About the 2012 Lexus GS

The 2012 Lexus GS is a premium performance car. Our records list a 3456cc hybrid engine, though engines vary between versions. 836 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. It ranks in the top 22% of all 2012 models for MOT pass rate.

With an average of 91,847 miles recorded at its 2024 MOT tests, Lexus GS owners drive about as much as the UK average.

2012 Lexus GS Fuel Costs

The 3456cc 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 2012 Lexus GS?

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 89% pass rate. Keeping on top of servicing will help avoid surprises.

Lexus GS Reliability Trend

Newer Lexus GSs 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 2012 Lexus GS

At 14 years old, the Lexus GS 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 2017 model has the highest pass rate at 96%.

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 14 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.

Clutch Wear

Medium risk

With an average of 92k 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.
