2023 Tesla Model Y RWD Electricity · P121 TKD

The most recent DVSA MOT test for the 2023 Tesla Model Y RWD, conducted on 2026-04-09, resulted in a clean pass with no recorded defects or advisories. This outcome represents a stable maintenance trend, as there is no prior MOT history available to compare against, but the absence of any failures or warnings suggests that the vehicle has met the roadworthiness standards set by the DVSA to date. The lack of advisories—particularly those that could indicate developing issues such as fluid leaks, excessive wear, or structural concerns—implies that the vehicle has likely been maintained within acceptable operational parameters. However, the absence of a prior MOT record means any potential historical wear or service history remains unquantified, so caution should be exercised in assuming long-term reliability without further inspection or service records. The recorded mileage of 48,841 miles for a vehicle aged three years is notably high, translating to approximately 16,280 miles per year. This usage rate is significantly above the average for a three-year-old car, which typically accumulates around 5,000–10,000 miles annually under normal conditions. Such high mileage suggests either intensive use, frequent short trips, or prolonged periods of inactivity followed by rapid acceleration. Mechanically, this elevated mileage accelerates wear on consumables such as brake pads and linings, suspension components like coil springs and bushings, and drivetrain elements including the transmission fluid and drive belts. The rapid wear progression could lead to premature failure of critical systems if not addressed, particularly in components prone to friction or stress, such as the brakes or suspension. Additionally, the absence of a service history or mileage-based maintenance records means that time-based servicing—such as fluid top-ups or replacements—may not have been conducted at the recommended intervals, increasing the risk of hidden issues developing. As a prospective buyer, the most critical physical checks for this vehicle should focus on the brake system, suspension, and fluid condition, given its high mileage and age. Begin by inspecting the brake discs and linings for signs of excessive wear, corrosion, or glazing, which could indicate thinning or binding calipers. Listen for unusual brake pulsation or shudder during a test drive, as this may signal warped discs or uneven lining wear. The suspension should be examined for excessive play or clunking noises, particularly when driving over bumps, which could point to worn coil springs, broken suspension arms, or deteriorated bushings. Check under the vehicle for any signs of fluid leaks, especially around the brake master cylinder, transmission, and differential, as oil or coolant leaks could compromise system integrity. Additionally, verify the condition of the tyres, ensuring they have sufficient tread depth and no signs of sidewall cracking or perishing, which can compromise handling and safety. Given the vehicle’s age and usage profile, the battery health should also be scrutinised, as Tesla batteries degrade over time, particularly under high mileage or frequent short trips. A visual inspection for corrosion around the battery terminals and a check of the battery’s voltage and charge cycle life would be prudent. Fluid servicing is another critical area; while Tesla vehicles are known for their longevity, the transmission fluid and coolant should be checked for degradation, which can occur over time even without high mileage. If the vehicle has been in use for over three years, consider a professional inspection of the drivetrain and electrical systems, as Tesla’s proprietary diagnostics may reveal underlying issues that are not always flagged by standard MOT tests. Finally, since the vehicle has not undergone a recent MOT, a thorough pre-purchase inspection by a qualified mechanic is strongly recommended to confirm the absence of hidden defects and ensure compliance with UK roadworthiness standards.
