2025 Honda Odyssey

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.

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.

When Idle start/stop function is engaged and then goes to restart, the engine hesitates or fails to restart all together.

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.

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.

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 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.

2025 Honda Odyssey has been stalling due to Auto Idle Stop (AIS) failure to restart at traffic lights or stop signs. Engine fails to restart automatically and car needs to be manually restarted with push-button off/on switch. No apparent fix issued by Honda.

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.

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.

When stopped at a red light, the vehicle’s auto off system turned the engine off. When the light turned green and I removed my foot from the brake, the engine stalled and would not restart. I pushed the start button several times, put the vehicle in park, pushed the start button a few more times, and finally got it to restart. Luckily, this happened leaving my neighborhood and not in a more precarious situation. This has happened approximately 20 times now. I’ve had the vehicle inspected by the dealer. They could not replicate the issue, but acknowledged that Honda knows it is an issue. They aren’t willing to fix it until there is a recall on the vehicles. In the meantime, I have a one year old vehicle that sputters and struggles to restart more often than not. I have had the vehicle stall like this after the auto off system turned the engine off when trying to merge into traffic on the interstate. I had a near miss to an accident at that time because the vehicle stalled and would not restart.

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.

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.

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.

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.

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

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.

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,

After stop at traffic light with air conditioning on, the auto idle stop system engaged. When the brake was released, the engine stalled, able to be restarted after 5-10s. Problem exactly matches NHSTA investigation EA25004.

When stopped, my 2025 Honda Odyssey often fails to restart after the auto-idle stop engages. The engine stops, and fails to restart, and lights flash on the screen. I have to then turn the car all the way off, and on again, a process that can take upwards of 15 seconds. The issue happens daily. It will happen on the highway. Additionally, the button to disable the auto-idle engine stop is unreliable and sometimes doesnt work
