2012 Toyota Prius 1.8L Hybrid electric · LA12 UNZ

The 2012 Toyota Prius presents a stable and largely reassuring roadworthiness profile, having passed its most recent MOT on 4 June 2026 at 299,431 miles with only minor advisories. The maintenance trend is broadly consistent, with no dangerous or major defects recorded across the entire five-test history. The most recent test flagged an oil leak assessed as not excessive under item 8.4.1 (a) (i), along with a nearside front tyre worn close to the legal limit and worn on the edge under item 5.2.3 (e). Both are consumable-level concerns rather than structural or mechanical failures, and neither suggests neglect of the vehicle's core systems. The mileage accumulation tells a clear story of sustained high use. Between the December 2022 test at 239,679 miles and the June 2026 test at 299,431 miles, the car covered approximately 59,752 miles in just over three and a half years, averaging around 17,000 miles annually in that period. The earlier record shows a similar pace, with roughly 18,150 miles added between May 2023 and May 2024. This is well above the typical UK annual average and indicates the Prius has been driven hard and often, likely on longer commutes or motorway routes where the hybrid system performs most efficiently. The MOT record itself is clean and complete with no gaps, which supports the view that the car has been kept in regular use and tested annually without interruption. The recurring advisory pattern centres on tyre wear, specifically uneven edge wear on the nearside front in June 2026 and the nearside rear in May 2024. Edge wear on a single side typically points to suspension geometry issues, most commonly worn tracking toe settings or deteriorated suspension bushes allowing the wheel to run out of alignment. At nearly 300,000 miles, it would be prudent to have the front and rear suspension bushes, ball joints, and drop links inspected for play, along with a four-wheel alignment check. The minor oil leak noted in the latest test warrants underbonnet inspection to identify the source, whether a valve cover gasket, camshaft seal, or oil sump issue, as even minor leaks can worsen over time and contaminate other components. Given the high mileage, the condition of the brake discs, pads, and calipers should also be verified, as should the integrity of the exhaust system and any visible structural corrosion on the underside, particularly around suspension mounting points and subframes where fatigue accumulates over sustained high-mileage use.
