One of the most common problems with i20s is the throttle position sensor (TPS) is damaged. This sensor is responsible for measuring the opening angle of the throttle valve. This information is transmitted to the control unit and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle position sensor can cause a reduction in engine performance, jerky acceleration and RPM fluctuations when driving.

Another problem that is frequently found in the i20s is a faulty transmission. The transmission is a complex part with a variety of gears that interlock to transfer power from the engine to wheels. The friction between the gears causes wear and tear over time, which could cause the transmission to fail. Symptoms of a faulty transmission include clunking, grinding noises and rapid acceleration that is jerky.

Spark plugs are yet another area of concern for the i20. A defective spark plug can damage the engine because they do not deliver the right amount of sparks to every cylinder. A damaged spark plug could cause costly and serious engine damage if left unchecked.
