2012 Suzuki Swift 1.2L Petrol · LO12 AAV

The most recent MOT test for this Suzuki Swift was conducted on 2025-10-17 and resulted in a failure, with the primary defect being an excessively worn offside front suspension arm pin or bush, classified under 5.3.4(a)(i). This marks a significant deviation from the vehicle’s previous MOT history, where all tests from 2022 to 2024 passed without defects or only minor advisories, such as a non-obligatory mirror damage and a near-side steering rack joint play advisory. The failure suggests a critical mechanical issue has developed, likely due to prolonged wear or a failure to address earlier advisories, particularly the steering rack joint play, which could have contributed to excessive movement in the suspension arm components. While the prior tests indicated no urgent roadworthiness concerns, the current failure underscores the need for immediate attention to the suspension system, as worn suspension arm bushes can lead to further structural damage, misalignment, and compromised handling stability. The vehicle’s recorded mileage of 102,573 miles at the age of approximately 14 years represents a moderate annual usage rate of around 7,327 miles per year, which is within the expected range for a car of this age and model. However, the consistent mileage accumulation over the past decade suggests the vehicle has been in regular use, which can accelerate wear on critical components such as the suspension, brakes, and drivetrain. The absence of significant mileage gaps could imply that the car has not been left standing for extended periods, potentially exacerbating issues like brake disc corrosion or caliper binding, or allowing fluids to degrade from stagnation. Additionally, the steady mileage accumulation may have contributed to the progression of the suspension arm bush failure, as continuous loading and movement can accelerate bush wear, particularly in a suspension system that has not been serviced or inspected at appropriate intervals. Given the recent MOT failure and the critical nature of the offside front suspension arm pin or bush issue, the prospective buyer should prioritise a thorough inspection of the suspension system. The worn bush will require immediate replacement, as further deterioration could lead to misalignment, uneven tyre wear, and potential steering instability. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when navigating bumps or cornering sharply, as these could indicate additional wear or damage to suspension components. Additionally, check for uneven tyre wear patterns, which may suggest misalignment caused by the faulty suspension arm. Beyond the suspension, inspect the steering system for excessive play or binding, as the earlier steering rack joint play advisory may have contributed to the current failure. Ensure the brakes are functioning correctly by testing pedal feel and listening for grinding or squealing noises, which could indicate worn brake pads or warped discs. For the Suzuki Swift’s age and mileage, the buyer should also conduct a comprehensive physical inspection of the vehicle’s structural and fluid-based components. Given the vehicle’s age, examine the tyres for signs of sidewall cracking or perishing, which can compromise their integrity and safety, especially with the increased risk of road debris or potholes. Check the 12V battery for signs of corrosion on terminals or a weak hold-up current, as older batteries may struggle to maintain power, particularly in cold weather or during prolonged standing. Inspect the engine bay and undercarriage for signs of oil leaks, particularly around the valve cover, oil filter housing, and transmission, as these can indicate failing seals or gaskets that may need replacement. Additionally, consider verifying the service history for fluid servicing, particularly the brake fluid, coolant, and transmission fluid, as these fluids degrade over time and should be replaced at recommended intervals to prevent corrosion and mechanical failure. Finally, address the non-obligatory mirror damage and any remaining steering rack joint play, as these advisories may have been overlooked but could contribute to long-term wear or safety concerns if ignored.
