2025 Honda Odyssey: Recalls, Complaints & California Lemon Law

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.

NHTSA #11742629

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.

NHTSA #11741667

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.

NHTSA #11740954

We've been experiencing issues with the Auto Idle Stop feature (the auto restart in particular). On multiple occasions, the vehicle will automatically turn off the engine while stopped in traffic, but will fail to start back up, requiring the driverto manually turn the vehicle off and back on via push button starter (sometimes multiple restarts is necessary to get it moving again). This seems VERY similar to the investigation referenced under - EA25004.

NHTSA #11736564

Auto start stop not working. This is happening quite a lot where there auto stop in activated and then the car wont start back. Resulting in the car having to be completely restarted.

NHTSA #11736569

Engine would not restart after the idle stop at a traffic light. I needed to put the car in park and turn the engine off and restart it. Shortly after this, at another traffic light, the idle stop caused a delayed restart of the engine and caused the vehicle to lurch forward suddenly. This has happened once before as well.

NHTSA #11736687

Many, many times vehicle stop/start feature has failed to start car. Have been stranded at busy intersection having to put car in park and restart car. Extremely dangerous. Took car to dealer and they deny there are any problems.

NHTSA #11733487

This is the second time I have taken it to the dealership. When sitting at a stop and the automatic stop and start happens, it acts like it does not want to crank back up. Last time the dealership said it was the battery; they replaced the battery, but that has not fixed the issue. if I am at a stoplight and it does not start back, that is not a good feeling my wife now does not want to drive the van anymore because of the seriousness of this issue as well has having young children in the car. This is a van that was bought brand new and has been in the shop more than it has been driven.

NHTSA #11732574

This vehicle comes with idle stop. Many times especially at red light, the idle stop switches off the engine but then it does not restart automatically. We have to switch off the car and then restart it again. This takes some time. In the meantime, it is the panic with cars honking behind us.

NHTSA #11727396

Vehicle failed to restart after Auto Idle Stop engaged while stopped in traffic. The engine shut off as expected but did not restart when releasing the brake pedal. A warning message appeared briefly on the dashboard but could not be fully read due to traffic conditions. The vehicle remained unresponsive until I shifted into Park and manually restarted the engine. This has occurred intermittently. The vehicle was previously evaluated by a dealer for the same issue, and the battery was replaced at approximately 15,000 miles. The problem has continued to occur after battery replacement. This creates a safety concern due to inability to move the vehicle in active traffic.

NHTSA #11726604

At a stoplight vehicle turned off and gave a battery light and vehicle lost all power and placed vehicle in park. A warning message came up very quickly about something wrong with the auto start/stop system on display. Vehicle remained off until after opening door and pressing engine start stop button multiple times along with depressing and releasing brake pedal multiple times. This occurred the first time in late February 2026 then again on 3/21/26. Vehicle has 46,880 miles currently.

NHTSA #11726062

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.

NHTSA #11741003

Engine Shutoff/Idle Stop Failure: The vehicle fails to restart after the automatic idle stop engages in traffic, requiring a manual restart. Electrical System Malfunctions: car dying at stoplights, loss of power, and, in some cases had to restart in "limp mode" where the vehicle is restricted to 1st gear,not very safe on major highways. Reported this to Honda during service on 3-16-26, they didn’t find anything? Has happened 7 times since it was serviced.

NHTSA #11731160

the car will shut off at stop lights and randomly not start back up when the light turns green, then it will take a few minutes to start back up using the push button, this ONLY occurs with the automatic start stop feature of the car my wife drives the car with our two young children and being stuck in intersections randomly is not safe for anyone ,. we have told the dealer about the issue and they have failed to duplicate the issue and said nothing is wrong,

