They claim the subpoenas are too broad and would require them to hand over too much personal information, like personal phone numbers of dealer employees going back years. The group wants to make it clear that FCA has clarified its sales reporting and that the issue is with the manufacturer, not dealers. The dealers say that FCA employee records and testimony should be enough.

Although they've clarified their position regarding sales reporting, the fraud investigation continues full steam.
