VEHICLE SPEED CONTROL
when I attempt to accelerate from a stop, or slowly rolling, there is a 2-3 second delay, sometimes longer, prior to the vehicle moving forward. during the delay, when accelerator is pressed, the engine does not rev, nothing happens at all. it's scary. the highlander has less than 9k miles on it. this has been happening more and more frequently. I have contacted toyota, they have yet to provide a response or solution for this safety issue.

ENGINE, FUEL/PROPULSION SYSTEM, BACK OVER PREVENTION: WARNINGS
Two weeks ago, I had my 2022 Toyota Highlander serviced at Romano Toyota for my state inspection and regular maintenance. The dealership passed the inspection and did not mention any problems with my vehicle. However, just two days after the maintenance, the check engine light came on unexpectedly. The vehicle began to hesitate and shift roughly, with noticeable jerking during acceleration and delayed gear engagement. This created a safety hazard, especially when merging into traffic or crossing intersections, because the SUV would not respond quickly when pressing the accelerator. A diagnostic scan revealed transmission-related trouble codes (P2714 – Pressure Control Solenoid D, and/or P2757 – Torque Converter Clutch Pressure Control Solenoid Performance). I returned to the dealer, and they confirmed the issue but could not provide an immediate fix due to parts availability. They advised continuing to drive, which I feel is unsafe. The symptoms persist, and the transmission sometimes feels like it is slipping, which could result in loss of power in high-speed situations. This issue appears similar to other UA80 8-speed automatic transmission problems reported by Toyota owners from 2017–2022. Publicly available NHTSA records show over 200 similar complaints involving hesitation, rough shifting, and transmission failure. These reports suggest a potential widespread defect that may affect vehicle safety. Given the safety risk of delayed acceleration and possible transmission failure, I believe this defect needs investigation and corrective action.

POWER TRAIN
whine when accelerating. toyota has released a tsb 0008-21 indicating to replace transmission due to incorrect installation of a retaining clip on a nut securing differential in place. Nut can Become loose and stuck in gears of internals of transmission causing transmission to lock up while driving. this will cause loss of power and could result in an accident. Toyota is aware of the issue but refuses to make repairs due to vehicle being outside of powertrain warranty. Toyota has extended warranty to 10 years on 2017 and 208 model years however the problem still exist in 2017-2024 model years with the same transmission UA80E/UA80F

SEAT BELTS
Passenger seat belt won't extend half of the time. We have tried with engine on or off, put it in park and in gear, door open or closed and every other trick. We have pulled the belt straight up and down and every other angle. We have adjusted the height for tall or short riders. We took to the auto dealership, and they said it would not work for them at first then it started to work. We have had riders in the passenger front seat ride with no seat belt on because they couldn't extend it and gave up. It should work every time there because it is a safety issue that should be fixed.

POWER TRAIN
When our vehicle reached about 70,500 miles (10,000 miles past when the powertrain warranty expired), the vehicle started making high-pitched whining noises when the gas pedal was depressed. We brought it to the Toyota dealership and were advised that the vehicle's transmission needed to be replaced and were quoted $9,700. This is for a vehicle that was only 4 years old!! We do not feel that this is a repair/issue that a consumer must bear the cost of! When we shared this with the Toyota technician, he stated that unfortunately, the Highlander's powertrain warranty expired at 60,000 miles. We understand that Toyota was aware of this issue and this should have been escalated as a NHTSA recall where the manufacturer should be responsible for the cost of repair and/or replacement, not the consumer. Please assist us with obtaining a satisfactory resolution with this.

The contact owns a 2022 Toyota Highlander. The contact stated that while in reverse(R), the backup camera would intermittently fail to operate as the screen would appear blank. The contact also stated that the warning chime would fail to alert the driver to people or objects in the vicinity of the vehicle while reversing. The dealer was notified of the failure, and the contact was given an estimate for a diagnostic. After negotiating with the dealer, they agreed to reset the vehicle's sensors; however, the failure persisted. The manufacturer was notified of the failure, and the contact was informed that the backup camera was not covered under the warranty. The contact then stated that while backing out of a parking space, the back up system failed to alert her of her proximity to another parked vehicle; as a result, the contact crashed into a parked vehicle. The air bags did not deploy, no injuries were reported, and a police report was not filed. The vehicle was not repaired. The failure mileage was approximately 20,000.

The sunroof glass on our 2021 Highlander unexplainably shattered on our ride home on 7/20/25 at approximately 12:30PM. Sky was overcast, and the temperature was in the mid 80's. We had just entered the highway and were still accelerating to highway speed. We were not near a pedestrian overpass where a rock could have been tossed from above. Broken glass edges are pointing upward. The sunroof was in the fully closed position and not tilted. Safety would have been at extreme risk if we did not have the inner slide closed. The vehicle has not yet been inspected by the Toyota dealership or insurance.

