One of the most common problems with i20s is that the throttle position sensor (TPS) becomes defective. This sensor is responsible for determining the opening angle of the throttle valve. This information is sent to the control unit and is used to the calculation of the amount of fuel required. A malfunctioning throttle sensor could result in abrupt acceleration, erratic RPM changes and reduced engine performance.

Transmission issues are another frequent problem in the i20s. The transmission is a complex component that has many gears that work together to transfer power from the engine to the wheels. As time passes, the friction between the gears can lead to the transmission's failure. Signs of a defective transmission include clunking or grinding sounds and rapid acceleration that is jerky.

Spark plugs are a different issue for the i20. The problem with defective spark plugs is that they can harm the engine by not delivering the correct amounts of sparks to every cylinder. If they are not checked, a damaged spark plug can result in severe and expensive engine damage.
