Our Verdict
The Lexus RX 450h represented by SM71AAY
Given the clean two-test MOT record with no failures, your negotiating leverage on mechanical grounds is limited, but you should still commission an independent pre-purchase inspection focusing on the hybrid battery health, as the 3,456cc Lexus hybrid system can show degradation after five years. Pay particular attention to the tyres — both MOT tests flagged edge wear on multiple corners, which could suggest either an alignment issue or driving style, and budget for a four-tyre replacement if the current set is close to the legal minimum. Check that the service history includes the manufacturer-recommended hybrid system checks at 50,000 miles, and request documentation of any work carried out under warranty. The aggregate model data shows headlamp, tyre, and suspension arm failures as the most common MOT issues, so factor a budget of around £400-£600 per corner for genuine Lexus parts if any of these items are flagged in future.
As a self-charging hybrid, the RX 450h returns approximately 35-40 mpg in real-world driving, depending on conditions, which is competitive for a vehicle of this size and weight. Road tax is minimal thanks to the EURO 6 AP rating and hybrid powertrain, typically £0-£170 annually depending on the exact configuration registered. Insurance sits in group 40-45 for this model, placing monthly premiums in the £80-£130 range for a typical driver. Routine servicing every 12 months or 10,000 miles costs approximately £300-£500 at a Lexus main dealer, with hybrid battery inspections adding around £100 to scheduled services. Overall annual running costs, factoring in fuel, tax, insurance, and maintenance, are likely to fall in the £1,600-£2,200 bracket for a typical owner covering 10,000-12,000 miles per year.
The MOT history shows tyre edge wear flagged across both tests on multiple corners, so inspect all four tyres for uneven wear patterns and check the wheel alignment with a tracking gauge — uneven wear often points to suspension geometry issues rather than just tyre age. Inspect the headlamp units closely, as headlamp failures rank as the top MOT failure reason across the RX model range, and look for condensation, lens clouding, or failed LED modules which are costly to replace. Check the suspension arms and bushes for play, as this is the third most common failure type for the model, and pay attention to any knocking or creaking over speed bumps. Finally, for the hybrid system, ask the seller to display the battery state-of-health reading via a Lexus diagnostic tool, as the high-voltage battery is the most expensive single component on this vehicle.
This 2021 Lexus RX 450h (3,456cc hybrid powertrain, EURO 6 AP compliant) has completed two MOT tests without any failures, passing in January 2025 at 40,535 miles and again in January 2026 at 53,759 miles. Both tests recorded advisory items relating to tyre wear on the nearside and offside edges, but no components failed to meet the legal standard. The model as a whole demonstrates a 93.8% MOT pass rate across nearly 18,000 analysed vehicles, placing this example comfortably within that reliable cohort. Annual mileage on this vehicle is running at approximately 13,000 miles — below the model's reported average of 7,845? No, this vehicle's mileage of 53,759 over roughly 4.3 years equates to around 12,500 miles annually, which is above the model's reported average annual mileage figure.
The Lexus RX demonstrates one of the strongest reliability profiles in the large SUV segment, with an aggregate MOT pass rate of 93.8% across 17,892 analysed vehicles — notably higher than many German competitors in the same class. The most frequently recorded failure categories (headlamp, tyre, suspension arm) are largely consumable or wear-related rather than indicative of fundamental mechanical weakness.
