2025 Honda Odyssey other reported problems

UNKNOWN OR OTHER

5 times since July 2026 the vehicle 2025 Honda Odyssey fills with the smell of gas. The smell fills the entire garage. After the 4th incident, it was brought to the dealership on 8/18/2026, however they were unable to reproduce the issue smell. They stated the EVAP system was function and at the time there were no obvious leaks. Despite it being a known issue, there are no recall or repairs per the dealership. They stated that Honda is apparently aware and are "investigating." The smell recurred today and was immediately brought to the dealership since the problems was not reproduced when previously in their possession. It was noted by multiple staff member but since there is no known fix, there was nothing the dealership could do. They are aware of several other Honda Odysseys with this issue in the same area. I was instructed not to park the vehicle in the garage which makes me concerned for mine and my family's safety. The smell can be very overwhelming and makes me lightheaded.

While driving our 2025 Honda Odyssey, my wife came to a complete stop at a red traffic light. The vehicle’s Auto Idle Stop feature was enabled, as it is by default each time the vehicle is started. When the light turned green and she attempted to accelerate, the vehicle would not move. The engine appeared to be running/revving when she pressed the accelerator, but the vehicle remained stationary as though the brake was still engaged. A message appeared on the instrument panel instructing her to depress the brake pedal and press the start/stop button. Initially, we believed the electronic parking brake might have been engaged, so she attempted to disengage it, but this did not resolve the problem. She was stuck in an active traffic lane at an intersection and unable to move the vehicle, creating a significant safety concern. Another person advised her to completely turn the vehicle off, wait approximately 10 seconds, and restart it. After doing so, the vehicle operated normally again. After this incident, I learned that NHTSA is already investigating Auto Idle Stop/no-restart complaints involving Honda vehicles, including 2025 Honda Odysseys, under Engineering Analysis EA25-004. I also learned that Honda has previously communicated with dealers regarding Auto Idle Stop no-restart incidents involving 2023–2025 Odysseys. This was an extremely concerning failure because the vehicle unexpectedly became immobilized at a traffic light and could not be driven until it was shut down and restarted. I am concerned that this could happen again in a much more dangerous situation. I am submitting this complaint so that this incident is documented as part of NHTSA’s investigation and to request that NHTSA determine whether a safety recall or other corrective action is necessary.

While waiting at a stop light, the engine turned off and the vehicle forced itself into park. Taking my foot off the brake, had no effect. I was not able to put the vehicle back into drive. I had to shut off the engine and restart it in order to drive again. Of note, the AC and carplay were running at the time of the engine failure. No warning lights appeared. Cars behind me were honking at me. I have an appointment scheduled with the dealership to assess the auto-idle function.

Starter issue both during idle start/stop mode and going from off to on. Owned for about 20mos and happened first maybe 6mos ago and has happened a dozen times since then. So dangerous! We have had idle start freeze at a green light and are worried we’ll get hit. Sister in law has the same problem with hers. This needs to be fixed immediately!

I was at the red light and the car wouldn't come out of idle. The battery light came on and the i tried to turn the car off and it just keeps cycling. I had to open the door for the car to cut off and then restart the car. This is the 3rd time this has happened and almost resulted in me and my children being hit.

I was stopped at a stop sign and my 2025 Honda Odyssey shut off. I stopped the AIS engaged, then when I took my foot off the brake the engine didn't engage. The car wouldn't move. I took me about 30 seconds to get the mini van's engine to engage. This is the second time this type of incident has happened.

I have now had three instances within the last three months where my car has stalled out at traffic lights when the Idle Stop was engaged. The first two times, the car stalled out when I pressed the shut off switch for the Idle Stop on the center console. I am not sure about the first time since I was surprised the car stalled. The second time it happened, I hit the button twice in immediate succession and then the car stalled. The third instance was this past Thursday, 8/6/26. I did a double tap on the brake pedal when the traffic light turned green and the car stalled out. The safety of myself and my children in the car with me has been put at risk since each time it happed we were stopped at a red light at a major intersection on busy major roads. Cars were coming up fast behind us and could have rear ended either myself or the cars behind me (when there were cars behind) pushing them into my car and injuring all drivers and passengers involved. Today, I took the van into the dealership where I bought it for their service department to investigate. The VIN on the van is not covered under TSB 23-027 but I did not ask them yet whether is is covered underJuly 31, 2025 nationwide dealer bulletin ("Request for Visit: 2023–2025 Odyssey/Passport/Ridgeline Auto Idle Stop No Restart") which explicitly covers 2023–2025 Odyssey with no VIN-range cutoff, based on manufacture date after 11/2022. There were no warning lamps, messages or other symptoms of the problem prior to the failure each time.

