A malfunctioning throttle sensor can cause rapid acceleration that is jerky, fluctuations in RPM and a decrease in engine performance.

Transmission issues are another frequent issue for i20s. The transmission is a complicated component with a variety of gears that are connected to transfer the power from the engine. The friction between the gears causes wear and replacement tear over time, which could cause the transmission to fail.
