2021 Tesla Model 3 Standard Range + Electric · VA66 RYA

The most recent MOT test conducted on 04 October 2025 resulted in a pass, though it introduced a new advisory regarding the offside rear upper suspension arm pin or bush being worn. Looking at the recent history, the maintenance trend appears somewhat reactive. The vehicle suffered a dangerous failure in November 2024 due to insufficient tread depth on both rear tyres, which was subsequently rectified to achieve a clean pass in late 2024. The emergence of a suspension advisory in the latest test suggests that while immediate safety compliance is being met, the vehicle is beginning to show signs of component degradation that will require attention in the near future. With 27,526 miles recorded over five years, this vehicle has averaged approximately 5,505 miles per year, which is notably low for a Tesla Model 3. While this lower mileage implies reduced wear on the electric motors and drivetrain, it also suggests the vehicle may have been subject to long periods of inactivity. Low-use vehicles can often present different mechanical challenges than high-mileage counterparts, specifically regarding the degradation of rubber components and the potential for fluid stagnation or component seizure due to lack of regular operation. Regarding the specific advisory, the worn offside rear upper suspension arm pin or bush is a key area for inspection. During your test drive, pay close attention to the rear of the vehicle when driving over speed bumps, potholes, or uneven road surfaces. Listen for any dull knocking, clunking, or creaking sounds emanating from the rear suspension, as these are classic symptoms of a perished or worn bush. If the component is allowed to deteriorate further, it may lead to compromised handling and accelerated, uneven wear on the rear tyres. Given the low annual mileage, you should also perform a thorough physical inspection of the tyres for signs of perishing or sidewall cracking, which can occur due to age even if the tread remains deep. Check the brake discs for excessive surface corrosion or pitting, and ensure the calipers are not binding, as infrequent use can cause brake components to seize or stick. It is also advisable to verify the 12V auxiliary battery's condition and confirm that time-based maintenance, such as brake fluid replacement, has been carried out according to the manufacturer's schedule, as these items are critical for long-term reliability in low-usage electric vehicles.
