2008 Suzuki SX4 sedan 5 speed 4 cylinder 2.0L 175,000 miles. Owned for 3 years. Never had a problem other than a/c going out. Drove 25 miles from my home to the neighboring town the other day. Once in town, I pressed the clutch to shift to neutral and clutch went all the way to the floor. No resistance. Couldn't shift into any gear. Coasted to a stop. Got out and checked reservoir. Fluid well above min. No obvious damage from what I could see. Car will shift into gears while it is not running and will start in first and is drivable but cannot shift into any other gears when running. Clutch pedal still has no resistance while car is running. Never had any problems with the transmission or clutch. No slipping, no noises, no shutter, no leaking, never have had to put any fluid in the reservoir since I've owned it, clutch has always engaged perfectly, pedal has had just the right resistance, changed transmission fluid earlier this year. No warning signs whatsoever. Have read a few forums that have said possible problems ranging from master cylinder, slave cylinder, broken clutch fork, bad pressure plate, air pocket and even worn clutch. I won't be fixing this problem myself. It's at a transmission shop at the moment. I just want to get a better idea of what it might actually be so I know what to expect when I go back to the shop and don't get taken, if you know what I mean.
