Smc Quad MOT Reliability Overview
The Smc Quad is a rare vehicle in the UK, with 300 MOT test results recorded in our database spanning 3 manufacture years. It has an overall MOT pass rate of 69.0% and a failure rate of 31.0%, which is slightly above the UK average of approximately 37%.
Based on this data, the Smc Quad earns a "Good" reliability rating. The average Smc Quad presents for MOT with approximately 7,217 miles on the clock. Manufacture year matters: 2005 models achieve the highest pass rate at 75.5%, while 2004 models have the lowest at 64.1%. This 11.4 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Smc Quad is Suspension, affecting 33.7% of all tests. 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. The second most common issue is Lamps, Reflectors and Electrical Equipment at 26.3%. Brakes rounds out the top three at 17.3%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

Suspension — 33.7% of failures
Suspension issues account for 33.7% of MOT failures on the Smc Quad. 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.
Lamps, Reflectors and Electrical Equipment — 26.3% of failures
Lamps, Reflectors and Electrical Equipment issues account for 26.3% of MOT failures on the Smc Quad. 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.
Brakes — 17.3% of failures
Brakes issues account for 17.3% of MOT failures on the Smc Quad. 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).
