Excessive whining noise, shift flare. The vehicle is only a couple of years old. I was told by the dealer that the transmission will likely need to be replaced. There are numerous complaints within the Toyota Nation forums. It was recommended that we report the incidents here, as having a large number of cars on the road with failing transmissions can certainly be considered a road hazard/safety issue.

The start/stop operating system failed. When the engine cut off while waiting for train to pass, the engine went to turn over and completely stopped the vehile. Although the car would not start, I was unable to cut the car off completely. It would say ignition on. The lights in vehicle were on. Running the ac caused the car to say high power consumption but there was no way to cut vehicle off without removing the battery to reset the vehicle. Caused the car to malfunction while sitting at a complete stop. Also cause the parking break to engage and I was unable to disengage parking break. A message came across saying parking break unavailable. My safety and others were put at risk because had it happened at any other time a crash would have been caused. It caused a roadway to be blocked off which caused confusion and near accidents.

I noticed in March of 2024 that the lower part of my bumper was starting to detach. So I brought my car in to get inspected while I was getting my car serviced. Their was a recall issues in 2023. When the dealership looked at my car they said their was no remedy for the recall that I would have to wait until their is one. They said they can not fix the car even though the lower bumper was already starting to detached. Now July 27, 2024. While driving the bumper fully detached and now I’m dragging the bumper underneath my car. Had to take it to a mechanic to get it removed and then saw my dealership to get it fixed because of the recall. Now My bumper got fully detached and I suffered because of this Recall problem. Dealership said they can’t fix the problem that it was because of a collision that happened from a previous owner of the car that got into a collision in 2021. Where I bought the car in 2023 where the bumper was not detached and now I’m suffering because the dealership said Toyota corporate won’t fix the car under the recall. Now I’m stuck with fixing a bumper where I never got into an accident and could of been injured because of this bumper falling while drive and I have to pay out of pocket to fix it.

The electric park brake makes a loud screaming sound during engaging cycle as I put the gear in park. The sound gets worse during warmer weather. I visited the dealer twice for the same problem and reported it to Toyota. During my visit another highlander came into dealership. It made the same sound when the driver placed it in Park. According to the dealer, this sound is normal. I say it’s not. I have way cheaper cars with Electric park and they don’t make this sound. If the park brake unit fails it’s going to be real costly to repair and may fail while driving and gets engaged.
