2nd complaint (first complaint - #10522765) - on July 2, 2013, around 5:20 P.M., my fourth incident of brake failure occurred. I was going about 5 miles and applied brakes. Brakes failed and engine sounded like it was racing. I crashed into a the rear of a sedan which was stopped. No injuries were sustained. We were able to drive the cars to a development to exchange insurance information. I drove the car to the dealership for trade-in since it was unreliable for driving at slow speeds. An earlier potential incident occurred in the morning when I was braking and slowing down to make a right hand turn, the individuals were crossing the street on which I was turning into and the brakes seemed to not engaged and the engine began to race. I applied more pressure on the brake pedal and the brakes engaged and stopped the car, barely. I am extremely disappointed in the lack of quality in the Toyota Avalon. I am also disappointed in the Toyota service center's Focus of the braking system without examining computer systems' engine controls and speed controls.
