2024 Toyota Highlander owner complaints

When the AC system is turned on, the idle increases from 740rpm to 760rpm. It engages the torque converter in the automatic transmission causing the car to move forward on its own. This makes it difficult, whether you are in traffic or at a stop light where there are vehicles stopped infront of you. The driver has to press hard on the brake pedal to keep it from moving forward. The local Toyota dealership (Hendrick service manager and two service technicians) said it was fine. Toyota Brand Engagement sent Eric who is their corporate regional engineer to inspect the car. He said it was fine. I have spoke with Toyota Brand Engagement several times and at various levels who all say it functions fine as the idle is within limits. I asked Toyota for an idle specification sheet but

I purchased a brand new 2024 Toyota Highlander Limited on [XXX]. On September 12th, we were going on our first road trip with our [XXX] son to Wilmington, NC (~209 miles from where we live). I bought this car as it was bigger and with a newborn wanted to feel safe. Approximately 15 miles out, as I was gassing the car on the highway, the speed limit was slowly dropping. After I released the gas, there was a slight jolt and then I was able to safely pull over on the side of the highway. To say I felt unsafe with cars flying by going 70 mph and the car slowing down out of my control with a newborn in the car is an understatement. With less than 300 miles on the car, Toyota of Wilmington confirmed it was a faulty transmission. In addition to the poor quality and safety concern, customer servic

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 dri

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!

I was driving on the highway when I heard a very loud bang. I felt like the car had been hit by something and immediately looked for a large truck around me. With such a loud noise I figured something that loud had to be kicked up by something large. No trucks were around me of any size. Just a few cars. I looked at all my windows to see if I had a crack. Nothing. I assumed whatever hit me must have hit the car and not glass. Once I pulled over I walked the perimeter of the car and found nothing. With how loud it was I knew something must have happened. I assumed maybe it hit underneath and turned my car back on to see if any malfunction lights came on. All was good so I continued to drive. I could hear a wind noise like a window was open but no windows were. A loud air sounding noise with

I was in the drive thru at a fast food restaurant and after I placed my order I was about 5 cars from the pay window. As I went forward where there was a curve I stopped and then when the car in front of me moved forward to the pay window I let up on the brake and accelated slowly. When I put my foot on the brake pedal it went to the floor and the car would not stop. I served to the right of the car in front of me ( I did not hit it) and rolled to the parking space to the right. The car hit the curb and bounced up a little and hit the sign and then rolled backwards and I swerved the car so as to not hit the cars in line. I tried to put the car in drive but it wouldn't go. I then put the car into park which stopped the car with a jerk. After a few minutes I turned the car off as the br

The contact owns a 2024 Toyota Highlander. The contact stated that while driving at unknown speeds, the instrument cluster was blinking. The contact expressed that she was concerned that the vehicle was unsafe to drive. The contact received the recall notices of NHTSA Campaign Numbers: 25V744000 (Back Over Prevention) and 25V595000 (Electrical System); however, the part to do the recall repair of NHTSA Campaign Number: 25V595000 (Electrical System) was not yet available. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and filed a claim. The failure mileage was approximately 13,357.

On or about Oct, 3rd, 2025 , my vehicle experienced the 'Check Engine' light and all the warning lights lit up, the hybrid system failed to engage, the vehicle would say “park somewhere safe /take to dealer” . I immediately took the vehicle to the authorized Toyota dealership, Wonderies Toyota Alhambra , for diagnosis. They said they could not find anything, reset the sensors, and told us to come back if the problem persisted, and one hour later the system lights lit up again. We returned the same day and the dealership informed me that the issue is a severe corrosion of the underbody wiring harness , specifically citing external damage or 'spillage' as the cause. The estimated cost for a complete replacement of the wiring harness is approximately $6- 7,000.00. I contend that this corr

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

Ours has pulsing brakes and brakes feeling "off" at low speeds, potentially due to the interaction of regenerative and conventional braking. The brake pedal will also suddenly jolt the car forward when switching between braking systems. The system is unsafe.

There are many times over the course of the past few months where I am braking and the car lurches forward at least a few inches before coming to a complete stop. It feels as if it is being rear ended at a slow rate of speed. I have not been able to identify any pattern in this problem. It happens when I am braking to slow down at a faster rate of speed or when I need to come to a complete stop at a stop light or sign. This is very dangerous as I fear that one day when I need to brake I will not be able to and will hit something as the car keeps moving several inches after braking sometimes. I have brought the car to the service department at the dealership and they have told me that it is normal and there is nothing that they can do about it as they were unable to replicate it. However, t

Brakes "let go" for a second or so when using. I have noticed this when coming to a stop sign at low speeds and especially if road surface is uneven. It does not happen all the time but it is very scary to suddenly lose the brakes! This puts others at risk because the car briefly speeds up when the brakes let go. It has happened at least twenty times while driving this SUV, most recently today. Please issue a recall for this!

UNKNOWN - 2024 Toyota Highlander makes a drumming or hooting sound when driving over normal to slightly rough roads. It is not related to expansion joints in the road. 1st dealer said it was a rt. wheel bearing, changed it and it did not work. He then said it was in all Toyota's with 20" wheels. I paid to change tires and wheel to no avail. 2nd dealer said it was normal even though mechanic heard the noise. His supervisor said it was fine and they would do nothing to try to isolate the noise. Noise is very obvious.

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

My driver side rear door handle comes off when I open the door. I am having the dealership look into this on 8/28/2025.

While slowing down, the vehicle will suddenly lunge forward, as if It hit a patch of ice and then slow again. This started happening around 30,000 miles. The dealer said this is because of a transition between hydraulic braking and regenerative braking and is "NORMAL". This did not start until 30k miles. I have owned 4 hybrid vehicles and only this one does this. Upon reading and studying online, there was a bulletin for an earlier generation of this type of problem. Clearly, it is an issue as I am not the only one with this problem.

The contact owns a 2024 Toyota Highlander. The contact stated there was an abnormal fuel odor inside the vehicle's cabin coming from the rear of the vehicle near the fuel tank. No warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the vent valve remained open causing fuel to leak from the fuel tank and as a result the fuel cap needed to be replaced. The vehicle was repaired however the failure persisted. The failure was intermittent. The contact stated that the odor was extremely strong, causing the driver to sustain headaches. The fire department issued a letter with a statement that there was a fume odor coming from the vehicle. The vehicle was taken to a different unknown dealer however, the dealer was unable to determine the cause of the failure.

when I attempt to accelerate from a stop, or slowly rolling, there is a 2-3 second delay, sometimes longer, prior to the vehicle moving forward. during the delay, when accelerator is pressed, the engine does not rev, nothing happens at all. it's scary. the highlander has less than 9k miles on it. this has been happening more and more frequently. I have contacted toyota, they have yet to provide a response or solution for this safety issue.

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 fe
