About the 2017 Kia Optima

The 2017 Kia Optima is a family car. Our records list a 1999cc hybrid engine, though engines vary between versions. 5,853 MOT tests were recorded on this model in 2024, making it a reasonably common sight on UK roads. Among all models from 2017, the average MOT pass rate is 87%, and this model matches that benchmark.

With an average of 79,204 miles recorded at its 2024 MOT tests, Kia Optima owners cover more miles than the average driver. High-mileage examples should be checked carefully for wear on suspension, brakes, and drivetrain components.

2017 Kia Optima Fuel Costs

The 1999cc hybrid engine offers a reasonable balance between performance and economy. Our estimate uses around 36 mpg, the figure for a petrol engine of this size, which works out to roughly £1,631 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year). As a hybrid it should use less than that, and real-world fuel costs depend a lot on how much electric-only driving you do.

What does it cost to own a 2017 Kia Optima?

Total estimated annual running cost is £2,236 (£186/month), broken down as £1,631 fuel, £200 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 87% pass rate. Keeping on top of servicing will help avoid surprises.

Kia Optima Reliability Trend

Newer Kia Optimas pass their MOT more often than older ones, by 9 percentage points on average, which is mostly down to age and wear.

Buying a Used 2017 Kia Optima

At 9 years old, this is a solid used buy if you find one with good service history. Depreciation has levelled off, so you won't lose much more value. Focus on condition over mileage. If you're flexible on year, the 2020 model has the highest pass rate at 91%. With 5,853 MOT tests in our data, there's strong statistical confidence in these figures.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Hybrid Battery Health

Watch out

After 9 years, hybrid battery capacity may have reduced. A full replacement costs £2,000-£4,000, though reconditioning is cheaper at £500-£1,500.

Inverter and Power Electronics

Medium risk

The inverter converts DC to AC for the electric motor. Failures are expensive (£1,500+) but relatively rare. Listen for unusual buzzing sounds.

Regenerative Braking

Medium risk

Brake discs can corrode from reduced use (the electric motor handles most braking). Surface rust is normal but deep pitting needs attention.

Suspension Wear

Medium risk

Shock absorbers, springs, and anti-roll bar links typically need attention around this age. Listen for clunks over bumps and check for uneven tyre wear.

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.
