2017 Tesla Model X Electric · BT67 HDU

The vehicle most recently achieved an MOT pass certificate on 7 August 2026 with no defects or advisories recorded, which is a positive immediate indicator of roadworthiness at the time of test. However, this pass followed a failed attempt the day prior in which two dangerous tyre tread depth defects were identified at the nearside and offside front positions, alongside an advisory for nearside rear tyre wear on the edge and a further advisory for front brake disc surface deterioration. Looking at the broader trajectory, the maintenance pattern is mixed rather than deteriorating; the earlier 2025 test similarly passed with no advisories immediately after a failed attempt for registration plate presentation and windscreen wiper effectiveness, and prior passes in 2024 and 2023 were broadly clean. The recurring theme of failures being rectified within a day or two suggests the keeper is responsive to defects, but the cumulative pattern of tyre edge wear, brake disc pitting, and brake pad thinning on the nearside indicates consumables that are being worked hard, particularly given the vehicle's evident high annual usage. With 139,752 miles accumulated across approximately nine years, the recorded annual mileage equates to roughly 15,500 miles per year, which is materially higher than the UK average for a vehicle of this age and points to sustained, predominantly motorway-style driving. There are no significant gaps in the MOT history that would suggest prolonged periods of standing, and the relatively consistent annual test cycle indicates continuous use. From a mechanical standpoint, this higher mileage profile carries implications for wear on suspension components such as bushes, coil springs, and anti-roll bar links, as well as on the regenerative and friction braking system, the electric drive units, and the steering rack. High sustained mileage also tends to accelerate tyre shoulder wear, particularly on a heavy vehicle such as the Model X, and the recurring advisory history for edge wear on the front tyres is consistent with this usage pattern. For a prospective buyer conducting a physical inspection, the most pressing items relate to those already flagged in the MOT record. The nearside rear tyre should be closely inspected for both remaining tread depth and any uneven shoulder wear, as edge wear can suggest alignment geometry issues or under-inflation, and on a test drive one should listen for any increase in road noise which can indicate accelerated tread wear or casing fatigue. The front brake discs, previously noted as pitted or scored, should be examined for lip formation at the outer edge and for any roughness or juddering felt through the steering wheel or brake pedal under firm application, as pitted discs can progressively worsen and lead to uneven pad deposition. Given that the rear brake pads were previously flagged as wearing thin on both sides, the pads and caliper slide pins should be checked for service life remaining, and the calipers should be confirmed as free and not binding, which is particularly important on a vehicle that may have experienced heavy regenerative braking combined with occasional friction use. Beyond the recorded advisories, the age and mileage of this Model X warrant several time-based and wear-based inspections that the MOT itself does not fully cover. The high-voltage battery pack and its thermal management system should be reviewed through diagnostic history, as capacity retention is a critical consideration on a nine-year-old electric vehicle with substantial use, and any software updates or warranty repairs to the drive units or air suspension should be documented. Tyres fitted should be examined for sidewall perishing and DOT date codes, as even tyres with adequate tread can deteriorate from calendar age on a vehicle of this vintage, and a replacement set should be budgeted if the current ones are more than five or six years old. The air suspension system, which is characteristic of this model, should be observed for any settling on cold start, uneven ride height after the vehicle has been parked, or compressor cycling that is more frequent than expected, as these can indicate leaks or failing struts. Finally, the 12-volt auxiliary battery, brake fluid hygroscopic degradation, and the condition of the charging port, door mechanisms, and falcon wing rear door hinges all warrant specific inspection, as these are age-related service items that can present issues independently of the high annual mileage.
