2016 MINI ONE 1.2L Petrol · LS03 JUN

A notable mechanical event in this MINI's recent history is a Dangerous rear brake failure recorded on 28 June 2021, with the rear brake linings found to be less than 1.5 mm thick. This represents the most significant safety defect on file and would have required immediate rectification before the vehicle could be driven away. Since that failure, the car has returned to consistent passes, with the most recent test on 17 February 2026 recording no defects, and clean passes also logged in 2025, 2024 and 2023. A separate failed attempt on 19 June 2023, this time for a nearside headlamp aim being too low, was rectified on the same date and the vehicle subsequently passed without further comment. The 2022 test left a single advisory regarding perished rear tyre sidewalls, which is the only durability concern flagged in the last decade of testing. The overall trajectory is one of recovery after two intermittent defects, with the last three years showing a clean advisory-free record. The recorded mileage of 48,587 against a 2016 registration equates to an average of roughly 4,859 miles per year, which is notably low for the vehicle's age. The testing record shows annual submissions between 2021 and 2026 with no extended gaps, suggesting the car has been used regularly enough to keep within MOT testing cycles rather than left standing for prolonged periods. That said, the modest annual mileage means wear items such as brake friction material, tyres, suspension bushes and exhaust components are likely to have aged more from time and corrosion than from heavy mechanical use. The 2021 brake failure is consistent with this pattern, as lightly driven vehicles frequently suffer from rear brake corrosion and binding due to infrequent use rather than pad wear from mileage accumulation. Given the low annual mileage, a prospective buyer should pay particular attention to the rear braking system on inspection. The 2021 Dangerous failure for sub-1.5 mm rear linings, combined with the 2022 advisory for perished rear tyres, points to components that deteriorate through age and standing time. On a test drive, listen for any scraping or grinding from the rear hubs, which may indicate seized calipers or worn shoes, and feel for the handbrake pulling strongly to one side or requiring excessive travel. Check the rear discs for a pronounced lip on the outer edge, a sign of uneven wear or corrosion build-up, and be prepared to factor in replacement of the rear caliper carriers if the sliders have seized from infrequent use. The perished rear sidewalls flagged in 2022 should also be revisited, as tyre rubber degrades with age regardless of tread depth. Inspect the sidewalls carefully for cracking, particularly in the flex zones, and check the production date stamps as a ten-year-old set may have been replaced since but could still be approaching the end of their serviceable life. The 2023 headlamp aim failure, while minor, is worth verifying on a flat surface with the vehicle loaded to confirm the nearside beam is correctly set and that the headlamp adjusters are not worn. Beyond these specific items, listen on the test drive for any clonks or knocks from the front suspension over speed bumps, as low-mileage MINIs of this era are known for wear in the front control arm bushes and drop links, and feel for any vagueness or pull in the steering that could indicate worn tie rod ends or top mounts.
