2018 Toyota Prius 1.8L Hybrid electric · BM18 MLZ

The 2018 Toyota Prius has demonstrated a stable roadworthiness trend over the past three years, with all recent MOT tests—including the most recent on 31 March 2026—passing without any defects. The only notable failure occurred in August 2024, when the vehicle was tested at 85,563 miles, where the tester flagged degraded dust covers on both front anti-roll bar ball joints. This fault was rectified before the subsequent test at 85,570 miles, which passed cleanly. The absence of recurring advisories or defects in the most recent tests suggests that the vehicle has been maintained at a basic level, though the single suspension-related failure indicates attention to front suspension components was required at one point. The mileage accumulation of 128,017 miles over eight years—approximately 16,000 miles annually—is above average for a vehicle of this age, which may imply regular use rather than prolonged storage. The gap between the 2023 and 2024 tests (around 33,000 miles in 15 months) suggests consistent driving rather than sporadic use, though the 2024 failure at 85,563 miles—just seven days before passing at 85,570 miles—implies the owner addressed the suspension issue promptly. There are no extended periods of inactivity or unusually low mileage intervals to suggest neglect, but the high annual mileage will have accelerated wear on suspension bushes, brake components, and drivetrain fluids. Given the history, a buyer should prioritise an in-person inspection of the front suspension, particularly the anti-roll bar ball joints and their mounting points, as the 2024 failure indicates potential for further wear. The absence of other defects does not preclude gradual deterioration in suspension bushes, coil springs, or steering components over 128,000 miles, so visual inspection for play, corrosion, or uneven tyre wear is advisable. Brake discs and pads should also be checked for uneven wear or binding, as high mileage can exacerbate caliper sticking or rotor warping. Finally, the exhaust system and underbody should be examined for corrosion, especially around the rear subframe and wheel arches, given the vehicle’s hybrid nature and potential for fluid leaks or moisture ingress.
