2024 odyssey engine shut off while in drive thru at restaurant. Unshure if auto start stop override was active. Either way the van had to be re started using the start button. Van re started on second or third attempt to re start with start button. This is a repeat occurance since having starter replaced in response to a similar problem about a year ago.
Car purchased July 4, 2024. Idle stop/start was working but after several months, it became defective. After driving for some time, idle stop/start wouldn't work properly and cut the engine off when idling. I would have to turn the car, open my door, and try to restart the car. It also occurs after parking, turning off the car and less than 10-15min attempt to restart. Most of the time, it'll start after 1 or 2 attempts. Except today 07/31/2026, I got home and parked. After 20min, I tried to start my car and after 10-15 attempts, it wouldn't start. After waiting 2 hours, the car finally started.
The contact owns a 2024 Honda Odyssey. The contact stated that while the vehicle was parked and attempting to place her [XXX] child in the rear passenger’s side seat, the contact touched the door handle, unlocking the door, and placed the bag with the key fob on the floor of the rear passenger’s side. The contact walked around to the driver's side door, and the door was locked. The contact returned to the rear passenger side of the vehicle and became aware that the door was locked. The contact attempted to enter the vehicle but was unsuccessful. The contact called the Fire Department, and the front passenger window was broken to enter the vehicle. A Police report was taken, but the information was not available. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,000. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
From a cold start my vehicle starts fine, but from a warm engine start the van would have trouble starting. Took it to Navarre Honda in Lake Charles, La and they found that the starter solenoid and 2 relays were bad and had to be replaced.
My minivan has had repeated electrical and safety-related failures since shortly after it was leased. The vehicle has died or failed to start five times, including multiple tow events. The first battery failure happened shortly after delivery, but we thought a light may have been left on and did not know to bring it in. The problem continued. The dealer has replaced the battery, recharged the battery, replaced the alternator, and later found an excessive parasitic draw, but the electrical problems have continued. The failures affect more than starting. The sliding doors have failed 30+ times by refusing to close and acting like something is blocking them when nothing is there. This creates a safety concern because passengers may not be able to safely enter, exit, or secure the vehicle. The instrument cluster has gone black on startup in Park about 10 times and has also blacked out or faulted while in use. A brake failure warning light appeared once. The backup camera intermittently dims so badly that I cannot see behind the vehicle while reversing. A service advisor observed this issue, but the technician could not reproduce it during inspection. The DVD/interior electronics, USB charging, and wireless phone charger have also failed. The power tailgate/trunk malfunctioned repeatedly before repair, including problems opening or closing and clicking. The front driver and passenger windows also do not roll down smoothly. The front window still shakes or drags even after two repair attempts. The vehicle has been inspected by authorized service centers and is available for inspection upon request. The exact root cause is unknown, but based on the repeated dead battery, charging, parasitic draw, door, display, camera, brake warning, interior electronics, and power window failures, the pattern appears consistent with an unresolved electrical or charging-system defect.
My 2024 Honda Odyssey has repeatedly failed to restart after the Auto Idle Stop system shuts the engine off at a red light. When I release the brake or press the accelerator, the engine does not restart as it should. The vehicle then shifts into Park or instructs me to place it in Park, and it is difficult to restart using the start button. This has left the vehicle disabled in an active traffic lane and creates a serious risk of being struck by another vehicle. I have been stuck at a red light with people honking at me and haven't been able to start the car for up to a minute. The problem is intermittent, and I do not know whether it is caused by the engine, electrical system, battery, starter, software, or power train. The Auto Idle Stop system should not shut the engine off if the vehicle may be unable to restart.
The Start/Stop function on the Honda Odyssey failed to re-start the vehicle after it was stopped at a traffic signal. The vehicle gave no advance notice of the issue. The vehicle defaulted the transmission into the "Park" position, however the electronics (radio, windows, etc.) all operated as normal. Simply pushing the ignition "On/Off" would do nothing and would NOT turn off the electronics. I had to press and hold the "On/Off" ( similar to a Ctl+Alt+"Delete") to hard shut off the vehicle entirely. I then had to place the key fob physically on the "On/Off" button to restart the vehicle. This is a significant safety concern being at a dead stop at a stoplight that may be green. We have had our van to the Honda dealer twice now within 3 weeks for the same issue. They cannot get it to duplicate any issues. The original diagnosis was that we had a loose ground connection at the battery. The battery, alternator, and starter were all diagnosed as in perfect working order. The tech tightened the loose ground, but the issue has not been resolved. There were zero warnings that there was an issue with the start/stop function.
