2021 Tesla Model 3 Long Range AWD Electric · AF71 ONS

The most recent DVSA MOT test for this 2021 Tesla Model 3 Long Range AWD was conducted on 2025-09-03 and resulted in a failure, with the primary defect being an excessively worn offside rear upper suspension arm ball joint classified under DVSA standard 5.3.4(a)(i). This failure marks a clear deviation from the previous two MOT outcomes, which were both passed, indicating a significant maintenance or mechanical issue that has not been resolved. The advisory of under shields fitted in both the failed and passed tests suggests either a recurring or persistent need for protective coverings, potentially linked to the suspension component failure, though this does not directly impact roadworthiness. The pattern of results highlights a need for immediate attention to the suspension system, as the ball joint failure is a critical structural component that, if left unrepaired, could lead to further suspension failure, wheel misalignment, or even vehicle instability during operation. The recorded mileage of 69,585 miles for a vehicle aged five years represents a high annual usage rate of approximately 13,917 miles per annum, which is notably elevated for a car of this age and model. Such mileage accumulation typically indicates either intensive driving conditions, frequent short trips, or a combination of both, which can accelerate wear on consumables like brake pads, suspension components, and drivetrain elements. The absence of significant mileage gaps between tests suggests consistent usage, which may have contributed to the observed suspension wear. However, the high mileage does not alone explain the ball joint failure, as this is a structural component that can degrade from both usage and environmental factors, such as road conditions or exposure to moisture and debris. Buyers should be aware that this level of mileage may warrant closer attention to wear on suspension bushes, coil springs, and other related components, as well as potential issues with the vehicle’s electrical or hybrid systems, which can also be influenced by high usage. Given the recent MOT failure and the critical nature of the offside rear upper suspension arm ball joint failure, the prospective buyer must prioritise addressing this defect before proceeding with purchase. The ball joint is a pivotal component that connects the suspension arm to the wheel assembly, providing both stability and steering control. Symptoms of a failing ball joint during a test drive may include clunking noises from the rear suspension when driving over bumps or uneven surfaces, a feeling of uneven wheel alignment, or a noticeable pull to one side of the vehicle. The buyer should also inspect for signs of excessive play or binding in the rear suspension when the vehicle is lifted on a hoist, and listen for any unusual grinding or rattling noises when the vehicle is in motion. Immediate repair of the ball joint is essential to prevent further suspension damage, potential wheel misalignment, and the risk of a catastrophic failure that could compromise vehicle control. The buyer should seek a qualified mechanic to assess the extent of the damage, confirm the need for replacement, and ensure that the suspension arm and associated components are fully inspected and repaired. In the interim, the buyer should conduct a thorough physical inspection of the vehicle to identify any additional wear or damage that may have occurred since the last MOT. This includes checking for signs of fluid leaks, particularly around the suspension, exhaust, and electrical connections, as well as verifying the condition of the tyres for uneven wear patterns or signs of hydroplaning risk. The high mileage also warrants a review of the vehicle’s brake system, including inspecting brake discs for corrosion, warping, or binding calipers, as well as checking the brake fluid level and condition for any signs of contamination or degradation. Given the vehicle’s age and usage profile, the buyer should also consider a comprehensive electrical system check, as high mileage can accelerate wear on wiring harnesses, connectors, and battery health. Additionally, the buyer should verify that the vehicle’s service history, including any scheduled maintenance such as fluid top-ups, tyre rotations, and suspension inspections, has been documented. If the buyer is unable to confirm the repair of the ball joint before purchase, they should insist on a written agreement outlining the scope of work and timeline for completion to ensure the vehicle’s roadworthiness and safety.
