Vehicle failed

I went to take my car for a roadworthy certificate this morning and the car failed the test. We bought the vehicle from a dealership in Vereeniging in October 2021. The dealership only users Dekra Automotive. It was failed on upper control arm bush, a chip in the right front spotlight and difficulty selecting drive. All these could not be caused in a matter of 2 months! Why was this not picked up when the vehicle went the first time, and now suddenly there is a problem Our concern is that the same vehicle passed in October. We want to change the name of the owner of the vehicle.
