2023 Tesla Model Y RWD Electric · ML23 AAF

The most recent MOT test on 2026-03-30 resulted in a passing outcome, but this follows a failure on 2026-03-26, where two dangerous defects were recorded: the near-side front tyre exhibited exposed tyre cords or plies at the inner edge, a critical failure under 5.2.3(d)(ii) indicating severe internal tyre damage likely from overinflation, underinflation, or excessive heat exposure, and the offside rear tyre had a tread depth below the legal minimum of 1.6mm, which poses a significant risk of hydroplaning. While the vehicle now meets roadworthiness standards, the presence of advisories on both front and rear tyres—near-side front tyre worn to within 3mm of the legal limit and offside rear tyre worn to within 2.5mm—suggests a pattern of uneven wear that could indicate misalignment, incorrect tyre pressure, or improper wheel balancing. The failure-to-pass trend highlights a need for immediate attention to tyre integrity, as exposed cords are a clear sign of compromised tyre structure, which can lead to sudden failure and loss of control. The vehicle’s recorded mileage of 45,617 miles at a 2023 model year represents a high annual usage rate of approximately 15,206 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables such as brake pads, suspension components, and drivetrain elements, including the transmission and differential. The absence of significant mileage gaps suggests either intensive use or a lack of regular maintenance, both of which can exacerbate mechanical stress. For a Tesla Model Y, particularly one with this level of usage, the risk of accelerated tyre wear, suspension degradation, and potential electrical component fatigue becomes more pronounced, warranting a thorough inspection of all high-wear areas and adherence to a preventive maintenance schedule. Given the recent MOT failures and advisories, the prospective buyer should prioritise a comprehensive physical inspection of the tyres, suspension, and braking system. First, verify the exposed cords in the near-side front tyre by visually inspecting the tread and sidewall for any signs of bulges, cracks, or separation, and confirm that the tyre has been replaced to meet current standards. During a test drive, listen for unusual noises such as a grinding or squealing sound from the front brakes, which could indicate worn pads or warped discs, and check for uneven braking performance or pull to one side. The offside rear tyre’s severe wear should prompt immediate replacement, as a tread depth below 1.6mm is unsafe and may require retreading if the tyre is otherwise serviceable. Additionally, inspect the wheel alignment and tyre pressure to address the underlying causes of uneven wear, as misalignment or incorrect pressure are common culprits. Beyond the immediate tyre concerns, the buyer should also examine the vehicle’s suspension for signs of wear, particularly the coil springs, shock absorbers, and suspension bushes, which may exhibit clunking or rattling when driving over bumps. Check for any fluid leaks around the wheels, brakes, and undercarriage, as fluid degradation or contamination can accelerate component failure. Given the vehicle’s age and high mileage, consider a professional inspection of the electrical system, including the 12V battery, as Tesla vehicles are prone to battery degradation over time, which can lead to reduced performance or complete failure. Finally, review the vehicle’s service history to ensure that time-based maintenance, such as fluid top-ups (brake fluid, coolant, and transmission fluid), has been conducted according to manufacturer recommendations, as fluid degradation can compromise system efficiency and safety. If possible, obtain a detailed service report to confirm compliance with the manufacturer’s maintenance schedule.
