Infiniti Q70 MOT Reliability Overview
The Infiniti Q70 is a niche vehicle in the UK, with 2,116 MOT test results recorded in our database spanning 4 manufacture years. It has an overall MOT pass rate of 84.4% and a failure rate of 15.6%, which is well above the UK average of approximately 37%.
Based on this data, the Infiniti Q70 earns a "Excellent" reliability rating. The average Infiniti Q70 presents for MOT with approximately 52,161 miles on the clock. Manufacture year matters: 2014 models achieve the highest pass rate at 92.9%, while 2015 models have the lowest at 81.9%. This 11.0 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Infiniti Q70 is Tyres, affecting 18.7% 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 18.0%. Suspension rounds out the top three at 8.1%. 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 Infiniti Q70 ages relatively gracefully. The failure rate increase of 18% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 9 (25.7% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Infiniti Q70 MOT Data
The Infiniti Q70 is a niche vehicle in the UK, with 2,116 MOT test results recorded in our database spanning 4 manufacture years. It has an overall MOT pass rate of 84.4% and a failure rate of 15.6%, which is well above the UK average of approximately 37%.
For Infiniti Q70 owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on tyres and brakes 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 Q70 is likely to perform.
Tyres — 18.7% of failures
Tyres issues account for 18.7% of MOT failures on the Infiniti Q70. 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 — 18.0% of failures
Brakes issues account for 18.0% of MOT failures on the Infiniti Q70. 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 — 8.1% of failures
Suspension issues account for 8.1% of MOT failures on the Infiniti Q70. 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.
