2018 Suzuki Ignis 1.2L Petrol · CU18 SWW

The 2018 Suzuki Ignis presents a mixed roadworthiness picture marked by recurring mechanical advisories that persist across multiple MOT cycles rather than appearing as isolated incidents. Starting with the 2021 failed test involving misaligned headlights and worn tyres, the vehicle returned to a clean record in 2022 before encountering a series of corrosion-related and wear-related findings in 2023 and 2024. The 2025 tests revealed fresh corroded subframes on both front and rear ends alongside a corroded offside front suspension arm, while also noting persistent brake wear on the nearside front disc and thinning of outer front brake pads. Despite these ongoing issues, the car managed to pass three successive MOTs between January 2024 and December 2025, indicating that the current condition does not represent an immediate safety crisis but rather a vehicle with documented structural and component degradation that requires careful attention. The recorded odometer reading of 23,187 miles on a model from 2018 yields an average annual accumulation of approximately 2,900 miles, which is substantially lower than typical usage patterns for a vehicle of this age. This low mileage could reflect extended periods of infrequent use or prolonged storage, yet the absence of dramatic mileage spikes between the 2021 and 2025 failures suggests that the vehicle was not subjected to sudden heavy load or frequent driving that might accelerate component wear. The gap between the 2021 failed test and the first successful return in late 2025 indicates a period where no new defects were identified, but the persistence of corrosion on critical structural members implies that the vehicle may have been stored under conditions that allowed rust to develop undetected, potentially compromising long-term structural integrity even if the active drivability remains acceptable. The subframe corrosion flagged in 2025—affecting both front and rear sections under advisory 5.3.3 (b) (i)—requires particular scrutiny as compromised subframes can alter wheel alignment and affect suspension geometry, leading to increased wear on other components such as bushings and control arms. The offside front suspension arm corrosion similarly threatens lateral stability and handling precision, especially when combined with the steering rack inner joint play noted in 2025, which may manifest as vague steering feedback or increased body roll at speed. Brake system health appears degraded given the consistently thin outer front brake pads and worn nearside front discs since 2021, necessitating verification of rotor condition and pad material integrity during a test drive to confirm whether replacement is imminent or if deeper caliper or line issues exist. Additionally, the repeated tyre wear warnings from 2021 point toward either uneven loading or lack of regular rotation, which could exacerbate existing suspension wear if left unaddressed. For a prospective buyer, a systematic test drive should prioritise visual inspection of the subframe welds and floor pan for any signs of pitting, flaking rust, or metal spalling that might indicate deeper corrosion progression. The front and rear suspension arms should be examined for visible wear, looseness when moved manually, or signs of broken bushings that could cause play under load. Brake performance demands close observation of pedal feel, pedal travel distance, and audible noises during deceleration; particularly on the nearside front, the combination of thin pads and worn discs warrants checking for squeal, grinding, or pulsating behaviour. Steering responsiveness should be tested at various speeds to detect any binding or vague feedback stemming from the offside front suspension arm issue. Finally, given the history of tyres being worn close to legal limits, a full tread depth measurement and visual inspection for sidewall cracks or uneven wear patterns will help determine whether the tyres require immediate replacement or if alignment adjustments are needed to restore proper contact patch distribution.
