Okay, let me be the one to say it, almost out of warranty (powertrain), it’s causing you issues, and the market for used cars is nuts. All signs point to trading it in and getting something new, maybe the new GTI, Civic Si, etc?
The one good thing is it’s consistent so far. Nothing worse than an issue that comes and goes and always goes when you take it to the dealer. Do you get it serviced at the VW dealer here? If so, they likely made more off you owning it than the selling dealer.
Just to make you feel better, the time on the head unit in my GLI randomly changes time every few weeks. It is annoying as heck, but likely not worth the dealer to look into. Got to love those FGC electronics.
