Chrysler's top PR executive is about to leave the company, sources tell the Wall Street Journal. David Barnas, will "join a new steering supplier being formed by Los Angeles-based Platinum Equity."

Since CEO Bob Nardelli came over from Home Depot last summer and cut communications staff, a number of others have left.

As we noted at the time, Jason Vines, the previous head of PR didn't last long, leaving this past December, followed closely by senior staffer Michael Aberlich.
