2025 Lexus RX 450H+ Premium Plus Phev CVT Hybrid electric (clean) · LR75 WDN

Because this 2025 Lexus RX 450h+ Premium Plus PHEV CVT has no MOT history on file, the defining mechanical story is one that simply cannot be told from testing data. UK legislation does not require an MOT test until a vehicle reaches three years of age, and with the car being only one year old in September 2026, it has not yet entered the annual roadworthiness testing cycle. There are therefore no pass or fail outcomes, no advisories, and no recorded defect patterns to reconcile. Any narrative about long-term mechanical condition would have to be constructed without the principal piece of evidence used to judge used vehicles on the UK market. Mileage data is likewise absent from the records supplied, which prevents any meaningful analysis of annual accumulation, usage intensity, or gaps between tests. Without a recorded odometer reading at an MOT station, there is no DVSA-verified baseline against which to judge whether the vehicle has covered a typical first-year mileage for a plug-in hybrid or whether it has been used unusually sparingly or heavily. For a PHEV in particular, this gap matters because usage pattern directly influences the wear profile of the combustion components, brake discs and pads (which see less work under heavy regenerative braking), and the 12V auxiliary battery, which can suffer if the vehicle is left parked for extended periods without being driven through a full charge cycle. None of these factors can be confirmed from the official record. Given the absence of MOT history, a prospective buyer cannot rely on any documented advisory or failure to focus the physical inspection. The practical approach is to confirm the mileage independently through the dealership or previous owner documentation and to scrutinise the high-wear items that a one-year-old luxury PHEV might still legitimately develop, such as early signs of brake disc corrosion on a car that has done much of its slowing through regenerative braking, and any wear or scuffing on the multi-spoke alloy wheels that may hint at kerbing incidents not recorded in any test. The plug-in hybrid system itself, including the charging port condition, the high-voltage cable, and any warning messages on the driver display, should be checked before any commitment. On the move, the buyer should listen carefully for any suspension noise from the front strut tops or rear bushes over speed humps, which can manifest as a clonking or creaking even on relatively new vehicles if the roads have been particularly poor, and feel for any steering vibration or pull that could indicate a wheel alignment issue rather than a mechanical defect. The CVT transmission should be checked for smooth, step-free response both at low speed and under hard acceleration, while the brake pedal should feel firm and progressive without any grinding or judder that might indicate a binding caliper. Finally, because PHEVs carry two distinct energy systems, any hybrid system warning, range discrepancy on the electric-only range, or inability to charge should be treated as a primary negotiation point, as these items sit entirely outside the scope of what an MOT will ever record.
