2004 Toyota Prius 1.8L Hybrid electric (clean) · LS54 EOH

The most recent MOT inspection for this 2004 Toyota Prius passed on 7 November 2025, but the history reveals a concerning trend of significant mechanical failures and recurring advisories. While the vehicle is currently within its test interval, the failure recorded just two days prior in November 2025 highlights serious safety issues, including a fractured offside front coil spring and a dangerous defect regarding the offside front drive shaft bearing housing. The maintenance pattern appears reactive rather than preventative, as evidenced by the frequent failures for lighting, insecure components, and tyre tread depth. The presence of an engine oil leak and a smooth brake pedal in the latest advisory list suggests that while the vehicle is roadworthy, it is entering a phase of increased component degradation that requires close monitoring. With 214,323 miles recorded over 22 years, the vehicle has averaged approximately 9,742 miles per year, which is consistent with typical long-term usage for a hybrid of this era. This mileage level indicates significant wear on high-frequency mechanical components such as the suspension system, drivetrain, and braking assemblies. Given the age and the high mileage, the mechanical integrity of the hybrid battery system and the regenerative braking components should be a primary concern, although the MOT records do not specifically detail the electrical health of the high-voltage system. The consistent usage suggests the vehicle has not been sitting idle for long periods, which helps prevent certain types of seizure, but it does mean that wear-and-tear items are likely nearing the end of their functional lifespans. Prospective buyers must exercise caution regarding the documented history of suspension and drivetrain issues. The previous failure of the offside front coil spring and the dangerous advisory for the drive shaft bearing housing are critical points; during a test drive, you should listen for any rhythmic clicking, clunking, or knocking sounds coming from the front end, particularly when turning the steering wheel or traversing uneven surfaces. Furthermore, the advisory for a smooth brake pedal suggests that the master cylinder or the pedal assembly itself is showing signs of wear, which could lead to a spongy feel or reduced braking effectiveness. You should also inspect the engine bay for any signs of fresh oil seepage to assess the severity of the noted oil leak, as this could lead to more costly repairs if it affects gaskets or seals. Additional attention should be paid to the braking system and lighting. The history of corroded rear brake discs and a corroded nearside rear brake pipe indicates that the vehicle is susceptible to moisture-induced oxidation. Check for any binding calipers or uneven deceleration, and ensure the brake pipes are not excessively scaled or thinning. The recurring advisories regarding headlamp lens clouding suggest the plastic has perished due to UV exposure; while not currently a failure, this will eventually impact night-time visibility. Finally, verify the condition of the tyres, as previous failures for insufficient tread depth suggest that maintenance in this area has been neglected. Check the sidewalls for any signs of perishing or cracking, which is common in vehicles of this age, even if the tread depth remains legal.
