General Motors Co is facing increasing pressure to compensate victims for an ignition defect that prompted the recall of 1.6 million vehicles, even if some would-be plaintiffs are barred from suing the auto maker under the terms of its emergence from bankruptcy in 2009.

GM is a different legal entity than the one that filed the 2009 bankruptcy that shook the U.S. economy. The so-called "new" GM is not responsible under the terms of its bankruptcy exit for any legal claims relating to incidents that took place before July 2009.
