Ford Fiesta MOT failure rates: what fails, what to fix

The Ford Fiesta is a popular choice among UK drivers. Understanding its MOT failure rates can help owners maintain their vehicles and avoid costly repairs.

Common Failure Categories

The Ford Fiesta often fails its MOT in several key areas. Brakes are the most frequent issue, with worn pads and discs being common culprits. Suspension problems, including worn shock absorbers and springs, are also prevalent. Lighting failures, such as non-functioning headlights or indicators, are easy to fix but can lead to MOT failure if overlooked. Emissions issues are more common in older models, especially those registered before 2015.

Age-by-Age Failure Rates

MOT failure rates generally increase as the Fiesta ages. Models from 2008 to 2012 tend to have higher failure rates, often exceeding 30%. In comparison, newer models (2018 onwards) usually see failure rates below 10%. This trend highlights the importance of regular maintenance and timely repairs to keep older Fiestas roadworthy.

Quick Fixes vs Structural Issues

Many common MOT failures can be resolved with quick fixes. Replacing a blown bulb or adjusting headlights can often be done for under £50. However, structural issues, such as corrosion or significant suspension damage, can be costly to repair. Addressing these problems early can prevent more extensive damage and higher repair costs down the line.

Typical Repair Costs

Repair costs for common MOT failures vary significantly. Minor issues like lighting or wiper blade replacements can cost around £50. Brake repairs may range from £150 to £500, depending on the extent of the wear. Suspension repairs can be more expensive, often exceeding £500 for parts and labour. Owners should budget for these potential costs to keep their Fiesta in good condition.
