Ford Mondeo MOT failure rates: what fails, what to fix
What the DVSA MOT data shows for the Ford Mondeo. The most common failure categories and what each one typically costs to put right.

TL;DR
Ford Mondeo owners should be aware of common MOT failure patterns, including issues with brakes, suspension, lighting, and emissions. Repair costs can range from £150 to £500, depending on the issue. Regular maintenance is crucial, especially for older models, to avoid costly repairs and ensure safety.
Common MOT Failure Categories
The Ford Mondeo frequently fails MOTs due to issues with brakes, suspension, lighting, and emissions. Brake problems often arise from worn pads or discs, leading to decreased stopping power. Suspension failures can include issues with shock absorbers or bushings, impacting ride comfort and handling. Lighting failures typically involve blown bulbs or faulty wiring, which are essential for safety.
Age-by-Age Failure Rates
As Mondeos age, their failure rates increase. Models from 2015 and later have a lower failure rate, often below 20%. However, those from 2010-2014 may see failure rates rise to around 30%. Vehicles older than 2010 often exceed 40% failure rates, primarily due to wear and tear. This trend highlights the importance of regular maintenance and inspections, especially for older models.
Quick Fixes vs Structural Issues
Many minor failures can be resolved quickly and cheaply. Replacing bulbs or adjusting headlight alignment is often straightforward and can be done at home. However, structural issues like rust or corrosion, particularly in older models, can lead to costly repairs. These problems may require significant work to ensure the vehicle meets safety standards, including welding or replacing parts of the chassis.
Cost Ranges for Typical Failures
Repair costs vary by issue. Brake repairs can range from £150 to £300, depending on whether pads or discs need replacing. Suspension repairs typically range from £200 to £500, depending on the extent of the damage. Lighting repairs are often less than £100, while emissions issues can vary widely based on the specific fault and may require more extensive diagnostics.
