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 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
My car was parked in the driveway with the engine running. The engine was then turned off from outside the vehicle using the start/stop button. Once the engine stopped, the car moved backward down the sloped driveway and struck a pickup truck that was parallel parked on the street. I then entered the vehicle and attempted to shift into drive, but a warning appeared indicating the hybrid system was off and instructing me to put the car in park. Multiple attempts were made to drive the car forward, but instead, it was driving in reverse. The car would not move forward for approximately five minutes. I eventually turned the engine off and restarted it after a couple of minutes. After restarting, I was able to drive the car off the street.
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.
The contact owns a 2024 Toyota Highlander. The contact stated that while placing groceries in the trunk, the lift gate violently fell on her head. While in the trunk, the liftgate came down, and her cousin was able to stop the liftgate from closing on the contact. There were no warning lights illuminated. The contact had a continuous headache and dizziness, and it was determined that she had a concussion when medical attention was provided at the emergency room. The vehicle was taken to a local dealer, who was unable to duplicate the failure, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and referred her to the NHTSA hotline. The failure mileage was unknown.
brakes 4 complaints shown
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!
Brakes do not engage sometimes until brake is almost to floor. This has happened to the 3 people who have driven it and almost caused an accident. In fact the warning flashes on dashboard. Brakes have almost failed and yes, it is available upon request. Our safety was at risk because all 3 of us almost hit the person in front of us. The problem has not been reproduced by the 2 service places I went. Neither of them drove it. The first Toyota service center checked the OBD2 scanner and it showed no problems. The second place did not check anything and said they would when I come back for my 15,000 oil change. The brakes were inspected by the first service center but they did not drive it. I bought the Highlander Hybrid brand new and it started immediately. I traded in the exact same v

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

powertrain 2 complaints shown
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 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 mu

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.

fuel system 1 complaint shown
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.
cruise control 1 complaint shown
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.
