2020 Tesla Model 3 Performance AWD Electric · SL20 AAO

The defining mechanical story across this Tesla Model 3's MOT history centres on brake and tyre condition rather than structural or suspension concerns, with the June 2026 test sequence demonstrating a clear deterioration in these areas. The vehicle passed its most recent MOT on 19 June 2026, but only after a prior failure six days earlier on 13 June 2026 attributed to a dangerous nearside front tyre tear caused by structural separation. Both the 2026 tests recorded advisories for pitted and scored brake discs on all four corners, mirroring advisories that had appeared on the 2023 test for front tyre wear and edge cracking. The 2025 test was largely clean apart from a minor nearside front tyre damage advisory, and the 2024 test passed without any recorded defects, indicating that the wear pattern is concentrated in the most recent twelve months rather than being a chronic long-standing issue. The pattern suggests an evolving rather than static condition, with brake disc surface degradation and tyre integrity becoming the primary areas of concern as the vehicle accumulates road use in its sixth year. Mileage data is not provided alongside the MOT records, so it is not possible to calculate a precise annual accumulation rate or identify any specific usage anomaly. The five tests span from May 2023 to June 2026, covering a three-year testing window for a 2020 vehicle, which represents a standard annual MOT cadence with no extended gaps off the road that would suggest a lay-up period or storage. Without odometer readings it is not possible to confirm whether the vehicle has covered typical mileage for a six-year-old performance model or whether usage has been unusually low or high. Mechanically, the absence of multi-year testing gaps means there is no evidence of extended standing, so concerns such as seized calipers from inactivity, brake disc corrosion beyond surface pitting, or 12V auxiliary battery deterioration from long lay-ups cannot be inferred from the test cadence alone. Any assessment of usage-related wear would need to be supplemented by a direct odometer check at the point of viewing. A prospective buyer should focus their physical inspection on the brake system, as the recurring pitted and scored disc advisories on all four corners indicate surface wear that may be approaching the threshold where disc replacement becomes necessary. On a test drive, listen for any brake squeal or grinding under light application, feel for pedal pulsation or judder through the footwell which would suggest disc runout or uneven wear, and check for any pulling to one side under braking that could indicate a binding caliper. Inspect the discs visually through the wheel spokes for a pronounced lip on the outer edge and for any blueing or heat discolouration, both of which would confirm the surface degradation noted in the advisories. The brake fluid should also be assessed for age, as a six-year-old performance vehicle operating in heavy braking conditions typically benefits from fluid replacement every two to three years irrespective of MOT findings. Tyre condition warrants equally close scrutiny given the dangerous failure recorded in June 2026 and the earlier 2023 advisories for worn edges and cracking on both front tyres. On inspection, examine all four tyres for uneven shoulder wear particularly on the inner and outer extremes, as edge wear on a high-performance all-wheel-drive vehicle can indicate suspension geometry issues, incorrect alignment, or prolonged cornering on under-inflated tyres. Feel for any vibration through the steering wheel at speed which could suggest a separating tyre carcass before visible damage appears, and check the sidewalls carefully for bulges, cracks, or areas of discolouration that may indicate structural compromise. Given the performance specification and the documented tendency towards aggressive tyre wear, confirming the manufacturing date of the fitted tyres is worthwhile, and budgeting for a full set replacement alongside potential brake disc refurbishment would be a prudent precaution for a vehicle of this age and performance classification.
