One of the most frequent issues with i20s can be that the throttle position sensor (TPS) becomes defective. The sensor is responsible for measuring the opening angle of the throttle valve. This information is transmitted to the control unit, and contributes to the calculation of the amount of fuel required. A malfunctioning throttle position sensor will result in lower engine performance, jerky acceleration and RPM variations when driving.

Transmission issues are another frequent issue in the i20s. The transmission is a complicated component that contains a number of gears that work together to transfer the power from the engine. The friction between the gears cause wear and tear, which can cause the transmission to fail. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of a faulty gearbox.

Spark plugs are yet another area of concern for the i20. Spark plugs that are defective can cause engine damage by not delivering enough sparks to every cylinder. A damaged spark plug could cause expensive and serious engine damage if it is not checked.
