While driving my 2012 Toyota Prius, the traction control, brake, and ABS warning lights all came on at the same time. I used a home OBD scanner but it didnat show any diagnostic codes. After some research and inspection, I discovered that the issue was related to a faulty brake booster and accumulatora”something Iave learned is a common problem with this model. I was relieved to hear that Toyota has an extended warranty on these parts. However, last night while driving, the brakes suddenly stopped functioning properly. It became very difficult to slow down, which put me in a dangerous situation. Iam deeply concerned about the safety risks this defect poses and believe this issue deserves further attention.
