Vauxhall Nova MOT Reliability Overview
The Vauxhall Nova is a relatively common sight on UK roads, with 38,532 MOT test results recorded in our database spanning 11 manufacture years. It has an overall MOT pass rate of 57.1% and a failure rate of 42.9%, which is slightly below the UK average of approximately 37%.
Based on this data, the Vauxhall Nova earns a "Below Average" reliability rating. The average Vauxhall Nova presents for MOT with approximately 54,815 miles on the clock. Manufacture year matters: 1984 models achieve the highest pass rate at 65.6%, while 1993 models have the lowest at 53.4%. This 12.2 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Vauxhall Nova is Suspension, affecting 38.2% 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 Brakes at 28.3%. Lamps, Reflectors and Electrical Equipment rounds out the top three at 26.9%. 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 Vauxhall Nova shows a relatively stable failure rate after warranty — the change of 0% is negligible. Peak failure occurs at age 16 (55.7% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

Focus your pre-MOT checks on suspension 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 Nova is likely to perform.
Suspension — 38.2% of failures
Suspension issues account for 38.2% of MOT failures on the Vauxhall Nova. 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.
Brakes — 28.3% of failures
Brakes issues account for 28.3% of MOT failures on the Vauxhall Nova. 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 — 26.9% of failures
Lamps, Reflectors and Electrical Equipment issues account for 26.9% of MOT failures on the Vauxhall Nova. 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.
