2021 Toyota Highlander

- The vehicle has been experiencing shifting issues (its an automatic vehicle) when driving in all instances and at all speeds that has progressively gotten worse over the past 4-8 weeks. - As it seems to be a transmission issue (and a known one pending litigation) the safety issue is if the transmission fails during operation of the car. - It was brought to a dealership to be inspected after it was initially felt as more of a vibration than the more harsh shifting/engine sounds and issues that it is currently experiencing. The dealership thought it to be the front hub assembly/bearing that was the issue. I had the front driver side replaced and the issue still remains and has continued to worsen. It has not been inspected by the manufacturer, police, or insurance representative. - There have been no warning lamps or messages at all. - Through research it appears this is a known issue with ongoing litigation (2 class action lawsuits currently in litigation related to UA80F transmissions of which it appears that our VIN is in the affected group).

We have been hearing whining coming from the front of the vehicle for months. Over the life of our time with this car, we have reported to Toyota multiple times about the sound, and about how sometimes the engine seems slow to shift. The whining increases as you press the gas pedal. Toyota is aware of this issue with Highlanders, but has told us they aren't going to fix it, as there is no recall on the issue. Turns out, there's a TSB related to the exact issue that we have with our Highlander. Now that we are out of warranty, we are looking at potentially replacing the transmission of a vehicle that Toyota has a record of intentionally avoiding to repair. Multiple independent service centers have confirmed the issue. They all have referred us back to Toyota because of the severity of the issue. There were no warning lamps or lights or the issue. However, the "whining" is audible every time in the vehicle.

Almost caused high speed accident merging onto toll road! The vehicle is experiencing a severe transmission slippage, shudder, and grinding noise, consistent with TSB-0008-21 (UA80 transmission failure). This defect causes hesitant acceleration and erratic shifting, creating a safety hazard when merging onto highways or crossing intersections. I am concerned the transmission will fail completely while driving, resulting in a sudden loss of motive power and increasing the risk of a crash. Toyota has covered this exact safety defect in 2017–2019 models (CSP ZJC) but has failed to recall the 2021 models despite identical symptoms. First reared it's head as slipping when putting vehicle in reverse, 25k+ ago. Was told by Toyota Certified mechanics it was an operator error. Morphed into larger issue.

Entering the freeway a mile from home the car would not properly excellerate, only reachind 40 mph before exiting the freeway in favor backroads to my appointment. Shaking back and forth while driving, exacerbated when braking and coming to stop, I needed to put the car into neutral to calm down the shaking while waiting for the light to change. I just went through experiencing a brake failure and reporting of that to this Agency and now see another of many defects associated with the 2020-2022 Toyota Highlanders and Siennas Toyota is not addressing through Recalls as they should be, and further frustrated this Agency has or chooses to have no means by which to enforce Toyota's responsibility to the public

Yesterday, as I do a couple times a month, I went to switch parking places, putting my 2021 Toyota Highlander where my 2007 Mazda was parked, in order to drive it and keep the battery from dying. After starting both cars I first moved the Mazda to make room for the Toyota. As I was slowly steering the Toyota at (idle speed) into the now vacant parking spot, the car accelerated on it's own, prompting me to hit the brakes, but to no avail. The car jumped the curb hitting, knocking over and and damaging a large ceramic planter and small tree in my neighbor's yard. My split second reaction upon having no brakes and a run away car was to push it out of drive, which ended up putting the car into reverse, causing a harsh jolt, followed by the car accelerating again on it's own, in reverse towards another neighbor's garage. I live in a condo complex, so all of this took place within about 30 feet of forward/backward/forward motion. My second split second decision (with no brakes) to avoid smashing into the garage was throwing it back into drive, which sent it accelerating back towards the parking place again. This time I had the presence of mind to push the power button on the dash, allowing me to barely come to stop before jumping the curb again. Whole thing lasted about 15 seconds. I had an appointment to attend, so after a brief conversation explaining to my (now outside) neighbor what happened, I left in the older car. Returning later in the day I found damage to the front of my Toyota and wonder if my transmission is damaged as well. I'm reimbursing my neighbor today. I've not attempted to drive the Toyota since, and am seeking your advice on how best to proceed, whether I should initiate contact with Toyota regarding this incident, or is that something you should initiate? Please advise. Thank you.
