Used Hyundai i20 in Delhi

— The 7-speed DCT (dry clutch) on pre-2022 turbo variants has a well-documented issue of shuddering at low speeds, especially in stop-and-go traffic. The clutch pack overheats and wears prematurely. Test drive in heavy traffic for at least 15 minutes — if you feel vibration or hesitation below 20 km/h, walk away. DCT replacement is extremely expensive.

— On the 1.0 Turbo GDi, listen for unusual whistling or hissing sounds from the engine bay. If the car feels noticeably sluggish or the turbo lag is excessive (more than 2 seconds), the turbo intercooler hose may have a leak or the turbo itself could be failing. Check for oil residue around turbo connections. A dying turbo also produces blue/grey smoke on hard acceleration.

— The electric sunroof on Asta(O) variants has drain tubes that can get clogged with debris, causing water to leak into the headliner and cabin during rain. Check for water stains on the headliner fabric around the sunroof area. Pull back the A-pillar trim and check for moisture. Water damage to the ECU (located under the dashboard) can cause expensive electrical issues.
