One of the most frequent problems with i20s is the throttle position sensor (TPS) is defective. This sensor is responsible for determining the opening angle of the throttle valve. This information is transmitted to the control unit and is used to the calculation of the amount of fuel needed. A malfunctioning throttle position sensor will result in a decrease in engine performance, jerky acceleration and RPM fluctuations while driving.

Transmission issues are another frequent issue with the i20s. The transmission is a complicated component made up of many gears that work together to transfer power from the engine to wheels. The friction between the gears cause wear and tear, which can cause the transmission to fail. The sound of grinding or clunking and jerky acceleration are symptoms of the gearbox being damaged.

Spark plugs are yet another aspect to be concerned about for the i20. A defective plug can cause engine damage by not providing enough sparks to each engine. If they are not checked an unclean spark plug can cause serious and expensive engine damage.
