I have a 2016+ Cruze 6 Speed. I had that problem only once after doing a CDV Delete. It was the Slave cylinder leaking. Pop your hood, locate the brake fluid reservoir for the clutch system. Check it for leaks. Then follow the hose to the slave cylinder and check it for leaks. You should have someone pumping your clutch during this leak check. I replaced my slave cylinder and bled the system. No further issues.Recently, my gen 2 cruze’s clutch has been sticking to the floor. Sometimes it work. Perfectly, sometimes there’s absolutely 0 pressure and I can’t even drive my car, and sometimes it can be pushed in and will retract slowly or not at all. This just started happening after getting like a foot of snow for several days. Has anyone else had transmission, clutch, or gearbox problems in their manual trans cruzes?