NHTSA #11723022

This vehicle is a 1 year old (2025) Honda Odyssey with roughly 11,000 miles. On two separate occasions now, the auto start-stop feature has caused the engine to die altogether. On both occasions, the vehicle stopped at a red light in a busy intersection, the auto start-stop feature turned off the engine (intentionally), but when the light turned green and my foot came off the brake and onto the gas pedal, the vehicle died entirely. A number of lights and an error message illuminated on the dash board. From my online searches, it seems as though this is a very common issue. 1. What component or system failed or malfunctioned, and is it available for inspection upon request? Auto start-stop / engine. No not available. 2. How was your safety or the safety of others put at risk? Having your vehicle die at a busy intersection or stop sign is a huge risk. It can cause others to try and swerve around you, or it can cause someone not paying attention to rear end you. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle will be brought to the dealer in the coming days. Unfortunately this is my only vehicle and I cannot afford to lose it for an extended amount of time, therefore I have to prolong inspection and servicing. The issue has happened to me twice, and has happened to countless others online. According to others on the internet, the dealers are typically slow to address this issue, and even when "addressed" the issues seem to continue. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, see #3. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings prior to the engine cutting out altogether. Only a message after the failures. In both cases I do not remember what the messages said because I was scrambling to restart my car in a busy intersection.

NHTSA #11722359

I’m experiencing issues with the Auto Idle Stop system. The engine fails to restart on its own after a complete stop. I get an error message and I have to manually restart. This has happed at stoplights and in the middle of an intersection during heavy traffic which is a big safety issue.

NHTSA #11723992

i bought this van brand new for over $53000 and it has been hesitating to start for months. i had the battery tested and came back good. The van hesitates to start and sometimes i have to redo the push button because it fails to start the first time. Yesterday, 02/23/2026 the van left myself and the kids stranded at walmart. it would not start for anything yet the lights and radio work and acted like it was not the battery. i had to call my husband to come get us. we went back hours later to jump it and it started. something is faulty with the started or electrical system to start it. i have another appointment to test the battery and i know its going to test good because i just had this done a month ago and it still hesitates to start. i am not impressed at all and readying online that i am not the only one having this problem. it needs looked into.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving approximately 20 MPH, the vehicle inadvertently shut off in the middle of the road. There was no warning light illuminated. The vehicle was immediately restarted and driven to the residence. Additionally, while at a complete stop at a red traffic light, the engine Auto START/STOP system failed to restart the vehicle after releasing the brake pedal. The contact pressed the Push to Start button to manually restart the vehicle. The contact stated that the failure had occurred on several occasions. The manufacturer and the local dealer were notified of the failure. The cause of the failure was not yet determined. The failure mileage was 18,266.

NHTSA #11735073

Complaint Description: While driving my 2025 Honda Odyssey, the Auto Idle‑Stop system engaged in the middle of an intersection at a traffic light, shutting the engine off as designed. When I released the brake pedal, the engine failed to restart, leaving the vehicle stalled in traffic. The dashboard displayed warning indicators including the battery light, and the only way to move the vehicle was to turn off the car completely several time and try to manually restart the engine. This issue has occurred multiple times and poses a serious safety risk, especially when it happens in intersections or heavy traffic. I almost got hit by an oncoming car! On each occasion, surrounding traffic was forced to maneuver around my vehicle, creating the potential for a rear‑end or a side collision. this has been happening for a long time now and these instances are occurring almost weekly at this point. They are increasing. I have seen that other 2025 Odyssey owners are reporting the same issue — engine shuts off after Auto Idle‑Stop activates and will not restart — sometimes requiring a full restart and causing dangerous traffic situations on carfax.com. Based on similar NHTSA‑documented complaints and investigations into Honda Auto Idle‑Stop restart failures, this appears consistent with a known defect pattern involving stalled engines and failure to restart after idle‑stop engagement. (lawinfo.com and edmunds.com) The dealership has already replaced my low pressure fuel pump and state that they are fulkly aware of the issue and have not provided a permanent fix, and the problem continues to occur unpredictably. My wife and 4 children are in this car all the time. This defect could easily lead to an accident if the vehicle becomes immobilized in moving traffic. I am reporting this to ensure it is documented as a potential safety defect requiring investigation and mitigation.

On multiple occasions our vehicle has turned off at a stop (auto start/stop) and failed to restart upon pressing the accelerator. It then takes several seconds to be able to restart and get moving.

NHTSA #11733244

Over the past month, I have experienced several incidents where my 2025 Honda Odyssey’s Auto Idle Stop (AIS) system failed to restart the engine after stopping at traffic lights. Each time, the engine did not turn back on when I released the brake, leaving me stalled in traffic and prompting error messages on the dashboard. There is currently no way for owners to permanently turn off this feature. When I took my vehicle to the dealership, I was told my starter was already having issues despite the car having less than 10,000 miles on it. This ongoing problem has made me concerned for my safety and the reliability of my vehicle.

