2021 BMW IX3 Premier Edition PRO Electric · PY71 AHO

The roadworthiness profile of this 2021 BMW iX3 is shaped almost entirely by tyre condition, with two tests on file showing a clean pass at the most recent examination on 14 October 2025 and only a single prior test on 12 December 2024 that carried advisories. The 2024 test noted that both rear tyres were worn close to the legal limit and worn on the edge, alongside a separate advisory for a cut on the nearside rear tyre that did not penetrate to the ply or cords. There are no recorded failures, no structural or corrosion advisories, and no brake, suspension, or lighting defects on the MOT history, which means the documented evidence is limited to two tests over a roughly twelve-month span and is heavily concentrated on rear-axle tyre wear rather than broader mechanical deterioration. Mileage accumulation is broadly typical for a five-year-old vehicle, with 41,985 recorded miles equating to around 8,400 miles per year since registration. This is a moderate annual figure that suggests regular but not exhaustive use, which for an electric drivetrain generally means less thermal stress on the motor and inverter than a high-mileage example might experience, while still placing realistic wear demands on the suspension, steering, and underbody components. The gap between the two recorded MOT tests is just under ten months, which is consistent with a vehicle that has remained in continuous use rather than being laid up for extended periods, and there is no mileage jump or anomaly that would suggest clocking concerns or intermittent operation. Within those recorded mileages, the rear tyres reaching the legal limit at the 2024 test is a reasonable finding given the inherent rear-biased weight distribution and regenerative braking forces characteristic of this platform, which can accelerate shoulder wear on the driven or heavily loaded axle. For a prospective buyer, the primary inspection focus should be the rear tyres and the surrounding suspension geometry, since the MOT history flags edge wear on both rear tyres simultaneously, which can be indicative of either alignment drift, worn rear suspension bushes, or consistent overloading. On a test drive, listen for any clonking or knocking from the rear suspension over uneven surfaces, particularly over speed humps and rough tarmac, and pay attention to whether the vehicle tracks straight without a steering pull, as uneven rear tyre wear is frequently accompanied by a slight rear axle misalignment. Inspect the sidewalls of all four tyres for uneven shoulder wear, cracking, or blistering, and check the date codes to confirm they are recent replacements rather than original factory fitments carried beyond their service life. The nearside rear cut noted in 2024 should also be verified as fully resolved with no slow leaks, and a thorough inspection of the spare or repair kit condition is advisable given the previous sidewall damage. Secondary checks should concentrate on the items the MOT history does not address, particularly because only two tests are recorded for a five-year-old vehicle. The braking system warrants a physical inspection of disc condition and pad thickness, as the regenerative braking system on the iX3 reduces conventional brake use but does not eliminate corrosion of the discs during periods of light application, leading to potential judder under firm pedal pressure. The underside of the vehicle should be examined for any corrosion on subframe mounting points, brake pipe routing, and the multi-link rear suspension components, given that even modest annual mileage in the UK can produce surface oxidisation on exposed ferrous parts. Finally, confirm the high-voltage battery state of health through the diagnostic menu, as the MOT test does not assess traction battery capacity, and verify that the charging cable, port, and onboard charger function correctly, since these items are outside the scope of the standard roadworthiness examination.
