2023 Hyundai Kona Electric · SX23 EFY

An intensive fleet-style operational pace defines this three-year-old electric vehicle, which has already accumulated 49,357 miles by the time it successfully secured an MOT pass on June 18, 2026. This clean pass followed an initial refusal of the certificate on the same day due to an ineffective nearside windscreen wiper and a major defect regarding excessive fluctuation on the offside rear service brake, accompanied by advisories for a worn, pitted, or scored offside rear brake disc and thinning rear brake pads. While the subsequent same-day pass indicates these immediate rectification points were addressed to meet statutory standards, the presence of braking system defects on a relatively young machine highlights an initial friction component wear pattern that requires careful evaluation. Averaging approximately 16,452 miles annually, this Kona EV has spent its first three years engaged in heavy-duty driving, likely involving frequent motorway commutes or commercial-style utilization. This high-intensity mileage profile places accelerated demands on the vehicle's rolling chassis, high-voltage auxiliary systems, steering linkages, and braking hardware compared to typical domestic usage. Prospective buyers should recognize that high annual mileage often accelerates the mechanical fatigue of suspension joints, wheel bearings, and regenerative braking actuators, moving wear milestones forward relative to the vehicle's age. During the pre-purchase inspection and static evaluation, meticulous attention must be paid to the rear braking assembly that triggered the recent test failure and associated advisories. On a test drive, listen carefully for any scraping, grinding, or metallic murmurs from the rear corners indicative of scored discs and depleted friction material, and pay close attention to the brake pedal feel for any pulsing or irregular engagement that might signal residual disc runout or caliper stiction. Given the regenerative braking systems fitted to modern electric vehicles, traditional friction brakes can sometimes experience uneven wear or surface degradation due to under-use, making a physical check of the disc faces essential. Additionally, verify that the replacement windscreen wiper clears the entire sweep of the glass effectively and check that all driver assistance sensors mounted near the upper windscreen are unobstructed and functioning correctly. Inspect the condition of the high-voltage underfloor shielding and suspension subframes for any signs of physical impact or premature corrosion resulting from intensive motorway miles in all weather conditions. Ensuring that the suspension absorbs road imperfections silently, without knocks or wandering alignment under braking, will confirm whether this heavy-use Kona retains structural and mechanical composure.
