Infiniti Qx50 MOT Reliability Overview
The Infiniti Qx50 is a rare vehicle in the UK, with 456 MOT test results recorded in our database spanning 3 manufacture years. It has an overall MOT pass rate of 84.9% and a failure rate of 15.1%, which is well above the UK average of approximately 37%.
Based on this data, the Infiniti Qx50 earns a "Excellent" reliability rating. The average Infiniti Qx50 presents for MOT with approximately 43,363 miles on the clock. Manufacture year matters: 2016 models achieve the highest pass rate at 86.8%, while 2014 models have the lowest at 74.6%. This 12.2 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Infiniti Qx50 is Tyres, affecting 20.2% of all tests. 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. The second most common issue is Brakes at 19.7%. Noise, emissions and leaks rounds out the top three at 3.1%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Qx50 is likely to perform.
Tyres — 20.2% of failures
Tyres issues account for 20.2% of MOT failures on the Infiniti Qx50. 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.
Brakes — 19.7% of failures
Brakes issues account for 19.7% of MOT failures on the Infiniti Qx50. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Noise, emissions and leaks — 3.1% of failures
Noise, emissions and leaks issues account for 3.1% of MOT failures on the Infiniti Qx50. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
