One of the most common issues with i20s is the throttle position sensor (TPS) develops a fault. The sensor is used to measure the opening angle of the throttle valve. The information is then sent to an electronic control unit, which aids in calculating the amount of fuel needed. A malfunctioning throttle position sensor can result in a decrease in engine performance, jerky acceleration, and RPM fluctuations when driving.

Transmission problems are a common issue with i20s. The transmission is a complex component that has many gears that work together to transfer power from the engine to the wheels. The friction between the gears cause wear over time which can cause the transmission to fail. Grinding or clunking sounds and an acceleration that is jerky can indicate a faulty gearbox.
