2019 Lexus RX 3.5L Hybrid electric · KV69 UYN

The Lexus RX 450h with the 3.5-litre V6 hybrid powertrain typically returns around 35-40 mpg in real-world driving, though owners report figures closer to 30-35 mpg in mixed conditions. Fuel costs will depend heavily on driving style and journey type, with the hybrid system most efficient in town. As a Euro 6 DG vehicle registered between 2017 and 2020, it attracts a standard VED rate of approximately £150-£170 per year after the initial premium has expired, and remains exempt from the London ULEZ daily charge.

Insurance for the RX 450h typically falls into group 38-42E depending on trim, meaning premiums in the £500-£900 range for experienced drivers. Servicing through Lexus main dealers is priced higher than mainstream rivals but intervals are generous at 12 months/10,000 miles. Combined estimated annual running costs including fuel, tax, insurance, and routine maintenance sit in the £2,400-£2,900 bracket, which is competitive for a premium large SUV of this calibre.

Given the completely clean MOT record, the usual inspection checklist based on failure history is less critical here — but the model aggregate data highlights headlamp, tyre, and suspension arm issues as the most common MOT failures across the RX range. Check both headlamp units for condensation, lens crazing, and alignment, as replacement units are costly. Inspect all four tyres for brand consistency, tread depth across the full width (not just the centre), and any uneven wear patterns that might suggest alignment or suspension geometry issues. Even though no suspension advisories appear on this specific vehicle's MOT history, the model data shows suspension arms are a common failure point, so visually inspect the bushes and check for any knocking over speed bumps.

Beyond the MOT-relevant items, have the hybrid system professionally scanned for diagnostic trouble codes — particularly regarding the high-voltage battery State of Health, the hybrid inverter, and the transaxle. Test the engine start sequence to confirm a smooth transition between electric and petrol modes, and listen for any unusual whining or rattling from the hybrid drive area when stationary in electric mode. Check the rear brake discs for surface corrosion, as the regenerative braking system can leave them prone to rust buildup. Finally, verify all electronic features work correctly, including the infotainment, climate control, electric tailgate, and any driver assistance systems, as repairs outside warranty can be expensive on premium Lexus models.
