1 Automatic Emergency Braking problem

Failure Date: 11/05/2024

To start, on [xxx], I was going through an intersection on a country road and my automatic emergency braking engaged for no reason. My car stopped despite no other vehicle or object being in my way or anywhere close to me. I found it really weird but did not think much about after the fact. I have also heard a rattling noise under my hood since [xxx] and have reported this to Toyota and tried to have it fixed multiple times (and showed them videos) but they were never able to duplicate the noise so it has not been remedied. On [xxx] I was traveling on a highway during rush hour and the traffic in front of me came to a sudden stop. I braked as hard as I could; my automatic emergency braking did not engage and I rear ended the car in front of me (minimal damage to that car). We both immediately pulled partway onto the narrow left berm (we had both been in the left lane to get onto another highway). My car then turned off by itself and gave me an engine warning (I believe low engine oil- I had just had it serviced 3 days prior). The other car owner and I exchanged information quickly and decided to drive away because we were blocking rush hour traffic and it was dangerous. However, my car would not start back up. I called 911 and they came to use their vehicle to push me to the right side of the highway onto an exit where I was no longer blocking traffic. During the wait, I felt like I was going to die with traffic honking and swerving to avoid me. When the police officer was moving my car, the parking brake engaged when I put the car in neutral and would not turn off, so the smell of burning rubber was strong since the tires would not roll. Once the tow truck driver arrived he was able to use jumper cables to disengage the parking brake but the car still would not start. There were no prior warning lights. The car not starting was confirmed by the dealer- they are holding off doing maintenance to have an engineer check out the car and figure out what happened.

2 Automatic Emergency Braking problem

Failure Date: 10/31/2024

On [xxx], around 7:45 pm, my husband and I were driving on [xxx] from atlanta to visit family at john’s creek. We were driving at a steady speed of approximately 70mph on the second lane from the left when all of a sudden, the vehicle displayed a 'malfunction' alert and began swerving uncontrollably. Despite our attempts to regain control, the car swerved right, striking another vehicle three lanes away. We had no control over the steering or bringing the car to a safe stop. After colliding with the other vehicle, it then returned to its original lane and came to a sudden stop with a message displayed stating 'shifting to p'. During this incident, an sos call was automatically placed to Toyota, and we were subsequently connected to 911 through them. Our vehicle got damaged due to this and so did the other vehicle that got hit. The vehicle not only endangered our lives but was also a potential harm to others on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

3 Automatic Emergency Braking problem

Failure Date: 10/31/2024

We were driving on [xxx] near norcross, GA about 200 ft from exit [xxx] at a constant speed of around 70 mph, when suddenly the vehicle displayed 'system malfunction' and started veering on its own and the brakes wouldn't work. It kept veering to the right and crashed into a vehicle 2 lanes away and rebounded back to the original lane and came to a halt with a message displayed 'shifting to p'. The malfunction and loss of control, along with the brakes not functioning those few seconds/minutes put our lives and others' on the road at risk. The vehicle is available for inspection. The vehicle was towed on the day of the accident and then taken into a Toyota dealership and is currently there. The vehicle has not yet been repaired. Toyota sent a third-party inspector to gather data from the vehicle but that turned out to be merely the crash data up to 5 seconds prior by which time the malfunction had already occurred and the vehicle speed was down from 70mph to 31mph. The incident occurred on Thursday, [xxx]. We do not feel safe driving that vehicle again. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
