Brakes Failed problems of the 2010 Lexus RX

On September 30, 2018, about 7:00pm, driving slowly in a neighborhood, slowed even more to go over a speed bump, a light came on. Seconds later, when I went to brake to slow for a turn, there were no brakes. I had to push to the floor and the car barely slowed. My wife was in the car. Diagnosed as brake actuator and motor assist failure. Internet search revealed Lexus/Toyota has known this serious problem for many years of cars. A secondary warranty enhancement had been issued to dealers. Lexus won't honor it based on �customer loyalty� (our first Lexus). They didn't effectively warn and won't fix it. Brakes are as serious as it gets. There are thousands of cars out there like ticking bombs that could have brake failure at high speed or when a child is crossing the street. It's reprehensible that they won't fix it. Unforgivable that they won't issue a recall. Why? because the parts alone are $4,500 and our lives are worth less than that. Please do something. Reporting and asking because not if, but when, lives are lost due to �cost of doing business� I've done my part to make a record for the class action lawsuit. Shame on Lexus/Toyota.
