Car fire (total loss of vehicle) after hybrid malfunction. My family and I were traveling west bound on [redacted] near Crawfordsville Indiana on [redacted]. Trooper Chelsey Smith from the Indiana State Police (CAD # [redacted] ) came to the scene. Our car was traveling westbound at about 70 mph when I got a notification of "a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. Contact your Toyota dealer to have your vehicle inspected" - I acknowledged the alert and kept driving, then it showed again 30 seconds later and acknowledged again. About 30 seconds later I received a "Hybrid System Alert" stating "A malfunction in the Hybrid System has been detected. Stop in a save location and contact your Toyota dealer to have your vehicle inspected". …

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? …

As my wife had the wheels turned and was pulling up to the curb stop in a parking spot the car suddenly lurched forward without putting the accelerator on and went up and over the curb. Stop and hit a pole. my thoughts are is that the engine possibly changed from hybrid to gas or vice versa and as my wife's foot was let off on the brake to inch forward to the curb stop it suddenly lunged forward as previously stated.

This is regarding an issue with a 2022 Toyota Highlander with 79,668 miles at the dealership now waiting on a new transmission. On April 15, 2025, the vehicle was taken in to the dealership with whining noise and put on a diagnostic machine. Diagnosed as transmission. Took for second opinion at independent transmission company and stated the same issue. This vehicle is 4, 668 miles over warranty and we spoke with Toyota Brand Engagement and also district manager for this area. We are asking for help in replacement of this transmission costing over $10,000. Toyota was not willing to help in any way other than saying, "Sorry". We had to pay $5000 before the dealership would even order it. Now it has been three weeks and the transmission is still not at the dealership.We continue to make payments on a vehicle that is not even in service. …

While driving my 2022 Toyota Highlander (VIN: [redacted] , 29,427 miles), I have experienced multiple recurring safety defects that Toyota has been unable or unwilling to repair under warranty. Front collision sensors frequently trigger without any object present, creating a risk of unexpected emergency braking at freeway speeds. Transmission hesitates and surges unpredictably, sometimes propelling the vehicle into traffic. In heavy rain, my windshield wipers activated on their own and multiple system failure warnings appeared (including ABS failure), nearly causing a crash. Persistent startability issue when fuel is below half a tank. Seatbelt malfunction caused a passenger to strike their head. Seat heater failure, seat separation, persistent coolant odor, and nonfunctional factory wireless charger since purchase. …

I own a 2022 Toyota Highlander XLE (UA80E transmission, ~66k mi). The vehicle exhibits a severe transmission defect: uncommanded braking/drag at 35-40 mph and sudden loss of power when accelerating from a stop, making merging/crossing intersections dangerous. Two Toyota dealers (Bryan Toyota and Plano Toyota) reproduced the issue, documented the vehicle as unsafe to drive, and recommended full transmission replacement. The failed unit is preserved at the dealer for inspection. (Toyota Corporate Case #250917001779.) This mirrors long-standing defects within Toyota's UA80 family that Toyota itself has documented: Customer Support Program ZJC / POL19-04 (4/18/2019)-UA80 whine, harsh shifts, reduced power 2019 MC-10159730-9999 . T-SB-0160-18 Rev1 (12/17/2018)-UA80 whine/harsh shift/MIL/reduced power 2018 MC-10198131-9999 . …

I am reporting a premature transmission failure on a 2022 Toyota Highlander LE at approximately 85,000 miles. The vehicle began exhibiting a whining noise. When brought into the Toyota Dealership, I was notified that it needs a full transmission replacement. The vehicle was inspected by an authorized Toyota dealership, which determined that the transmission has failed and requires full replacement at an estimated cost of approximately $9,400. There were no warning lamps or messages of the problem prior to the failure. A transmission failing at this mileage creates a significant safety risk, especially when merging into traffic, accelerating from a stop, or maintaining highway speeds. This vehicle has been regularly maintained, with service performed through authorized Toyota dealerships. Despite this, Toyota has declined to provide assistance for the repair. …

To Whom It May Concern, I am submitting this complaint to report a serious mechanical issue involving the transfer case on my 2022 Toyota Highlander. This problem raises concerns regarding the safety, reliability, and overall performance of the vehicle. While driving, I began hearing a grinding noise coming from the vehicle. Concerned, I brought the vehicle to an authorized dealership for a diagnostic inspection. I was informed that there is a transmission-related issue and that the vehicle requires a transfer case replacement. At the time of diagnosis, the vehicle had approximately 77,000 miles and has been primarily driven locally under normal conditions. This type of major drivetrain failure at such mileage is unexpected and concerning, especially given that the vehicle has been properly maintained. …
