2004 KIA RIO 1.3L Petrol · FT04 AFA

A recurring pattern of front drive‑shaft CV boot deterioration, an oil‑seal leak and progressive rear‑sill corrosion defines this 2004 Kia Rio’s mechanical story; the 2025‑11‑19 MOT was passed but only with advisories on those very items, while earlier tests recorded a major stop‑lamp failure and a significant off‑side rear integral body‑structure corrosion defect that caused a failure in 2023. The trend shows that the vehicle has moved from outright failures to a pass‑with‑advisories, indicating that the most serious defects have been addressed or are now borderline, yet the underlying issues remain unresolved and continue to be flagged. At 44,804 mi the car averages roughly 2,000 mi per year, a mileage level that is low for a twenty‑two‑year‑old model. Such limited use often means reduced wear on wear‑items such as clutch plates, brake pads and tyre tread, but it also suggests the vehicle may have spent extended periods stationary, which can accelerate rubber hardening, tyre sidewall ageing and corrosion of body panels that are not regularly exposed to motion‑induced cleaning. The MOT record shows no large gaps between tests, so the low mileage is reflected in the relatively modest wear‑related failures recorded. Prospective buyers should give particular attention to the CV boots on both front outer drive‑shaft joints, which have been marked as severely deteriorated on every test since 2023. Look for grease or oil seeping from the boot edges, cracks or splits in the rubber, and listen for a clicking or whirring noise when applying torque to the steering wheel at low speed, which would indicate joint wear. A qualified mechanic should inspect the boots, replace them if necessary and check the condition of the CV joints themselves, as failure of the joint can lead to loss of drive or further oil leakage. The oil‑leak advisory, present on the last three tests, warrants a visual inspection for fresh oil spots under the engine bay and a check of the oil level and condition after a short drive; any steady drip could point to a failing valve‑cover gasket or oil filter housing seal. The off‑side rear sill corrosion repair and the earlier integral body‑structure corrosion note mean the rear chassis may have reduced rigidity – push on the rear corners while the car is on a level surface to feel for flex, and listen for creaking noises over bumps. Verify that the stop lamp now functions correctly and that the near‑side rear tyre cut has not deepened; a simple visual and tactile tyre inspection should reveal any progression toward a ply‑break. Addressing these specific items before purchase will clarify whether the car’s remaining life aligns with the buyer’s expectations.
