2013 Lexus IS 2.5L Hybrid electric (clean) · FN63 CKF

The most recent MOT in August 2025 was a pass, but it followed a failure only days earlier due to severely corroded brake pipes on both front and rear axles. Even after repairs, that pass still lists multiple advisories for brake pipe corrosion on all four corners and a brake disc wear issue, meaning the braking system remains an area of concern. Recurring brake pipe corrosion has been noted in every MOT since 2022, progressing from general advisories to a major failure by mid-2025. This pattern suggests the underbody brake lines are prone to rust and may need ongoing attention or eventual replacement. The fact that a failure for excessive corrosion occurred so recently indicates the problem became acute despite previous warnings. The trend is worsening: earlier inspections only flagged corrosion as an advisory, but the 2025 failure showed it had reached a point of being immediately dangerous. While the car passed after work, the persistent repeat advisories imply the underlying issue is not permanently resolved and could return again quickly. The mileage of about 108,857 miles over 13 years is roughly 8,374 per year, which is typical for a vehicle of this age. There is no strong signal of hard use or long-term standing; the mileage pattern is consistent with normal daily driving. However, the corrosion pattern suggests the car may have been exposed to damp or road salt conditions rather than being notably over- or under-used.
