2005 Lexus IS250 2.5L Petrol · HG55 LXF

The latest MOT test in November 2025 initially failed due to an inoperative or malfunctioning engine management warning light, but it passed after rectification, with advisories for a minor front exhaust leak and worn, pitted, or scored brake discs on both axles. The broader trend shows a largely stable maintenance history, with only minor advisories in recent years, suggesting the vehicle has been kept in reasonable mechanical order. However, the recurrence of brake disc wear and the exhaust leak indicate areas requiring attention, while the recent MIL failure highlights the need to verify the underlying cause was properly resolved. At 139,837 miles over 21 years, the annual mileage of approximately 6,659 miles is typical for a vehicle of this age, indicating consistent rather than excessive or negligible use. This usage pattern suggests moderate wear on consumables and suspension components, but not the extreme fatigue associated with very high mileage. The lack of prolonged standing is positive, as it reduces risks of corrosion, fluid degradation, or seized components that often affect low-mileage examples. The advisories for worn and pitted brake discs front and rear should be investigated closely, as these can lead to reduced braking efficiency, judder through the pedal, or uneven pad wear. On a test drive, listen for grinding or squealing under braking and check for vibration through the steering wheel or pedal, which may indicate warped discs. The minor exhaust leak, likely from a joint or gasket, may produce a faint hissing or ticking noise from the engine bay and could worsen over time, affecting emissions and cabin comfort. Additionally, the 2022 advisories for tyre cracking and edge wear, along with a binding rear brake, suggest the braking system and tyres have a history of wear—inspect the current tyres for perishing, uneven tread, and ensure the rear calipers are not dragging, which can cause overheating and premature disc wear. Given the vehicle’s age, also assess the condition of suspension bushes, coil springs, and shock absorbers for signs of deterioration, such as clunks over rough surfaces or excessive body roll. Check the 12V battery health, as older batteries are prone to failure, and verify service records for timely fluid changes, particularly transmission and differential oils, which degrade with time as much as mileage. Finally, examine the underbody and wheel arches for corrosion, as rust can compromise structural integrity, especially in a car of this vintage.
