2025 Honda Odyssey Fuel System Problems

Owner reports

Selected complaints filed with NHTSA by 2025 Honda Odyssey owners, lightly cleaned up (personal details are redacted by NHTSA).

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 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. …

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 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. …

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.

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 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.

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.

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.

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.
