2024 Toyota Highlander Owner Complaints

Driving the interstate at 75 mph, my sunroof spontaneously shattered covering us with shards of glass. Toyota dealership and insurance said a rock must have hit but there were no other vehicles near us. Was not covered under warranty, so insurance adjuster approved new sunroof install and repaint roof for over $3,000. The loud explosion and subsequent broken glass could have caused major accident as well as blindness. We feel an investigation into glass quality should be done. In my opinion, vehicles shouldn’t even have sunroofs.

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 brakes had not come back. I sat in the driveway blocking it. As I sat there I checked the screen for any error messages or warnings and saw none. After about 10 or 15 minutes I tried the pedal again and got pressure. I was able to start the car and pulled it into the parking spot. I then called Totota roadside service and had the car towed to my house. Today as instructed by Toyota service they sent a tow truck to my house to tow it to the dealership service department. The service manager checked something and said nothing showed up but would have the tech check everything out.

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.

My car has integrated CarPlay installed for mapping. When used wirelessly with all mapping services (Apple Maps, Waze, Goole Maps) my car will appear in fields, the wrong streets, in houses. I will be given directions to turn on streets that are not where I physically am. First I worked with Apple Customer Care for over 15 hours. They have determined it is not an Apple issue. They believe it is an issue with the GNSS module in the car. I took the car twice to the dealerships service departments. The first service department did not duplicate this issue. They told me I had to plug the phone in to not have the problem. My vehicle is bluetooth, it works wirelessly! The second dealership told me they didn't need to duplicate the issue because I was the second car in for service that day for the same problem. Their solution is for me to plug my phone in for correct mapping. This sometimes works, but only is I do it in a specific order after starting the car - start the car, let it boot up the radio/entertainment/integrated map, unplug the cable, replug the cable, then plug my phone it. This is all with a bluetooth enabled car. I have requested for the dealership to test the GNSS module or replace it and they have not. They have said they are waiting for the investigation. meanwhile, I drive around and my car is given directions through backyards and fields. It is a hazard! This all started when the car was three days old.

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.

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 no one (the local Toyota Dealership, Engineer from Toyota Brand Engagement, or CEO office of Toyota Brand Engagement) is able to produce an idle specification sheet for the vehicle. They continue to state it is normal. Toyota Executive Office Case XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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. The vehicle was not repaired for the most recent failure. The manufacturer was made aware of the failure. The failure mileage was 2,000.

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.

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.

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.
