I don't feel safe to drive my vehicle on the highway because the steering wheel ( the front end) very weak so when I drive the car it pull me to the left and to the right i went to the dealership where I purchased the car to check the vehicle, the technician told me that the steering wheel very sensitive and they cannot do anything about. 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

When adaptive cruise control is engaged and a car cuts in front of you the car will accelerate rapidly at first nearly hitting the car before it slows.

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.

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.

The vehicle went into drive from neutral after being placed on a moving track (car wash). The forward collision system activated and the automatic brake deployed when the vehicle sensed moving parts in the car wash. From there, the car automatically went out of neutral and into drive with no action from the driver. The vehicle drove forward and struck another vehicle.
