2017 Tesla Model S Electricity · MM15 LAN

The 2017 Tesla Model S presents a mixed maintenance picture. The most recent MOT, conducted on 7 October 2025 at 53,394 miles, passed but flagged two notable advisories: a cut in the nearside front tyre tread and corrosion on both rear brake discs. This follows a pattern of recurring brake-related advisories. In the October 2024 test at 47,326 miles, both rear brake discs were again flagged as corroded and pitted, with an additional advisory for fluctuating front service brake performance. The trend is not worsening in a critical sense, but it is persistent. Brake disc corrosion has appeared in consecutive tests, suggesting the vehicle may be prone to standing periods where surface rust accumulates on friction surfaces. The tyre cut is a minor advisory, not a failure, but it warrants monitoring. The mileage profile is notably low for a nine-year-old vehicle. Recorded at 53,394 miles today, the car has covered roughly 5,933 miles per year on average. The MOT history confirms this pattern of light use, with a gap of 11,259 miles between September 2021 and October 2022, then 6,438 miles to October 2023, and 7,179 miles to October 2024. The most recent year shows just 6,068 miles added between October 2024 and October 2025. Such low annual mileage can preserve drivetrain and structural components but introduces its own risks. Extended periods of inactivity accelerate rubber degradation in suspension bushes, brake seals, and tyre sidewalls. Brake disc surface corrosion, as repeatedly flagged, is a classic symptom of a vehicle that sits unused for stretches. A prospective buyer should focus the physical inspection on the braking system and tyre condition. The rear brake discs have shown corrosion advisories in two consecutive MOTs, so check for uneven wear, lipping, and scoring beyond surface rust. The front brake fluctuation noted in 2024 may point to warped discs or inconsistent pad contact; test pedal feel and pulsation under moderate braking. Inspect the nearside front tyre closely where the cut was flagged in 2025, assessing whether it has deepened or exposed cords. Given the low mileage and likely standing periods, examine all four tyres for sidewall cracking and date codes to determine age. Suspension bushes, anti-roll bar links, and dampers should be checked for perishing, as rubber components deteriorate with time regardless of mileage. The battery state of health and charging behaviour should also be verified through Tesla's onboard diagnostics, as low-use electric vehicles can experience battery management issues from prolonged charge states.
