I was involved in an auto accident on 4/20/2026 @ 6:23 PM. I was driving a 2006 Prius and the vehicle in front of me stopped to make a left turn. I applied my brakes, which grabbed slightly and then released. I then had to hit the brakes hard and they did the same thing again. I ended up rear-ending the vehicle in front of me and had to go to the hospital. Iâve been out of work since the accident, and I feel this was not my fault DUE TO FAULTY BRAKING SYSTEM ON THIS VEHICLE. My vehicle was declared a total loss, by the insurance company After doing my own research I have found many accidents with this type of vehicle that has had rear end accidents with injuries and some fatalities. it…

I am looking to receive a little bit more assistance regarding my daughter's first car that she worked very hard for. It is a 2006 Toyota Prius. It was garage-kept and owned by an older couple who only put 85,000 miles on it. It is really a gem of a car. Soon after we registered the car, my daughter was out driving with her father. While going through a 4-way stop, she found that the brakes had failed and she was unable to stop at the intersection. Luckily, she was with her father, and he was able to give her verbal instruction to guide the both of them to safety. Upon further investigation, we learned that there was a recall on the Brake Actuator Assembly in 2016. Which is the part that…

The following describes a near total failure of the brake system that accompanies and is triggered by routine aging of the battery. I believe this applies to multiple model years and editions of the Prius, based on reports by other owners on owners' discussion groups. I believe this should have the highest severity level. Here is what happens: An alarm is sounded, several warning lights ABS, VCS appear, and soon after that, the front brakes stop working. The rear brakes then prove ineffective and lock up. The happens with high frequency under any of the following conditions: (a) as the battery approaches 3yrs age, (b) it is excessively cold outside. (c) there is a higher than typical load…

The light up display for the odometer, fuel gauge, and speedometer does not always light up. When it is not lit, the cruise control and any warning and informative alarms/lights also do not work. This is a well-known issue among owners of these cars, related to the capacitors on the circuit board for the display being defective, and there is extensive documentation of it online. It may also have had a technical service bulletin released for the issue, but I'm not entirely sure. The light goes out intermittently and is not always consistently out. I did mention it to the service personnel when I took it in to get recalls repaired recently, and they didn't seem surprised or unaware of the…