The vehicle has an automatic stop/start feature that is enabled by default, though there is a button readily accessible to deactivate the function easily ea. time the vehicle is operated. The vehicle has just had the starter replaced under warranty @ 25K miles. There have been issues with the vehicle struggling to start for at least six months now - rough, slow starts where the engine is struggling to turn over. If I forget to turn off the auto-start/stop function, the engine will sometimes shut off at a red light - but it won't turn on again when the light turns green and it's time to move. I have had this happen a handful of times in traffic - the engine turns off and will not restart when normal procedures are followed.
Had to replace starter at 29,000 miles due to auto stop/start prematurely wearing out component.
The vehicle is experiencing an Auto Idle Stop (AIS) failure to restart from a complete stop. The engine dies, the electrical system resets, and it requires a manual button push or jumpstart to get moving again
Last week, I opened my vehicle door and noticed water standing in the foot well. I didn't think too much of it until I started driving down the street and gallons of water were gushing on my feet in the footwell from behind the steering wheel and fuse box. I parked and waited for it to dry out a few days. I took my vehicle to the dealer and was shocked to hear that this is caused because the sunroof has a drainage system, and when the primary drain clogs, due to pollen or dirt, the secondary drain drains directly into the driver footwell. They advised that this is an issue that disregards vehicle age and sunroof non-use. Because this is a new vehicle, all of my basic maintenance and inspections have been provider by the Honda dealer. I asked why this had not been inspected on my previous service appointments and was told the primary drain for the sunroof can only be inspected by camera. It is only when the primary drain becomes clogged that the water dumps into the driver side footwell. I searched my owner manual and found nothing to indicate or require that the primary sunroof drain should be inspected, cleaned or serviced, at any of the maintenance intervals, and especially not during the first 2 years of ownership. The steering column, fuse box, and driver footwell house all of the necessary electrical and mechanical parts for steering, braking, acceleration, lighting and all other electrical systems controls. Additionally, if this were to happen while driving, the distraction to the driver could be catastrophic. My vehicle has been at the dealer for a week to clear the clog in the primary sunroof drain, remove the seat and carpet to dry, & inspect the electric systems including the power seat. I can make the vehicle available for inspection as needed and the dealer can provide the camera inspection that diagnosed the issue. This happened due to everyday dust and pollen, and there was no advance warning that this drain failure was imminent.
Automatic start stop completely turns off car when pulling up to a stop sign, light, or yield intersection. Car completely turned off and wouldn’t start on a bridge overpass causing a safety hazard. Took a solid minute for it to restart.
Since purchasing my 2024 Odyssey EX-L I have experienced on multiple occasions where the idle stop engages but upon releasing the brake the vehicle fails to restart, dash lights up and vehicle is shifted automatically into park while sitting in traffic and vehicles moving all around me as well as honking as I am unable to restart the vehicle immediately. I have to push the start button multiple times before the vehicle will restart. Dealership is unable to replicate issue so I just started turning it off. Now the idle stop/start doesn't engage at all even after driving for hours. Additionally the vehicle is very slow to start especially if I have had to start the vehicle a different times throughout the day. I took the vehicle back to the dealer and they diagnosed it with a bad starter at only 38K miles which is of course out of warranty. Not only is this a safety issue of the vehicle stalling in traffic but Honda is failing to recognize a well known issue with the starter in this particular vehicle, sticking consumers with hefty repair bills for a manufacturing issue.
For the past year, the vehicle's Auto Idle Stop system has intermittently failed to restart the engine after coming to a complete stop at traffic lights. This creates a dangerous situation where the vehicle is immobilized in active traffic, posing a significant risk of rear-end collisions or other accidents. I have taken the vehicle to an authorized Honda dealership for service; however, they were unable to duplicate the issue and declined to perform further repairs. As the problem remains unresolved, I am reporting this incident to the NHTSA to contribute to the official record of safety concerns regarding this feature in Honda vehicles.
My 2024 Honda Odyssey EX-L has a recurring Auto Idle Stop failure. About 1–2 times per week, when stopped at a light and Auto Idle Stop engages, the engine fails to restart properly when I release the brake. The engine sputters or shuts down, the battery warning light comes on, and the vehicle shifts itself into Park. I then have to hold the start button for several seconds to restart the engine. This creates a safety risk because the vehicle becomes disabled in active traffic when the light turns green. The vehicle was previously taken to a Honda dealer for this issue, and the battery was replaced, but the problem continues.
