One of the most frequent problems with i20s is that the throttle position sensor (TPS) is damaged. This sensor is accountable to determine the opening angle of the throttle valve. The information is then sent to the control unit and contributes to the calculation of the amount of fuel required. A damaged throttle sensor can cause abrupt acceleration, erratic RPM changes and decreased engine performance.

Transmission issues are another frequent issue in i20s. The transmission is a complex component that has many gears that interlock to transfer power from the engine to wheels. Over time the friction between the gears could cause the transmission to suffer failure. Clanging or grinding sounds as well as an acceleration that is jerky can indicate an unreliable gearbox.

Spark plugs are a different issue for the i20. The problem with the plugs is that they can cause damage to engines by not sending enough sparks to every engine. A damaged spark plug could cause expensive and serious engine damage if not properly checked.