NHTSA #11707794

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. This is happening at stop lights where there is the risk for other cars to safely go when the light turns green. I have to completely shut off the car and restart the engine while traffic is going on green.

NHTSA #11706780

Idle stop engine turned engine off at a stop light. When the foot was removed from the brake pedal the engine struggled to start up. It took several attempts to get the engine to start up. This has occurred before and the dealer replaced the battery. However, it is now happening again. There were no warnings .

NHTSA #11705729

Stopped at red light. Auto start/stop engaged. Light turned green let off of brake and pressed gas. Engine did not start. Couple seconds later engine started.

NHTSA #11701805

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.

NHTSA #11698810

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.

NHTSA #11697656

The vehicle intermittently fails to restart after the auto start/stop stopped the engine. This happened several times when stopped at a traffic signal, nearly causing an accident when cars behind expected to move after the traffic signal turned green. There were no warnings or indications prior to the failure to start. Multiple attempts to restart the vehicle failed until at least a minute or so had elapsed. The vehicle has also intermittently failed to start after being parked for a few minutes after being driven for 20 minutes or so. The starter has generally sounded weak when starting, and when it fails to start it sounds like the engine tries to start turning for a fraction of a second before it stops trying to crank the engine. It almost seems like the start duration is too short or the ECU thinks the engine has successfully started when it hasn't. I brought the vehicle into the dealership to have this checked, and they replaced the battery saying it was bad. However, the failures to start continued to happen shortly after. I returned the vehicle to the dealership to be checked again. They have not yet identified anything that could be causing the issue. They claim the battery and starter test good. Based on similar complaints, it seems that this is an issue with many of these vehicles. Honda needs to identify the root cause of this failure to start issue.

NHTSA #11700984

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.

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.

NHTSA #11740574

The vehicle's Auto Idle Stop system shuts off the engine at stop lights and other low-speed stops and, on multiple occasions, fails to restart, and the AIS disable button is sticking. We disable AIS every single time we drive the vehicle, and on multiple occasions the button has re-engaged itself mid-drive, meaning the safety hazard cannot reliably be avoided even with the workaround Honda recommends.

NHTSA #11736023

The car intermittently struggles to restart or dies and will not restart after stopping at a stoplight or stop sign due to the auto stop start. Even when the engine restarts after a stop, of often sounds like it’s struggling. The car has been taken into the dealership multiple times and the battery has been replaced twice. Honda dealer claims there’s no known issue despite numerous complaints online and report of a federal investigation into this issue with many Honda Odysseys and specifically the 2025 model year.

NHTSA #11736211

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.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the idle stop feature turned off. The contact stated that the parking brake unexpectedly engaged, and the vehicle shut off with the message “Idle Stop Not Available” displayed. The contact was able to restart the vehicle. Additionally, shifting the vehicle out of park became difficult, and the contact had to wait an extended period before the vehicle could be restarted. The contact stated the failure would not occur while the idle stop feature was engaged. The vehicle was taken to the dealer, but was not diagnosed or repaired. The dealer informed the contact that the failure could not be duplicated. The contact was advised to return the vehicle if the failure persisted. The vehicle was taken back to the dealer; however, the vehicle was not diagnosed or repaired, and the dealer refused to disengage the idle stop feature. The manufacturer was made aware of the failure. The failure mileage was approximately 23,000.

NHTSA #11731689

Multiple times since purchasing the vehicle, the engine fails to restart after the automatic idle stop feature engages at red lights or stop signs. When I release the brake to resume driving, the vehicle attempts to restart but makes a struggling or grinding noise and then stalls completely, similar to a dead battery. The vehicle becomes unresponsive and does not restart immediately. I am forced to turn the car off and attempt to restart it multiple times, often waiting several minutes before the engine turns back on. This has occurred in traffic, creating a safety hazard due to vehicles behind me and my inability to move the car. The issue appears to be related to the automatic idle stop/start system and may involve the starter or battery failing to properly restart the engine.

