A malfunctioning throttle sensor could cause sudden acceleration, RPM fluctuations and decreased engine performance.

Another common problem found in i20s is the faulty transmission. The transmission is a complicated component made up of many gears that connect to transfer power from the engine to wheels. As time passes the friction between the gears can cause the transmission's failure. The sound of grinding or clunking and rapid acceleration that is jerky are signs of an unreliable gearbox.
