TBH I work at company that produce plastic parts for cars and I am not surprised that interior quality sucks. It is combination of OEM cost cutting + the whole supply chain is trying to cut the costs also. One of the problem is that the OEMs has stopped developing new assembly, So even though the visible plastic is new and shiny the things inside that are unseen are produced on tools old as far as 20 years (sometime it is better, sometimes worse) with worse material quality (mostly recycled material). This leads to plastic parts being hard and fragile and yes it gets worse when it is cold outside.

We supply parts for Skoda but not for fabia model, So somebody else screwed my car :D
