These are issues documented for the Hyundai i20 in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

Body/Cosmetic · severity: Low mechanically (cosmetic only, does not affect drivability or safety) but potentially high in cost/inconvenience if a buyer is unaware the free-repair route exists and pays for a respray out of pocket. · confidence: 74/100 · 4 cited sources
Applies to: 1.2L Kappa NA / 1.4L Kappa NA / 1.6L Gamma NA / 1.4L CRDi turbodiesel / 1.4L Sport (85kW, SA-only UniChip remap) - not every engine this model has been sold with
ⓘ Not yet individually classified
Symptoms to watch for
Clear coat bubbling, flaking, or peeling - most commonly on the tailgate, roof, bonnet, and around the windscreen
Most reported on Polar White paint, though other colours have also been affected
In some reported cases, bubbling across the whole car rather than isolated panels
What To Check
Fully visible on a careful walk-around inspection in good light - check the tailgate, roof, bonnet, and windscreen surround closely, especially on white cars. Unlike many issues in this knowledge base, this one is straightforward to detect before purchase.
Fuel System (recall) / Engine (tensioner finding) - two distinct, real, unrelated findings · severity: High for the fuel pump recall - officially classified 'Serious (accident risk)' by the submitting regulator, since impeller swelling can cause sudden engine power loss and vehicle stoppage. Low to Moderate for the tensioner finding - a cold-start noise issue, not a safety-critical defect. · confidence: 56/100 · 3 cited sources
Applies to: 1.2L Kappa naturally aspirated petrol (61kW/115Nm) - SA launch spec / 1.0L T-GDI turbocharged petrol - SA launch spec - not every engine this model has been sold with
ⓘ Not yet individually classified
What To Check
The fuel pump defect may not present any warning symptom before a sudden failure - a VIN-based recall check is far more reliable than driving impression for this specific finding. The 1.0 T-GDI tensioner rattle, by contrast, IS genuinely detectable on a test drive that includes a real cold start after the vehicle has sat overnight (not one pre-warmed by the seller).
