2016 Lexus IS 2.5L Hybrid electric (clean) · MS07 AFC

A clean five-year run of MOT passes with no failures paints the picture of a mechanically well-maintained Lexus IS, yet the two advisories logged on the rear braking system in consecutive late-summer tests form the only meaningful thread of concern in the history. The 2026-08-25 pass noted an offside rear brake disc worn, pitted or scored but not seriously weakened, following on from a 2025-08-26 advisory for an offside rear brake pipe corroded and covered in grease or other material. The intervening years of 2022, 2023 and 2024 all recorded no advisories at all, so this is not a pattern of chronic deterioration but rather a localised rear-corner issue that has surfaced as the car has moved into its tenth year. The trend is broadly stable from a roadworthiness perspective, with the only forward watchpoint being whether the pitted rear disc is approaching its minimum thickness and whether that concealed corrosion on the brake pipe has continued to develop unseen behind its coating of grease. Against a ten-year vehicle age, the recorded 47,577 miles equates to roughly 4,758 miles per year, which is comfortably below the average for a car of this type and points to predominantly light or short-journey use. The MOT record shows consistent annual testing with no gaps, suggesting the vehicle has not been laid up off the road for extended periods, which removes the usual concerns around seized brakes, perished hoses or stale fluids that come with multi-year storage. Mechanically, this lower accumulation is generally favourable for the major drivetrain and interior components, though it does mean the consumable items such as brake discs, pads and tyres may have aged through corrosion and surface degradation rather than being worn away through friction, which is consistent with the pitted rear disc advisory just recorded. Buyers should be aware that low annual mileage can occasionally mask underlying issues if short trips have prevented components from reaching full operating temperature, so a thorough warm-up check remains sensible. With the rear brake pipe and offside rear disc specifically flagged, the inspection should focus on this corner of the car. On a test drive, listen for any scraping, grinding or metallic rubbing from the offside rear as the wheel rotates, which would indicate the pitted disc has now dropped below serviceable thickness or that a caliper is binding and causing uneven pad wear. Apply the brakes firmly several times from moderate speed and feel for any rear-end judder, vibration through the pedal or pulling to one side, all of which would suggest the disc lip has grown or the disc has become warped through uneven corrosion. With the brake pipe advisory in mind, the offside rear pipework and its unions should be visually examined for any fresh corrosion seepage, crusting or weeping of brake fluid, particularly along the underside where road salt and moisture collect, and the flexible rubber section of the rear brake hose should be checked for cracking or bulging. A firm pedal with good bite and no warning lights on the dashboard will confirm the hydraulic system is currently sound. Beyond the documented rear braking items, the rest of the recorded history gives little cause for concern, but a prospective buyer should still carry out a structured physical inspection appropriate to a ten-year-old executive saloon. Check the coil springs and suspension bushes for any sagging, cracking or splitting, as these are common advisory areas on cars of this age even when not yet flagged. Inspect the exhaust system for corrosion at the joints, hangers and heat shields, and confirm the underbody and subframe mounting areas are free from significant structural corrosion, particularly given the brake pipe corrosion noted on the offside rear. On the test drive, listen for any clonks or knocks from the front suspension over speed humps and uneven surfaces, feel for vagueness or wandering in the steering, and confirm the automatic or manual transmission changes cleanly without flare, shudder or delayed engagement. Finally, verify that all dashboard warning lamps extinguish promptly after start-up, that the air conditioning blows cold, and that the infotainment and driver assistance systems function as expected, giving a complete picture of a low-mileage, well-kept Lexus IS whose only immediate mechanical watchpoint is the rear braking system.
