One of the most common issues with i20s can be that the throttle position sensor (TPS) is damaged. The sensor is responsible for determining the opening angle of the throttle valve. This information is passed to the control unit, and contributes to the calculation of the amount of fuel required. A malfunctioning throttle sensor could cause rapid acceleration that is jerky, fluctuations in RPM and a reduction in engine performance.

Transmission problems are another common problem in the i20s. The transmission is a complicated component with a variety of gears that are connected to transfer the power from the engine. As time passes friction between gears could cause the transmission to suffer failure. Signs of a malfunctioning transmission include clunking, grinding noises and rapid acceleration that is jerky.

Spark plugs are a different aspect to be concerned about for the i20. A defective plug can cause engine damage by not giving enough sparks to each cylinder. If unchecked an unclean spark plug could cause serious and expensive engine damage.
