The idle stop system frequently fails to restart the car after shutting down the engine at a stop light. In some cases the car is difficult to restart using the starter button. In other instances the car restarts and then dangerously lurches forward.
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.
The vehicle completely stalled, we believe it’s related to the engine in reference to the idol on and off mechanism. We began to drive forward and the auto on off starter caused the car to completely shut down and freeze in an intersection.
I brought my van in for service because, when stopped at a traffic light, the vehicle enters automatic shutdown as designed; however, when I release the brake, the engine does not restart. Instead of restarting automatically, the vehicle remains off, and I have had to perform a hard start because it will not crank on its own. The van is a brand-new 2025 Honda that was purchased new. After inspection, I was informed that the battery would need to be replaced. During the same visit, I also reported a vibration issue. After checking this, I was told that the vehicle needs new shocks and that the tires show wear. I was further informed that the tires will not be covered. Given the age of the vehicle and the fact that it was purchased brand new, I am concerned about the need for a battery replacement, suspension repairs, and tire wear at this stage, as well as the decision not to cover the tires.
Idle stop failure. This has occurred many times. Presents itself failure to restart upon releasing the brake. Rough restart. Sometimes have to completely turn off car and restart.
Vehicle shuts down and will not restart. So far this has happened three times. After a long delay, took foot off gas, held brake and pushed start and would not start. On third attempt vehicle was very labored on start.
The idle stop feature sometimes fails to reengage / restart the engine. One time, the van failed to restart and the vehicle completely locked up while I was in an exit ramp to the freeway. I had to turn the van off and turn it back on to get it to shift into drive and go. Similar events have happened a number of times, since the summer of 2025. We have taken it to the dealer twice now, and have been told to "monitor" it. We found the NHTSA report #ea25004 and believe this is the issue we are experiencing. Occasionally, the idle stop will restart, but it's a very violent restart (car sputters and chokes in restart, sounds like it might stall). The car will make a warning light flash and give an error message, but it always clears too quickly to read it.
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.
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.
I am reporting a recurring issue with my 2025 Honda Odyssey, which exhibits difficulty starting the engine. Approximately two months after purchasing the vehicle in Dec 2024, the original battery failed and was replaced under warranty. However, the vehicle continues to experience problems when attempting to start. When I press the start button, the engine hesitates, cranks slowly, or feels as though it nearly fails to start. This issue occurs intermittently, regardless of weather conditions or the duration the vehicle has been parked. No warning lights or error messages have appeared on the dashboard the problem has occurred multiple times, most recently on Friday August 15th 2025, and creates a safety concern, as the vehicle’s unreliable starting could leave me stranded in potentially hazardous situations, such as remote locations or adverse weather. I have not yet had the vehicle inspected by a dealer for this specific issue, but I plan to schedule a service appointment to diagnose the problem. The prior battery replacement suggests potential issues with the electrical system, starter, or related components, possibly linked to the auto start/stop system currently under NHTSA investigation for 2018–2025 Honda Odyssey models. Additionally when driving down the road especially at low speeds the engine hesitates as if it’s not getting enough gasoline. Lastly the applecarplay screen and all other associated screens randomly go out. I have been to the dealership 3 times for repairs and they give me the run around saying they don’t notice anything so Honda won’t pay for anything and send me on my way.
The auto idle stop system on my 2025 Honda Odyssey fails to restart the engine when the brake pedal is released quickly after a full stop. When this occurs, the vehicle stalls completely in traffic and must be manually restarted by the driver. This has happened multiple times and is reproducible. The failed component is the auto idle stop/engine restart system. The vehicle is available for inspection. My safety and the safety of others has been put at risk multiple times because the vehicle stalled at traffic lights in active traffic, leaving me unable to accelerate through an intersection. The problem has been confirmed by Honda marysville dealership. The dealer stated they could not repair the issue and advised me to modify my driving behavior as a workaround. No repair was performed. The vehicle has been inspected by the selling dealership. A message appears during the failure telling me to restart the car. The problem first appeared within the first year of ownership on a brand new vehicle with basically zero miles at purchase. The cause appears to be a defect in the auto idle stop restart system that fails under specific braking conditions.
My 2025 Honda Odyssey has failed multiple times in the middle of the road when coming to a complete stop. Auto idle engages and when I try to press the gas the car malfunctions. I have to turn off the car and turn it back on again for it to start. Also at times the interior of the car will start to smell like gas.
