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.

The contact owns a 2022 Toyota Highlander. The contact stated that while driving 20 MPH with a child seated in the rear passenger’s side seat with the seat back adjusted, while going around a roundabout, the vehicle was cut off by another vehicle, and the contact depressed the brake pedal aggressively to stop the vehicle. There was an abnormal clunking sound coming from the passenger’s side second-row seat, and the seat back moved or readjusted from the previous position. The contact slowed down to approximately 5 MPH to avoid the crash. The child remained secured in the car seat. There was no injury sustained. The vehicle was included in NHTSA Campaign Number: 26V128000 (SEATS). The manufacturer was notified of the failure, but the part was not yet available for the recall repair. The failure mileage was approximately 27,500.

FUEL/PROPULSION SYSTEM
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.

System Failed -Transmission makes a high pitch whine, which Toyota has identified as a product manufacturing issue with the 2017-2022 V6 Highlander, but has not done anything to rectify the issue for those of us out of warranty. As this transmission issue usually doesn't start happening until 60,000 miles, unless you bought an extended warranty, you're out another $8K to $10K due to their negligence. Found this on Redit - Toyota knows the UA80F whines—it’s in TSB T-SB-0160-18 , T-SB-0008-21 and CSP ZJC. But unless your VIN’s on their cherry-picked list, they’ll play dumb. Safety Risk - Transmission stops working and car is inoperable. Reproduced - Yes, Toyota is aware that several cars are affected and doesn't care. Symptoms - Identified Symptoms are high pitched whine, rough shifting, transmission slippage, etc.

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.

On XXX, I was driving my 2021 Toyota Highlander at approximately 55 mph when a deer entered the roadway and I had to brake suddenly to avoid a collision. My [XXX] daughter was properly seated in the second-row seat and was properly restrained by her seatbelt. During the braking event, the second-row seat unexpectedly folded forward while she was seated in it. As a result, my daughter experienced rib pain and soreness that lasted several days. After the incident, the seat was returned to the upright position and appeared to latch normally. The vehicle is subject to a recall involving the second-row seat. I contacted Toyota Customer Care on XXX, and Toyota provided a rental vehicle on XXX, while the recall issue is being addressed. I am reporting this incident because the recalled seat failed during an emergency braking event and resulted in injury to a child passenger.

Right after the manufacture warranty of 60K miles, the car began to make a humming noise. I took the car into the dealership with 65K miles on 13 Jun 2026, and the Toyota dealership stated that the humming is caused by the transmission and we will need to replace the entire transmission. The cost would be $9,447.29. This issue is known by Toyota and Toyota put out Toyota Service Bulletin (T-SB-008-21) but failed to issue recall for this defective transmission.

I am having a problem on the transmission as described by the Geras Magazine: "The issue stems from a flawed assembly process involving the counter drive gear support. A locking tab meant to secure a vital retaining nut was not bent properly during factory assembly. This leads to gear movement, internal wear, whining, and eventually failure."

On two separate occasions I was traveling approx. five to ten miles an hours and had to change lanes. Traffic was heavy and I had to accelerate quickly to do the lane change. The vehicle engine started to rev high and I was barely moving. It was like the transmission didn't know what to do. I had to let my foot completely off the gas for fearing I was going to blow something up. I advised Toyota On Nicholasville several times and they totally ignored me. Also occasionally the transmission will make a clunking noise when shifting in reverse. While this isn't as much of a safety concern as needing your vehicle to respond in traffic and it doesn't. It's very difficult to get Toyota dealers even to document what your concerns are. The way they see it, if wasn't documented, then it didn't happen. The transmission in this vehicle is not safe. You can't rely on the transmission to respond if you are put in a dangerous situation.

SERVICE BRAKES
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.

My vehicle has 67,100 miles. A whining/whistling noise recently started and the dealer has diagnosed that a new transmission is needed at a cost of $6,000-$8,000 and it is out of warranty. Researching this shows that this is a known manufacturing defect referred to under T-SB-0008-21. I am concerned that my transmission will fail while I am operating the vehicle.

AIR BAGS, LANE DEPARTURE: BLIND SPOT DETECTION, ELECTRICAL SYSTEM
Four days after I took delivery of this used vehicle (April 25, 2026), multiple warning lights appeared at once: BRAKE, ABS, PARK, Check Engine, Blind Spot Monitor Unavailable, and RCTA OFF. An independent Toyota dealership diagnosed the vehicle April 27-28, 2026 (approx. 109,000 miles) and found (1) water leaking into the rear hybrid battery area through a sunroof drain "installed incorrectly," causing a Brake System Control Module low-voltage code, starting issues, a headlight only partially functioning on one side, possible air in the brake system, and a musty HVAC odor; and (2) blind spot monitor fault code C1AC2 (Slave Module Horizontal Axis Misalignment) - the blind spot and rear cross-traffic monitoring systems do not function reliably. At a second visit on May 4, 2026, recalibration was unsuccessful; per Toyota procedure the only remaining option is replacing the right-rear blind spot sensor. The technician wrote the cause is a mystery, "whether it be body damage related or electrical short." Toyota service records show the same C1AC2 code was documented during the selling dealer's own pre-sale inspection, and that in December 2024 another Toyota dealership pulled the rear bumper and found the RR blind spot sensor bracket bent, causing incorrect readings - a recurring safety defect that prior calibrations and repairs have not resolved. Separately, federal safety recall 23V865 (occupant classification sensors; the passenger airbag may not deploy as designed) was open and incomplete when I purchased the vehicle and remains incomplete, and Toyota service campaign 25TD01 (rear traction motor cable corrosion) is also outstanding. The defect has been reproduced and confirmed by two Toyota dealerships, reported to the selling dealer in writing, and reported to Toyota's customer-care center. The vehicle is available for inspection upon request. No crash, fire, or injury.
