2025 Honda Odyssey fuel system problems

Filed Sep 5, 2026 · Electrical, Engine · VA

I am experiencing a serious and recurring safety issue involving the engine unexpectedly completely shutting off while the vehicle is being driven and separately, the engine intermittently failing to start after the vehicle has been parked. 1.The engine unexpectedly and spontaneously shuts off when the vehicle is stopped or slowing down, including at stop signs, traffic lights, and during traffic slowdowns. These events occur without warning or notice, and the vehicle does not reliably restart immediately. In nearly all instances, the engine has failed to restart for several minutes despite multiple attempts. This creates an extremely dangerous situation. When the engine shuts off unexpectedly in traffic, I am concerned that drivers behind me will not realize that my vehicle is experiencing a malfunction and may collide with my vehicle before I am able to restart it and safely move. These incidents cause me significant fear and stress each time they occur. I am not certain whether the vehicle’s Auto Start/Stop system is involved in these incidents or whether another component or system is malfunctioning. I am requesting that Honda and the dealership fully diagnose the cause rather than assuming that the behavior is normal operation of the Auto Start/Stop system. 2.Separately from the engine shutting off while driving, the vehicle also randomly and spontaneously fails to start after it has been parked. I have documented some of these incidents by video, including instances in which the engine failed to start. in which the engine failed to start despite multiple attempts. 3. As soon as these problems began, I took the vehicle to the service department of the dealership where I purchased it. At this point, the repeated engine shut-off and failure-to-restart conditions remain unresolved. I am requesting a thorough investigation and requesting that Honda identify the underlying cause of these failures and provide a permanent solution as soon as possible.

Engine failed to restart after turning off at idle at a stop. When releasing the brake the engine tried to turn on but stalled out. It is available for inspection upon request. No major safety concern, traffic behind the vehicle was prohibited from moving until the vehicle could be restarted. The failure has not been reproduced by a dealer or service center, or inspected by anyone else. There were no warning lights but after the failure a message displayed saying “To continue to drive, depress brake pedal and push switch”. The failure first appeared after 10,000 miles and occurred between 5-10 times since then.

My van will stall at red-lights. It started three weeks ago. The car is a year and a half old. The auto- idle stop system is activated. We stop at a red light. Car stops. When we go to start car dings and thankfully has started 3 times. This time, the car made a ding and did not re-start. I was stuck at a now green light and couldn't move. The dash flashed hit the brake to re-start. I did numerous times. I couldn't get the car to switch to park or drive. I tried switching the car on and off and couldn't get it restarted. I was disabled for about 2 minutes before it kicked back on. My kids were in the car and this scared me.

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 at a stop light on a major road, the vehicles auto start stop engaged. Upon the light turning green, I released the brake and vehicle failed to restart. The vehicle put itself into park and flashed a warning message "problem detected....." . I pressed the start button, and at first the vehicle failed to start, making a clicking sound, consistent with a dead battery or starter. I had to press the start button 4 times before the vehicle restarted and I could proceed. I was extremely concerned as I had my wife and three kids in the car, unable to move forward on a major roadway. I have an appointment at the dealer for this Friday.

My vehicle has experienced repeated unexpected engine shutdown/no-start events, creating a significant safety hazard. The engine has unexpectedly shut off or failed to restart while stopped in traffic and while entering traffic, resulting in a sudden loss of propulsion. On one occasion, the vehicle would not restart for approximately one minute. The vehicle was inspected by an authorized Honda dealership, and the starter was replaced under warranty in July 2025. The repair did not correct the problem. Since that repair, the same failure has occurred multiple additional times. The issue has now occurred at least six times over approximately one year. Because the condition is intermittent, the dealership has not permanently identified the root cause. The vehicle is currently being returned to the dealership for further diagnosis, and I have requested that the matter be escalated to Honda Technical Assistance (Tech Line) and Honda Engineering. This defect creates a serious safety concern because the vehicle can unexpectedly lose power while in or entering traffic, increasing the risk of a collision. There were no consistent warning lights or messages before the failures, and the condition occurs intermittently without warning. The vehicle remains available for inspection.

Power loss when idle; it fails to restart normally, and then the car stalls for several minutes. It happens frequently despite the van being less than 2 years old (at least 3x weekly)

Our 2025 Honda Odyssey has now experienced three failures for the same defect, including two starter replacements within two weeks, without resolution. The most recent repair, overseen by Honda Tech Line, happened after the vehicle died June 2 while in traffic and it had to be towed to the local dealership using our insurance. On June 15 the vehicle died again, just five days after I picked it up with assurance that this issue was resolved, and it is was towed back to the dealership by Honda Towing. The repeated part swaps, without root‑cause diagnosis, clearly have not resolved the issue and have left us with a one‑year‑old vehicle that is unreliable and unsafe to operate. My minivan has failed in the middle lane of a major road while idling at a stoplight twice and in a parking lot once. All incidents were within 15 minutes of driving and 5 miles from my home. This is a critical safety defect and the repeated failures place this vehicle within the criteria that may qualify under Kentucky’s lemon law. We have not made that claim yet, but we are formally documenting the repair history and escalation. ———- -Starter failed and was replaced twice. This could have something to do with the auto start/idle system. -our one year old van is unsafe and unreliable. It died near a major intersection while idling at a stop light. I was in the middle lane and it wouldn’t restart for 5 minutes. I was very afraid my children and I would be rear ended. -the dealership has confirmed the problem, but they not been able to recreate the scenario despite it happening on 3 separate occasions. -Honda Tech Line has been directing the local dealer what to do after the first starter replacement failed. I filed a claim with American Honda. -no warning lights/lamps prior to failures

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.
