about failures

I have been wondering about The avionics and vacume failures. I have never had a new airplane my sr20 will be the first. But I have had 2 that were only a few years old. So I would not know by them. My questin to anyone is this. Have you or anyone you know had simuler problems with there new planes of any type. I have noticed that a guy with a small piper and a moony mse brand new had several isues. So maybe it is typcle of airplanes with so many systems. To have breakdown of equipment. I mean cars have problems also but for what we pay and cirus pays for the items in our airplanes why cant they have beter quality control. How can any of them make a profit. Just wondering.
