2016 Lexus IS 2.5L Hybrid electric (clean) · BU16 AAV

The defining mechanical story of this 2016 Lexus IS is the abrupt appearance of rear-tyre condition advisories at the most recent test on 7 January 2026, following four consecutive clean passes with no defects recorded between March 2022 and January 2025. While the vehicle remains roadworthy and the advisory items are not failure-level defects, four rear-axle tyre advisories on a single test represents a notable pattern of uneven or accelerated rear-tyre wear, which warrants specific inspection attention on a viewing. The historical stability of the record is otherwise strong, with no failed tests recorded across the five DVSA examinations provided, but the sudden emergence of wear-related advisories on both rear tyres simultaneously is consistent with an underlying alignment, suspension, or brake-related issue rather than coincidental tyre ageing. With a recorded odometer reading of 298,577 miles spread across roughly ten years, this Lexus IS has covered approximately 29,858 miles annually, a figure significantly above the typical UK average and placing considerable accumulated stress on consumable components, suspension geometry, and drivetrain hardware. There are no apparent testing gaps in the recorded history, with annual examinations consistently present, suggesting continuous use rather than periods of standing, which is generally favourable for preventing moisture-related corrosion in the braking system and exhaust components. However, high-mileage IS models commonly exhibit accelerated wear on rear suspension bushes, coil springs, and the rear thrust arms, and the chassis has already demonstrated rear-axle component behaviour that has prompted tyre-wear advisories, indicating that this area demands particularly close physical scrutiny at the point of inspection. For a prospective buyer, the immediate priority is to investigate the cause of the dual rear-tyre wear pattern, as tyres wearing simultaneously on both inner and outer edges on the same axle typically points to a mechanical root cause rather than normal rotation. On a test drive, listen for clonking or knocking noises from the rear suspension over uneven surfaces, which would indicate worn bushes or top-mount failure, and pay close attention to any rear-end instability or wandering behaviour under braking or during lane changes. Inspect the rear brake calipers for binding, as seized caliper slides are a known issue on high-mileage Lexus vehicles and produce exactly the type of uneven, edge-localised tyre wear recorded here. Uneven tyre shoulder wear can also be symptomatic of rear thrust-arm or trailing-arm bush degradation, so a borescope inspection of the rear subframe mounting points and a physical check for free play in the rear suspension linkages by a competent technician is strongly advisable. Beyond the suspension and braking systems, the high overall mileage dictates that drivetrain components should be examined with appropriate rigour. Request evidence of transmission fluid changes on the automatic gearbox, as Lexus torque-converter units are generally durable but do require periodic fluid renewal at this odometer reading to maintain reliability. Listen for any whining or bearing-type noises from the rear differential area, and check for oil seepage at the engine sump, cam covers, and the rear main seal. A compression or leak-down test would provide valuable confirmation of internal engine condition given the mileage, while a thorough underside inspection on a ramp should look for corrosion on brake lines, exhaust mounting points, and any structural sections given the vehicle's age. Finally, verify that the tyre size and brand match across the rear axle, as mixing compounds or dimensions can itself produce the uneven wear pattern observed in the MOT record, and confirm that any replacements are of the correct load and speed rating specified by Lexus for this model.
