What are the symptoms of a faulty car clutch?

[Serena]

There are several main symptoms of a damaged car clutch: 1. Clutch slipping: When starting the car in low gear, after releasing the clutch pedal, the car either fails to start or has difficulty starting; during acceleration, the vehicle speed does not increase with the engine speed, resulting in a feeling of weak driving, and in severe cases, a burning smell or smoke may occur. 2. Incomplete clutch disengagement: Even when the clutch pedal is fully depressed, the power between the clutch's driving and driven plates cannot be completely cut off, leading to difficulty in shifting gears, gear grinding, inability to stop, or clutch overheating. 3. Clutch shudder: The entire vehicle shakes during startup, especially when idling and gradually releasing the clutch pedal in low gear, causing continuous jerking.
