Viking and Pfaff and Singers are owned by SVP Corp. But the Pfaffs still are engineered in Germany and same for the Vikings; engineered in Sweden but assembled in China for both.
I bought a brand new Viking Diamond Deluxe in May. In my 2nd class on using the machine the shop manager noted that the Exclusive Sensor System was not working properly when selected. She contacted the Viking Rep in the U.S. headquarters and was instructed to replace my machine immediately with another brand new out of the box machine. Never had a problem with the replaced machine and I have done lots of work on it since. I love love love this machine.
From what I understand the bigger main components are still manufactured in the country of origin but the rest is "made in China" and this broadens out further to other makes also, not just Viking and Pfaff, and including Bernina. In fact a former Bernina salesman told me that Bernina was already being made in China before Pfaff and Viking.
