The throttle position sensor (TPS) is located in the i20, can be damaged. This sensor is responsible for determining the opening angle of the throttle valve. The data is sent to an electronic control unit, which is used to calculate the amount of fuel needed. A damaged throttle sensor can result in rapid acceleration that is jerky, fluctuations in RPM and reduced engine performance.

Transmission issues are another frequent issue in i20s. The transmission is a complex component that has many gears that work together to transfer the power from the engine. In time the friction between the gears can lead to the transmission's failure. The sound of grinding or clunking and jerky acceleration are symptoms of an inefficient gearbox.

Spark plugs are an additional area of concern for the i20. The problem with defective spark plugs is that they can harm the engine by not delivering the right amount of sparks to each cylinder. If they are not checked a damaged spark plug could result in serious and expensive engine damage.
