What 162 owners told NHTSA about the 2023 Toyota Highlander

My 2023 Toyota Highlander was grounded by the dealership on 4/30/26 due to safety recall 26TB06 (NHTSA Campaign 26V128) regarding a defective 2nd row seat back latch. The vehicle has been sitting un-remedied on the dealer lot for over 47 consecutive days. The dealership state they can't return the vehicle due to safety liabilities but have no estimated date for a remedy. leaving me stranded without my vehicle. The vehicle has been sitting completely idle on an outdoor lot. Per Toyota's manufacturing guidelines, leaving a hybrid vehicle sitting unused for more than 30 days risks severe high-voltage hybrid battery degradation and capacity loss. Because of the delay in remedy , my health of my vehicle is being actively damaged on my paid off hybrid powertrain. As a Disabled Veteran, Toyota's inability to provide recall safety parts has caused a severe, ongoing physical and financial hardship. By grounding my vehicle for over 47 days, I have been entirely deprived of using my state-issued Disabled Veteran's license plates. This strips me of critical, legally mandated toll exemptions, parking accommodations, and physical accessibility benefits that I require on a daily basis. Driving an inferior dealer loaner does not adequately remedy this disruption to my veteran benefits.

This 2023 Toyota Highlander XLE AWD has a recurring gasoline/fuel odor that began while the vehicle was still within the basic warranty period. The concern was reported to Toyota/dealer multiple times. At first, the odor was intermittent and difficult to duplicate, but the problem continued after repeated dealer visits. The fuel smell was later duplicated/confirmed while the dealer was open, before approximately 60,000 miles, but the vehicle was still not properly repaired. The odor has continued and recently occurred multiple days in a row. The smell has been noticed around/inside the vehicle and creates a safety concern because gasoline odor may indicate fuel vapor leakage or a fuel-system problem. Possible sources could include the fuel tank, fuel pump module or seal, filler neck, fuel lines, EVAP system, charcoal canister, purge valve, injectors, fuel rail, or another related fuel-system component. The vehicle has been inspected by a Toyota dealer multiple times, but the cause has not been identified or corrected. No warning light has clearly identified the source of the problem. The concern is especially serious because it involves fuel odor, possible vapor exposure, possible fire risk, and possible fuel-system failure. Occupants and others could be placed at risk if the odor is caused by a leak or defective fuel-system component. The dealer is now recommending removal/drop of the fuel tank for further diagnosis and quoted approximately $1,500 for that step. My concern is that full fuel-system diagnosis, including tank removal if needed, should have been performed earlier when the complaint was repeatedly made during warranty. The issue is not a new complaint; it is a continuing unresolved fuel odor concern that started during warranty and remained unresolved despite repeated dealer involvement. The vehicle and related components should be available for inspection upon request.

Toyota has an open safety recall/campaign for my 2023 Toyota Highlander, but the manufacturer/dealer has failed or is unable to remedy the recall in a timely manner. I am requesting NHTSA review the delay and lack of available remedy/repair.

When applying brake, in sporadic and unpredictable circumstances, the vehicle seems to switch from regenerative braking to brake pump braking. During this switch, braking power is lost completely. The vehicle was inspected by the Dealer, they stated no issues found / unable to reproduce. This issue, if unresolved, increases risk of vehicle collision. No warning lights, no messages, no other symptoms of the problem. This issue has been present for ~1.5 years.

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.

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.

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.

Right after vehicle passed 60k miles mark (manufacturer warranty ended) I noticed a whining noise under load. During acceleration the noise is most noticeable between 30-50 mph speed range. If a gas pedal released the noise is gone and if pressed again the noise is coming back. The pitch increases with a speed increase. I took the car to dealership (current odometer reading 61,037 miles) and they diagnosed transmission failure. Apparently it is a very common issue with the current transmission family (UA80/UA81).

Received a safety recall stating "Seat Back Reclinging Assembly May Not Securely Lock". Based on this information, it goes on to state that "a seat back that has not been secured in a locked position may fail to properly restrain occupants, increasing the risk of injury in the event of a crash at certain speeds." Currently there are no remedies available but it is advised that "no one sit in or use the second-row seats while the vehicle is moving until the remedy is performed on the vehicle." In speaking to headquarters as well as mutliple dealerships, the only "solution" is to provide a rental car in the amount of $42/day and they would reimburse in 6-8 weeks. There is no current remedy date. That would mean there is an out of pocket cost of $1200+ a month, in which these funds are not available to our family. I am the primary caretaker for two small children who are in car seats and required to utilize the back seat/2nd row. Since I have been advised not to use it, my car is currently unsafe to use for its intended purpose. I have been given no other solutions at this time.

2023 Highlander Hybrid braking suddenly changes at low speeds when coming to a stop. Vehicle's brakes work properly (Regenerative and hydraulic combined) until it slows to make a stop or slows in heavy traffic. Suddenly the brake pressure changes and the vehicle "lunges" forward and brake pedal must be pressed extremely hard to stop or slow the vehicle. Problem happens most often when on a hill approaching a stop. Toyota dealer initially said that they never heard of such a problem until I presented them with T-SB-0059-23 Hybrid Regenerative Brake Transition Feeling Improvement for Model years 2020 thru 2022 from Toyota's website. I had reported the issue 3 times before (twice while in warranty and documented by them once while in warranty) but they claim that there is no fix available and when and if one comes available it will only apply to vehicles with 36,000 miles or less. LOOKS like Toyota and this dealer could care less about SAFETY and its customers.

Some times when I request the rear hatch to open is does nothing but most of the time when I depress the close button, it moves less than an inch and then beeps. I have had to depress the button up to 6 times before the hatch closes. The car is only 3 years old as of this month and the problems stated more than 6 months ago but my mileage was over 36,000 6 months ago so it was out of warranty. This is a joke since my 12 year old suv has no issues with its powered hatch. There are a lot of online complaints on the power hatches. It is a safety issue of the hatches don’t close. This is almost a daily challenge (it not closing when I ask it to be closed (fob, rear hatch button as well as dash hatch button).

While driving down the highway I went over a bridge joint and my sunroof suddenly exploded sending glass both into and off the back of the vehicle. I was able to find the moment of the explosion on my rear dashcam (saw the falling glass) and checked the front dashcam for any evidence of an object that would have impacted and did not find any. Neither I or my two passengers saw an object hit. The front dashcam also confirmed rough pavement near the bridge joint that would have caused some vibration in the vehicle.
