Clutch was feeling great on the drive home, but the clutch pedal got stuck to the floor after 20 min of driving. Luckily this happened after I was engaged to first, so I was able pull over. I pulled the clutch pedal back up with my foot and it seemed to gain pressure again. This happened once more on my drive back to the dealer. Each time I pulled the clutch pedal out, it seem to be OK.

Could this be CMC issue or air bubbles in the clutch line? It was a warmer day at +80F. Initially, the clutch pedal was very eager to come back to top and it got softer as the drive progressed.
