Brake Master Cylinder problems of the 2010 Toyota Camry

In late August 2019 while returning home from shopping on a fast speed street I needed to slow down to make a turn and the break pedal went all the way to the floor, made a vibrating noise, the break light came on red and with the pedal going all the way to the floor and barely breaking I was able to go home, (about a mile), driving at 5 mph. Had car towed to dealer where they replaced master cylinder and power booster with cost of around $ 2,000. 00. The car only had 31,026 miles, all requested services were done on time or even before time, no sign of spongy pedal or breaks red light coming up for warning before this happening. We were very lucky to not crash the car in a bad accident or to be on a tallway. Lately I discovered emergency break not working, (never checked after repairs) while car left on drive and put emergency breaks, car moves. Certainly I will not return to dealer where I went since I bought the car, did they forgot to check the emergency breaks after breaks repair?as they had forgotten other thing after past services. Never Toyota again. When I talked to Toyota national headquarter I was told the dealer gave me a very good price and they partner with dealers. I asked if the would reimburse some since the car is not even at 36,000 miles and they told me the car is 10 year old! they would not do anything about it. This car has always been kept in the garage, driven weekly around and one day of the week driven at fast speed to keep everything in order. My car is like new, with all the care I take for, including keeping it washed. I never had in my life some like this happen, on any car I drove. . On 2/09/2010 there was a recall for service breaks maybe there was more cars than they listed. I read many complaints about same problem like mine but such cars seemed to have lots of more miles than me, sincerely, francesco martiradonna.
