Volkswagen T Cross worst car I bought ever from VW Hatfield

Good day, I am so unhappy with the service i received from Volkswagen Hatfield in Pretoria. I bought a new VW T Cross 1.5 dsg R-line for over R450 000 and when i was taken delivery of the vehicle, everything went well. The f&I was really friendly and assisted me well but the morning of the second day, when i started the car, suddenly warning lights start popping up on the dash and my stop start function was disabled and my reverse mirror of the car was not working properly.

I reported this immediately to the dealership and i was told by the sales guy that its a problem they have with all the T crosses 1.5 dsg's currently in South Africa and VW South Africa was waiting for feedback from Germany regarding this problem.. My immediate response was, why was this never mentioned to me on the Friday when i had taken delivery of this car as well as the dipping mirror when you reverse, why was it not mentioned that you have to manually adjust the mirror every time you had reversed that it not re adjusting it self to the same position as before? They sell the cars on all these features but its not doing that! Now for a person spending almost a half million Rand on a car, this is leaving a very bad tast in my mouth and i want answers. I'm going to the Banking ombudsman now and i will go to social media with this as you promised a car that working 100% but was given a car that working only 70%. The car has 2000km on and now the handbrake is faulty as well. A new R450 000 car that's already faulty after only 2000km? Has Volkswagen quality gone down that much since my first VW Golf GTI 16V i bought a few years ago????

I want answers and feedback on my deal and on this car, if i was made aware of these issues before i bought the car, then i promise you i would have gone and bought another brand!.