NHTSA #11731298

When I am stopped at a stop light or in traffic my auto start fails and kills the electric in my vehicle when I push the pedal to go. This has happened several times and in one instance, almost caused me to be rear ended. It took several attempts to restart the car all while other cars are buzzing past me. It is currently at the Honda dealership for the 4th or 5th time for this same issue. My battery was replaced all ready thinking that was the solution, but it was not. I personally know of two other people having this exact issue with their vans.

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.

My van seems to struggle when traveling longer than 80 miles. I stopped on a trip at a rest stop and it would not restart. I had to get jumped and I purchased a new battery. I took my van into Honda and both batteries tested fine. No code is being produced though the dealership was able to replicate the issue once. After longer trips while using the air conditioner also have an issue with the auto/stop start not reengaging after being at a stop light. The dealership told me nothing is wrong a battery terminal was loose after they kept it for a week which I do not believe.

COMPLAINT: 2025 HONDA ODYSSEY AUTO START/STOP SYSTEM FAILURE Component Failed: Auto start/stop system fails to restart engine after automatic shutdown. Vehicle available for inspection. Appears related to investigation INOA-EA25004-10033. Safety Risk: Vehicle has failed to restart approximately 12 times since May 2025, all at intersections with active traffic. When auto start/stop engages at stoplights and fails to restart, the vehicle remains stationary and blocks traffic lanes when lights turn green. This creates hazardous conditions where other vehicles must maneuver around a stalled vehicle in intersections, risking rear-end collisions and traffic disruptions. Dealer Confirmation: Yes. Authorized Honda dealership tested battery (good), contacted Honda customer support directly. Honda acknowledged the issue but provided no diagnostic solution or repair procedure. Dealership's only recommendation was to manually disable auto start/stop every time the vehicle is operated. This is unacceptable for a new vehicle and defeats the purpose of this factory system. Manufacturer Inspection: Authorized Honda dealership consulted with Honda customer support. No fix or remedy provided. Warning Symptoms: None. No warning lamps or dashboard messages appear before or during failure. Auto start/stop system operates normally until restart phase, then engine fails to restart. First occurrence May 2025. Problem occurs intermittently.

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.

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.

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

NHTSA #11740363

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.

Description: Subject: Formal Warranty Claim – Spontaneous Glass Breakage and Request for Immediate Assistance Serious and unexpected failure involving my vehicle, a 2025 Honda Odyssey Elite (VIN: [XXX] ), currently with approximately 26,000 miles. On April 19, 2026, I submitted an initial complaint to Honda concerning what appears to be a spontaneous breakage of the rear side (fixed quarter) glass. The vehicle was parked overnight in driveway when the glass shattered without any known impact, external force, or evidence of vandalism. The fracture pattern is consistent with spontaneous tempered glass failure originating from the edge, which raises concerns of a potential manufacturing defect or internal stress within the material. On April 20, 2026, I presented the vehicle in person at my local Honda dealership for inspection and assistance. To date, no action has been taken, nor has any resolution been provided. This lack of response is unacceptable given the safety implications. Due to safety concerns, the vehicle is currently not in use and remains parked. I am unwilling to operate the vehicle in its present condition out of concern for further damage or risk. As a result, I am experiencing a significant disruption to my daily activities and mobility. Accordingly, I respectfully request the following: 1. Immediate review and approval of this issue under Honda’s warranty as a case of spontaneous glass breakage. 2. Prompt authorization for repair or replacement of the damaged glass at no cost to me. I have photographic documentation available. Sincerely, [XXX] [XXX] [XXX] ?VIN: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is the fifth time the auto engine shutoff failed to restart after I stopped my car at a stoplight or traffic. This results in potential rear ended accident as one time it stopped in the middle of traffic on the freeway, another time the car behind me at a right turn light that turned from red to green almost rear ended me. No, I brought the car to Honda dealership and they said no problems. But this auto engine shutoff that failed to restart has occurred fifth times. Vehicle has been inspected by dealer and unable to reproduce because they didn’t drive it and step on the brake and have it stopped in middle of traffic. There was an engine warning light that occurred twice but disappeared after 1-2 days before my scheduled dealership appointment. I mention this to dealer. The failure happens suddenly without warning once I step on brake without turning off the auto engine shutoff which I sometimes forget because it is every single time I turn the engine off the auto shutoff would reset. I called Honda America back in January 2026 when I had this problem. I changed my car battery already and so it is not a car battery issue.

