Mazda Mx6 MOT Reliability Overview
The Mazda Mx6 is a less common vehicle in the UK, with 8,129 MOT test results recorded in our database spanning 6 manufacture years. It has an overall MOT pass rate of 47.1% and a failure rate of 52.9%, which is significantly below the UK average of approximately 37%.
Based on this data, the Mazda Mx6 earns a "Very Poor" reliability rating. The average Mazda Mx6 presents for MOT with approximately 108,505 miles on the clock. Manufacture year matters: 1992 models achieve the highest pass rate at 51.1%, while 1995 models have the lowest at 44.3%. This 6.8 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Mazda Mx6 is Brakes, affecting 52.9% of all tests. 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. The second most common issue is Suspension at 46.8%. Exhaust, Fuel and Emissions rounds out the top three at 23.3%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?
The Mazda Mx6 shows a relatively stable failure rate after warranty — the change of 0% is negligible. Peak failure occurs at age 14 (56.1% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Mazda Mx6 MOT Data
The Mazda Mx6 is a less common vehicle in the UK, with 8,129 MOT test results recorded in our database spanning 6 manufacture years. It has an overall MOT pass rate of 47.1% and a failure rate of 52.9%, which is significantly below the UK average of approximately 37%.
For Mazda Mx6 owners, these results suggest above-average failure risk — thorough pre-MOT checks are recommended. Focus your pre-MOT checks on brakes and suspension for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Mx6 is likely to perform.
Brakes — 52.9% of failures
Brakes issues account for 52.9% of MOT failures on the Mazda Mx6. 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).
Suspension — 46.8% of failures
Suspension issues account for 46.8% of MOT failures on the Mazda Mx6. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Exhaust, Fuel and Emissions — 23.3% of failures
Exhaust, Fuel and Emissions issues account for 23.3% of MOT failures on the Mazda Mx6. 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.
