2004 Toyota Prius 1.5L Electric · BW04 AEX

The vehicle is currently roadworthy but the maintenance history reveals a reactive service pattern rather than proactive care. While the most recent test in October 2025 at 166,651 miles resulted in a pass, it followed a significant failure involving multiple critical mechanical defects. The trend shows an intermittent history where faults are only brought up to standard after failing an inspection, suggesting that the previous owner only addressed components once they reached the point of legal failure. At 166,651 miles, this 22-year-old Prius has averaged approximately 7,575 miles per year, which is consistent with typical annual usage for its age. However, the data shows a period of high activity between September 2024 and October 2025, where the car covered 4,784 miles in just thirteen months. This rapid accumulation, combined with the multiple failures in September 2024 at the 161,000-mile mark, indicates that the vehicle is experiencing significant stress on its wear components despite the relatively low annual mileage. A buyer must pay close attention to the front and rear suspension, as the record flags a history of failing components. The tester identified a fractured nearside rear coil spring, worn nearside front suspension arm ball joints, and damaged anti-roll bars in late 2024. By the 2025 test, the nearside front lower suspension arm bush showed signs of wear. These recurring issues suggest that the suspension geometry is reaching the end of its functional life and requires a thorough physical inspection for further play or rust-related degradation. The braking system also shows clear signs of neglect. In September 2024, both rear brake pads were below the legal limit and the parking brake efficiency failed to meet requirements. The October 2025 test noted that both front and rear brake discs were pitted and scored. The repeated failure of the Malfunction Indicator Lamp (MIL) in two consecutive years is also a concern, requiring a professional diagnostic scan to ensure there are no hidden engine faults or sensor failures that were cleared simply to pass the MOT.
