2021 Tesla Model 3 Long Range AWD Electric · NG71 DFK

The most recent MOT test on the 2021 Tesla Model 3 Long Range AWD, conducted on 2025-11-27, resulted in a passing grade, though it included several recurring advisories that suggest a pattern of wear-related issues rather than outright failure. The advisories on brake disc wear—both near- and offside front and rear—indicate that the braking system is experiencing progressive surface degradation, likely due to consistent use or uneven braking habits. This trend is concerning because while the discs are not yet critically compromised, their pitting and scoring could escalate over time, potentially leading to reduced braking efficiency, increased noise, or even premature disc replacement if not addressed. The front tyres also showed wear close to the legal limit, particularly on the offside and near-side, which may reflect directional bias in braking or alignment issues. The fact that these advisories have persisted across multiple tests suggests that the vehicle’s braking system may be under stress, warranting closer attention to ensure no underlying mechanical issues are developing. The recorded mileage of 25,443 miles for a vehicle aged five years represents a relatively low annual usage rate of approximately 5,089 miles per year, which is unusually low for its age. Such low mileage can stem from infrequent use, long periods of inactivity, or deliberate low-mileage ownership, but it also raises questions about potential neglect in other areas. Vehicles that stand for extended periods without movement can suffer from standing corrosion, particularly in the wheel arches, undercarriage, and brake components, as moisture and road salt accelerate rust formation. Additionally, fluids like brake fluid and transmission fluid degrade over time, even when not actively used, which can compromise performance and safety. The absence of higher mileage figures might also suggest that the vehicle has not been subjected to the typical wear and tear associated with daily or frequent driving, but this does not absolve the need for thorough inspection to confirm that no hidden issues have arisen from prolonged inactivity. For a prospective buyer, the advisories on brake disc wear and tyre wear close to legal limits necessitate immediate attention. During a test drive, listen for unusual brake noise or vibration, which could indicate warping or uneven disc wear. Check for a shudder or pulsation when applying the brakes, as this may signal binding calipers or flexing brake discs. Inspect the brake discs visually for deep grooves, scoring, or signs of glazing, and measure their thickness to ensure they remain above the minimum legal specification. The front tyres, in particular, should be rotated to even out wear patterns, and any directional bias should be addressed to prevent further uneven wear. Given the history of rear tyre failures, ensure both rear tyres are fully compliant with the 1.6mm tread depth requirement before purchase. Beyond the MOT advisories, conduct a thorough inspection of the vehicle’s undercarriage for signs of rust, particularly around the wheel wells and suspension components, as prolonged standing can accelerate corrosion. Check the brake fluid level and condition, as old or contaminated brake fluid can lead to reduced braking performance. Additionally, verify that the vehicle’s service history is up to date, especially for fluid replacements and brake system servicing, as Tesla’s recommended maintenance intervals may differ from conventional internal combustion engine vehicles. If the vehicle has been stored for extended periods without use, the buyer should also focus on practical checks relevant to its low-mileage, long-term storage profile. Inspect the tyre sidewalls for signs of perishing or cracking, which can occur from age-related degradation even at low mileage. Check the 12V battery health, as prolonged disuse can lead to reduced capacity or corrosion in the terminals. Listen for any unusual noises from the suspension, such as clunks or rattles, which may indicate worn suspension bushes or coil spring damage. Verify that all fluid levels are correct and that there are no visible leaks, as standing fluids can corrode internal components. Given the vehicle’s age and the advisories noted, it is prudent to request a detailed service history to confirm that all scheduled maintenance, including brake system servicing and fluid replacements, has been completed. Finally, consider a professional pre-purchase inspection to assess the structural integrity of the vehicle, particularly in areas prone to rust, and to confirm that the braking and tyre systems meet current safety standards.
