stop. This began happening when car was less than one year old.

Stopped at light. Car turned off per the start/ stop feature. Removed foot from brake and pressed gas pedal, car started but brake light came on and continued to flash. Had to pull over and stop before light would stop flashing and go away.

The contact owns a 2025 Honda Odyssey. The contact stated while driving at an undisclosed speed, the brake pedal was depressed, however the auto idle did not function as intended. The contact stated that the vehicle stalled. The vehicle was taken to the dealer where it was diagnosed with a failed battery. The contact was informed that the battery needed to be replaced. The failure reoccurred. In addition, the contact stated that the vehicle stalled, and the engine shut off. The contact stated while attempting to start the vehicle, the vehicle failed to start. The contact stated that after several attempts, the vehicle started. In addition, the contact stated that when the auto idle feature was disabled, the failure did not occur. The vehicle was scheduled for diagnostic testing within the next few days. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was 100.

Vehicle has stopped running multiple times while at stop signs or traffic lights when engine is at idle and not running. The vehicle has to be restarted to go after shutting off while in traffic. It is very concerning when this happens in live traffic. The dealer has had the vehicle for days and were not able to replicate what happened. Asked me for more information on what was being used when it happened. They say they ran tests and were unable to get any codes to show what might have happened. The only thing I have seen was reports that the idle stop feature was unavailable previously. Not sure when that happened? This has happened at least 6 different times, last time being May 8th 2026.

CMBS error again now having lane assist error

I have encountered several instances where the vehicle goes idle at a spot light as expected. However the vehicle fails to restart when letting off the brake. Instead, the vehicle shifts into park. Once the vehicle shifts into park, I am unable to shift into drive. I must restart the vehicle and try en shift into drive. This is extremely dangerous and has happened multiple times. This vehicle is one year old and has 9k miles.
