2012 Toyota Prius 1.8L Petrol · PL12 BHO

The latest MOT test on 2026-05-11 resulted in a passing grade, though it revealed several advisories that indicate ongoing wear and potential long-term concerns. The pattern of advisories over the past four years—particularly the repeated suspension arm pin or bush wear and tyre edge wear—suggests a maintenance trend that has neither significantly improved nor worsened, but rather highlights persistent, low-level degradation. The front suspension advisories from 2024 and 2026, in particular, point to progressive wear in the suspension components, which could lead to increased noise, clunking, or reduced ride quality if not addressed. The tyre advisories, while not yet at the legal limit, demonstrate a pattern of uneven wear and potential sidewall damage, which may accelerate further if not monitored. The vehicle’s recorded mileage of 68,499 miles at 14 years old represents a notably low annual usage rate of approximately 4,893 miles per year, which is atypical for its age. Such low mileage can result from infrequent use, long periods of stationary storage, or environmental factors like climate control settings that reduce wear. However, this profile also raises concerns about standing-related issues, such as corrosion in the brake systems, battery degradation from prolonged disuse, or fluid degradation due to lack of circulation. The absence of rapid mileage accumulation suggests that wear from driving has been minimal, but the vehicle’s age and low usage mean that time-based deterioration—such as brake pad corrosion, suspension stiffness, or fluid degradation—may be more pronounced than one might expect from mileage alone. As a prospective buyer, the advisories on the latest MOT warrant immediate attention, particularly the suspension arm pin or bush wear, which could lead to excessive movement, clunking noises when driving over bumps, or even suspension failure if left unchecked. On a test drive, listen for unusual suspension noises, particularly when navigating rough roads or sharp turns, and check for uneven tyre wear patterns that could indicate alignment or suspension issues. Inspect the suspension components visually for signs of excessive play or damage, and ensure the steering does not feel loose or binding. The tyre sidewall advisories suggest that the tyres may be nearing the end of their useful life, with potential cracking or perishing that could compromise grip and safety. Replace these tyres promptly, as sidewall damage is irreversible and can lead to sudden blowouts. In addition to the advisories, conduct a thorough physical inspection of the vehicle’s standing-related issues. Check the brake system for signs of corrosion on discs, calipers, or brake lines, as prolonged disuse can cause rust and binding. Inspect the 12V battery for corrosion on terminals, swelling, or reduced cranking power, as a dormant battery can lose charge over time. Verify that all fluids—brake, coolant, and transmission—are topped up and free from contamination, as time-based degradation can accelerate without regular use. Finally, review the service history for any missing or overdue maintenance, such as suspension component replacements or tyre rotations, which may have been deferred due to low usage. If the vehicle has been stored in a damp or extreme environment, also inspect for signs of water ingress, rust, or electrical system failures that could have occurred during prolonged inactivity.
