I currently own a 2024 Toyota Grand Highlander with the 2.4L turbo engine, which I purchased in July 2023. I have been experiencing a strong gasoline/fuel smell coming from the vehicle. I took the vehicle to Fox Toyota in El Paso for inspection. According to the dealership, the smell was caused by the gasoline I was using and they stated that the fuel contained too much ethanol. However, the gasoline smell was strong enough to be concerning, and I am not comfortable simply assuming that the fuel is the cause without further inspection. At this time, I have not been given a specific diagnosis identifying a failed component or confirming that a particular fuel-system component is malfunctioning. The vehicle is available for further inspection if requested. The strong gasoline odor raises a safety concern because the presence of fuel vapors could potentially indicate a fuel leak or another problem with the fuel system, creating a possible fire hazard. The problem was reported to and inspected by Fox Toyota in El Paso, but the dealership attributed the odor to the ethanol content of the fuel rather than identifying a defective component. I have not had the vehicle inspected by the manufacturer or any other independent facility at this time. I have not observed any warning lights or warning messages associated with the problem. The primary symptom has been the strong gasoline smell. The vehicle has the 2.4L turbo engine. I would like to know if other 2024 Grand Highlander 2.4L turbo owners have experienced the same issue and, if so, what the actual cause was and how it was resolved.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that while driving at an undisclosed speed, there was an abnormally strong gasoline odor inside the cabin of the vehicle. The contact believed that the odor was caused by a fuel leak. The vehicle was taken to a dealer, where it was diagnosed with an evaporator filter failure, and it was determined that a fuel leak was not the cause of the odor. The dealer stated that the vehicle did not require a repair and could still be driven with the odor inside the vehicle. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 45,000.

Ever since I got my car, sometimes it smells like gas on the right side of the vehicle. By driver side and right passenger side in the back. I assumed it was because I topped my gas off, but even when I stopped doing that, it still has a strong gas smell when the car is running and after turning it off. Not ever day, but ever so often.

After shutting engine off, there is a gasoline smell coming from the vehicle. This repeatedly happens. I took the vehicle to the dealer who did a variety of tests but could not diagnose or fix the cause. The result is I cannot safely park the vehicle in my garage. I have requested that the complaint be sent to Toyota on January 15. No response or acknowledgment as yet.

Since purchasing this vehicle when I have driven the vehicle and come home the vehicle smells of gas vapor/fumes. It's so bad the entire garage will fill with the vapor. Im afraid the garage will explode. I have to leave the vehicle parked outside for several hours until the smell is gone. This is a known issue for this car as others have complained about the same thing. Dealership has confirmed it is a known problem. They tried o tell me the first time I took it in that it was due to extreme heat in Las Vegas. I explained that our other vehicle and our friends vehicles don't do this and that is merely an excuse. After researching online I found that several other others in other states have the dame issue. When I recently took the vehicle in for software/radio issue as well as the gas vapor they did confirm it is a known issue. This is a safety issue as it could cause an explosion in small spaces where parked. We have an air conditioner for our garage but even at that it's extremely dangerous. This has happened on several occasions. Most recent is listed below.

I live in Arizona and the car has bad gas smell after drive a while(usually between 10-30 minutes) in a hot day (usually afternoon). I took the car to dealership and they replicated the issue and the dealership said Toyota told them it’s due to excessive heat and told us to use better quality gas which we are already getting gas from Chevron and Costco. Seems this is known problem because I saw other grand Highlander owners complained the same issue but Toyota is not doing anything to fix it. They can’t blame on the heat since they are selling the vehicles in AZ/NV. After drive the vehicle during a hot day, park the car in garage and the garage smells like gasoline.
