Best Year to Buy?
Of the years with at least 100 tests, the 2021 model has the highest MOT pass rate at 97%, while the 2013 model has the lowest at 89%. The 2022 scores 97%, but cars from 2022 weren't due their first routine MOT until 2025, so its figure isn't compared here. Newer cars usually pass more often simply because they are younger, so compare years of a similar age.

About the 2022 Lexus RX
The 2022 Lexus RX is a premium performance car. Our records list a 3456cc hybrid engine, though engines vary between versions. 194 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. Among all models from 2022, the average MOT pass rate is 94%, and this model beats that benchmark.
With an average of 25,630 miles recorded at its 2024 MOT tests, Lexus RX owners cover more miles than the average driver. High-mileage examples should be checked carefully for wear on suspension, brakes, and drivetrain components.
2022 Lexus RX 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 2022 Lexus RX?
Total estimated annual running cost is £2,413 (£201/month), broken down as £1,958 fuel, £200 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 97% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
Lexus RX Reliability Trend
Newer Lexus RXs pass their MOT more often than older ones, by 5 percentage points on average, which is mostly down to age and wear.
Buying a Used 2022 Lexus RX
At 4 years old, the Lexus RX offers good value with plenty of life remaining. Most manufacturer warranties will have expired, so a pre-purchase inspection is worth the cost. If you're flexible on year, the 2021 model has the highest pass rate at 97%.
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
Low riskAfter 4 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
Low riskThe inverter converts DC to AC for the electric motor. Failures are expensive (£1,500+) but relatively rare. Listen for unusual buzzing sounds.
Regenerative Braking
Low riskBrake discs can corrode from reduced use (the electric motor handles most braking). Surface rust is normal but deep pitting needs attention.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
