Badly build unit

I have my brand new polo less than a year and already the faults per month has reach .64. For a 2022 model this has become a very noisy car and while the service centre keep fixing a fault another one appear. Latest problem was a noise emitting from the left rear door, Tavcor fix it today 12/06/2023 which was a loose window regulator but they added 2 more problems: 1. Damaged window tint 2. Could not attach the door panel properly. My main concern is the cost and time that I must carry and further breakage when the car is out of warranty.
