Check this exact carFrequently asked questions
Is the i20 reliable?
Broadly yes, it is a low-drama retail car with good warranty history.
What should I price in?
Rear discs on cars that have stood, and tyres.
Which trim moves?
Premium and Ultimate cars with the larger screen.
Do the engines use a timing belt or a timing chain?
Both the 1.2 MPI four-cylinder and the 1.0 T-GDi three-cylinder engines utilise a timing chain. While designed to be maintenance-free, they are highly sensitive to oil degradation. Ensure the service book shows regular, on-time oil changes to prevent premature chain stretch and costly tensioner failures.
What should I look out for on the Mk3 48V mild-hybrid models?
The Mk3's 48V system uses a Belt Starter Generator and a lithium-ion battery under the boot floor. Check that the start-stop system engages seamlessly without hesitation or belt squeal. Also, ensure the boot floor area is completely dry, as water ingress can permanently damage the expensive 48V battery unit.
Which automatic transmission is fitted, and are they problematic?
Mk2 1.4 models use a traditional, robust four-speed torque converter. Later Mk2 and Mk3 1.0 T-GDi models feature a seven-speed Dual Clutch Transmission. The DCT can exhibit slight hesitation at low speeds, but aggressive juddering when pulling away indicates worn clutch packs requiring an expensive replacement.
