I own a 2020 Toyota highlander and the car mileage is 68,000 and the dealer told me my transmission is dead and needs to replacement. The cost for replacement is $13,000.00! I’m the first owner of the car and how could a new Toyota car transmission fail at 68,000 miles and the warranty is 5 yrs or 60,000 miles. This issue have to be Toyota manufacture problems and they should have a recall on this and I researched online and a lot of highlander owners have the same problems as me! NHTSA PLEASE RESEARCH AND HELP HIGHLANDER OWNERS! Thank you

I received a safety recall notice from Toyota (Recall No. 23TA15 / 23TB15) for the front passenger Occupant Classification System (OCS) sensors. The letter states that the airbag system may not deploy correctly and that the remedy is not yet available. I’m concerned for my safety and my passengers since the airbag system could fail in a crash. Toyota has not provided a repair timeline or an alternative vehicle. I’ve contacted my dealer and Toyota customer service but was told there’s no fix yet. I would like NHTSA to investigate the delay and require Toyota to provide an immediate remedy or alternate transportation. Symptoms: •Airbag light may remain on or system disabled •Unable to safely seat a passenger in the front seat •No repair currently available despite safety risk Remedy status: •Remedy not available

I brought my 2020 Toyota Highlander to Round Rock Toyota in 09/2024 for a failed transmission, referenced in TSB T-SB-0008-21. As of today, the vehicle has been in Toyota’s possession for over 10 months and remains unrepaired. My assigned case manager (Case #241003001730) has confirmed that Toyota has no ETA for the replacement part. I’ve also confirmed through Toyota’s customer support line that their parts department cannot provide a timeline. Toyota acknowledged the issue is tied to a known defect, yet there is no resolution. I was denied a loaner vehicle until escalating the issue to the dealership’s upper management. Toyota’s delay has caused significant personal and financial hardship. This is a clear breach of their powertrain warranty and represents a systemic breakdown in their ability to support affected customers. I am seeking immediate federal review of this issue, as it affects vehicle safety, value, and reliability.

While steering to the right to exit a parallel parking spot, the ABS sensor cable came into contact with a suspension bolt, snapping the sensor wire. This triggered the Check Engine Light and caused a malfunction in the braking systems.

The contact owns a 2020 Toyota Highlander. The contact stated while driving at approximately 25 MPH, there was an abnormal humming sound from the engine compartment. The contact depressed the accelerator pedal, and the sound got louder. The contact stated there was no warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 67,000.

My vehicle is started making a loud whining noise at around 78K miles whenever you accelerate between about 25-60mph. The dealer said that a new transmission is the only thing that would fix it. The cost of the transmission is 8K. The dealer said that Toyota ought to cover it, but I called and their initial answer is that they will not. This part should be recalled, there are multiple people online saying they are experiencing the same exact issue. This is a very expensive problem for this car, and not one that consumers should shoulder at low mileages.

Known transmission issue not being addressed. Internal parts issue and must be replaced after only a few years.

There is an open recall which has not been addressed in a timely manner. The below has been open since OCT 26, 2023. I have been advised that I would be notified when a remedy was available but it's been ten months with no solution. My front bumper detached while I was on the interstate causing damage to the front end of my vehicle. The subject vehicles are equipped with a resin front lower bumper cover assembly, connected with mounting tabs. If there is minor impact to the lower front bumper cover assembly that causes the mounting tabs to detach from the vehicle during normal operation, one or more parts of this assembly could detach, which could become a road hazard, increasing the risk of a crash or injury for other road users.

With 55k miles on a 2020 Toyota Highlander, we began hearing a whine. On various on-line sources it appears that this is not unusual among late teens to early '20s Highlanders. I brought the vehicle to the dealer (with close to 56k miles) and the dealer decided the transmission needs to be replaced. Even though the dealer service center acknowledges this is an ongoing issue w/the Highlander of this (late teens/early '20s) vintage I'm told its a 1-2mo wait for a transmission repair/replacement. Warranty is 60k miles... I was told be safe and don't go over 60k miles or its possible the warranty might not be honored. While currently operable, a quick internet search indicates, transmission failure often occurs unexpectedly, leaving drivers stranded on the side of the road. This situation can be not only inconvenient but also dangerous.

