2024 TOYOTA HIGHLANDER Safety Overview

Component: ENGINE,FUEL/PROPULSION SYSTEM

"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."

"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."

Component: FUEL/PROPULSION SYSTEM

"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!"

Component: SEATS

"The contact owns a 2024 Toyota Highlander. The contact received notification of NHTSA Campaign Number: 26V128000 (Seats); however, the part to do the recall repair was not yet available. The contact stated that while lowering the 2nd-row seat, the seats failed to remain locked in place as intended. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 10,000."

Component: SEAT BELTS

"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"

"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."

Component: Other/I am not sure

"I am submitting a formal complaint regarding a safety defect in my Evenflo Revolve 360 car seat. The white foam headrest component has completely detached due to what appears to be a failure in the original adhesive. This issue occurred despite proper use and adherence to all manufacturer guidelines. This component is part of the headrest system and plays a role in impact protection. Its detachment raises serious concerns about the structural integrity and crash performance of the seat. As a result, I no longer feel it is safe to transport my child in this car seat. I want to be clear that I am not comfortable attempting any at-home repair, including gluing the foam back into place, as modifications may compromise the seat’s compliance with federal safety standards and manufacturer specifications."

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

"Second row seats not latching when moved forward. Sliced up multiple finger when trying determine what was causing it not to latch. Put in a couple of stitches in 2 finger and bandage up the remaining 2 fingers"

Component: TIRES

"The tires have not “failed,” but they are dry rotting on both the sidewalls and inside the tread. These came as the OE tires, size is 235/65 R18. This is a daily driven car with almost 30,000 miles on the odometer. There is no reason the tires should be dry rotting. This is a severe safety hazard, as most tire shops wouldn’t mount, balance, or even touch these tires if they were dry rotted this quickly. The tires have been rotated every 10,000 miles or so, and have been kept properly inflated throughout their life. They were made on the 42nd week of 2023. They began showing symptoms of light dry rotting around 6 months ago, but the problem has finally spread to the sidewall."

"When I purchased the vehicle I was told I could use Apple CarPlay, or Toyota's Drive Connect. Apple works better so I've always used that. I am used to having to clear Toyota's pop up ads for Drive Connect several times per week, even once per day. Recently Toyota's Drive Connect ads pops up on screen every few minutes regardless of what hands free app I'm trying to use (navigation, phone call, audiobook, etc.). It's distracting which is dangerous and keeps me from being able to use the hands free feature through Apple Car Play in my car. After calling Toyota corporate and Toyota brand engagement, both entities told me the only way to get the pop up ads to stop is to subscribe. The pop ups are dangerous and not what I agreed to when buying the car, so it feels like blackmail to be told it will only stop if I pay them $15 per month for a subscription to something that I won't use that was not a required feature when I purchased the vehicle."

Component: ENGINE,FUEL/PROPULSION SYSTEM

"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."

Component: POWER TRAIN,ENGINE

"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 ."

"Safety Recall remedy not fixed in a timely manner"

Component: POWER TRAIN

"Detailed Description of the Incident: I am reporting a recurring powertrain safety issue regarding the 8-speed automatic transmission (UA80-series) in my vehicle. [Symptoms] During cold-start conditions (outside temperatures below 30°F), the vehicle consistently experiences a violent jerk/shock and an audible clicking noise during the first 2nd-to-3rd gear transition. This physical impact is severe enough to be felt directly by the driver through the accelerator pedal. The issue is highly predictable, occurring once after every "Cold Soak" period (6+ hours of sitting). [Dealership Failure] I presented the vehicle to an authorized Toyota dealership for diagnosis. Although the conditions for the issue were met, the technician stated they "could not feel or verify" the shock that I, as the primary driver, clearly experience. By failing to acknowledge a physical powertrain shock, the dealership is dismissing a potential mechanical failure as "normal operation" simply because no Diagnostic Trouble Codes (DTCs) are triggered. [Safety Risk] The failure to verify this symptom does not eliminate the safety risk. This unexpected shift shock causes a momentary hesitation in power delivery. If this occurs while merging into traffic or navigating an intersection immediately after a cold start, it creates an unpredictable vehicle response, significantly increasing the risk of a rear-end collision. [Request] I request NHTSA to investigate this specific 2-3 shift shock in 2023-2024 Toyota Highlanders. Toyota’s reliance on electronic codes to diagnose physical transmission defects is leaving drivers at risk of sudden powertrain failure or accidents in cold climates."

Component: SERVICE BRAKES

"BRAKING SYSTEM WHEN APPLYING BRAKES, ESPECIALLY WHEN APPLYING DOWNHILL, TEMPORARILY RELEASES AND ACTS AS THOUGH BRAKES ARE NOT APPLIED ANY LONGER FOR A BRIEF PERIOD OF A FEW SECONDS THEN REAPPLIES. IT DOES SO THAT IT IS VERY OBVIOUS WITHIN THE CAR. THERE IS A KNOWN ISSUE WITH THE TOYOTA HIGHLANDER HYBRID BRAKING SYSTEM AND IT SEEMS THAT IT HAS NOT BEEN RESOLVED IN NEWER MODELS. ASKING NTHSA TO ADDRESS WITH TOYOTA AND GET IT FIXED.Technical Service Bulletin for 2020-2022 Toyota Highlander Hybrid Braking Issue. Some drivers reported a momentary transition from regenerative braking to hydraulic braking, particularly when driving downhill or turning with light brake pedal application. Toyota has provided a software update for the brake actuator control module to improve brake feel."
