2020 Suzuki Swift SZ3 Dualjet Shvs 1.2L Hybrid electric (clean) · SJ70 AJX

The most recent DVSA examination on 19 August 2026 resulted in a Pass with no defects recorded, however the same date also shows a prior Fail submission containing a cluster of significant tyre and monitoring system defects. Two Dangerous failures were issued, one for the Nearside Front tyre and one for the Offside Front tyre, each citing tread depth below the statutory 1.6 millimetre minimum. A Major failure was additionally recorded against the Tyre Pressure Monitoring System, which was deemed malfunctioning or obviously inoperative. Both rear tyres were also flagged with Advisories for being worn close to the legal limit and worn on the edge. Looking further back, the August 2025 test followed an identical pattern, with a Dangerous failure for the Nearside Front tyre tread depth and an Advisory on the Offside Front tyre. The earlier 2024 examination passed cleanly. The maintenance trend is therefore mixed but overall stable in structural terms, with the dominant concern being a recurring issue with tyre wear rather than any deeper mechanical deterioration. The vehicle appears fundamentally sound but has demonstrated a consistent pattern of premature or uneven tyre wear that warrants close scrutiny. With a recorded reading of 34,966 miles over six years, the vehicle is averaging approximately 5,800 miles per annum, which is notably low for a car of this age. Such low annual usage can reflect gentle short journeys, but it also raises the possibility of extended periods of standing, which carries its own mechanical implications. Brake discs and calipers are susceptible to surface corrosion and binding when a vehicle is left unused, and the cooling system, fuel system, and engine oil can all degrade on a calendar basis rather than purely by mileage. The 1.2 litre Dualjet hybrid powertrain, comprising a mild hybrid SHVS system, is generally robust but should be exercised regularly to keep the 12 volt battery, lithium ion hybrid components, and exhaust emissions system in healthy condition. Despite the low odometer reading, rubber components, fluids, and battery condition should be assessed on a time-served principle rather than mileage alone. Prospective buyers should examine the tyres very carefully, given the recurring pattern of rapid or uneven wear on both front and rear axles across consecutive tests. Edge wear, in particular, may indicate incorrect wheel alignment, worn suspension components, or uneven camber settings. On a test drive, listen for suspension clonks or knocking over bumps, particularly from the front end, and pay attention to any steering pull, vibration through the steering wheel, or uneven braking. Inspect the sidewalls for any cracking, perishing, or bulging, as age-related deterioration can occur even when tread depth appears acceptable. The malfunctioning Tyre Pressure Monitoring System flagged in the latest test should be investigated and rectified, and the buyer should confirm whether the issue has been resolved since the Pass was issued. A four-wheel alignment check is strongly recommended to identify any underlying cause of the repeated premature tyre wear, and all four tyres should ideally be replaced as a matched set to ensure consistent grip and predictable handling. Beyond the tyre concerns, the low mileage context demands attention to areas that deteriorate through age and standing rather than use. The 12 volt battery should be load tested, as low-use vehicles frequently suffer from premature battery failure. Brake calipers and handbrake mechanism should be checked for smooth operation and freedom of movement, looking for any binding, seized sliders, or corrosion on the disc surfaces. Examine the underbody, exhaust system, and suspension components for surface corrosion consistent with a lightly driven but older car. Verify the service history thoroughly, ensuring that oil and filter changes, coolant, brake fluid, and spark plugs have been attended to on a calendar basis even if mileage thresholds have not been reached. The hybrid system warning lights and overall warning lights cluster should be checked at ignition, and a diagnostic scan is advisable to confirm no latent faults exist within the SHVS mild hybrid management system. A careful physical inspection and test drive, combined with a post-purchase alignment and full fluid service, should ensure this Suzuki Swift remains a reliable and economical purchase.
