2015 Vauxhall Corsa 1.2L Petrol · ST65 FMM

A clear structural corrosion concern sits at the centre of this Vauxhall Corsa's recent roadworthiness record, with a near-side front sub-frame that has progressively deteriorated across three consecutive tests before culminating in a Major failure on 17 March 2026 when excessive corrosion at the wishbone mounting was deemed to seriously weaken the component. The car was returned for a re-test just two days later on 19 March 2026 and passed, indicating the sub-frame was either repaired, treated, or replaced in that brief window, though no advisory was recorded on the pass to confirm the remedial work carried out. That same March 2026 visit also flagged a fractured off-side front coil spring and a split off-side front outer CV joint boot, both of which were attended to before the re-test as no corresponding advisories appear on the pass certificate. Earlier records show the sub-frame corrosion was first noted as a minor advisory in October 2023 with general surface corrosion across the structure, then absent from the December 2024 test, suggesting either a period where no significant progression was visible or perhaps surface treatment undertaken at that point. The combined picture is one of a chassis component that has been gradually degrading rather than suffering a sudden failure, which is a pattern worth taking seriously. At 57,806 recorded miles across eleven years, this Corsa has covered approximately 5,255 miles annually, which is notably below average for a vehicle of this age and type and points toward either light general use or extended periods of inactivity. The MOT testing pattern is fairly regular at annual intervals, with no multi-year lay-up gaps that might have masked deterioration, and the mileage progression between tests appears broadly consistent with the annualised figure rather than showing any sudden spikes that would suggest heavy motorway use. Mechanically, this lower accumulation rate means the engine, transmission, and clutch assemblies are likely to be in relatively good condition with limited wear on internal components, while brake discs and pads, along with clutch material, will almost certainly have substantial remaining service life. The downside of such modest usage on a car now passing into its twelfth year is the increased likelihood of corrosion taking hold on undersealed components, seized brake calipers from infrequent operation, and perishing rubber bushes and boots, all of which align with the defects observed in the MOT record. For a prospective buyer, the immediate priority must be a thorough physical inspection of the front sub-frame, both sides, with particular attention to the near-side wishbone mounting area where the Major failure was recorded. Any evidence of fresh welding, patching, or replacement sections should be questioned, and the component should be inspected for residual bubbling, flaking, or perforation around all mounting points, not just the area previously flagged, as corrosion of this nature rarely remains isolated. A ramp or undertrine examination is strongly advisable, and the repair history from the March 2026 test should be verified with documentation or a V5C check to confirm what work was actually completed. Beyond the sub-frame, the fractured off-side front coil spring that was replaced indicates the suspension should be tested on road for any continued signs of instability, knocking over uneven surfaces, or uneven ride height, while the replaced CV boot on the same side warrants listening for any clicking or clonking during full-lock manoeuvres which would suggest joint damage had already occurred before the boot failure was rectified. On a test drive, particular attention should be paid to steering precision and any vagueness around the straight-ahead position, as a compromised sub-frame mounting can introduce geometry changes that manifest as steering pull to one side, uneven tyre wear, or a feeling of looseness through the wheel. Listen for any clonking or creaking from the front suspension over speed bumps and potholes, which could indicate deteriorated bushes or the early stages of further structural movement at the repaired mounting. Inspect the nearside front tyre closely for any signs of uneven shoulder wear, as the March 2026 advisory noted edge wear on that corner which, given the sub-frame failure, may have been a symptom of misalignment rather than simply a worn tyre. Finally, with the car having stood for periods given its low mileage, the brakes should be checked for smooth operation without any juddering or pulling, the handbrake holding firmly on an incline, and the engine started from cold to observe for any smoke, hesitation, or irregular idle that might indicate issues from infrequent use.
