The AIS system does not start back up at a light. Sometimes throws itself into park. Last week it started up, but everything shut down about 75 after the traffic light. The entire car loss all power. In the middle of traffic. Needed a policeman to wave cars around e in the middle of the street. Took to the dealership; they kept it for two days and could not recreate the situation. The car had the same problem with start up two days later after leaving the dealership
2025 Honda Odyssey electrical complaints
Page 5 of 9: complaints 101 to 130 of 243, newest first, as owners wrote them.
Starting problem. The vehicle sometimes (randomly) refuses to start after shutting off. For example, after filling gas, or turning off (idle off) at a stop light. It just refuses to start. Terrifying. Researched on the Internet and found thousands of complaints about this going back years. This needs a recall.
I was driving on a road around 30 mph when the engine cut off and shifted itself into park. No warning, no power, no movement. Car was dead in the road and I was unable to move it to the curb. I tried to press the drive button. Nothing. i pressed the starter button. Nothing. Parkway Honda said they could find nothing wrong other than replacing the battery. Car is brand new. Bought used at 6,000 miles and have only driven it 4,000 additional miles in roughly one year. Very dangerous defect for which they have no explanation.
Internal starter failure.
The contact owns a 2025 Honda Odyssey. The contact stated that on four occasions while stopped at an intersection with the engine idling, the idle stop feature activated, and the vehicle unexpectedly shut off. The mechanic was able to restart the vehicle. There were other drivers behind the vehicle who started honking their horns. Several unknown warning lights were illuminated on the instrument panel. The vehicle was taken to a local dealer to be diagnosed. The dealer inspected the vehicle and determined that the battery and starter needed to be repaired. The battery was replaced. The manufacturer was not contacted. The failure mileage was approximately 22,000.
Idle stop and restart problem: After stopping , the engine shut off and won't be able to restart. Happened multiple times even after the Honda services department re-programmed it.
When the van is turned off it does not want to start easily again. This has now happened approximatly 5 times. I had the battery checked at O'reilly's and the battery was fine but the starter was not.
Our 2025 Honda Odyssey has repeatedly shut off or failed to restart while stopped. This has occurred approximately 10 times. The vehicle was previously taken to an authorized Honda dealership for this issue. The dealership diagnosed the battery as the cause and replaced it, but the same problem continued afterward. The two most recent incidents occurred on 7/21. During one incident, we were stopped at a red light on a road with a 55-mph speed limit. The vehicle shut off and did not restart normally when traffic began moving. We were left immobilized in an active traffic lane while vehicles approached and passed us at approximately 55 mph. We had difficulty getting the vehicle restarted and moving again. This presents a serious rear-end collision risk because approaching drivers expect traffic to move when the light changes. Four children regularly ride in this vehicle, and we do not believe it is safe to continue driving. We contacted the Honda dealership again after the battery replacement failed to correct the problem. We were told that unless technicians could duplicate the issue, there was nothing further they could do. Because the failure is intermittent, we cannot predict when it will occur, but it has happened approximately 10 times and has continued after Honda’s attempted repair. We also opened a case with American Honda Motor Co., Inc. We are reporting this because the vehicle can unexpectedly leave our family stranded in an active traffic lane and unable to move out of the path of approaching traffic.
My 2025 Honda Oddessy with only about 31,000 has stalled in the last 2-3 months about 5 times at stop signs/stop lights. It throws itself in park and doesn't recognize that I'm pushing any buttons. On the dash it only says "press the brake" which I am doing. I called Victory City Honda in Michigan City, IN [XXX]) and arranged a diagnostics check on XXX. They said it wasn't throwing codes and didn't replicate when they test drove the vehicle. If I turn off the auto start/stop it doesn't seem to happen but if I forget to push this button each and every drive - it stalls and won't start for up to 10 minutes. Once we were parking at home and it would not allow us to shut the vehicle off. Upon research I found the federal safety agency investigation ID#XXX with the exact problem I am experiencing. I called my Honda dealor to report and they stated they are not able to do any software updates without a Honda recall. I have another appointment with them on XXX to check the battery and possibly the brake pedal sensor. Please help.

