2023 Ford Mustang Mach-E EXT Range AWD Electric · JC60 AMC

The most recent MOT test on 2026-06-30 resulted in a passing outcome, marking a significant improvement from the previous test on 2026-06-24, which recorded multiple major defects related to the offside rear lighting system. The failure highlighted a persistent issue with multiple light sources—specifically the offside rear inner position, stop, and direction indicator lamps—being non-functional, which is a critical safety requirement. This suggests a recurring problem with either the wiring harness, bulb sockets, or the electrical control module responsible for these circuits. While the current MOT clears these concerns, the history indicates that the vehicle’s lighting system may have been prone to intermittent or persistent electrical faults, warranting careful attention to any recurring issues in future servicing. The fact that the vehicle passed the latest test implies either a repair was completed satisfactorily or the underlying cause has been addressed, but buyers should remain vigilant about potential secondary damage or residual electrical stress in the affected wiring. The recorded mileage of 17,446 miles for a 2023 Ford Mustang Mach-E represents a relatively low annual usage rate of approximately 5,815 miles per year, which is notably below the industry average for vehicles of this age and class. Such low mileage can stem from either light daily use, long periods of inactivity, or strategic driving patterns that minimise wear. However, prolonged standing—especially in a vehicle with electric drivetrain components—can lead to specific issues. For example, battery health may degrade if the vehicle is left unused for extended periods without a proper charge cycle, potentially causing reduced range or charging efficiency. Additionally, standing in damp or corrosive environments can accelerate rust formation in structural components, particularly around wheel arches, undercarriage, and within the cabin, where condensation may accumulate. The suspension and braking systems, while not directly affected by mileage, could also show signs of wear from infrequent use, such as stiffening of suspension bushes or potential binding in brake calipers due to lack of movement. Given the vehicle’s low-mileage profile and the clean MOT history aside from the resolved lighting faults, prospective buyers should conduct a thorough physical inspection to address both age-related and usage-specific concerns. First and foremost, examine the tyres for signs of sidewall perishing or cracking, which can occur even at low mileage if the vehicle has been stored without proper care. Check the tread depth uniformly across all four tyres and inspect the sidewalls for any visible cracks or delamination, as these can compromise structural integrity and lead to sudden failure. Next, verify the battery’s condition, ensuring it holds a charge when tested and that there are no signs of corrosion on the terminals or cables. Given the electric drivetrain, the high-voltage battery system may require periodic checks for thermal degradation or software updates, though this is typically handled by the manufacturer rather than the buyer. For the suspension and braking systems, despite the low mileage, buyers should listen for unusual noises during a test drive, such as clunks or rattles from the rear suspension, which could indicate worn or damaged suspension bushes, broken coil springs, or loose mounting points. Inspect the brake discs and pads for signs of uneven wear, corrosion, or binding, particularly if the vehicle has been stationary for extended periods, as this can lead to seized calipers or warped discs. The exhaust system should be checked for leaks or excessive backpressure, which could signal catalytic converter or manifold issues, though the Mach-E’s electric exhaust is less prone to wear than a conventional engine. Finally, given the vehicle’s age and the lighting history, ensure all electrical connections are secure, especially around the rear lighting assembly, and that any recent repairs to the wiring harness have been properly insulated and protected from environmental exposure. A comprehensive fluid check—including brake fluid, coolant, and transmission fluid—should also be performed, as fluids degrade over time even with low mileage, particularly if the vehicle has been stationary for prolonged periods without fluid circulation.
