2015 Toyota Auris 1.8L Hybrid electric · SC15 LFS

This Toyota Auris has passed its most recent MOT in March 2026, but the history reveals a persistent and worsening pattern of corrosion in the rear suspension and chassis components. While the mileage of 97,300 is roughly typical for an 11-year-old vehicle, the mechanical condition is trending downwards. The primary risk is significant structural and suspension corrosion. Since 2024, the MOT records consistently highlight corrosion on the rear sub-frame, suspension arms, and coil springs. Although these were noted as "not seriously weakened" in previous years, the most recent inspection shows the issue is spreading, with shock absorber casings now showing external corrosion alongside the existing sub-frame and arm issues. The vehicle's maintenance trend appears to be reactive rather than preventative. The failure in March 2026 was caused by a combination of worn tyres, binding brakes, and lighting issues, alongside the recurring corrosion. While the immediate safety failures like the tyres and brake pads seem to have been addressed for the pass, the underlying issue of progressive rust is clearly escalating. The mileage suggests the car has been used regularly, which is generally positive for preventing seized components, but it has not prevented the buildup of corrosion. This suggests the vehicle may have been exposed to harsh road conditions, such as salted winter roads, which is accelerating the decay of the underbody.