2025 Honda Odyssey with approximately 22,000 miles. On multiple occasions while stopped at traffic lights or stop signs, the vehicle's Auto Idle Stop feature shut the engine off normally. When I attempted to accelerate, the engine failed to restart, leaving the vehicle disabled in the travel lane. The battery warning light illuminated, and on one earlier occurrence I believe a "Shift to Park" message may also have appeared. I was able to restart the vehicle by pressing the Start button, shifting back into Drive, and continuing normally. The most recent incident occurred while stopped at a traffic light. When the light turned green and I pressed the accelerator, the vehicle did not restart or move. I had to manually restart the engine while stopped in the intersection before I could proceed. This created a safety concern because the vehicle unexpectedly became disabled in active traffic. The vehicle has never exhibited difficulty starting during normal operation, either when cold or warm. The problem has only occurred after the Auto Idle Stop system shut the engine off at a stop. The vehicle has not yet been inspected by a Honda dealer, but an appointment will be scheduled.
After AIS engaged, the engine wouldn’t come back on. This has been at intersections, etc where it was dangerous to have no engine. It is ridiculous that the feature has not been removed after problems going back to the 2018 model. All to game an emission standard. Shameful.
Vehicle failed to start occasionally, which could be a hazard with the auto start/stop feature. Issue was confirmed with dealer and corrected under warranty. Starter was replaced.
auto idle stop/start system malfunctions intermittently. The car will shut off at a red light/stop sign then will not automatically restart. Will require shifting to park and restarting the car at the intersection.
When stopped at a red light today, our minivan's Auto Idle Stop (AIS) system stopped the engine with the brakes depressed (as advertised). Once the light turned green, the driver released the brake to re-engage the motor, but the starter did no restart the minivan and a battery light flashed on. The start button had to be pressed several (~4) times to get the motor to restart and to turn the battery light off.
This has been addressed by the dealer once before and the starter was replaced, however the problem is happening again. The auto start/idle feature will not start the car back up while stopped on occasion. For instance, yesterday while stopped at a red light the auto idle/start feature kicked in, as expected. When releasing the brake to drive when the light turned green the car beeped and would not start again. We had to power the whole van down at a busy intersection and restart. Thankfully it started. We didn’t catch what warning lights flashed when the van beeped, but no warning lights were present before the issue. As mentioned, this has happened before to the point the dealership replaced the starter. But unfortunately, it is happening again. The van often has a rough start as well when using it, but not every time.
The vehicle experiences dangerous, unexpected engine stalling immediately following an Auto Idle Stop event. Upon coming to a complete stop at intersections, the engine shuts off as designed, but fails to automatically restart when the brake pedal is released. The vehicle completely locks up, leaving my family stranded in live traffic and requiring a manual reset of the ignition, which takes time to restart several minutes or longer. The local Honda dealership states they cannot duplicate the intermittent issue, posing a severe ongoing safety hazard. Honda has a ticket open for the year of my Honda but has yet to approve or make a fix. It's happened several times first notice it back on XXX and Honda dealer could not duplicate the issue so they did nothing. It has happened several additional times before now but this last time it happened XXX we were on a highway at night and it almost caused us to be rear-ended. The first times it happened back in XXX I sent them a photo of the dashboard light up when it was stalled, but they said they couldn't duplicate the issue and did not fix anything. This was all done through First Texas Honda in [XXX], which is where the vehicle is at now. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I bought a brandnew vehicle 1/31/2025 and it was a White Honda Odyssey 2025. I was in search of a bigger and safer car for my family of 5. Within months I had major issues with the vehicle. I would bring my car in and it would get returned unfixed. My vehicle has now gone in for a 6th time (twice in a week) for service for shutting off while the vehicle was IN MOTION (on the highway , busy rotary and roads) I have spent hours and hours and hours speaking to people and James Brown at Parkway Honda. I have been lied to about how much my vehicle was driven and tested with them not knowing I had tracked the mileage on there at dropoff and checked at pickup. I feel very small in this situation as Parkway Honda keeps brushing me off and not fully getting that a vehicle shutting off while in motion on a highway or in a busy rotary is wildly unsafe. My kids and I have been SOO lucky that this has not been fatal. Honda keeps saying it's the battery, etc. My car was in there for over 3 weeks last Summer for this issue and has been in and out multiple times and it was brand new. This is criminal on their part and they know they are bigger than I am and im sick of it.
