American Suzuki is filing for bankruptcy protection, and the mother ship (Suzuki Motor Corp) is leaving the U.S. market. This is not a surprise, as Suzuki's cars never really took off, and the brand remained nearly invisible.
If I had to pick a next brand to go, I think I would pick Smart (998 sales in Oct 2012) or Mitsubishi (3,981 sales in Oct 2012).