SERVICE BRAKES, FUEL/PROPULSION SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was involved in a vehicle crash on 7-1-25. I had just pulled out of the gas station and was coming up to a stop sign so I was only going about 8mph I put my foot on the brake and nothing happened. I had my foot all the way down on the brake pedal because I saw a car coming and they were traveling at about 40mph. No automatic braking nothing worked. I had no control. I just prayed that I hope this doesn’t hurt. None of my airbags deployed. My car is now totaled and of course I got the ticket because I did not have control of my vehicle. I strongly believe this has to do with the brakes and how it switches from electric to gas in my hybrid vehicle. Toyota has recalled prior years 2020 to 2022 hybrids for this exact issue. This is a huge safety issue and thankfully I am alive to make this complaint. My husband went to my Toyota dealership where I get all my service and the service manager said yes he has noticed this as a problem that he himself pulled in a Toyota Highlander Hybrid into the garage and had the same thing happen. We have been reading online about others complaining of this same issue.

Our vehicle has 72k miles at normal use- no towing or off roading. Due to a whining noise we took in the vehicle at a Toyota dealer and after a $200 diagnostic fee concluded we need a new transmission priced at $10,800. There was no explanation/diagnosis summary- just we need a new transmission.

I purchased a 2021 Toyota Highlander in June of 2024 with about 45k miles. The transmission completely failed at 67k miles, when I brought it in to have checked in April of 2024. This is not covered under warranty and is costing 7-8k in repairs and over 3k in rental vehicles. I'm told the transmissions are on back order for 3-6 months. No lights went off in the car warning me of this. I smelled burning fumes on and off and reported it to the service dept around 59k (January 2024) miles. I did feel a jump at times, but didn't report that. After my routine oil change at the end of March of 2025, I heard a whining noise only when accelerating and would immediately stop when I released my foot. Two Toyota Service departments diagnosed my car with a failed transmission. I haven't been able to drive my car for 2 months now. My family's safety has been at risk while this issue with this transmission failure has been known and not reported to the consumers prior to my purchase in June of 2024. Potential consequences to a failed transmission while driving are as follows: -Sudden Stop or Coast to a Stop: The car might stop moving entirely, especially if internal components seize or it just loses power and I coast to a stop. -No Response to Acceleration -Pressing the gas has no effect, which is dangerous if I'd be in traffic or on a highway. -Locked-Up Transmission -Rare but possible, especially in catastrophic mechanical failure which could cause wheels to lock briefly. -Stranded

SERVICE BRAKES, ELECTRICAL SYSTEM
Vehicle: 2021 Toyota Highlander XSE Approximate Mileage: 92,000 Location: Boerne, TX (Texas Hill Country) ⸻ 🔧 Summary of the Problem: My vehicle experienced serious electrical failure after heavy rainfall in the Texas Hill Country, where catastrophic flooding recently occurred. At a red light, the dashboard began flashing, power windows stopped working, and the electronic parking brake would not disengage. I was nearly rear-ended with my children in the car because the vehicle temporarily lost responsiveness. ⸻ 💧 Pattern of Issue: This problem only occurs after rain. Once the vehicle dries out, the systems return to normal. Toyota tested the battery and alternator and found no faults. The dealership and Toyota Corporate have been notified, but they have so far refused to approve a Goodwill Repair or perform deeper inspection for water intrusion into the fuse box, firewall harness, or Body Control Module (BCM). ⸻ 🧩 Suspected Cause: I believe there is water intrusion due to a design flaw, likely through the windshield cowl or firewall. Other Highlander XSE owners have reported nearly identical symptoms following rain exposure. Toyota has issued service bulletins in the past about water reaching electrical components in other models. ⸻ 📣 Safety Concern: This is a serious safety issue. A near-crash involving my children occurred. If Toyota does not resolve this issue and it leads to an accident, I will hold them fully accountable. I am reporting this so it can be formally investigated and linked with similar complaints.

weather conditions were severe due to a snowstorm, causing ice buildup on the road, low visibility, and slippery pavement. Despite driving cautiously, I lost control of the vehicle, which resulted in going off the road, down an embankment, and crashing into a tree. Immediately after the impact, I called 911 emergency services for assistance. I attempted to exit the vehicle, but the driver’s door was blocked due to the position of the tree. I remained inside the vehicle until a passerby stopped and helped me get out. As a result of the impact, my vehicle sustained significant damage The shocking thing about it all is that the vehicle did not activate the airbags and that is worrying to me because it could have been unfortunate.

[XXX] [XXX] [XXX] [XXX] [XXX] Vin # [XXX] 2021 Toyota Highlander 4DR AWD XLE I am writing to report a potentially dangerous transmission defect in my 2021 Toyota Highlander XLE, at approx. 60-70k miles. The vehicle recently developed a high-pitched whining noise while accelerating, which a certified Toyota service technician suspects is internal to the transmission. This exact issue is outlined in Toyota Technical Service Bulletin T-SB-0008-21, issued February 9, 2021, for 2021 Highlanders equipped with the UA80E or UA80F 8-speed automatic transmission. According to the TSB, the cause is worn pinion shafts in the front carrier assembly, and the prescribed repair is complete transmission replacement. Unfortunately, my vehicle was just outside the 60,000-mile powertrain warranty window, despite experiencing the failure consistent with a known manufacturer defect. Numerous other owners have reported identical symptoms between 60,000–80,000 miles, often facing repair costs over $8,000 and multi-week delays due to part availability. This is not a typical wear-and-tear issue. A failure of the transmission at highway speeds or during critical maneuvers could lead to loss of power or control, posing a real safety risk to drivers and passengers. I respectfully urge the NHTSA to investigate this issue further. I am happy to provide: Thank you for your commitment to driver safety.