My vehicle has experienced repeated unexpected engine shutdown/no-start events, creating a significant safety hazard. The engine has unexpectedly shut off or failed to restart while stopped in traffic and while entering traffic, resulting in a sudden loss of propulsion. On one occasion, the vehicle would not restart for approximately one minute. The vehicle was inspected by an authorized Honda dealership, and the starter was replaced under warranty in July 2025. The repair did not correct the problem. Since that repair, the same failure has occurred multiple additional times. The issue has now occurred at least six times over approximately one year. Because the condition is intermittent, the dealership has not permanently identified the root cause. The vehicle is currently being returned to the dealership for further diagnosis, and I have requested that the matter be escalated to Honda Technical Assistance (Tech Line) and Honda Engineering. This defect creates a serious safety concern because the vehicle can unexpectedly lose power while in or entering traffic, increasing the risk of a collision. There were no consistent warning lights or messages before the failures, and the condition occurs intermittently without warning. The vehicle remains available for inspection.
The contact owns a 2025 Honda Odyssey. The contact stated that while stopped at a red light, the message "Severe Damage Alert" was displayed on the instrument panel. The accelerator pedal was depressed and the auto idle stop feature engaged, and the vehicle stalled. The failure had occurred on several occasions. A dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.
WHILE STOPPED AT TRAFFIC LIGHT, ais cuts off engine but stall engine, won’t stray immediately. Have to cutoff engine and restart. Takes several tries to restart. Has happened several times over the last 6 months.
My 2025 Honda Odyssey intermittently fails to restart after the Auto Idle Stop system shuts the engine off at traffic lights or stop signs. When I release the brake to proceed, the engine does not restart as it should. Instead, the instrument cluster displays messages such as “Shift to Park to Restart” and/or “Press Brake to Start.” At that point, the vehicle is immobilized in traffic and I must shift into Park and manually restart the vehicle using the Start/Stop button before I can continue driving. The problem occurs intermittently, making it difficult for the dealer to reproduce. It appears to happen more frequently when the air conditioning is running, although it has also occurred under other conditions. This creates a significant safety hazard because the vehicle can become stranded in the middle of an intersection or at a traffic light, exposing occupants to the risk of being struck by other vehicles. I took the vehicle to a Honda dealer, but because the condition could not be reproduced during the visit, no repairs were made. The issue continues to occur. I am reporting this because the failure of the Auto Idle Stop system to restart the engine presents a serious safety concern and appears consistent with reports from other Honda owners.
There is an idle function on the engine that shuts the engine off when at rest, the engine has failed to restart and the car dies in the middle of the street, without warning, as if the battery is dead. The handful of times this has happened the car has been able to start back up within two or three tries. Honda acknowledges the issue as far as I know. The dealership let me know this is a known issue. It is unacceptable that there is no fix to this problem.
The contact owns a 2025 Honda Odyssey. The contact stated that while attempting to accelerate from a complete stop occasionally, the vehicle hesitated while the accelerator pedal was depressed. No warning lights illuminated. In addition, the contact stated that while Eco mode was activated, the failure occurred more consistently, causing the air conditioning to fail to power on in hot climates. The contact stated that the failure became persistent. The vehicle was taken to a local dealer, who diagnosed that excessive heat caused a starter seal failure, and the vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 16,598.
Stopped in heavy traffic in a four lane highway. Auto start/stop shut the engine down as expected. Traffic ahead cleared. I took my foot off of the brake to step on the gas. The engine didn't start up, and the radio and all lights inside went blank. Traffic behind me approached at about 45 mph. and were swerving around to avoid hitting my dead vehicle from the rear. I pushed the start button. Nothing. Again. Nothing. Several times more with my foot on the brake, or off the brake. Nothing. I put it in park and kept trying the start button. Finally it started, the radio and dash display came on, and from then on it operated as usual. Scared the hell out of us. There was no warning that anything in the car was malfunctioning before this happened. Took it to the dealer. They looked it over, kept it overnight. Told me the next day that the battery can get drained too much if the air/cond is on max and the start/stop feature doesn't like that. They used a machine to drain the battery and recharge it and they tell me now that it should be good. I don't believe one has to be aware not to use the air on max while the start/stop is enabled. I'm afraid to drive the car now! Our lives were in danger.
The vehicle suffers from an intermittent electrical/charging and starting system failure tied to the Auto Idle-Stop feature. While driving and coming to a stop at active traffic lights, the engine stutters and completely shuts down. It then fails to automatically restart, requiring multiple manual attempts to crank the engine back over. This creates a severe safety hazard, leaving my family suddenly stranded and vulnerable to being rear-ended in live traffic. The vehicle also intermittently struggles or takes multiple attempts to start after being parked in lots. The issue has been brought to two separate authorized Honda dealerships within a 30-day window. The first dealership diagnosed a failed battery and replaced it under warranty, but the stalling recurred. The second dealership held the vehicle for five days for diagnostic testing but stated they could not replicate the defect, returning it with no repairs made. Immediately upon picking the vehicle up from the second dealer, it suffered another starting failure in a parking lot. No warning lamps or error messages appeared on the dashboard prior to these failures. The components are intact on the vehicle and available for inspection upon request.
