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.
completely shuts off during an idle stop at a traffic light
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.
The idle start stop system on my 2024 Honda Odyssey sometimes works, and then other times will leave me stranded at a stoplight, making it a grave safety concern. After the engine does not restart you have to turn the car completely off put it in park turn it all the way back on and then continue driving. This is not related to any of the climate controls being onto high or energy being consumed. It seems to be a manufacturing 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.
Several times the vehicle has turned off due to the auto on/off and did not restart. No warning. This happened two times at intersection near school with multiple children in the vehicle. Vehicle was not able to restart immediately. Changed to a new agm battery and still does not work. Trouble starting. Slow starting and combined with auto on off this is a dangerous disaster of vehicle
While driving in normal traffic, when I come to a complete stop and keep my foot on the brake, the Auto Idle Stop system activates as designed. However, when I release the brake to continue driving, the engine intermittently fails to restart properly. Instead, it repeatedly attempts to restart, cycling on and off several times before shutting down completely. When this occurs, the vehicle becomes disabled in traffic and does not respond as expected. It can take multiple attempts and a significant amount of time before the engine finally restarts, leaving me stranded in intersections or in moving traffic. This creates a serious safety hazard because surrounding vehicles continue moving while my vehicle is unable to move. This problem has occurred multiple times under normal driving conditions and is not an isolated incident. During one occurrence, the vehicle failed to restart after the Auto Idle Stop system activated, leaving my vehicle disabled in traffic. As a result of this incident, my vehicle was involved in a collision that **damaged the front and back bumper**. Fortunately, no one was seriously injured, but the incident clearly demonstrates the significant safety risk associated with this defect. The vehicle is currently at an authorized Honda dealership for diagnosis and repair. I am submitting this complaint because a vehicle that unexpectedly shuts down and fails to restart after Auto Idle Stop activation presents a serious safety hazard. I am concerned that this defect could lead to additional crashes, property damage, or serious injuries if it is not corrected.
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
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.
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.

SEVERAL TIMES, I HAVE BEEN DRIVING, AND THE AUTO STOP SHUTS THE ENGINE DOWN, THEN IT WILL NOT RESTART. THIS HAS HAPPENED ON A VERY BUSY STATE ROUTE IN THE MIDDLE OF AN INTERSECTION, WHILE I HAVE MY YOUNG CHILDREN IN THE VEHICLE. THIS IS VERY CONCERNING AND A MOJOR SAFETY ISSUE FOR US.
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.
Car doesn't start, has needed to be jumped almost 20 times in a year. Auto start stop has shut the car off in intersections
I have had multiple issues with the radio (16000 miles). After many personal videos dealership was able to fix one of this issues with a new part (22000 miles). I was informed the other issues I was having with the radio was due to my battery not staying fully charged. I was also having issues with the van not starting right away, which made me feel I could get stranded. It took many attempts to get the van to start. The van also wouldn't let me reverse one time, with a message telling me to place van in park. Another issue is the van is very slow to restart from auto idle shut off. The transmission is slow to change gears in lower gears and the van jerks a little bit. Next my rotors were warped. I was informed by the dealership that there was nothing wrong with my transmission and the auto idle down was working properly. NO one could explain the rotors being warped. They reshaped my rotors and replaced the battery and told me they hoped that fixed the problem. Well indeed it did not fix the problem. As of 12/27/25 the van completely shut off at a stop sign and again on 12/28/25. The issue is only getting worse (24,000 miles) and now I am scared to death that the van will stop while i am driving. The dealership has been contacted and I am waiting on a call back for a loaner car. I was in traffic and was extremely worried about my safety, as well, the safety of others around me and with me. ( Side note I returned the van to another dealership soon after the first dealership performed work on the van, when I heard a metal on metal sound and what sounded like a bolt rolling around in my back brakes. They did not find anything wrong but were also puzzled by the rotors already being warped. I was afraid to make the trip to the orig dealership). I have recently gotten a video of the brakes scraping again. This van is causing a lot of safety issues for my family.
The start stop system has failed to restart at a busy traffic light more than half a dozen different times after a 1 hour drive. Short drives do not bring this issue out. This got me stuck at a light, drivers annoyed honking and confused as I try to get my vehicle to start again. Turning the van completely off and back on again seems to get the van to restart again. I tried bring the issue up to the dealer when I brought it in for its first service, but the employee was extremely rude/belligerent and stated they would only do an oil change when I asked for help with this safety issue among other things. Will take to another dealer next service interval and try again. No issues known or warning lights on the vehicle prior. The van when it did this, error'd stating failure to restart or something along those lines. It happened so fast I don't 100% recall. After the issue the van would have no issues or lights on at all to even think anything had went wrong in the first place. This is a 2024, purchased new, vehicle.
The Auto Idle Stop (AIS) feature on our 2024 Honda Odyssey EX-L has recently failed to restart engine leaving driver and passengers stranded in heavy traffic at intersection traffic lights. This has occurred twice, once while traveling alone, once while traveling with five year old child. Safety put at risk because driver had to exit car in middle of road during rush hour traffic while cars attempted to go around. The problem has not been reproduced or confirmed by dealer. Had battery tested at auto parts store and results indicate battery in good condition. Vehicle has not been inspected by the manufacturer, police, insurance representatives. There were not any warning lamps, messages or other symptoms of the problem prior to the failure.
While operating the vehicle, I have experienced repeated problems with the idle stop/start system. Specifically: 1-The engine automatically shuts off at stop signs and stop lights as designed, but at times the vehicle fails to restart immediately when the brake is released or the acceleration is pressed. 2-Multiple occasion while stopped in traffic the vehicle unexpectantly shifted into "Park." 3-For the last 3 weeks the vehicle sometimes hesitates to start on first attempt.
The contact owns a 2024 Honda Odyssey. The contact stated that while at a stoplight, the auto idle stop feature malfunctioned, and the vehicle failed to immediately restart after releasing the brake pedal. On several occasions, the vehicle had to be shut off before restarting. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The contact was informed of the NHTSA Action Number: EA25004 (ENGINE AND ENGINE COOLING); and related the failure to the campaign. The manufacturer was not yet contacted. The failure mileage was 8,500.
On multiple occasions, the idle-stop function engaged at a red light and then either the entire car shut down or the computer froze for a minute or two then restarted. For each incident, we had cars behind us that either nearly hit us when we did not go forward when the light turned green or nearly hit us by aggressively going around us while we restarted the engine.
The 2024 Honda Odyssey has an idle-stop feature which is hesitating too much and risking stalling at intersections. Honda tried to blame it on the battery but even Honda has tested the battery as fine. The 2025 model has a software fix to disable the idle-stop when the AC is running hard and this would fix the 2024 but they claim to have to fix for the car. This is dangerous to be stalling at major intersections and many Honda and Acura vehicles have had and many still have this problem. Remembering to disable the control every time one starts the car is NOT a fix. Please help get this problem for 2024 Honda Odyssey’s fixed before someone gets injured or worse trying to restart a car when it keeps stalling
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.
