When Idle start/stop function is engaged and then goes to restart, the engine hesitates or fails to restart all together.
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.
The contact owns a 2025 Honda Odyssey. While the contact’s wife was stopped at a red light, the Auto START/STOP feature engaged, and the engine failed to automatically turn off as designed. The brake pedal was released, and the vehicle completely shut off. The vehicle was restarted, and the vehicle operated normally. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet contacted. The contact was informed of NHTSA Action Number: EA25004 (ENGINE AND ENGINE COOLING). The contact stated that the vehicle had experienced the failure listed in the investigation. The failure mileage was approximately 23,000.
My 2025 Honda Odyssey has had trouble turning on since it has been about 9 months old. It doesn't always turn on from being off. It doesn't always turn on when the vehicle is already on and the auto-start-stop system turns the engine off. More often than not it struggles to start but eventually does. I took it in for service and the dealership replaced the battery. It continued to not start. The new battery did not improve the symptoms. I scheduled another appointment for service and the dealership kept lying and gaslighting me into believing that they did something to improve the symptoms. They claimed to have updated the computer system software/firmware versions. I asked which ones were updated and they said that none were, it was all up to date. They claimed to have "reset" the auto-start-stop system. I asked how that would improve performance when the vehicle doesn't start from being off as well. The vehicle is unsafe to drive. It turns off at stop lights, stop signs, in medians when I am trying to make turns. The engine not restarting in parking lots from a complete stop is also very concerning. I hate and fear my Honda and I am scared to drive it. I have taken it to multiple dealerships to get it fixed and none will do anything. I have a video recorded after this occurred at a red light. The video shows the status of the vehicle and attempts to restart it. This was recorded February 19th 2026.
Over a period of the last several months when the auto idle stop engages at intersections (red lights, stop signs, etc) the vehicle will intermittently fail to restart. The vehicle stalls entirely and goes into a state where you are unable to restart the vehicle for anywhere from 30 seconds to several minutes. This is a very dangerous situation and each time have had other motorists honking and frustrated that the vehicle is not going when the light turns green. The vehicle is currently at the Honda dealership for the third time to attempt to repair this issue. The first time it was returned to me and I was told no issues found, the second time (after multiple more failures on road) was told the battery was faulty. The battery was replaced but the failures to restart continue. I can see that there are many claims of this same issue with Honda, however in our experience with this vehicle, very little has been done by Honda to solve this major safety issue.
The contact owns a 2025 Honda Odyssey. The contact stated that while driving approximately 40 MPH, the vehicle experienced a loss of automotive power. The failure was intermittent. No warning light was illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 12,000.
My 2025 Honda Odyssey features a standard Auto Idle Stop system designed to improve fuel efficiency by shutting off the engine when braking to a stop. While intended to restart upon releasing the brake, my 2025 models have reported issues with failing to restart or stalling.
My Odyssey has a no-restart issue related to Auto Idle Stop. Engineer did not restart at red light and I had to push the button twice. We were caught in traffic and was not safe.
The contact owns a 2025 Honda Odyssey. The contact stated that while stopped at a traffic light, the contact released the brake pedal and depressed the accelerator pedal; however, the vehicle failed to respond. The contact believed that the failure was related to the gas saving feature. The vehicle then stalled, but was able to be restarted. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 11,390.
When the Auto Idle Stop is engaged, I have now had 3 instances of the engine completely stalling when at a stop. Not only has the engine stalled, but I have difficulty getting the engine to restart. It has been very scary, as it has left me disabled at busy intersections while I struggle to get my van to start so I can move and pray nobody hits me while I sit there. I've even had to open the driver's door to get the van to restart. We've made a habit of manually turning the auto idle stop feature off every time we drive it. This problem has not occurred when the feature is turned off. The first incident of this was several months ago, and I already took it to my local dealer but they couldn't replicate the issue and did nothing about it.
I was stopped at a stop light and the idle stop function activated, turning off the engine, as designed. However, when the light turned green and I released the brake, the vehicle stalled out. I had to completely turn off the vehicle and restart it.
When the vehicle is stopped, and the auto-shut off engages, the vehicle will turn off, and the vehicle has to be restarted. Quite dangerous when in traffic and the vehicle is dead due to the auto-shut off not starting again. The fix is believed to be an updated starter engine computer and starter motor.
Auto start/stop functionality has resulted in vehicle stalling mid traffic as vehicle does not start and shutdowns. This has occurred in multiple occasions and most recently almost caused an accident with my family. We sent to dealer who checked battery and stated to issues. There were no warnings and dealer was unable to reproduce as they didn’t drive the vehicle. I have concerns with this new vehicle after finding other reports of this issue.
My car has been dying when I stop at stoplights. We took it into the dealership and they said the battery was sending error messages. So we replaced the battery. It is doing it again. Sometimes it starts but it is getting progressively harder to restart it. It is dangerous to be stalled at an intersection. The car is not even a year old.
The car stalled then stopped when I was at a traffic light, I had to press the start engine button multiple times to restart the car. This issue has occurred 3 times within the last two months.
Honda Odyssey EX-L sport 2025 has been facing the issue of idle stop not working causing engine to stall, engine failing to restart, shutting off completely during mid traffic especially during adaptive cruise control operation. This is causing an unsafe driving situation. While this issue was reported to Scott Clark Honda multiple times and they have claimed to fix this issue in Aug 2025, the issue continues to exist and root cause hasn't been fixed. This seems to be related towards the on-going investigation by NHTSA. Please help to resolve at the earliest since no further support is being received from Honda.
When I stop, they start stop, turns the engine off, but when I release the brake, the engine struggles to turn over and sometimes doesn’t and I have to put it in park to restart it. I have taken it to the dealership already once, but they said they weren’t able to reproduce it. I will be taking it back to the dealer to try again.
Idlestop fail to restart engine multiple occasions at busy intersections.
The idle engine feature is defective. Often, when stopped and the engine goes idle, it will not restart when the driver releases the brake. The van stalls, and the driver is forced to move the vehicle into park and start the engine again. This is dangerous and stressful because the driver behind you expects you to go, especially when the light turns green, but you are stalled, potentially leading to rear-end accidents.
Brand new vehicle and system shuts down a few times when in idle mode..(stoplight, stop sign) then I need to restart the car again.