2024 odyssey sport vin [XXX] in the drive through lane at a reataurant activated the auto start stop feature and shut off the van.

My car is experiencing the starting issue that is listed as auto start/stop feature. However, since I almost always have the AC on or start/stop disabled because the car will not start when hot after a few stops and was scared it would do it in traffic. So far I can get it started again but need to completely turn car off and try again, sometimes more than once. Had been going on for a year and the dealer has replaced battery then the next services said nothing wrong. Now the car is out of warranty and the starting issues getting worse and have finally found online that others are experiencing similar issues. I have forgotten to turn off start/stop a couple times and been stranded in traffic as well when car auto stopped at red light and did not restart causing me to be stuck until i could get it restarted.
The contact owns a 2024 Honda Odyssey. The contact stated that while driving at an undisclosed speed, and while stopped at a red traffic light, the Automatic START/STOP system failed, causing the vehicle to unexpectedly shut off. The vehicle was restarted and drove normally. On another occasion, while stopped in a drive-thru, the vehicle shut off unexpectedly. The emissions system, adaptive cruise control, and tire monitoring system warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with battery failure. The battery was replaced; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 22,000.
The idle stop on the van will stall the vehicle. This has happened 3 separate times where the vehicle stops, then stalls when the engine tries to turn back on. This can be very dangerous, especially when trying to turn from an intersection and the vehicle stalls.
"The vehicle is experiencing an intermittent, loud popping/crackling noise coming from the speakers and infotainment system. This is a known symptom of a failure in the MOST (Media Oriented Systems Transport) bus network, specifically related to defective FAKRA connectors and coaxial cabling. This issue was previously the subject of NHTSA Recall #23V-431 for 2018–2023 models, but the defect persists in this 2024 model." Safety Risk: "When the MOST bus network loses connection for more than 20 seconds, the infotainment screen freezes or goes black, causing a total failure of the rearview (backup) camera image. This failure occurs unpredictably while the vehicle is in reverse, significantly increasing the risk of a back-over accident or collision. Additionally, the loud, sudden popping noises are a severe driver distraction." Dealer/Manufacturer Response: "The Honda dealership confirmed the issue is consistent with the known MOST bus failure (TSB 23-047). However, because the vehicle has 49,000 miles, both the dealership and Honda Corporate (Case # [Insert your number if you have one]) have denied a goodwill repair, despite this being a documented safety defect that has been the subject of prior federal recalls
The contact owns a 2024 Honda Odyssey. The contact stated that while stopped and using the Auto START/STOP feature, the vehicle failed to restart as designed. While attempting to restart the vehicle, the battery warning light flashed on the instrument panel. The vehicle restarted after several minutes. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 41,000.
The vehicle was stopped at a red light. This vehicle is equipped with an auto-start/stop system to save fuel. Once the red light turned green the engine refused to restart. This was the second instance. The vehicle took over 30 seconds before it would restart. None of the push-to-start buttons worked, the car would not recognize that the brake was pressed, and it had also shifted itself into park. Very dangerous while traffic was moving all around us.
I believe something is wrong with the electrical system tied into the infotainment system of the car, which displays the radio, heating, cooling, shows the rear camera controllers, as well as some fo the lighting in the sport L is not fully lit, for example where the shift gears is there a light that goes across the front, mines if red, only 1 side is actively turninig on, but the other side is off, at time the display become unresponsive, meaning no matter what I select nothing is displayed I only get the main screen that shows the FM/AM, CAR PLAY, Andriod Auto, Setting etc, when this happens and when the screen flickers the radio does not turn on, no sound is heard, I can turn on/off the ac, but can control where the air flows, or changing some basic settings, at times the rear camera will not work as well. I have videos of this for my records, and I did report this directly to Honda, but they indicated there is no recall for the infotainment system, I previously had a 2021 Odysessy and there was a recall for soemthing very similar, not sure why they would continue to use the same system in the newer vechiles, clearly something is wrong here, so I am documenting this for my records, but I believe Honda needs to step in and correct this issue before other electrical problems occur and someone gets injured
Automatic Idle Stop function fails. The car idles down while at a stop and then the entire car will shut off and fail to restart. This occurs frequently at stoplights, stop signs, in traffic or any time the vehicle idles down. The car fails to restart right away resulting in multiple attempts to start the engine and poses a danger to occupants in traffic.
The vehicle will shut off at stops after the auto idle stop engages. We have to turn the vehicle back on and press the "off auto idle stop" button to not have this happen. I will enter the last date we noticed this below.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