Coming to a stop or slowing down the vehicle has a spot where it feels like the brakes fail then come back on. Especially if going down a grade. This happens around 15 to 20 mph. Started off a slight moment when you are sure the brakes quit working for just a second. As the vehicle gets older it has brown to be more noticeable.

There has been an open recall WITHOUT resolution for over 6 months

The transmission has gone out. We noticed a whining noise which prompted getting the vehicle inspected which led to the diagnosis. The vehicle is at the dealership and cannot be driven as driving it will void the warranty. The were no warning messages just the whining noise at about 30-40 mph. We were told it was good that we caught it as the car could have broken down at any time which could have been a safety risk if it had all of a sudden stopped in traffic. We have researched and found that others have had the same issue. The transmission is on back order with no set arrival date.

The SRS airbag system malfunction went off and the seat keeps beeping for a long time before finally stopping I’ve taken it in to get fixed to the Stockton dealership but they said there’s no available fix yet, but then when I went to pick it up after my oil service they said for $200 they could fix it.

Rear AC lines are defective and are failing on vehicles releasing gas under the vehicle. Dealer has confirmed this is a known design issue caused by dissimilar metals between the vehicle, bracket and rear AC lines. Toyota has stopped supply of the defective part but has no solution to repair this issue yet. They have no solution other that to wait for a) Parts to be re-continued, b) wait for Toyota to release a design fix. Meanwhile I have a newborn and the car is unable to maintain a acceptable temperature for occupation

This is in reference to a 2020 Toyota Highlander. The Air Conditioner is not functional. Upon inspection by a mechanic, and $300 of freon wasted, it was determined that the lines that carry the AC to the rear of the vehicle are defective. Freon immediately drains. We have a case open with Toyota. The Toytota Case Manager acknowledged that the lines are a known issue, however at this time there is no replacement part available to fix the issue. The initial exchange with Toyota in early June resulted in a response that the part ETA was expected for early July. They have delayed twice since, to Late July, and now the status is pending with an ETA of late August but "subject to change." The vehicle is not drivable with the heat of Summer months; at times the internal temperature of the car is well over 100 degrees. I would anticipate people that live in southern year round hot climates with this issue can't drive it at all. My primary concern is having no AC is a safety issue for passengers, including children and an elderly family member [XXX]) for which I am a caretaker, and pets. Toyota did not respond to a request to provide a rental vehicle until the part is available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Loud screeching noise from stereo speakers. Very loud.

I was pulling into a parking space in a parking garage. As i was pulling in, the car unintentionally had a rapid acceleration event and crashed into a cement pillar causing the car to be a total loss

NHTSA, I mentioned to the service tech that I did have an error code appeared in my front dashboard display area momentarily and disappeared several times within the last 10 months. I was told that this would be address at this inspection of OCS (Occupant Classification System) sensor appointment. Doesn't this equate to a faulty OCS sensor and requires a replacement regardless of the testing of the sensor results today. If the error code was displayed in the past logically the sensor is failing and should be replaced. Does this make sense!!!!

Before hitting 100,000 miles the car started making a whirring/whine noise when accelerating. We mentioned it to the service advisor when taking the car in for an oil change. Initially the advisor said the service technicians took it for a drive and didn’t notice any noise; when we picked up the vehicle asked the advisor to sit in with us to point out the noise to him, he heard and acknowledged there in fact was a whining/whirring noise and said he would inquire about it to the shop foreman. The next day the advisor called me and said the shop foreman stated that noise is a transmission issue.

On numerous occasions when applying the brakes on my vehicle there is a very noticeable "surge" when the vehicle slows to a near stop. It feels like there is a momentary loss of braking before the brakes re-engage. I have had the vehicle since new and it seems like the problem has become more noticeable over time. I have lost some confidence in the safety performance of the vehicle due to this dangerous issue.

Loud whining noise after 55000 miles , Toyota saying i need a new transmission in my suv that now has 60785. I had alerted Toyota regarding the noise a month prior and they said it was a normal noise.

