One of the most common issues with i20s is the throttle position sensor (TPS) is defective. This sensor is responsible to measure the opening angle of throttle valve. This information is transmitted to the control unit, which aids in calculating the amount of fuel needed. A malfunctioning throttle sensor can result in rapid acceleration that is jerky, fluctuations in RPM and reduced engine performance.

Another problem that is frequently found in the i20s is the malfunctioning transmission. The transmission is a complex part that has a lot of gears which mesh together to transfer the power from the engine. Over time friction between gears can cause the transmission's failure. The sound of grinding or clunking and an acceleration that is jerky can indicate an inefficient gearbox.

The spark plugs in the i20 are a different common issue area. A defective spark plug can damage the engine because they do not deliver the correct amounts of sparks to each cylinder. If left unchecked the damaged spark plug can cause serious and costly engine damage.
