I have a '14 Dart rally 6 speed. I've had the clutch pedal sticking to the floor problem occasionally. It always happened when first starting the car after it was parked, I'd pry it up with my toes and after feeling strange for a brief time it would return to normal.
I received a letter last winter from FCA saying some manual Darts and maybe another model like the Compass, had this problem and they were extending the warranty on the hydraulic clutch system to 60K miles iirc.
The problem with mine has been off and on, but it's been around a year since it last occurred on my car.
Hoping the problem is resolved itself on mine, but will be taking it in for the recall if it happens again.
