2017 Tesla Model X Electricity · LB17 WMK

The Tesla Model X in question presents an unusual but technically compliant MOT history, with the most recent test in May 2025—just over a year ago—showing no defects recorded on two consecutive passes, despite two prior failures in the same week. The absence of any advisories or defects in the last two tests suggests the vehicle’s core mechanical and structural systems were deemed roadworthy at 54,776 miles, though the repeated failures in May 2024 and May 2025 (all without listed defects) indicate a procedural or administrative issue rather than recurring mechanical faults. Given the lack of technical failures, there is no evidence of worsening wear trends; however, the pattern of back-to-back passes and fails within days raises questions about whether the vehicle was presented for retesting after minor, unrecorded adjustments. For a buyer, this clean slate in the latest tests is positive, but the absence of documented advisories or defects—particularly for a vehicle of this age and technology—may warrant closer scrutiny of service records for less obvious wear, such as battery health or regenerative braking system calibration. The mileage accumulation of 6,086 miles per year aligns with typical low-to-moderate usage for a nine-year-old vehicle, suggesting it has not been subjected to excessive wear from high annual distances. The recorded mileage jumps from 51,588 miles in May 2024 to 54,776 miles in May 2025 indicate roughly 3,188 miles covered in the intervening year, a pace consistent with occasional rather than daily use. There are no red flags in the mileage pattern—no sudden spikes or prolonged periods of inactivity—that might imply neglect or abuse. However, the lack of mileage progression between the three tests in May 2024 (all within 48 hours) is anomalous and may reflect a deliberate strategy to minimise recorded mileage or an error in logging. For a buyer, this stability in mileage is neutral; the vehicle has not been overworked, but the clustering of tests warrants confirmation that the odometer reflects genuine usage. Given the MOT record’s lack of technical defects, a buyer should prioritise an independent inspection of components not routinely covered by standard MOT checks, particularly those critical to the Model X’s hybrid powertrain and autonomous features. The regenerative braking system, battery pack cooling, and high-voltage wiring should be assessed for signs of wear or damage, as these are not visually inspected during MOTs but are central to performance and safety. Additionally, while the MOT does not test for corrosion in Tesla’s predominantly aluminium body, a thorough check for any hidden rust in suspension mounts, brake lines, or underbody components is advisable, especially if the vehicle has been garaged in salty or humid conditions. The absence of advisories on tyres, brakes, or suspension in the latest tests is encouraging, but a pre-purchase inspection should verify tread depth, brake pad thickness, and the condition of coil springs or anti-roll bar bushes, which may degrade without MOT visibility. Finally, the vehicle’s software and infotainment systems should be tested for responsiveness, as electrical gremlins are common in high-tech vehicles and rarely captured in MOT records.
