Car has stopped while pumping gas seems to be specifically after rain. There was a heavy rain and immediately after while pumping gas car was not able to start. Received message steering power low. Happened 3 times after first incident while pumping gas. Car was checked by a mechanic and believe it might be a defect with a part called purge flow ? After part was inspected all check engine lights and alerts on cars went away for a few weeks. Once again we had light rain and the same issue restarted , with unable to power car after pumping gas

2021 Highlander began with whining noise around May 15, 2026 and just outside the warranty. Had the vehicle inspected at the Toyota dealer for repair. They informed me the transmission failed and needs replaced for a price of $9600. Found on the internet that many folks are having the same transmission issue on several Toyotas made in 2021 with a UA80E or UA80F transmission. Toyota issued a Technical service bulletin (T-SB-0008-21) on FEBRUARY 9, 2021! We received no warning until the whining noise. We attempted a “goodwill case” to get Toyota to help pay but were denied for the simple reason we used our own mechanic. This has absolutely no effect on this transmission failure. Since Toyota was always aware of this issue I feel they should be held accountable. This is a major faulty product.

ELECTRICAL SYSTEM, LATCHES/LOCKS/LINKAGES:ELECTRONIC LOCK/LATCH ACTUATOR
The only door that will lock or unlock using the fab key or the master lock button on the drivers armrest is the drivers side rear door. My vehicle is not able to be locked unless I do it manually and can not be unlocked unless i use the rear drivers side door. This has been reproduced by the dealership. There were no warning lamps or messages and no other symptoms. This has been going on for a month. I am being told by the dealership service department that 3 actuators failed at the same time. My lift gate also malfunctioned this year. Dealership diagnosed it with needing new struts. Not sure if this is related. Lift gate would not open or open only a small amount. This was using the inside button and the outside one as well.

The transmission on the 2021 Toyota Highlander failed at only 5 1/2 years old (66,000 miles). This is a known issue from Toyota and they should be held responsible to cover items just barely out of warranty for well maintained vehicles.

SEATS
The driver’s seat lower cushion in my 2023 Toyota Highlander provided inadequate support during normal driving, particularly on the left side of the seat cushion where support for my left leg and hip area appeared insufficient. This caused uneven seating posture, increased discomfort, pressure, and difficulty maintaining a proper driving position during extended periods of driving. The seat became increasingly uncomfortable during prolonged use and caused pain, numbness, and difficulty maintaining a proper driving position. I am a professional driver and spend many hours operating the vehicle. Over time, the lack of support contributed to left-sided sciatica symptoms that required medical evaluation and physical therapy. Medical records document that prolonged sitting in the vehicle aggravated my condition and limited my ability to sit and drive comfortably. An independent upholstery specialist inspected the seat and determined that additional foam had to be added to the driver’s seat lower cushion to improve support and comfort. After the modification, the seat became significantly more comfortable. This indicates that the original seat cushion support may be inadequate. I believe this condition may affect other vehicles of the same model and should be investigated as a potential safety concern because it can affect driver posture, comfort, concentration, and safe vehicle operation during extended driving.

VISIBILITY:SUN/MOON ROOF ASSEMBLY
The contact owns a 2025 Toyota Highlander. The contact stated that while she and her husband were driving at 60 MPH, she heard a loud explosion noise from above her head and felt air whipping on top of her head. The contact stated that the sunroof exploded; however, the sunroof shield prevented the glass from entering the vehicle. The vehicle was steered to the side of the road and inspected, but the contact did not find anything wrong at that time. The vehicle was taken to a dealer where it was diagnosed that a rock may have hit the sunroof. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 8,498.

My 2023 Toyota Highlander was experiencing a high pitch whiny noise when accelerating. I looked up on line and saw that this could be a failing transmission issue. I took it into the Toyota Dealership , 6321 West Canal Drive, Kennewick, WA 99336. They confirmed my concerns. They said the transmission was toast and I could not drive it until repaired. They informed me they would have to order a replacement transmission under warranty. They further informed me that there is a backlog of requests for replacement transmissions because this is a major problem with Toyota. They have no idea how long it will be. It could be weeks or it could be months. In looking online, it appears that Toyota has been aware of this issue with the 8 speed transmission and has not been addressing the problem. My question, why isn't Toyota addressing this problem? Why does it take weeks or months to building a replacement transmission? Something needs to be done about this.

