2009 Toyota Yaris 1.3L Petrol · GL09 OYO

A clear pattern of corrosion-related advisories dominates the MOT record for this 59,880-mile 2009 Toyota Yaris, with brake hoses, brake ferrules, brake pipes and chassis components all flagged over successive tests. The most recent examination on 24 June 2026 recorded five advisories, four relating to slight corrosion on the front and rear brake hose ferrules and one noting the offside front brake pipe corroded and covered in grease or other material; the same five items appear on a failure test taken on the identical date, suggesting a retest scenario rather than a straightforward mechanical defect. Looking back further, the 2025 test introduced a structural advisory concerning nearside rear chassis corrosion within 30cm of a mounting, while the 2024 test added advisories for binding offside front brake, nearside rear tyre wear and damage, and an observation that the underside of the vehicle was starting to rust. A headlamp aim failure on the nearside side in 2024 was the only formal fail item across the visible history. The overall trend is one of progressive underbody and brake-line deterioration rather than any acute mechanical crisis. The recorded mileage of 59,880 across approximately seventeen years equates to a yearly average of around 3,500 miles, which is well below typical usage figures for a car of this age. No extended testing gaps appear in the supplied history, with annual examinations recorded through to June 2026, indicating the vehicle has remained in continuous use rather than being laid up. Low annual mileage of this nature means wear on major drivetrain components, clutch and high-mileage service items is likely to be modest, but it does not protect the underbody, brake lines, hoses and ferrous components from oxidation. The recurring corrosion advisories on a comparatively low-mileage vehicle underline this point: oxidation on brake hoses, ferrules, pipes and chassis members is driven by environmental exposure, road salt and moisture rather than distance travelled, which is why these advisories are appearing despite the modest odometer reading. For a prospective buyer, the underbody corrosion theme should be the primary inspection focus. The 2025 advisory specifically flagged nearside rear chassis corrosion within 30cm of a mounting point, so close visual examination of the rear structural sections, suspension turrets, mounting points and any inner box sections accessible through access holes or with a torch is essential, looking for perforation rather than just surface scaling. The brake hose and pipe advisories across 2025 and 2026 should prompt a thorough check of all four flexible hoses, the offside front rigid brake line where it runs along the chassis or subframe, and the condition of any protective grease already applied, as covering corroded brake pipes in grease is a recognised short-term cosmetic fix that can mask active rusting. On a test drive, listen for any scraping or knocking from the rear suspension over bumps, which could indicate compromised mounting points, and apply the brakes firmly from speed to feel for pull, judder or a soft pedal that might suggest a binding caliper or weakened flexible hose. The 2024 advisories for offside front brake binding and nearside rear tyre wear and damage are also worth chasing down, as a binding caliper that was only advisory at the last recorded test could have progressed. On a road test, feel for the offside front wheel running hotter than the others after a steady drive, any pulling to one side under braking, or uneven pad wear visible through the wheel. Inspect the nearside rear tyre for inner-edge wear, cracking and perishing, and check the offside front headlamp alignment, as the 2024 failure for offside headlamp aim too low could recur if the mounting or adjustment has shifted. Finally, given the low annual mileage, confirm that the vehicle has been exercised regularly enough to keep the catalytic converter, exhaust system and rear brakes free from internal corrosion, and verify that the most recent brake hose and pipe advisories have either been properly repaired or are being actively monitored, as items currently classed as advisories will eventually cross into fail territory if left unaddressed.
