Symptoms
- Pedal stays pressed down after releasing
- Have to pull the pedal back up by foot
- Clutch fluid reservoir low or empty
- Grinding when trying to shift after pedal sticks
Likely causes
- CommonLow or leaking clutch hydraulic fluidInsufficient fluid pressure can prevent the slave cylinder from returning the pedal.
- CommonBroken or disconnected pedal return springThis spring pulls the pedal back up; if it snaps or comes off, the pedal stays down.
- PossibleFailed clutch master or slave cylinderA cylinder that's seized internally won't return fluid to reset the pedal.
- PossibleObject or mat interference under the pedalA floor mat or debris can physically block the pedal's return path.
- PossibleBroken clutch cable (cable-operated systems)A snapped cable can leave the pedal without resistance or return force.
What to do
- Check for anything under the pedal, like a floor mat edge, that could be blocking its return.
- Check the clutch fluid reservoir level if the car has a hydraulic clutch.
- Try gently pulling the pedal back up with your foot to see if it moves freely or feels stuck/binding.
- Do not drive the car if the clutch won't reliably engage or disengage, since you may not be able to shift or stop safely.
- Have a mechanic inspect the pedal return spring, hydraulic cylinders, and cable (if equipped) if the issue isn't a simple obstruction.
- Replace whichever component is found to be broken or leaking.
- Bleed the hydraulic system after any repair to restore normal pedal feel.

When to call a pro
See a mechanic if the fix isn't an obvious obstruction, since hydraulic or cable repairs need proper bleeding or adjustment.
Safety
Use caution
Do not drive if you can't reliably engage or disengage the clutch; you could lose the ability to shift gears or stop the car from moving in gear.