2025 Honda Odyssey with 21.5k miles on it. Pulled up to a stoplight after a 3 hour drive. Auto stop turned the van off. When the light turned green the van failed to restart. Put the vehicle in park, turned it off, waited a few seconds and attempted to re-start it. Van restarted but very sluggish, like the battery was dead. Pulled in and parked. Van started normal the rest of the day. Took it to the dealer 2 days later. They noted the battery was a little low but no codes and no explanation for why it failed to restart. They checked alternator and starter and claim they are both good.

Idle stop system failed at red light. Rather than restarting when light turned green, car turned off and required being turned off and back on in order to restart.

NHTSA complaint #11754416 — an unverified report by a vehicle owner.

UNKNOWN OR OTHER

When the vehicle comes to an idle stop and brake is released, the vehicle shuts off and does not kick back on. Only solution in the moment to get the engine to restart is trying to start the car repeatedly until it comes back on. Vehicle has been looked at for this issue but they were unable to replicate the issue. Engine light will sometimes come on when this occurs. Other times the charging system light comes on, as well having multiple warning lights coming on at once. Causes a safety issue when it’s not restarting while in traffic. Issues started a few months after purchase. Took it into the dealer and they determined the throttle body needed to be replaced.

I have experienced numerous instances where my car will stall at a stop light and then fail to restart, even with switching gears to park before resuming to drive.. I have had to turn on and off the engine multiple times at a si hole stoplight before the car would resume movement. This scenario has now happened at least 3 times. I am a mom driving a minivan of kids and this is concerning for our safety. These are not long stop lights. Sometimes even at a stop light I feel a strange pulling sensation.

UNKNOWN OR OTHER

The van is experiencing the auto stop-start defect causing major safety issues for my family. The car stalls randomly at stop signs and stoplights and is unable to be restarted quickly, creating a major traffic and safety hazard. The car often will not turn on at start up. The dealer stated that it needed a new starter. Then said that Honda would not replace the starter until a tech looked at it. Then after several weeks still had not moved forward getting a tech. Then said to bring the van in for them to keep until they could get a tech, and offered a small car without room for the kids as a loaner for the indefinite amount of time they want to keep the van. There were no warning lights when it has happened. This issue is already being investigate by the NHTSA - Investigation Number EA25004. This is a known issue for Honda and I am unable to get a safe vehicle or get my vehicle fixed. Below, i have to choose a date for the incident, but this is ongoing and has happened on more dates that I can possibly log. It happens weekly, if not daily.

Auto idle system shuts down and stalled vehicle on intersections twice. Had battery replaced. Continued. Replaced starter (around 15,000 miles) Now at 34,000 miles it is starting to do it all over again. Stalled at intersection, battery sluggish. I turn off the auto idle system as soon as I start the car, but cannot remember to do so every time. Extreme safety issue where I live in major stop and go traffic with multiple children in my vehicle at all times. They are currently checking battery and starter again. No codes ever came on to indicate issues. Vehicle just stopped when auto idle engaged.

UNKNOWN OR OTHER

The two most recent incidents occurred on XXX. 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. Honda case number: XXX VIN: [XXX] Vehicle: 2025 Honda Odyssey Approximate mileage at most recent incident: 15000 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.

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.

Waiting at traffic light to turn left onto Dixie Hwy from Kyles Lane in Ft. Wright, KY. After taking foot off brake, car went into park by itself. Unable to put into drive or put on hazard lights. After calling 911, turned car off, then it restarted. Cars behind were honking. Thankfully an accident did not occur. Will take to Honda dealer on July 20, 2026 to check it out

NHTSA complaint #11751333 — an unverified report by a vehicle owner.

UNKNOWN OR OTHER

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.

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.

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 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.

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.
