About This Data
The 1991 Nissan Auto has an MOT pass rate of 39.0% based on 41 tests — significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 88,443 miles on the odometer. With a 61.0% failure rate, the 1991 Auto is rated as "Very Poor" for MOT reliability.
If you own or are considering buying a 1991 Nissan Auto, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to tyres: 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. With an average mileage of 88,443 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Tyres — 19.5% of failures
Tyres issues account for 19.5% of MOT failures on 1991 Nissan Auto models. 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.
Noise, emissions and leaks — 12.2% of failures
Noise, emissions and leaks issues account for 12.2% of MOT failures on 1991 Nissan Auto models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
Suspension — 12.2% of failures
Suspension issues account for 12.2% of MOT failures on 1991 Nissan Auto models. 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.
