2020 Tesla Model 3 Performance AWD Electricity · 2 FEN

The Tesla Model 3 Performance AWD has maintained a clean MOT record in its most recent test, passing without defects at 78,168 miles in February 2026. The trend over the past two years suggests improving maintenance discipline, as the vehicle cleared all tests since the February 2024 failure—though that failure itself was due to straightforward consumable issues rather than structural or mechanical neglect. The absence of advisories in the latest test indicates no lingering concerns about suspension components, brake binding, or corrosion, which are common points of failure in high-mileage EVs. That said, the February 2024 failure on both rear tyres and brake discs highlights a period where basic upkeep was deferred, though this appears to have been addressed promptly. The mileage accumulation is notably aggressive for a six-year-old vehicle, averaging around 13,000 miles annually—a rate that accelerates wear on suspension bushes, brake friction materials, and tyre compounds. The gap between the 2023 test (20,089 miles) and the 2024 failure (24,969 miles) suggests the car was driven heavily in that interval, yet the subsequent 23,000-mile jump to 48,118 miles by March 2025 implies either a second owner or a change in usage patterns. The most recent 30,000-mile span to 78,168 miles in early 2026 was covered without MOT issues, pointing to either diligent post-failure maintenance or a shift to lighter use. Without a full service history, it’s impossible to confirm whether critical components like the rear differential, motor cooling system, or high-voltage battery have been serviced to manufacturer specifications. For a buyer, the priority should be a thorough inspection of the rear brake system, given the 2024 pitted disc advisories and the failure on tread depth. Binding calipers or uneven wear on the discs could indicate misalignment or fluid contamination, both of which are more common in EVs due to regenerative braking demands. The near-side rear tyre damage in 2025—though repaired—warrants checking for kerbing, pothole impacts, or uneven suspension wear, particularly on the rear coil springs or anti-roll bar links. Structural integrity is less of a concern given the absence of corrosion advisories, but a close look at the underbody for hidden rust in high-stress areas (e.g., subframe mounts, suspension towers) is still advisable. Finally, verify the battery health and cooling system, as these are often overlooked in used EVs despite being critical to long-term reliability.
