General Motors Corp.’s hiring of noted claims attorney Kenneth Feinberg has raised the possibility that it might set up a fund to compensate victims of accidents linked to its recent recalls.

Prominent litigators said Barra was evasive and provided little new information about GM’s handling of ignition switch defects that prompted recalls of 2.6 million vehicles.
