Renault Trucks Unclassified MOT Reliability Overview
The Renault Trucks Unclassified is a niche vehicle in the UK, with 1,923 MOT test results recorded in our database spanning 9 manufacture years. It has an overall MOT pass rate of 63.9% and a failure rate of 36.1%, which is around the UK average of approximately 37%.
Based on this data, the Renault Trucks Unclassified earns a "Average" reliability rating. The average Renault Trucks Unclassified presents for MOT with approximately 135,160 miles on the clock. Manufacture year matters: 2011 models achieve the highest pass rate at 73.7%, while 2014 models have the lowest at 36.5%. This 37.2 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Renault Trucks Unclassified is Brakes, affecting 43.0% 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 Lamps, reflectors and electrical equipment at 40.4%. Suspension rounds out the top three at 23.8%. 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 Renault Trucks Unclassified shows a moderate increase in MOT failures after warranty. The 22% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 5 (42.8% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Unclassified is likely to perform.
Brakes — 43.0% of failures
Brakes issues account for 43.0% of MOT failures on the Renault Trucks Unclassified. 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).
Lamps, reflectors and electrical equipment — 40.4% of failures
Lamps, reflectors and electrical equipment issues account for 40.4% of MOT failures on the Renault Trucks Unclassified. 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.
Suspension — 23.8% of failures
Suspension issues account for 23.8% of MOT failures on the Renault Trucks Unclassified. 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.
