Electrical

Prior to making a turn into a residential driveway, the vehicle throttled up and there was no response from the vehicle when the brakes were applied. The vehicle would not stop in motion. Based on my experience of this event, it is my firm belief that the vehicle shut down completely as a result to correct the throttle event, and the vehicle was not responsive to application of brake to bring the car to a stop. The safety and the safety of other was put at risk because the car would not come to a stop and the vehicle did not respond. If there would have been someone in the driveway, or this would have occurred on roadway, this would have caused catastrophic property damage, injury or death. The problem was not reproduced or confirmed by a dealer through a third party due to the fact that the independent inspection addressed only the hardware components of the vehicle and dismissed any examination of the ECU software or other software components in the vehicle. Manufacturer's reasoning was due to the fact that this was low impact (pulling into driveway) that the data recorder did not catch any relevant data. However, if the airbags would have deployed, sufficient data collected. This incident occurred on 5/30 at 206 miles in the same location where, (29) days prior to this event, I had pulled in / out of this same driveway under various conditions (other vehicles in driveway, empty driveway, etc) with no issue or incident. The engine throttled up prior to approaching my turn into the driveway, and the vehicle would not respond to the brakes. It was as if the vehicle shut down completely My new vehicle has been on order since October 2021, and was finally delivered to the dealership on 4/29/2022, which was six months later post to Toyota's active recall 21TB07/21TA07 issued for an identified Engine Control Unit (ECU) software in which the vehicle may falsely detect an error, shut down the hybrid system, causing a loss of drive power.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
On June 28, 2022 at around 20:10 PM, while on vacation at a resort in the Laurentian Mountains in Quebec, Canada, I went down to charge the car at the only charging station at the resort. It was being used, so I returned to our cabin in the D building. As I approached the building, I pulled up to clear a car so that I could park beside it. I slowed and before I could put the car in reverse, the car rolled forward a few inches. My foot was already on the brake so I pressed it harder. But the car continued to roll forward. It wouldn’t stop. When it finally came to a stop on the edge of a rock wall, it slowly rolled off the edge and dropped about 20 feet and rolled over coming to rest upright. I have photos and a video of the location and aftermath. The consumer stated she opened up an investigation with Toyota.

I called Toyota to let them know about the issue i have then Toyota told me the dealership will contact me within 24 hours and i am still waiting for more than a week. The issue is very serious and it's related to my life safety. Thanks
