2018 Tesla Model S Electricity · LF18 SWV

The Tesla Model S presents a generally sound mechanical picture, though the most recent MOT on 31 December 2025 at 55,925 miles introduced a notable fault after four consecutive clean passes. The tester flagged worn, pitted, or scored rear brake discs on both sides, noting the condition was not seriously weakened but still warranted an advisory. This marks a shift from the vehicle's previously unblemished record and suggests a developing issue rather than a chronic one. The trend is stable with a minor emerging concern, not yet worsening but no longer pristine. The mileage progression tells a consistent story. From 19,508 miles in February 2021 to 55,925 miles by December 2025, the car accumulated roughly 36,417 miles over nearly five years, averaging around 7,283 miles per year. That aligns closely with the typical annual figure of approximately 6,991 miles you would expect for an eight-year-old vehicle. There are no alarming gaps or sudden spikes in the odometer readings between tests. The accumulation pattern points to regular, steady use rather than prolonged standing or aggressive high-mileage driving. The rear brake disc advisory from the December 2025 test deserves close attention. Pitting and scoring on both rear discs indicate either prolonged exposure to moisture and corrosion, aggressive braking habits, or a binding rear caliper that has been dragging and unevenly wearing the friction surfaces. On an electric vehicle with regenerative braking, the rear friction brakes see less frequent use than on a conventional car, which can actually accelerate corrosion on discs that are not regularly scrubbed clean. A buyer should physically inspect the rear discs for deep scoring ridges, lipping at the edges, and uneven wear patterns. The rear calipers should be checked for seized slides or sticking pistons that could cause the discs to overheat and warp. Beyond the flagged item, the absence of suspension, structural, or emissions-related advisories across five tests is encouraging for a vehicle of this age and mileage. Still, a prospective buyer should examine the condition of the front brake discs and pads, which bear more of the braking load in a regenerative EV, and inspect the suspension bushes and coil springs for wear consistent with 55,925 miles. Tyre condition and age should also be verified, as uneven wear can hint at alignment or suspension issues not yet severe enough to trigger an MOT advisory.