1st concern- while in an intersection the van powered off after lights on dashboard said something about a system failure. I tried restarting vehicle several times as I was really nervous being in an intersection and it finally started after a few tries. This same thing happened l, to my husband, while parked in our garage about to leave. 2 nd concern- last week on XXXI drove to [XXX] for a short vacation and while at a stop the dashboard had multiple warnings going off 1) electrical power steering system problem 2) Hill start assist problem. Vehicle may roll upon brake release 3) adaptive cruise control problem 4);power steering system problem. I called Roadside assistance and we waited about an hour and a half. He used a tester and said all was coming back fine but to take van to a dealer the next day. We took it to Egg Harbor Honda dealership and they said if the codes have cleared, which they had, then there is nothing they can do and to just take it to our dealer when we return home. I have an appointment for tomorrow at XXX at 915 am at [XXX] of Honda in Abington, PA. I have pictures of all the "2nd concern" warnings. During the 1st concern I was driving and did not feel comfortable capturing the warning lights with my phone camera.

When stopped at a stop light, the car went into idle stop. Upon taking my foot off the brake to accelerate, the car stalled and required me to push the brake and ignition button to shut it off completely and then restart the car. This has happened on 8 separate occasions. It seems to happen more frequently when we have the AC on on a hot day. It's scary to be at a light with cars waiting to go around you sometimes in the middle of a busy road and your car just stops. I feel anxious when driving on the highway that the car will just stop, though I think that is unlikely given how this happens. We have gotten into the habit of turning off the automatic idle stop feature when we drive and that gets around it, but you have to shut this off every time you start the car, so we forget sometimes. No warning lights before the failures occur nor after. We are going to visit the dealership, but this is a known issue that is already under investigation and so I am just adding our report to the pile of others as additional evidence.
We purchased a brand new 2025 Honda Odyyssey in Nov. 2024. Within a couple months of owning our new vehicle we began having issues with the Auto Idle Stop system. The vehicle will not turn back on at random when stopped at any time when driving. This is a huge safety risk as this has often happened while stopped at a light. It’s also happened when in the drive through. Essentially any time stopped to then go from the brake to the gas. There are times I can get the vehicle restarted quickly and other times it just won’t turn back on for about 30 seconds. The battery light flashes at times when this happens, but not consistently every time. The screen also shuts off and all power to vehicle until I get it restarted. I have had moments where I thought someone was going to rear end me. This issue occurred three or more times prior to our vehicle being outside the warranty and prior to the mileage being outside the warranty. The dealership has since given us an issue now that we are outside the warranty saying that any repairs now fall on us even though this is a recurring issue. They “attempted several repairs” to which none have fixed the problem. We have spent more time in a rental vehicle and switching back and forth to different vehicles waiting for the vehicle to repaired then any family should deal with a brand new vehicle. We are a family of 7 and in no way have time to be completely jerked around and in a manner that the dealership is now trying to wash their hands of. They essentially promised a resolve till we got outside of our warranty window and now it’s no longer their responsibility. We feel completely strung along as now they informed us we don’t qualify for lemon law even though we absolutely did. We were also informed by Janelle the service manager that our vehicle isn’t made for short trips. We have videos of the vehicle having these moments and we have everything documented through text with the manager and service manager of Honda Checkered Flag.
When I am stopped at a red light, the auto shutoff is activated, and when I lift off the brake and try to accelerate forward at the green light, the vehicle stalls for about 15 seconds, leaving the driver and passengers vulnerable to a car accident. One of the passenger seatbelts triggers the "no seatbelt" alarm, even when the passenger is buckled. If no one is seated there, there is no alarm. This only happens when someone is seated there. In order to bypass the alarm sound, the passenger has to unbuckle and re-buckle so that the car knows that the passenger is seated. Once the car shifts after a turn or curved road, the alarm will sound again. During an average 20 minute car ride, it'll probably do this 5-6 times, depending on how many turns or curves there are on the route.
Engine Idle Stop shuts off engine at stops but completely fails to restart when the brake is released. The vehicle stalls in traffic and requires a manual restart. This has happened four times from a stop, and once while driving on the highway.
