NHTSA complaint #11397550, filed 2021-02, 173,943 miles“I was driving when I felt my brake pedal start to become soft and mushy. I was able to brake, but I had to pump the brakes to get full brakes to stop. I also noticed warnings began to appear on my dashboard. The warnings that were shown are the brake light, traction assistant light, and ABS light. I took it to Gates Toyota in South Bend, IN and paid for a brake inspection. They told me that my brakes themselves were OK (pads, rotors, calipers), but they were getting a C1391 error. I was told that the brake accumulator has an internal leak. …”

This is clearly a Hazzard and will cost lives to those who cannot afford the cost of repair.”