NHTSA #11730916

The issue involves a malfunction of the auto start/stop system in my 2025 Honda Odyssey, where the engine fails to automatically restart after coming to a stop. The vehicle instead requires a manual push‑button start to regain engine function. The vehicle and all related components are available for inspection upon request. This failure created a significant safety risk, as the vehicle became unexpectedly inoperative in active traffic. Losing propulsion at intersections or stop‑and‑go conditions exposes occupants and surrounding drivers to the risk of a rear‑end collision or being stranded in a hazardous location. The problem has not yet been reproduced or confirmed by a dealer or independent service center, but it has occurred during normal operation. The vehicle has not been inspected by the manufacturer, police, insurance representatives, or other third parties regarding this specific failure. There were no warning lamps, messages, or prior symptoms before the failure occurred. The issue first appeared without any advance indication.

On 4/4/2026, my child sustained a serious finger injury involving the power sliding door. The child activated the power sliding door using the interior door button. While the door was closing, the child’s hand remained on the front (leading) edge of the sliding door where it meets the door frame (B-pillar). The child’s finger became caught between the closing door and the frame. The power sliding door continued to close completely and latched shut on the child’s finger. At no point did the door stop or auto-reverse, and there was no noticeable slowing, hesitation, or warning indicating obstruction detection. The door operation sounded normal during closing. The child’s finger remained trapped until an adult manually opened the sliding door to release it. The injury involved a finger amputation involving the distal portion of the finger with an open fracture and nail involvement, requiring emergency room treatment. Emergency department records document a diagnosis of fingertip amputation, with radiology findings noting a soft tissue amputation defect and concern for distal phalanx (tuft) fracture of the affected finger. Follow-up evaluation on 04/06/2026 confirmed the severity of the injury and resulted in an urgent same-day referral for orthopedic/hand surgical evaluation.

Auto off system malfunctioning at stoplights. Happened 4 times in 10 days. Remove brake to accelerate and van is no longer in drive. Dash says to depressed brake to engage drive. Do this and will not go into drive. Need to turn vehicle off and back on to be able to place van in drive. One time it would not engage in drive and was able to depress brake and get back in drive but dash kept flashing “brake.” Afraid I will get rear ended at a stoplight

My van is a 25 Odyssey Elite with 18K miles. On several occasions, when I have been stopped at a stoplight and the idle function is activated, the vehicle doesn't auto restart and often it must ben put back into park and restarted. This has worked with a bit of effort. It typically is not just a push of the button but rather some sputtering, several attempts at pushing the ignition button and then and eventual start. Today I had it happen again and had a challenge getting it restarted and this time I noticed that the battery red light came on along with some other warning lights (I don't remember which ones as I was panicking to get going an not hold up the line of cars behind me.

NHTSA #11707843

I stopped at a stoplight and the auto shut off took place, when i tried to take my foot off the brake to start the car, the car did not restart. I stalled at the light with cars behind me and my children, the dash displayed a message saying system problem and flashed I did not get a photo . I shut the car off with the brake and the start button and tried starting it twice, Finally the car restarted and I drove home. Something is wrong with the AIS and it put us in danger

NHTSA #11705502

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.

Category: Structure / Water Leak / Electrical System Risk Vehicle: 2025 Honda Odyssey Description of the Problem: My 2025 Honda Odyssey has a repeated and serious water leak issue that affects the driver-side floor area. I first discovered the leak on October 30, 2025, with the driver-side carpet and foam padding completely soaked. The dealership (Sloane Honda in Philadelphia) kept the vehicle for two days but claimed they could not find any leak. On November 19, 2025, the same leak occurred again, with even more water present under the driver-side carpet and foam. I have photos and videos showing significant water accumulation. This presents multiple safety hazards: Potential electrical short circuits in wiring under the carpet Mold growth affecting occupant health Floorboard corrosion Impaired vehicle operation The vehicle is currently back at the dealership, and Honda has not provided a proper resolution. This is a recurring structural defect that poses a safety risk and should be investigated.

NHTSA #11701182

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.

