You are mistaken.
There was a recall on certain mechatronics units where an internal bushing wore out prematurely. VW covered it and extended the warranty on those transmissions out a number of years. My car is covered under that warranty. So far I have no symptoms. If I do, all I do is take it in and my local dealer will verify it and replace it. Simple as that.
There have been only a handful of cases on any of the mkv boards I'm on where a transmission has needed to be completely replaced. I'm talking like a dozen or less here. Yes that does cost a pretty penny. But ask me if I'm worried about it and I'll tell you no, absolutely not.
