2021 SEAT Arona 1.0L Petrol · HA11 LGH

The 2021 SEAT ARONA presents a mechanical profile dominated by a persistent rear brake system concern coupled with recurring front brake wear, while rear tyres exhibit consistent damage to the outer edges. Between the 2026-03-24 failure and the 2026-03-25 pass, the vehicle experienced two separate MOT assessments, with the first failing due to dangerously weakened rear brake discs alongside front brake disc deterioration and cracked rear tyres, and the second passing once the rear brake condition improved. This pattern indicates the rear brake assembly has suffered progressive degradation that required intervention, whereas the front brake wear appears to have stabilised to a mildly worn state by mid-March 2026. The rear tyre cracking has also remained evident since the 2025-03-25 passing, suggesting ongoing exposure or continued deterioration despite the interim passing result. With 56,046 recorded miles on a model that is approximately five years old, the average annual accumulation sits around 11,200 miles per year, which falls within the expected range for its age class and does not suggest abnormal acceleration in usage. The single-month interval between the January 2026 pre-failure test and the February 2026 failure attempt implies the rear brake issue was either intermittently present or became critical enough to trigger a fail just before resolution. The subsequent successful March 2026 test following the March 24 failure suggests the brake problem was addressed or reduced sufficiently to meet MOT criteria, though the lack of intermediate testing between early and late March leaves some uncertainty about whether the rear brake condition fluctuated significantly throughout that period. The most critical areas requiring attention during a test drive are the rear brake discs and the front lower suspension linkage. The rear brake disc weakness flagged in both the 2026-03-24 and 2025-03-25 tests warrants visual confirmation of pad thickness, rotor surface condition, and any signs of heat distortion or uneven wear; a juddering or spongy brake pedal response when applying pressure to the rear wheels would indicate the discs remain compromised. Similarly, the front lower suspension arm and bush were identified as excessively worn in the 2026-03-24 failure, so the driver should monitor for any clunking or skipping over bumps, particularly when the vehicle encounters speed bumps or uneven pavement, and note whether the steering feels loose or vague through the lower control arm movement. These symptoms, when observed during a dynamic test drive, will confirm whether the recorded advisory flags translate into tangible handling or braking deficiencies that could affect safety.