We purchased our 2021 Highlander XLE in the spring of 2024. It came with a powertrain warranty up to 60,000 miles. Unfortunately for us, we're at 65,000 miles and recently started hearing a high-pitched, whining noise when we accelerate. We took it to the Toyota dealership and they told us we need the transmission replaced. A new transmission is around $9,000, before taxes and service fees. We haven't had any other issues and haven't had an accident. There's already a class-action lawsuit against Toyota regarding their Highlander models having UA80 transmission issues. Because of this, we called corporate in hopes they will pay for it under their Goodwill Assistance program. However, because we never had the Highlander serviced at a Toyota dealership before, they told us they won't cover anything. We've routinely serviced this vehicle. We happened to purchase it at a Nissan dealership, so getting maintenance at Toyota didn't cross our minds. Regardless of where we got the car serviced, it's obvious there's a recurring problem with the Highlander's transmission that Toyota has refused to acknowledge, which is costing consumers around $9,000 apiece. We feel cheated by Toyota, and we hope they eventually have to make things right.

Subtle issues showed early when trying to accelerate to get on the freeway, the transmission would stall. It was intermittent so, difficult to show at the dealership. At around 50,000 miles I began feeling a drag in the transmission, like it was put in downhill mode. Again, it happened intermittently. At 60,000 it would lunge slightly forward when I put it in park. At 63,000 I started hearing a whining sound at acceleration. The dealership did not address my concerns until it was out of warranty and then they said I needed a new transmission.

STRUCTURE:BODY:BUMPERS
The contact's daughter owns a 2022 Toyota Highlander. The contact stated while driving approximately 65 MPH, the contact noticed an abnormal sound coming from the exterior of the vehicle. The driver pulled to a highway hot shop. Upon inspection, the contact noticed that the upper side of the lower front bumper cover had detached and the cover was hanging and dragging. The contact secured the cover with strings and was able to continue driving. The vehicle was taken to the dealer to be repaired under NHTSA Campaign Number: 23V720000 (Structure); however, the dealer refused to complete the recall repair due to collateral damage caused by the cover dragging. The vehicle was then taken to Toyota of Manhattan (679 11th Ave, New York, NY 10019), where the contact was denied assistance because the previous dealer had already opened a case. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was unknown.

I own a 2021 Toyota Highlander with approximately 100,500 miles. The vehicle has developed a noticeable whining noise coming from the transmission/drivetrain area that continues to worsen over time. The noise is most noticeable during acceleration and while driving at highway speeds. I brought the vehicle to Toyota for inspection and was informed that the issue is related to the transmission. However, Toyota denied repair assistance because the vehicle is outside the powertrain warranty period. After researching the issue, I discovered multiple similar complaints involving 2021 Toyota Highlanders equipped with the UA80 transmission, including Toyota Technical Service Bulletin T-SB-0008-21 regarding “Whine or Grind Noise From the Transmission.” The symptoms described in the bulletin closely match the symptoms my vehicle is experiencing. Toyota appears aware of this transmission-related issue, yet many owners outside the warranty period are being denied coverage despite similar failures and complaints. I am concerned this may represent a broader transmission defect that could lead to premature transmission failure, unsafe driving conditions, hesitation, loss of power, or expensive repairs for consumers. I believe this issue should be investigated further by NHTSA due to the growing number of similar complaints involving whining transmission noises and transmission failures in Toyota Highlander vehicles. At this time, the vehicle has not yet experienced a complete transmission failure, but the condition is worsening and raises significant concerns regarding reliability and safety.

My 2021 Toyota Highlander was making a high pitched whine sound upon acceleration with the sound level holding steady at a consistent speed. We took the vehicle to a Toyota dealership to have it looked at and were told the transmission needs to be replaced. No other warnings were received. We are concerned about our safety if the transmission goes out while on the road.

SERVICE BRAKES
The brakes on this vehicle disengage and re-engage at will during braking. There are no indications of when it will occur. Brakes will disengage during low and high-speed braking, braking while going uphill, downhill, on flat roadway or during turns. This has resulted in several near miss accidents as well as debris was struck in the roadway due to being unable to stop. This vehicle was purchased new from the dealership in NM and was reported to them starting at 18,000 miles. Vehicle has been taken to numerous dealerships and reported with them as well. Toyota's answer is this is normal. Brakes disengaging and resulting in near accidents is not normal. It is now pending formal inspection from Toyota corporate by dealerships dismiss the problem as unable to replicate. This is to the point where we only drive when absolutely needed due to fear of an accident as this is the only vehicle.
