2021 Suzuki Swift SZ-L Dualjet Mhev 1.2L Hybrid electric (clean) · ST71 AAY

The latest MOT test conducted on 22 September 2025 resulted in a pass, indicating that the vehicle remains legally roadworthy. However, the maintenance trend shows a persistent issue regarding the condition of the tyres, with advisories for perishing and cracking appearing in both the 2024 and 2025 tests. While the vehicle has avoided major mechanical failures or structural corrosion, the recurrence of these advisories suggests a reactive rather than proactive approach to consumable replacement, as the tyre degradation has been noted for two consecutive years without being fully rectified. The recorded mileage of 21,615 miles over approximately five years is notably low, averaging roughly 4,323 miles per year. While this suggests minimal wear on the drivetrain, engine internals, and suspension bushings, such low usage often indicates a profile of short urban journeys or extended periods of standing. Mechanically, this can be more detrimental than consistent motorway mileage, as it increases the likelihood of carbon build-up in the engine and the degradation of rubber components due to lack of regular flexion and heat cycles. The primary area of concern for a prospective buyer is the documented perishing of the tyres. This is a chemical breakdown of the rubber compound caused by age and UV exposure rather than physical wear. You must closely inspect the sidewalls and the tread grooves of all four tyres for fine hairline cracks. During a test drive, be alert for any unusual road noise or vibrations, although perishing is primarily a structural risk that can lead to sudden failure. Given that the front tyres were flagged as cracking in both 2024 and 2025, a complete replacement of the tyre set is strongly advised to ensure safety, regardless of the remaining tread depth. Due to the low annual mileage, further attention must be paid to components affected by inactivity. Inspect the brake discs for heavy surface corrosion or pitting, and feel the wheels after a test drive to ensure no binding calipers are causing excessive heat. The auxiliary 12V battery should be tested for health, as infrequent charging cycles can lead to premature failure. Finally, verify the service records to confirm that engine oil and filters have been changed according to the manufacturer's time intervals rather than mileage, as oil degrades over time and can lead to sludge formation if left unchanged for several years.
