Since you have a 2014, has the clutch fluid been changed? Had a 2014 and I recall the Owner’s Manual says do it every 2 years. The 2017 Grand Sport says every 3.
It is not easy to do per the Service Manual. To get at the slave cylinder bleed screw, need to remove the left exhaust pipe and CAT, then screws holding the sheet metal cover. Dealers charge >$150.
I have been using what is referred to as the Ranger Method at every oil change. You can google but will provide a brief description below. Not as good as a bleed but if you don’t Track or drag race good enough, IMO. I used for 6 years in my C6, 3 1/2 in my 2014 C7 and will on my Grand Sport when I change oil other than the first I did at 500 miles. Worth a try for the OP.
Ranger Method
1) buy a small container of DOT 4 (don’t use fluid from an open container)
2) use a turkey baster etc to remove all fluid from the clutch reservoir (suggest putting a large rag around the opening as the stuff eats paint)
3) fill with new fluid
4) pump clutch 30 times
5) repeat steps above 6 to 8 times (might as well use all the new fluid then discard as it is very hydroscopic)
You'll see the fluid will look new on the last few cycles. You’ll also get a great left leg exercise!
