2021 SEAT Arona 1.5L Petrol · RN21 LCV

The SEAT Arona’s most recent MOT history reveals a concerning pattern of repeated failures despite no recorded defects, particularly the back-to-back tests on January 19 and 20, 2026, at exactly 31,149 miles. This suggests either a deliberate retesting strategy or an unresolved issue that repeatedly triggered the tester’s attention, though no specific faults were logged. The previous clean passes in January 2025 and January 2024 indicate the vehicle was otherwise compliant, but the 2026 failures—despite identical mileage—demand scrutiny. The lack of documented defects in failures is unusual; typically, such retests imply a recurring but undiagnosed problem, possibly related to sensor calibration, emissions systems, or minor electrical faults that fluctuate near the pass/fail threshold. The recorded mileage of 31,149 miles over five years aligns with typical usage patterns, averaging around 6,230 miles annually. However, the gap between the 2024 and 2025 tests—spanning roughly 7,837 miles in a year—stands out as unusually high for a vehicle of this age, suggesting either intensive use or extended periods without maintenance. The identical mileage at both 2024 failures (18,385 miles) implies the vehicle was not driven significantly between those tests, which could point to a temporary storage or layup rather than normal operation. This irregularity warrants closer inspection of fluid levels, tyre conditions, and potential neglect-related wear. Given the repeated failures without documented faults, a buyer should prioritise an independent inspection of the vehicle’s emissions system, particularly the DPF or catalytic converter, as these components often trigger retests for minor malfunctions. The binding calipers or uneven brake wear, if present, would explain repeated brake-related concerns, though no such notes appear in the record. Corrosion checks should focus on wheel arches, sills, and suspension mounts, given the vehicle’s age and mileage, while suspension bushes and coil springs should be assessed for excessive play or cracking. The 2026 retests also hint at potential electrical gremlins—such as faulty sensors or wiring—that could affect braking, steering, or emissions systems. A thorough diagnostic scan would be advisable to uncover any hidden issues.
