A damaged throttle sensor can cause abrupt acceleration, erratic RPM changes and decreased engine performance.

Transmission issues are another frequent issue in the i20s. The transmission is a complicated component that has many gears that mesh together to transfer power from the engine to the wheels. The friction between the gears cause wear over time which can cause the transmission to fail. Signs of a defective transmission include clunking or grinding sounds and jerky acceleration.

Spark plugs are a different aspect to be concerned about for the i20. Faulty spark plugs can damage the engine because they do not deliver the correct amounts of sparks to every cylinder. A damaged spark plug can cause costly and serious engine damage if left unchecked.
