2016 Hyundai I20 1.0L Petrol · RF66 VCV

The most recent MOT test results reveal a concerning pattern of failure in the 2025-11-10 assessment, where both the near-side and offside front upper anti-roll bar ball joint dust covers failed under the condition that they no longer prevent the ingress of dirt, a critical requirement for protecting the ball joint’s lubrication and integrity. This marks a significant deviation from the vehicle’s previous MOT history, which had consistently passed without defects or advisories over the preceding five years. The failure of both ball joints simultaneously suggests either a design flaw in the dust covers or a deliberate neglect in addressing potential issues, which could indicate either a lack of proactive maintenance or an underlying structural weakness in the suspension assembly. Given that this failure occurred just months after a clean MOT, the buyer should be particularly vigilant about the suspension system’s condition, as this defect could escalate into a major mechanical failure if left unaddressed, potentially compromising steering stability and wheel alignment. The vehicle’s recorded mileage of 69,733 miles for a 2016 Hyundai i20 represents a moderate annual usage rate of approximately 6,973 miles, which is within the expected range for a car of this age and class. However, the absence of significant mileage gaps between MOT tests—particularly the two consecutive clean results in 2023 and 2024—suggests that the vehicle has been in regular use rather than standing idle for extended periods. While lower mileage might imply reduced wear on consumables like brake pads or tyres, the presence of the anti-roll bar ball joint failures indicates that the suspension components have been subjected to more frequent stress, potentially accelerating wear on related bushings, bushings, and seals. The buyer should also consider that the recorded mileage alone does not account for calendar-based degradation, such as the aging of fluids like brake fluid, which can harden and lose effectiveness over time, or the potential for corrosion to develop in components that remain stationary, such as the brake discs or calipers. Given the recent MOT failures related to the front anti-roll bar ball joints, the buyer must prioritise a thorough inspection of the suspension system. On a test drive, listen for unusual clunking or rattling noises from the front of the vehicle, particularly when navigating bumps or sharp turns, as these could indicate loose or worn suspension components. Inspect the front wheels for uneven tyre wear patterns, which may suggest misalignment or suspension issues, and check for any visible oil leaks around the ball joints or adjacent suspension mounts. The buyer should also verify that the steering wheel does not exhibit excessive play or vibration, as these symptoms could signal a failing ball joint or related steering linkage. Immediate attention should be given to replacing the compromised ball joint dust covers and, if necessary, the ball joints themselves, as these are critical for maintaining steering precision and preventing premature wear on the suspension and wheels. Additionally, consider having the suspension components—such as the upper and lower control arms, coil springs, and shock absorbers—inspected for signs of excessive wear or damage, as these can contribute to the observed anti-roll bar failure. For the 2016 Hyundai i20 with its current mileage and maintenance history, the advisories from the 2019 MOT regarding the front tyres being worn close to the legal limit—particularly on the edges—highlight the need for a detailed examination of tyre condition. The buyer should measure the remaining tread depth across the tyre’s central and side regions, as uneven wear can indicate alignment or suspension issues that may have been exacerbated by the recent anti-roll bar failures. Beyond the tyres, the vehicle’s age and usage profile warrant checks for tyre sidewall perishing, which can weaken the tyre structure and increase the risk of blowouts, especially if the tyres have been stored in conditions that accelerate ageing. The buyer should also assess the 12V battery health, as older vehicles of this age are more susceptible to battery failure, particularly if the vehicle has been left stationary for prolonged periods. Test the battery’s voltage when the engine is off and confirm that it holds a charge, and check for signs of corrosion on the battery terminals and cables. Additionally, given the vehicle’s age, it is advisable to verify the service history for time-based fluid servicing, such as the brake fluid, coolant, and transmission fluid, as these fluids degrade over time regardless of mileage. Finally, inspect the exhaust system for leaks or corrosion, which could indicate underlying issues with the catalytic converter or manifold, and ensure that the exhaust emissions system is functioning correctly, as this is a mandatory MOT requirement. If the vehicle has been in regular use, the buyer may also want to check for signs of standing corrosion on the undercarriage, particularly around the wheel arches and under the suspension components, as prolonged exposure to moisture can accelerate rust formation.
