My 2017 Diesel MT had a slave cylinder just go out last week. I stopped at a stop light after getting off the highway, and it wouldn't shift into any gears. The pedal kept getting stuck to the floor, and at first it seemed like the spring was the culprit. I had it towed to the dealer, and after the diagnostic they insisted it was the clutch plate and flywheel. After reading about the slave cylinder issues on this forum, I asked how that determination was made if they didn't take apart the transmission. Low and behold it was the slave cylinder, and the work is covered under the powertrain warranty. There is a TSB #PIP5558C that talks about issues with the clutch pedal sticking to the floor.