Transmission began whining and hesitating around 62K miles. Transmission is the 8AT.

There is a whining noise coming from the power train/transmission. It only happens when the accelerator pedal is pressed. We had a couple of mechanics look at it. The transmission oil was changed twice, with the vehicle less than 78,000 miles. Neither mechanic can find any issue with any other item, including the engine. The noise still persists. There are no warning lights on. We have researched the web. Toyota is aware of the problem and has replaced some transmissions still under warranty. They have issues a TSB (TSB008-21) in February 2021, but did not issue a recall or notify owners of a potential problem.

The vehicle continues to place excessive wear on the right rear tire despite the auto dealership service department stating there is nothing wrong with the vehicle. My tires have been replaced 4 times with 89,000 miles on the vehicle. The dealership service department is not willing to look into it any further and states everything is normal despite something clearly wearing this particular tire every 20-25,000 miles.

We were driving at around 70 mph on lane #3 on [XXX] near Auburn CA at around [XXX] on [XXX] with 2 passengers and some baggage in the trunk. No baggage were on the roof rack. Traffic was light and no vehicle was directly ahead of us at the time. Weather was cloudy. Suddenly we heard a loud bang above us, like a gun going off. I opened the sunroof cover and found the sunroof glass shattered. After exiting the freeway and parking, we found only the sunroof glass was damaged. The glass was shattered but still intact. There was no damage to the roof or roof racks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

8AT transmission failure. Toyota is telling me that it will take 7 months to obtain a replacement transmission.

The contact owns a 2020 Toyota Highlander. The contact stated while driving approximately 60 MPH, the contact depressed the brake pedal to slow for traffic. The contact stated that the vehicle was vibrating and as he depressed the brake pedal the pedal stiffened and required more pressure to depress. The contact stated no warning light was illuminated. The contact stated that the brake pedal failure occurred only between driving 60 to 70 MPH. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 87,000.

When coming to a stop the vehicle will often lurch forward. The lurch is powerful and could easily cause a collision. This problem occurs both when stopping in traffic and pulling into parking spaces. We were told by the dealer that the problem is caused by hybrid cars but we've had hybrid cars before that did not exhibit this behavior. It sounds like the dealership is aware of the problem but Toyota is not addressing it. This issue certainly poses a safety issue, especially for vehicles in front of the affected vehicle when attempting to stop.

Both front struts and bearing plates failed at 75k miles. They were leaking oil before that mileage. Approximate date of failure was 1/5/24. No parts were available until now. Parts were on back-order for upwards of a year for this model of Highlander in the FWD configuration, with 18” wheels. Prematurely failure causes a lot of bouncing in the car, therefore making the vehicle unresponsive to quick steering maneuvers. The bounce also made it so that typical driving within the city is dangerous as the bounce makes the car difficult to control. This is an issue that is documented on Toyota forums for FWD models. An accident has not been caused by this failure as of yet. Vehicle will be repaired soon. Mechanic was finally able to get two factory struts and bearing plates. Each strut is $200 and mounting plates are about $150 each. Parts + labor are expensive, but at least now it will be fixed.

The side view mirrors are very shaky at all speeds-- and worse over bumps/and/or at highway speeds. It causes a distraction in the peripheral vision of the driver, and does not provide a reliable, clear image in the mirror while the car is underway. The problem is worse on the driver (left) side, but it exists on both sides. This creates an unsafe condition where vision is not clear in the side mirrors.

Shortly after the powertrain warranty expired, the automatic transmission in my 2020 Toyota Highlander began producing a loud whining/howling noise during normal driving. The noise appears to come from the transmission area and increases with vehicle speed. The issue was not present during the warranty period and began unexpectedly soon after expiration. The abnormal noise raises concerns about internal transmission failure and potential loss of drivability. This condition could pose a safety risk if the transmission were to fail while driving, especially at highway speeds or when merging into traffic. No warning lights or messages were displayed prior to or during the issue. The vehicle was inspected by a Toyota dealer, and the problem was confirmed to be related to the transmission.
