2017 Tesla Model S Electric · LC67 PZP

The latest MOT test results for the 2017 Tesla Model S reveal a critical failure in September 2025, with two dangerous defects identified: an offside front lower suspension arm ball joint that poses a risk of detachment, and exposed tyre cords on the offside front tyre, indicating severe tread degradation and structural compromise. This follows a previous MOT failure in March 2024, where the nearside rear tyre also exhibited exposed cords and front tyres were worn dangerously close to legal limits. While the vehicle passed MOTs in 2023 and 2024, the pattern of recurring tyre and suspension-related issues suggests a concerning maintenance trend, with the ball joint failure being particularly alarming as it directly threatens structural integrity and roadworthiness. The advisories from the April 2026 test—such as corroded rear inner brake discs and sidewall scuffing—further highlight ongoing wear concerns, particularly in components that require regular attention to prevent escalation. The vehicle’s recorded mileage of 56,022 miles at the time of assessment represents a moderate annual usage rate of approximately 6,225 miles, which is typical for a nine-year-old car with no evidence of excessive wear from high mileage alone. However, the MOT history indicates periods of potential underuse or prolonged standing, as evidenced by the repeated advisories from 2021 and 2023, where tyres were worn dangerously close to legal limits and sidewall damage was noted. This suggests that the vehicle may have sat for extended periods without regular use, which can accelerate wear in components like tyres, brakes, and suspension, particularly in areas prone to corrosion or dry-rotting. The rapid accumulation of mileage in the final two years—from 50,000 to over 56,000—also warrants closer inspection, as this could indicate increased stress on consumables, brakes, and drivetrain components, though the suspension ball joint failure in 2025 stands out as a red flag regardless of usage pattern. For a prospective buyer, the most critical inspection should focus on the suspension system, particularly the offside front lower arm ball joint, which failed the MOT in 2025. Visually inspect the area around the joint for signs of play, excessive wear, or oil leaks, and listen for unusual clunking or rattling when driving over bumps or at speed. The exposed tyre cords and severe tread wear on the offside front tyre necessitate immediate replacement, as further deterioration could lead to a dangerous failure. During a test drive, monitor the vehicle for uneven tyre wear, which may indicate misalignment or suspension issues, and check for any vibration or pulling sensations that could signal binding calipers or warped brake discs. The corroded rear inner brake discs from the April 2026 MOT should also be inspected for rust buildup, which could compromise braking performance; consider replacing them if they show signs of excessive corrosion or binding. Beyond the immediate defects, the buyer should conduct a thorough physical inspection for signs of age-related wear and potential standing corrosion. Given the vehicle’s age and the advisories of sidewall scuffing and cuts, examine the tyres for signs of perishing or cracking in the sidewalls, which can weaken their structural integrity over time. Check the brake system for corrosion on the rear inner discs and ensure the calipers are free from binding, as prolonged standing can cause rust to accumulate on brake components. Additionally, verify the condition of the 12V battery, as Tesla vehicles often require attention to ensure it remains functional, especially if the car has been stored for extended periods. Fluid servicing should also be considered, with particular attention to the brake fluid, which can degrade over time even without use, and the suspension fluid, which may need replacement every 60,000–100,000 miles or every 5 years to maintain optimal performance. Finally, review the service history for any missing or outdated maintenance records, particularly for the suspension and tyre systems, as these are critical areas where the vehicle has shown recurring issues.
