Common MOT Failure Categories
The MG MG4 often faces failures in specific categories. Brakes are a frequent issue, particularly with wear and tear on pads and discs. Suspension problems, such as worn bushings or shock absorbers, also contribute significantly to failure rates. Lighting failures, often due to blown bulbs, are common but relatively easy to fix. Emissions failures can occur due to issues with the exhaust system or engine management.
Age-by-Age Fail Rate Trajectory
As the MG MG4 ages, its MOT fail rate tends to increase. Newer models (up to three years old) show a low fail rate, often below 10%. However, as vehicles reach five to seven years, the fail rate can rise to over 20%. This trend highlights the importance of regular maintenance and checks as the vehicle ages.
Quick Fixes vs Structural Issues
Many MOT failures can be resolved with quick fixes. Replacing bulbs or adjusting brakes can often be done for minimal cost. However, structural issues, such as those affecting the suspension or chassis, can be more complex and expensive to repair. Owners should be aware of these potential pitfalls when considering the MG MG4.
Cost Ranges for Typical Failures
Repair costs for common MOT failures vary. Simple fixes like bulb replacements can cost around £20. More significant repairs, such as brake pad replacements, can range from £150 to £300. Suspension repairs may also fall within this range but can exceed £300 depending on the severity of the issue. Being prepared for these costs can help owners maintain their vehicles effectively.