While idling, the engine shuts off completely and requires the vehicle to be shifted into park and restarted before operation can continue. On multiple occasions, the engine has struggled to restart and cranked for several seconds before turning over. Honda of Tomball in Tomball, TX currently has it. This defect creates a significant safety hazard because the vehicle loses power unexpectedly while in traffic. The vehicle is immobilized until it can be shifted into Park and restarted, leaving us vulnerable to collisions or other accidents, particularly in busy intersections or congested roadways, and creates a serious safety risk to our family, children, and our daughter’s service dog. The vehicle has been presented to HOT multiple times for diagnosis and repair. This defect continues to happen. HOT has inspected this during multiple repair visits. To our knowledge, the manufacturer has not directly inspected the vehicle. (I have requested it with both Honda of Tomball and Honda of America.) No warning lamps or dashboard messages appeared prior to the stalling events. The failure occurs without warning while the vehicle is stopped in Drive. The primary symptom is sudden engine shutdown, followed by difficulty restarting in some instances. This issue began shortly after delivery of the vehicle and has continued intermittently. First documented time of problem was September 2025. Most recent is May 2026.

Starter failed to resume engine operation when auto start/stop disengaged motor at a stop light. This resulted in the vehicle being briefly inoperable after the light turned green, requiring other motorists to go around and leaving the vehicle stalled until engine functionality was resumed. Issue was reproduced by dealership, starter motor was deemed defective and was replaced under warranty. Vehicle had rough starts when resuming from auto stop for at least a week leading up to this incident.

NHTSA #11732345

Upon coming to a complete stop, the engine has failed to reengage causing the car to stall in traffic. The car has restarted after being turned off and restarting but with traffic moving all around us and cars behind honking because they think we are failing to go. If we happened to stop in an intersection it could be even more dangerous. This has happened 3 times so far I. The past couple of months. At first I thought we accidentally pressed a wrong button or did something that caused the engine to stall, but upon research and talking to others with Hondas this appears to be a known issue. I am taking the car to the dealership on 4/10/26 to get looked at. There was no warning light or error messages prior to to happening. We bought the car new and it has only 10,000 miles on it.

NHTSA #11729519

My 2025 Honda Odyssey has had trouble turning on since it has been about 9 months old. It doesn't always turn on from being off. It doesn't always turn on when the vehicle is already on and the auto-start-stop system turns the engine off. More often than not it struggles to start but eventually does. I took it in for service and the dealership replaced the battery. It continued to not start. The new battery did not improve the symptoms. I scheduled another appointment for service and the dealership kept lying and gaslighting me into believing that they did something to improve the symptoms. They claimed to have updated the computer system software/firmware versions. I asked which ones were updated and they said that none were, it was all up to date. They claimed to have "reset" the auto-start-stop system. I asked how that would improve performance when the vehicle doesn't start from being off as well. The vehicle is unsafe to drive. It turns off at stop lights, stop signs, in medians when I am trying to make turns. The engine not restarting in parking lots from a complete stop is also very concerning. I hate and fear my Honda and I am scared to drive it. I have taken it to multiple dealerships to get it fixed and none will do anything. I have a video recorded after this occurred at a red light. The video shows the status of the vehicle and attempts to restart it. This was recorded February 19th 2026.

NHTSA #11726996

Over a period of the last several months when the auto idle stop engages at intersections (red lights, stop signs, etc) the vehicle will intermittently fail to restart. The vehicle stalls entirely and goes into a state where you are unable to restart the vehicle for anywhere from 30 seconds to several minutes. This is a very dangerous situation and each time have had other motorists honking and frustrated that the vehicle is not going when the light turns green. The vehicle is currently at the Honda dealership for the third time to attempt to repair this issue. The first time it was returned to me and I was told no issues found, the second time (after multiple more failures on road) was told the battery was faulty. The battery was replaced but the failures to restart continue. I can see that there are many claims of this same issue with Honda, however in our experience with this vehicle, very little has been done by Honda to solve this major safety issue.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving approximately 40 MPH, the vehicle experienced a loss of automotive power. The failure was intermittent. No warning light was illuminated. The local 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 12,000.

My 2025 Honda Odyssey features a standard Auto Idle Stop system designed to improve fuel efficiency by shutting off the engine when braking to a stop. While intended to restart upon releasing the brake, my 2025 models have reported issues with failing to restart or stalling.

NHTSA #11719763

My Odyssey has a no-restart issue related to Auto Idle Stop. Engineer did not restart at red light and I had to push the button twice. We were caught in traffic and was not safe.

