About the 2014 Lexus RX450H

The 2014 Lexus RX450H is a premium performance car. Our records list a 3300cc hybrid engine, though engines vary between versions. 39 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It ranks in the top 11% of all 2014 models for MOT pass rate.

With an average of 77,392 miles recorded at its 2024 MOT tests, Lexus RX450H owners drive about as much as the UK average.

2014 Lexus RX450H Fuel Costs

The 3300cc hybrid engine is on the larger side, so fuel won't be this car's strong point. Our estimate uses around 30 mpg, the figure for a petrol engine of this size, which works out to roughly £1,958 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 2014 Lexus RX450H?

Total estimated annual running cost is £3,003 (£250/month), broken down as £1,958 fuel, £790 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 95% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Lexus RX450H Reliability Trend

Newer Lexus RX450Hs pass their MOT more often than older ones, by 7 percentage points on average, which is mostly down to age and wear.

Buying a Used 2014 Lexus RX450H

At 12 years old, the Lexus RX450H 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. If you're flexible on year, the 2013 model has the highest pass rate at 92%. Note: with only 39 tests in our data, these figures should be treated as indicative rather than definitive.

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 12 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.

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.

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.
