A malfunctioning throttle sensor could result in jerky acceleration, RPM fluctuations and a reduction in engine performance.

Another issue common to i20s is the faulty transmission. The transmission is a complicated component with many gears that interlock to transfer power from the engine to wheels. The friction between the gears cause wear and tear over time, which could cause the transmission to fail.
