2011 Renault Grand Modus 1.6L Petrol · BL11 LSK

Corrosion across the front suspension and sub‑frame, together with repeated tyre structure failures, defines the mechanical picture of this 2011 Renault Grand Modus. The most recent MOT on 8 October 2025 was passed, but it recorded corrosion on both front MacPherson struts, the front sub‑frame and the rear axle, all noted as “not seriously weakened”. Earlier tests show a pattern of similar corrosion advisories and, more critically, dangerous tyre tears on the front wheels in 2022 and 2023, indicating that tyre integrity has been a recurring concern. At 41 028 miles the vehicle averages roughly 2 700 miles per year, a mileage figure that is low for a fifteen‑year‑old car. Such modest annual accumulation often points to periods of light use or extended storage, which can exacerbate rust formation on chassis and suspension components when the car sits idle. The low mileage does not offset the need to verify that any long‑term parking has not allowed corrosion to progress beyond the advisory stage, nor does it guarantee that wear items such as brakes, bushings or suspension joints have been exercised sufficiently to reveal latent defects. Potential buyers should give particular attention to the front suspension assembly. Inspect the MacPherson strut housings, lower arms and sub‑frame for any signs of surface rust, pitting or compromised welds, and listen for clunking or knocking when driving over bumps, which would suggest that the “not seriously weakened” corrosion has progressed. The shock absorber casings were flagged for external damage in 2024, so check for oil leakage around the mounts and feel for excessive bounce or uneven damping during a road test. Any audible squeak or vibration from the rear trailing arms should also be investigated, as rear suspension arm corrosion was noted in 2020 and 2021. The tyre history demands immediate scrutiny. Dangerous tears were recorded on both front tyres in 2022 and 2023, and advisory notes about sidewall perishing appear in earlier years. Verify that all four tyres are of uniform age, free of cuts, bulges or exposed ply, and confirm that the tread depth meets legal limits. Because brake fluid was described as “slightly contaminated” in 2024 and rear brake imbalance was flagged in 2021, a full brake service is advisable: check for pedal pulsation, uneven braking effort and any fluid leakage from the lines, and consider a fluid replacement and possible re‑adjustment of the rear drums or discs to restore balanced stopping performance.
