About the 2004 KIA RIO

The 2004 KIA RIO is a small family car with a 1399cc petrol engine. 625 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. It sits in the bottom 94% of 2004 cars for MOT pass rates.

With an average of 68,036 miles at 22 years old, KIA RIO owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

2004 KIA RIO Fuel Costs

The 1399cc petrol engine offers a reasonable balance between performance and economy. Expect around 42 mpg in mixed driving, which works out to roughly £1,137 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 2004 KIA RIO?

Total estimated annual running cost is £2,087 (£174/month), broken down as £1137 fuel, £195 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 64% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.

KIA RIO Reliability Trend

Newer KIA RIOs show better MOT pass rates than older ones, with an average improvement of 17 percentage points.

Buying a Used 2004 KIA RIO

At 22 years old, the KIA RIO is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age.

Common Issues to Watch For

Based on the 2004 KIA RIO's fuel type, age, and engine size, these are the most likely problem areas to check.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Higher Than Average Failure Rate

Watch out

With a 64% MOT pass rate, this model fails more often than most. Budget for unexpected repairs and get a thorough pre-purchase inspection.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
