About This Data

The 2021 BMW X3 has an MOT pass rate of 92.3% based on 3,771 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 24,393 miles on the odometer. With a 7.7% failure rate, the 2021 X3 is rated as "Excellent" for MOT reliability.

If you own or are considering buying a 2021 BMW X3, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating. With relatively low average mileage of 24,393 miles, many of these vehicles are still in good mechanical condition.

Tyres — 8.5% of failures

Tyres issues account for 8.5% of MOT failures on 2021 BMW X3 models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.

Lamps, reflectors and electrical equipment — 1.4% of failures

Lamps, reflectors and electrical equipment issues account for 1.4% of MOT failures on 2021 BMW X3 models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.

Non-component advisories — 0.8% of failures

Non-component advisories issues account for 0.8% of MOT failures on 2021 BMW X3 models. Non-component advisories issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
