The edr report clearly showed that the brake oil pressure changes did not correlate with the progressively increasing vehicle deceleration. The issue is occasional, rare and cannot be reproduced every single time. This leads to disparity in assumed braking distance from routine experience by driving the vehicle and actual braking distance at the time of failed braking which supposedly may be as a result of inverter issues that are responsible for exclusively regenerative braking at low (<50 mph) speeds.

The car brakes failed at low speeds (10-15 mph) and bumped into the car in front in a stop-and-go traffic on the wet freeway after a recent rain. The brake pedal went all the way down to touch the floor, as if the brake pedal was disengaged from the braking system and the ABS light did not turn on at the time of braking. The car was driving in the straight line and immediately before this I was able to successfully brake the car on the very same trip. So the problem is intermittent. This is the second time with this car, as my spouse also experienced the similar brake failure at even lower speeds (<10 mph) resulting in touching the car in front and minor scratch on the bumper. It was a dry day then and almost similar circumstances. Associated geico claim number is 0423477190101054. We opened a case with Toyota to check the data recorder.
