2024 TOYOTA HIGHLANDER Complaints

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.

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.

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!

The third row seat belts in the 2024 Highlander are very difficult to latch. I had to bring my Highlander to the dealership twice over the seatbelt buckles in the third row. The buckle part does not lift up high enough to grab the buckle to latch it. Anytime a child old enough to be in the third row sits back there an adult has to Buckle them because they can’t get the seat belt to latch to the buckle. It’s supposed to be a family friendly vehicle but if a 7 year old can’t buckle themselves, that is an extremely unsafe design. It often takes me 10-15 minutes to get kids buckled in my third row because of how challenging it is to get the seat belts to latch as an adult. I have had to use a butter knife to get them to latch. This safety issue , I did not have in my 2021Highlander. I don’t feel children are safe in the third row of my vehicle. This time the dealership said it had a debris in the buckle and that’s why it wouldn’t latch. However even when they do all latch they are very difficult to latch. These should be replaced with safe buckles that latch the first attempts

The trunk will not close using any of the buttons. This is an on going issue on so many newer highlanders.

The vehicle started stalling out randomly on the highway even with it being automatic, after getting home and parking it , it would not back up or drive . Took it to Toyota dealership and they said it’s an internal failure of the transmission which is a UA80 model , it only has 92,000 miles on it they can’t figure out what caused it . There are lawsuits with this vehicle already from other people and Toyota is not fixing the issue and won’t help with mine even after they have known what it is. I took it to one shop before Toyota to get a diagnostic it shown two codes one being in the transmission but they fixed that part and the vehicle still did not drive nor back up and then Toyota got the vehicle right after and they even said that it’s internal failure . Pictures listed below is how much for the tow truck fee, the part fee that I paid that was one code that was on the diagnostic tear down list , even after fixing payments and still not working and it going to Toyota and the messages from Toyota after everything got done and them saying the internal failure also . So not only 1 but 3 business that said internal failure .

I've been waiting for a recall repair based on a recall file nearly 8 months ago now. This recall still appears to have no remedy. I continue to get emails about this issue from my dealer, but when I call to schedule the appointment to fix it, they continue to tell me that no remedy is available yet.
