On September 23, 2026, at approximately 7:30 AM, I was driving the vehicle in a parking garage at an estimated speed of approximately 10 mph. While driving over a curve in the parking garage and applying the brakes to slow the vehicle and maneuver into a parking space, the vehicle suddenly accelerated on its own despite the brakes being applied. The vehicle struck the metal wire safety fence and then came to a stop. Prior to this incident, over the preceding 2–3 months, I had experienced intermittent problems with the transmission. Specifically, when shifting from neutral to reverse, the transmission would occasionally become temporarily stuck or fail to engage properly. It would then begin functioning after a small tap. What component or system failed or malfunctioned, and is it available for inspection upon request? : Possibly transmission How was your safety or the safety of others put at risk? There was no one else in the parking garage as it was early in the morning, otherwise it could have resulted in loss of additional property and possibly injuries.

Vehicle begin making grinding noises, and stalling during accelerating and also fuel smell. Took vehicle into Toyota Waldorf, MD dealership for diagnostic. At 58,000 miles, 2022 Toyota Highlander XLE stalls to accelerate due to front differentials failing, causing large chunks of metal on the drain plug indicating internal failure. Vehicle needs transmission and front differential replaced. I have 4 children, 3 of them still small, and driving with the fuel smell would impact them greatly as 1 of my children has asthma. It's also a hazard to be on the road with this vehicle as it can stall at any moment, causing a traffic incident. The problem has been reproduced by dealer, who is refusing to approve the fix under the 60,000 mile Power Train Warranty. There were no other warning signs, no check engine light came on, no issues prior to me hearing this grinding noise and stalling.

While accelerating, the vehicle produces a loud whining noise from the transmission area underneath the vehicle. I took the vehicle to Modern Toyota in [XXX] on XXX at 103,287 miles. The dealer diagnosed the condition and their invoice states the vehicle "needs the transmission replaced due to a gear whine." The estimated repair cost is approximately $10,498. This vehicle is equipped with the UA80E 8-speed automatic transmission. Toyota documented this same condition in Technical Service Bulletin T-SB-0008-21, which describes a whine or grind noise from the transmission caused by the front carrier assembly pinion shafts, and prescribes transaxle replacement as the repair. My vehicle exhibits the identical symptom and requires the identical repair. The vehicle is the original purchase, bought new on XXX. The failure occurred outside the 60,000-mile powertrain warranty limit, leaving the full repair cost to the owner. This appears to be a widespread defect affecting UA80-equipped Toyota vehicles across multiple model years, and I am reporting it so it is on record.

Because I am not an expert, I cannot say with certainty what exact vehicle components contributed to this incident. On August 17, 2026, at approximately 12:40 PM, I was slowly driving my 2022 Toyota Highlander XLE in a parking garage where I park my car every week. I saw a parking space, so I slowed down and began pressing the break as I went into the parking space. All of a sudden, the engine revved up, and the vehicle lunged over the wheel stop and hit the cement wall, even though I continued pressing on the break. I then shifted the gear into "Park" and turned off the ignition. It all happened so fast and was quite frightening. I, subsequently, inspected the damage; among other things, the hood, front bumper, fender, and some of the trim around the lights were damaged. The seat belt restrained me, but the air bag did not activate. My chest is still sore, and I have some bruising on my left shoulder. I have reported the incident to my insurance agency. On August 20, 2026, I took the vehicle to a collision repair center recommended by the insurance claims agent. I have another appointment on August 24th to have a different repair center inspect and asses the damages and give me a quote on the repairs needed. The experience was shocking, and I would not want this to happen to anyone, which is why I am reporting the incident. This kind of malfunction could have resulted in an injury to another human, so I am thankful that only my vehicle and I were affected. This unfortunate and alarming experience has definitely made me hesitant to drive the vehicle for fear of it malfunctioning again.
