2012 Hyundai I20 1.2L Petrol · BD12 PXU

The 2012 Hyundai I20 presents a stable and improving maintenance trend, with the most recent MOT on 08 July 2025 at 79,798 miles passing with only a minor defect. A single inoperative offside rear registration plate lamp was recorded, a trivial electrical issue with no mechanical significance. The vehicle has not failed a test since July 2024, and the 2025 clean bill of health suggests the previous exhaust fault was properly remedied rather than patched temporarily. The mileage pattern tells an unusual story. Between the 2024 and 2025 tests, the car covered just 4,098 miles in a full year. Before that, the annualised rate sat closer to 6,000 miles, which is already low for a supermini of this age. The sharp drop in 2025 raises the possibility of prolonged periods standing, a change of owner, or a shift to very short local journeys. Low annual mileage can mask deferred servicing, dried-out rubber components, and condensation-related corrosion that high-mileage cars driven regularly tend to avoid. The 2024 failure centred on a major exhaust leak at the offside rear, accompanied by a Lambda reading outside specified limits after the second fast idle. This points to a compromised exhaust system affecting emissions control, likely a cracked manifold, failed gasket, or corroded section. The fact that the 2025 test recorded no exhaust-related defects indicates a repair was carried out. A buyer should still inspect the full exhaust system for fresh welds, replacement sections, and signs of ongoing gas leakage around joints and flexi-pipes. Beyond the exhaust, the 2022 advisory regarding a deteriorated nearside front lower suspension arm ball joint dust cover warrants attention. Split or perished gaiters allow ingress of water and grit, accelerating ball joint wear and potentially leading to costly suspension failure. The tester did not re-flag this item in subsequent tests, but the absence of a follow-up does not confirm a repair was made. A physical inspection should verify the condition of all suspension gaiters, track rod ends, and wishbone bushes, along with any evidence of corrosion on subframes and suspension mounting points given the car's age and low-use profile. Brake condition should also be checked, as infrequent use can lead to binding calipers, uneven disc wear, and deteriorated brake fluid from moisture absorption.