NHTSA #11710551

When the Auto Idle Stop is engaged, I have now had 3 instances of the engine completely stalling when at a stop. Not only has the engine stalled, but I have difficulty getting the engine to restart. It has been very scary, as it has left me disabled at busy intersections while I struggle to get my van to start so I can move and pray nobody hits me while I sit there. I've even had to open the driver's door to get the van to restart. We've made a habit of manually turning the auto idle stop feature off every time we drive it. This problem has not occurred when the feature is turned off. The first incident of this was several months ago, and I already took it to my local dealer but they couldn't replicate the issue and did nothing about it.

NHTSA #11707997

I was stopped at a stop light and the idle stop function activated, turning off the engine, as designed. However, when the light turned green and I released the brake, the vehicle stalled out. I had to completely turn off the vehicle and restart it.

When the vehicle is stopped, and the auto-shut off engages, the vehicle will turn off, and the vehicle has to be restarted. Quite dangerous when in traffic and the vehicle is dead due to the auto-shut off not starting again. The fix is believed to be an updated starter engine computer and starter motor.

NHTSA #11701459

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.

NHTSA #11695782

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.

NHTSA #11691357

I've had several incidents of my car stalling occur since the purchase of the vehicle over the span of 16 months, probably around a dozen times or so. I will stop at a stop light and the vehicle's idle-stop system does not function properly. The vehicle shuts off but does not auto-restart. When I try to manually restart, nothing happens. There have been times where it took several times before the vehicle started back up. Even more seriously, I've stopped in the middle of traffic and the same thing happened. We have had a couple of very scary incidents of cars having to move over a lane to pass our idle vehicle. Thankfully no car hit us due to our idled vehicle. We have owned this vehicle for less than 1.5 years and have had two battery replacements. I've also had the vehicle not start from my garage or parking lot. When I try to start the vehicle a second time, there are times where the start button feels very firm and doesn't push down easily. I have to push the start button several times before the vehicle starts. I'm grateful there have not been any major accidents occur but this is an extremely unsafe situation for the driver and their passengers.

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.

In January 2025, we drove to Florida from Michigan. When I started my car every signal light came on. It would not allow me to shut down. We drove it to Orlando Honda and they said the sensor light was covered with road salt. It was very scary. In November 2025 we were driving home in a snowstorm. The sensor in the front got covered and shut down the speed control, warning lights of crossing lane, detecting cars on right or left. I get told every time can’t duplicate. The automatic bright lights got stuck on after only a month of having this car. Dealership says it was off. Well it wasn’t and they still do not work. Speed limit sign on dashboard will go up to 85 miles per hour this is in a 25 mile area. Again they say can’t duplicate. Brakes feel mushy to myself and husband. Again we’re told there is nothing wrong with it. When the speed controls are set there is at least 2 miles difference with my Waze speed and the vehicles speed. I’m told this is normal. Well it’s not. Something is wrong with the electrical system. I owned a Honda Odyssey before and I never had any issues with that one. We’re getting ready to drive to Florida and I’m terrified the system will shut down again. I was told that having road salt on a sensor is not a warranty issue. Well, it is because of poor design. I’m also afraid once this vehicle is no longer under warranty I will be paying $ for this poor design. I’m not happy and now wish I had my old one back.

The idle stop feature sometimes fails to reengage / restart the engine. One time, the van failed to restart and the vehicle completely locked up while I was in an exit ramp to the freeway. I had to turn the van off and turn it back on to get it to shift into drive and go. Similar events have happened a number of times, since the summer of 2025. We have taken it to the dealer twice now, and have been told to "monitor" it. We found the NHTSA report #EA25004 and believe this is the issue we are experiencing. Occasionally, the idle stop will restart, but it's a very violent restart (car sputters and chokes in restart, sounds like it might stall). The car will make a warning light flash and give an error message, but it always clears too quickly to read it.

NHTSA #11714864

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 to be able to get back into Honda. The vehicle has only been looked at by my local Honda dealership. There were no warning lamps, messages, or other notifications prior to the failure. I received a warning on the dashboard after the events occurred on how to start the vehicle. This is very disappointing as a new Honda owner. My husband and I decided on Honda over other car companies due to their reliability and this has now become a constant worry.
