I can not believe that practically a new car, has already the following brakes problems

:and the cost to high for my budget,, something has to be check by the company. Mechanic informed that Piston corroded, because part does not meet a design specification, calipers on left and right side no longer perform intended purpose, and disc hardware front corroded, affecting performance, and return Springs Rear worn affecting performance. Really I was surprise to hear all these, specially when I have a disable family member that I have take out for difference things. My question if did is ok for this car to have all these things wrong, specially the brakes?
