About the 2015 Lexus LS

The 2015 Lexus LS is a premium performance car. Our records list a 4608cc petrol engine, though engines vary between versions. 53 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. Among all models from 2015, the average MOT pass rate is 83%, and this model falls short of that benchmark.

With an average of 86,105 miles recorded at its 2024 MOT tests, Lexus LS owners cover more miles than the average driver.

2015 Lexus LS Fuel Costs

The 4608cc petrol engine is on the larger side, so fuel won't be this car's strong point. Expect around 30 mpg in mixed driving, 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).

What does it cost to own a 2015 Lexus LS?

Total estimated annual running cost is £3,153 (£263/month), broken down as £1,958 fuel, £790 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 81% pass rate. Keeping on top of servicing will help avoid surprises.

Lexus LS Reliability Trend

Newer Lexus LSs 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 2015 Lexus LS

At 11 years old, the Lexus LS 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 2019 model has the highest pass rate at 99%. Note: with only 53 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.

Timing Chain / Belt

Watch out

At 11 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.

Oil Consumption

Medium risk

Larger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.

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.

Clutch Wear

Medium risk

With an average of 86k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Brake Discs and Pads

Medium risk

High-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.

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.
