FYI I don't work for Fanatec so I only know what I know from emails I had with them and from various forum posts. They don't reveal much in emails I can tell you.
All companies are improving their products and I have no proof of anything.
The first CSW bases had a batch of bad motors and I guess that is a well known issue and has been taking care of.
I myself would have had the CSS SQ by now if it wasn't for that the last batch sold out before I had the time to put down an order.
I have absolutely no doubt that the CSS SQ is a brilliant piece of "gear"
and by the end of March one will be mine
The ones who gotten into problems with their Fanatec gear seems to make a lot of noise on the Internet but as usual the ones who enjoy their rigs keep on happily racing day after day.
It's like the analogy with a drop of oil can ruin a ton of water.
One things for sure, Fanatec is doing the best they can and they keep getting better and better.
