2020 Tesla Model 3 Long Range AWD Electric · WN20 DKA

The most recent DVSA MOT test for this 2020 Tesla Model 3 Long Range AWD was conducted on 2026-06-10 and resulted in a pass, marking the vehicle’s most recent compliance with roadworthiness standards. Despite a single failure recorded in 2025-06-04—specifically a failure due to insufficient front windscreen washer liquid—this has not recurred in the intervening period, indicating a stable maintenance trend. The absence of further defects or advisories in the past two years suggests that, mechanically, the vehicle has not exhibited significant issues during routine testing, though the lack of a front washer fluid reservoir is a minor but persistent advisory that could contribute to reduced windscreen visibility in wet conditions if not addressed promptly. The recorded mileage of 21,969 miles for a vehicle aged six years represents an annual usage rate of approximately 3,662 miles, which is notably lower than the typical wear rates for similarly equipped petrol or diesel cars of comparable age. This low mileage could imply either infrequent use, long periods of stationary storage, or a preference for alternative transportation methods. However, such usage patterns may accelerate wear on certain consumables and components that are less frequently cycled, such as brake systems, suspension elements, and fluids that degrade over time due to prolonged inactivity. For example, standing vehicles can lead to brake disc corrosion or caliper binding if moisture penetrates the brake system, while fluids like brake fluid and differential oil may become contaminated or degraded if not regularly replenished. Given the clean MOT history aside from the windscreen washer advisory, the buyer should conduct a thorough physical inspection to address potential issues arising from low mileage and age. Focus on the front brake system, particularly the discs and calipers, to check for signs of corrosion or binding, which can occur when the vehicle stands for extended periods without braking. Inspect the suspension components, including coil springs, shock absorbers, and suspension bushes, for signs of wear or excessive play, as these may not have been fully cycled under load. The tyres should be examined for sidewall perishing or cracking, which can weaken the rubber and compromise safety, especially if the vehicle has been stored for long periods without use. Additionally, verify the condition of the 12V battery and its connections, as prolonged disuse can lead to reduced charge capacity or corrosion in the terminals. The buyer should also prioritise time-based maintenance for fluids that degrade over time, regardless of mileage. Check the brake fluid level and condition, as brake fluid absorbs moisture and can become gelled if left unused for prolonged periods, compromising braking performance. Inspect the differential and transmission fluids for contamination or degradation, ensuring they are topped up and replaced according to Tesla’s recommended intervals, even if the vehicle has not been driven frequently. Finally, a visual and functional check of the exhaust system for leaks or excessive noise, along with a test drive to assess for any unusual vibrations, clunks, or emissions-related symptoms, would be prudent. If the vehicle has been stored in a damp or extreme environment, further checks for rust on the chassis or undercarriage may be necessary, as Tesla’s bodywork can be susceptible to corrosion over time, particularly in low-mileage models that have not been regularly driven.
