2004 Toyota Prius 1.5L Fuel cells · LL04 JOJ

The 2004 Toyota Prius received its most recent MOT test on 2026-08-22, where it passed with a single advisory regarding the near-side front upper anti-roll bar linkage ball joint exhibiting slight play, which is a critical component for lateral stability and suspension alignment. This latest result contrasts with the vehicle’s history of consistent advisories over the past six years, particularly those related to corrosion in coil springs, brake pipes, and structural elements, which have remained non-failing despite repeated checks. While the absence of failures in the last test suggests a stable maintenance profile, the recurring advisories—especially those tied to corrosion and suspension wear—demonstrate a pattern that warrants closer scrutiny, as they indicate underlying degradation that may accelerate without intervention. The recorded mileage of 98,048 miles for a vehicle aged 22 years represents an annual usage rate of approximately 4,457 miles, which is notably low for its age and reflects either minimal operational demand or prolonged periods of inactivity. Such low mileage can mask wear on consumables like brakes and fluids, as well as potential issues arising from prolonged standing, such as corrosion from moisture exposure or battery degradation. However, the advisories on coil springs and brake pipes suggest that even low-mileage vehicles can suffer from structural and fluid-related deterioration if not properly maintained, particularly in a climate prone to damp conditions. The combination of low mileage and repeated corrosion advisories implies that the vehicle’s wear profile may be influenced more by environmental factors than by high-stress usage. For a prospective buyer, the most critical areas to inspect during a physical examination include the suspension components, particularly the front upper anti-roll bar linkage and coil springs, which have shown recurring corrosion and play. Look for excessive sagging or binding in the springs, which could indicate further deterioration or failure, and listen for clunking noises when driving over bumps, as this may signal loose or worn suspension bushings. The brake system should be thoroughly checked for corrosion on the brake pipes, which could lead to fluid leaks or reduced braking efficiency, and inspect the front brake discs for pitting or scoring, which may require replacement if they continue to degrade. Additionally, the near-side rear brake pipe corrosion and grease buildup suggest a history of fluid exposure, so ensure the brake fluid is fresh and the system is free of leaks. Beyond mechanical checks, the vehicle’s low annual mileage makes it vulnerable to age-related issues that are less common in higher-mileage cars, such as tyre sidewall perishing, which has been noted in the MOT history and is a common problem in older vehicles exposed to UV light and temperature fluctuations. Inspect the tyres for cracks or delamination along the sidewall, as these can lead to sudden blowouts. The battery should be tested for voltage and capacity, especially if the car has been stationary for extended periods, as a weak battery can cause electrical gremlins or fail to start. Fluid servicing should be prioritised based on calendar intervals rather than mileage, with particular attention to the brake fluid, coolant, and transmission fluid, which can degrade over time regardless of usage. Finally, verify that the service book is up to date, as the absence of recorded service history for corrosion or fluid checks may indicate neglect, despite passing MOTs. A thorough inspection of the exhaust system and emissions components is also advisable, given the vehicle’s age and the potential for catalytic converter or sensor degradation.
