Clutch failure after oil change.
 

I have a 2009 with 21k miles So just got an oil change. When driving home I stopped to get some gas. And noticed the clutch pedal was just going to the floor. Luckily I was able to get home but then could not get it into gear. I had to push it in the garage. this could be a common csc failure ? I checked the fluid is still full. Is this coincidence it happened on the way home right after an oil change. Is there anything that they could have done wrong to cause this is what I’m thinking or just bad timing on a csc failure?? Thanks for the help in advance

Just bad timing on your part.

Sounds like an unfortunate coincidence. While you're in there, change both the slave and master clutch cylinder, just in case.
