Sinnis Qm MOT Reliability Overview
The Sinnis Qm is a rare vehicle in the UK, with 911 MOT test results recorded in our database spanning 4 manufacture years. It has an overall MOT pass rate of 77.4% and a failure rate of 22.6%, which is well above the UK average of approximately 37%.
Based on this data, the Sinnis Qm earns a "Excellent" reliability rating. The average Sinnis Qm presents for MOT with approximately 6,744 miles on the clock. Manufacture year matters: 2015 models achieve the highest pass rate at 82.5%, while 2018 models have the lowest at 66.7%. This 15.8 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Sinnis Qm is Motorcycle lamps and reflectors, affecting 25.9% of all tests. 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. The second most common issue is Motorcycle structure and attachments at 14.5%. Motorcycle brakes rounds out the top three at 10.5%. 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 Sinnis Qm ages relatively gracefully. The failure rate increase of 14% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 5 (27.0% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

For Sinnis Qm owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on motorcycle lamps and reflectors and motorcycle structure and attachments 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 Qm is likely to perform.
Motorcycle lamps and reflectors — 25.9% of failures
Motorcycle lamps and reflectors issues account for 25.9% of MOT failures on the Sinnis Qm. 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.
Motorcycle structure and attachments — 14.5% of failures
Motorcycle structure and attachments issues account for 14.5% of MOT failures on the Sinnis Qm. Motorcycle structure and attachments 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.
Motorcycle brakes — 10.5% of failures
Motorcycle brakes issues account for 10.5% of MOT failures on the Sinnis Qm. 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).
