2016 Hyundai Ioniq 1.6L Hybrid electric (clean) · LL66 TZP

The most recent MOT test, conducted on 2026-04-07, returned a clean pass, indicating that the vehicle has met all current roadworthiness standards at that time. However, the previous MOT on 2025-08-15 marked a failure due to critical brake system deficiencies, specifically a severely weakened rear brake disc on both sides and brake pads worn below the legal minimum thickness of 1.5 mm. This failure is a stark contrast to the preceding MOTs, which all passed without any recorded defects, suggesting a significant maintenance or usage issue that surfaced during that test. The pattern of passing MOTs followed by a sudden failure highlights the importance of addressing the brake system defects promptly, as they pose a serious safety risk if left unresolved. The vehicle’s recorded mileage of 70,660 miles at the time of this assessment represents a moderate annual usage rate of approximately 7,066 miles per year, which is within the expected range for a 10-year-old car. This level of mileage does not inherently indicate excessive wear, but it does warrant attention to components that are particularly susceptible to cumulative stress, such as the suspension, brake systems, and drivetrain. The absence of rapid mileage accumulation over the past few years suggests that the vehicle has likely been used more conservatively, though prolonged periods of inactivity can still lead to issues like brake pad corrosion, standing corrosion on suspension components, or fluid degradation if not serviced regularly. The gap between the last clean MOT (2024-07-10) and the failure (2025-08-15) is particularly notable, potentially indicating either a delayed response to wear or an underlying issue that became critical only under certain driving conditions. Given the critical brake failures recorded in the 2025 MOT, the prospective buyer must prioritise immediate inspection of the rear brake system. The severely weakened brake discs suggest significant thermal or mechanical damage, which could be exacerbated by uneven wear patterns or binding calipers. On a test drive, listen for any abnormal brake pedal feel—such as sponginess, excessive travel, or a hard pull to one side—indicating potential caliper binding or warped discs. Inspect the rear brake discs for uneven glazing, scoring, or cracks, and check the pads for consistent thickness and signs of glazing or delamination. If the discs are indeed severely weakened, replacement may be necessary, and the buyer should also verify that the rear brake pads are fully renewed to the legal minimum thickness of 1.5 mm. Additionally, check for any fluid leaks around the brake master cylinder or caliper components, as this could signal failing seals or hydraulic system issues. Beyond the brake system, the buyer should conduct a thorough inspection of the vehicle’s suspension and structural integrity, given the potential for prolonged standing or light usage to accelerate corrosion. Pay particular attention to the rear suspension components, including the control arms, bushes, and coil springs, for signs of wear, cracking, or excessive play. Listen for clunking noises during cornering or over bumps, which may indicate worn suspension bushes or damaged springs. The tyre condition should also be scrutinised, particularly for sidewall perishing or cracking, which can weaken the tyre structure over time even with moderate mileage. Given the vehicle’s age, the 12V battery should be tested for voltage output and overall health, as older batteries may struggle under the demands of modern electrical systems. Finally, since the last MOT was over a year ago, the buyer should consider a time-based fluid service, including the engine oil, coolant, and brake fluid, as these fluids degrade with age regardless of mileage. If the vehicle has been stored for extended periods, a thorough inspection of the exhaust emissions system for corrosion or leaks is also advisable, as standing can accelerate rusting in the catalytic converter and muffler components.
