if you can find chrysler tsb #06-002-07, it talks about the clutch throw out bearing having an incorrect pre-load condition. this would effect (some of) the '07 model year. w/ the nsg370 trans, sales code deh. it wants you to do several tests then reccomends a few parts to replace. cluch slave actuator rod, some washers, and a new throw out bearing.
go see your selling dealer, it may be covered under you powertrain warranty if you've got one. hope this helps.
*edit* link for another site. sorry if this breaks any rules.
