NHTSA Complaint #11599257 — 2012 TOYOTA PRIUS

In 2019, I took my Prius in for service. I reported that when I suddenly brake, the pedal feels spongy as if the brakes will not stop vehicle and lights on dash lit up. Toyota did diagnostic, no action taken by service department at Toyota dealership. I have service history documentation. On June 29, 2024 we had routine maintenance and the service department of the Toyota dealership recommended brake fluid serviced. On July 1, 2024, I was driving my child home from his summer camp and when I tried to stop the brake did not work. I started pumping the brakes several times until the car slowed and came to a stop. The lights on the dash lit up again. The brake failure put my son and I in danger. We had the car towed to the service department of the Toyota dealership. The service department sent the following information after their diagnostic. "The warning lights re-appeared after we drove it a few times. Now regarding the brake fluid service we performed, it is not related to those warning lights. Your accumulator is internally failing. The accumulator is a computer that distributes and controls the amount of pressure going into the brake system, and the computer was not untouched. Unfortunately it was bad timing and the computer started to internally fail. These vehicle's are known to have bad brake actuators, and Toyota created a type of recall for it to get replaced under no charge. Unfortunately they only cover up to 10 years and your warranty expired last year." My husband and I did not receive information regarding this recall. We did an online search to find out more about this recall and found several pages and posts of people describing the same situation.
