There’s been several incidences but the most recent one was today. While idling, my car fills up with a gas/exhaust smell. It happens intermittently but it has happened 4 times in the last week. If I shut the recirculate mode off, the smell will start to go away till I turn the recirculate back on. After further investigation, there’s several people with this issue as Honda odyssey owners. Problem has been reproduced several times on my own, however I will be taking to a dealership next week.

There is a very strong exhaust smell in the cabin. This occurs under the flow and recirculate HVAC options and is not improved by changing the engine and cabin air filters.

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.

2026 Honda Odyssey: Strong Exhaust/Fuel Odor in Cabin Causing Dizziness and Nausea I am submitting this complaint to report a potential safety issue involving a vehicle that is less than one year old. Beginning this past weekend, the vehicle suddenly began filling the passenger cabin with a strong exhaust-like odor during normal operation. The odor is severe enough that multiple occupants have experienced symptoms such as dizziness and nausea after spending approximately 10 minutes inside the vehicle. I visited my local Honda dealership to report the issue and seek assistance. According to the representatives I spoke with, Honda believes this is a known and widespread issue affecting multiple makes and models and that it is allegedly related to recent changes in gasoline formulation. I was further informed that Honda is aware of the issue, that engineering teams are working on a solution, and that there is currently no corrective action available to consumers. Honda also stated that, despite the odor, the condition does not involve toxic fumes and is only an odor concern. I am not ready to accept that explanation without further investigation. At this time: The condition began suddenly and without warning. The odor is strong and persistent. Occupants have experienced dizziness and nausea while riding in the vehicle. Honda has not identified a repair or mitigation. Honda has indicated that this may be a broader issue rather than an isolated vehicle defect. I am requesting that the federal safety agency review this matter to determine whether similar complaints have been reported and whether this condition warrants further investigation as a potential safety defect. I have also requested that Honda provide written documentation supporting its statements regarding: The alleged fuel-formulation cause of the issue. The assertion that occupants are not being exposed to harmful fumes. Any technical bulletins, engineering analyses, or communications related to this condition.

The vehicle's auto idle stop system is malfunctioning, resulting in the engine failing to restart from a complete stop. This total failure has occurred on five separate occasions, including while stopped in active traffic intersections. Prior to these total restart failures, the vehicle showed the following symptoms: 1) Initially, the vehicle experienced rough engine idling, abnormal vibrations, and a raw gasoline odor after driving. 2) This progressed to a noticeable delay between releasing the brake pedal and the engine attempting to ignite, during which the starter sometimes sounded strained. 3) This has culminated in the current defect where the engine shuts off normally when stopped at an intersection, but completely fails to immediately restart when the brake is released. This defect completely immobilizes the vehicle in active traffic lanes, exposing us to an immediate and severe risk of a rear-end collision. When the engine fails to restart, the vehicle locks the transmission out of drive and triggers a warning on the dashboard. It is a highly hazardous situation, especially with a lot of distracted drivers on the roadways.

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.

The Honda High Pressure Fuel Pump Recall is an ongoing and critical safety campaign impacting numerous Honda and Acura models primarily from the 2017-2022 model years. The defective fuel pump component can fail unexpectedly, causing sudden loss of engine power while driving, significantly increasing the risk of a crash or fire. I am the manager and co-owner in an automotive mechanic workshop in Miami, and in the last year several Honda Odyssey have arrived at my workshop with this problem with the high-pressure fuel pump. All of these cars were manufactured in 2022 and 2023. Symptoms begin after accumulating more than 80,000 miles traveled. The main symptoms are: Problems and delay when starting, loss of power, vibration, noise and tapping of the fuel lines at the inlet of the engine. This vibration and noise are felt much louder from inside the cabin, because the fuel lines are attached to the fire wall of the engine compartment. High fuel consumption, reducing the autonomy of the vehicle up to about 12 to 14 miles per gallon, when the Odyssey has a proven autonomy between 19 and 21 miles per gallon under normal conditions. Strong smell of fuel. The vibration increases by increasing the revolutions per minute of the engine, causing the connections of the fuel lines to suffer deterioration, cracking and loss of pressure, causing fuel leaks that could be the main cause of fire of the engine and the vehicle, in turn putting the life of the driver and his occupants at risk. For a few weeks I wanted to submit this request for extension of Recall to Honda for the Odyssey models of the years 2022 and 2023 through the federal safety agency. But it was not until today that I decided to do it because I also own a 2022 Honda Odyssey EX-L with more than 90,000 accumulated miles, just 2 weeks ago my vehicle began to present all these symptoms mentioned above.
