General Motors on Thursday released the results of an internal investigation into the delayed recall of 2.6 million cars with faulty ignition switches. But the 315-page report doesn’t bring the issue to a close. Here’s what’s still to come in the ongoing recall case:

— CRIMINAL INVESTIGATION: The U.S. Justice Department is investigating GM’s conduct and may bring criminal charges. GM’s case is being investigated by the same team that got Toyota to agree to a $1.2 billion penalty for hiding unintended acceleration problems. That investigation lasted four years. The U.S. Securities and Exchange Commission is also investigating whether GM took too long to tell investors about the defective switches.
