2013 Toyota Prius Hybrid 1.8L Hybrid electric · LA13 HXY

This Toyota Prius has demonstrated a concerning decline in roadworthiness over the past year, with the most recent MOT test on 6 January 2026 revealing critical failures despite a clean history prior to 2024. The January 2026 test recorded two simultaneous failures: a near-side rear brake pipe corroded to the point of obstruction and both rear light lenses damaged, alongside a near-side headlamp aim adjustment. These issues indicate a sudden deterioration in maintenance standards, as the vehicle had passed all previous tests without fail since November 2024. The fact that the same brake pipe failure was noted in the same test—despite the vehicle being driven to the test centre—suggests either a chronic neglect of brake system inspection or a recent attempt to bypass proper servicing. The mileage progression reveals an unusually aggressive usage pattern for a vehicle of this age, with 346,650 miles recorded as of July 2026. Over the past year alone, the odometer increased by 7,800 miles between January 2025 and January 2026, averaging around 26,000 miles annually—a rate that accelerates wear on high-stress components like suspension bushes, coil springs, and drivetrain joints. Notably, there is a 13,850-mile gap between the July 2024 and January 2024 tests, followed by a clean stretch of three consecutive passes. This suggests the vehicle was either lightly used or stood idle during that period, only to be driven more heavily thereafter. The recent spike in mileage correlates with the emergence of critical faults, raising suspicion that the vehicle may have been pushed beyond its intended service intervals. A prospective buyer should prioritise an immediate inspection of the near-side rear brake system, particularly the corroded pipe and associated caliper mounting, as fluid leaks or binding calipers could pose an imminent failure risk. The damaged rear light lenses, while not directly safety-critical, indicate a lack of attention to minor but essential components—something that may extend to other wear items like wiper blades, windscreen washer reservoirs, and interior upholstery. Given the high mileage, the suspension should be thoroughly checked for worn or leaking shock absorbers, degraded bushes, and corrosion at ground clearance points, especially around the rear subframe. The hybrid battery system, though not directly flagged in MOT records, warrants professional assessment given the vehicle’s age and mileage, as degradation in hybrid components often manifests silently until critical failure. The structural integrity of the rear axle and floor pans should also be scrutinised for signs of rust penetration, particularly if the vehicle has experienced wet or salted road exposure.
