ENGINE, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
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.

ENGINE, UNKNOWN OR OTHER
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.

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.

ELECTRICAL SYSTEM, ENGINE
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.

ENGINE
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.

ELECTRICAL SYSTEM, ENGINE
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.

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.

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

Auto Idle Stop has malfunctioned several times causing me to get stuck at an intersection with warning lights flashing causing me to manually shift to “park” or shut down entirely to get it to restart. I was in the vehicle with my three kids and the light turned green and I could not move in heavy traffic. We took the vehicle into the Honda for service and they replaced my battery and did a full system check and battery reload test. Since replacing the battery, it has happened three times in 2 months. The remote start will not start when I try to get vehicle to start when outside the vehicle.

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

ENGINE, ELECTRICAL SYSTEM
This vehicle is a 1 year old (2025) Honda Odyssey with roughly 11,000 miles. On two separate occasions now, the auto start-stop feature has caused the engine to die altogether. On both occasions, the vehicle stopped at a red light in a busy intersection, the auto start-stop feature turned off the engine (intentionally), but when the light turned green and my foot came off the brake and onto the gas pedal, the vehicle died entirely. A number of lights and an error message illuminated on the dash board. From my online searches, it seems as though this is a very common issue. 1. What component or system failed or malfunctioned, and is it available for inspection upon request? Auto start-stop / engine. No not available. 2. How was your safety or the safety of others put at risk? Having your vehicle die at a busy intersection or stop sign is a huge risk. It can cause others to try and swerve around you, or it can cause someone not paying attention to rear end you. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle will be brought to the dealer in the coming days. Unfortunately this is my only vehicle and I cannot afford to lose it for an extended amount of time, therefore I have to prolong inspection and servicing. The issue has happened to me twice, and has happened to countless others online. According to others on the internet, the dealers are typically slow to address this issue, and even when "addressed" the issues seem to continue. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, see #3. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings prior to the engine cutting out altogether. Only a message after the failures. In both cases I do not remember what the messages said because I was scrambling to restart my car in a busy intersection.

ELECTRICAL SYSTEM, SERVICE BRAKES, STEERING
What happened? While driving my 2025 Honda Odyssey, the engine failed to restart during an Auto Idle Stop event at a 4-way stop/intersection. When releasing the brake to take my right-of-way, the engine stalled completely. The vehicle became immobilized, the power steering went heavy/stiff, and the brake pedal became difficult to depress. I had to manually cycle the ignition by shifting to "Park" and pressing the "Start" button multiple times to regain power while traffic was waiting. This has occurred twice. What component or system failed or malfunctioned? The Auto Idle Stop (AIS) system and the Starter/Charging System. A service technician recently documented a "slow crank" during routine maintenance, suggesting the battery is unable to handle the restart load. How was your safety or the safety of others put at risk? The vehicle stalled during a right-of-way transition (green light/4-way stop). This created an immediate risk. The loss of power steering and the stiffened brake pedal could have made the vehicle nearly impossible to maneuver manually on an incline during the failure. Has the problem been reproduced or confirmed? A dealership technician confirmed a "slow crank" symptom during a multi-point inspection, though they could not reproduce an issue. The battery tested good. Were there any warning lamps or symptoms before failure? Yes. A "slow crank" was noted by a technician when attempting to start my vehicle to check my vehicle mileage. During the stall itself, a red exclamation point warning appeared on the dashboard.

Vehicle stalled and shut down in traffic after the Auto Idle Stop function engaged at a red light turning the vehicle off and attempting to turn back on. All warning lights flashed. Vehicle would not turn on until after multiple attempts pressing ignition. This has happened multiple (3-4) times over a few months period. Honda dealership was unable to recreate incident but did identify difficulty with engine starting (i.e. slow crank) when manually turning on ignition; however, diagnostics found no issues.
