2021 Hyundai Ioniq Electricity · 14 LAN

The most recent MOT test on 2026-04-02 returned a clean pass, indicating that the vehicle has met all roadworthiness standards at that time. However, the prior MOT history reveals a concerning pattern of recurring issues, particularly with the electronic parking brake system, which failed in 2025-03-24 with a major defect—specifically, an inability to operate the parking brake satisfactorily. This failure was accompanied by a dangerous advisory regarding the parking brake efficiency, which fell below 50% of the required value, posing a significant safety risk. While the vehicle passed subsequent tests in 2025-03-25 and 2024-01-31, the presence of these repeated advisories and the severity of the parking brake issue suggest that either the problem has not been fully resolved or that there may be underlying wear or electrical faults affecting the system’s reliability. Prospective buyers should be highly cautious, as this defect could lead to further complications if not addressed promptly, potentially compromising the vehicle’s ability to hold a parking brake securely, especially in adverse conditions. The recorded mileage of 46,923 miles for a 2021 Hyundai Ioniq represents a reasonable annual usage rate of approximately 9,385 miles per year, which is typical for a vehicle of this age and class. This level of mileage does not indicate excessive wear beyond what is expected for a well-maintained car over five years, but it also does not suggest unusually light usage either. The absence of significant mileage gaps suggests consistent driving habits, though prolonged periods of inactivity could still contribute to minor issues such as condensation in the fuel system, battery drain from residual electrical activity, or minor corrosion at joints or seals. However, the primary concern remains the electronic parking brake system, which may have been subjected to wear or electrical fatigue over time, particularly if the vehicle has been used in varied driving conditions or exposed to extreme temperatures. The fact that this issue persisted through multiple MOTs underscores the need for thorough investigation into its cause and resolution before proceeding with purchase. Given the recurring MOT failures related to the parking brake system, the buyer should conduct a meticulous inspection of the vehicle’s braking and electrical components. On a test drive, listen for any unusual noises from the parking brake mechanism, such as grinding, squeaking, or resistance when engaging or releasing the brake pedal. Check for excessive pedal travel or sponginess, which could indicate a failing hydraulic system or electrical malfunction. Visually inspect the parking brake cables and rods for signs of wear, corrosion, or misalignment, and ensure the caliper or disc assembly is not binding or seized. Additionally, verify that the parking brake is fully released when the vehicle is stationary, as a defective system could fail to secure the wheels properly, leading to unintended movement or rollaway risks. If the issue persists, consider having a qualified technician perform a diagnostic check of the electronic parking brake controller and sensors, as well as a full inspection of the hydraulic or mechanical parking brake components. For the buyer’s own safety and to mitigate future risks, it is advisable to address the parking brake defect immediately, even if the vehicle has passed subsequent MOTs. If the issue cannot be resolved, the vehicle may not be roadworthy until the problem is rectified, and the buyer should consider whether the cost of repairs justifies the purchase. In the interim, the buyer should also perform a comprehensive physical inspection of the vehicle, focusing on areas prone to wear or failure at this mileage level. Check the front tyres for signs of uneven wear, particularly around the shoulder areas, which could indicate alignment or suspension issues. Inspect the suspension components, including coil springs, shock absorbers, and suspension bushes, for signs of excessive play, leaks, or physical damage, as these can lead to handling problems and reduced ride comfort. Additionally, examine the exhaust system for leaks or corrosion, ensuring there are no restrictions that could affect emissions or engine performance. Finally, verify the condition of the 12-volt battery and associated wiring, as prolonged inactivity or electrical drain can lead to failure, and check for any visible signs of fluid leaks under the vehicle, such as coolant or oil, which could indicate failing seals or gaskets. If the vehicle has been stored for extended periods, it may also benefit from a thorough check of the fuel system for moisture or sediment buildup, as well as a review of the service history to confirm that time-based maintenance, such as fluid changes, has been completed.
