1 Other Fuel System problem

Failure Date: 08/26/2026

Driving the vehicle a strong smell of fuel vapor is noticeable coming from rear driver side of vehicle by rear door and fuel cap area. This happens when car is driven for long periods of time or on hot days. I drive my car daily and it happens every day. Smell gets so bad it gets in to the cabin area. Causing me to get headaches or light headed feeling making it unsafe to drive. I have taken vehicle to the dealership but nothing was done. The only thing they said they could do is clean and disinfect my ac vents. This issue has been on going since I bought the vehicle brand new 0 miles when I purchased it. There are no warning lamps or messages that appear when the issue starts. After returning home I have to park my car out side for a few hours until the fuel smell goes away and it is safe to park in my garage. I have talked to other people who own the 2024 Highlander and they have stated they to have experienced the same issue also taking it back to the dealership but no fix for the issue. Please have Toyota find a fix for this issue it is a huge safety concern for the people and the environment for the amount of fuel vapors that this car releases.

2 Other Fuel System problem

Failure Date: 08/01/2026

There is a strong odor of gasoline coming from the car, to the point where the fumes are so strong they’re entering our home and making it very unsafe. We brought the vehicle to the Toyota dealership, and they said they couldn’t do anything about it. Keep in mind the car is still under warranty. Upon doing further research from reddit, this seems to be a common issue with 2023+ Highlander and grand Highlander models; however, Toyota is refusing to correct these issues. This is a hazard to say the least and something needs to be done ASAP!.

3 Other Fuel System problem

Failure Date: 08/01/2026

I have been experiencing a gas smell issue with my Toyota Highlander near the rear of the car by gas cap area upon putting in gas and driving. The smell starts typically when it’s a hot day outside and I only usually get half a tank worth of gas. After getting gas and driving about 15-30 mins. Is when the smell of gas starts. I recently took my car it to the local Toyota dealership and they checked the purge valve, fuel canister and evap system. The technician did state that the fuel rail failed slightly. But overall, they stated there no codes after testing and the technician did state he smelled the gas faintly. But that since there are no codes to pinpoint an issue they cannot fix or figure out the issue. Please figure out this issue, as this is a real concern to have this issue and drive this car with myself and family in it.

4 Other Fuel System problem

Failure Date: 02/09/2026

Vehicle smells like fuel after engine toggles on and off between the hybrid system. This issue is intermittent, but when it is taken to the dealership they smell the fuel, with no luck duplicating the issue. I have also noticed when the smell is present the vehicle seems to run rough.

5 Other Fuel System problem

Failure Date: 04/11/2025

Strong smell of fuel after a hot day. This is a new vehicle purchased new on 2024. No warning lights on dashboard. After reading a few threads about the same situation on newer Highlanders it seems like it's being ignored.
