TL;DR
The MG HS has common MOT failure categories including brakes, suspension, lighting, and emissions. Understanding these issues can help you prepare for potential repairs. Failure rates increase significantly after five years, with repair costs varying widely based on the issue.
Common Failure Categories
The MG HS faces several common failure categories during its MOT tests. Brakes are often the leading cause of failure, with issues ranging from worn brake pads to serious braking system problems. Suspension faults are prevalent, particularly in older models, where components may wear out over time. Lighting issues frequently arise, with faulty bulbs or wiring leading to failures, but these are typically easy and inexpensive to fix. Emissions failures are another concern, especially as vehicles age and components degrade.
Age-by-Age Fail Rates
MOT failure rates for the MG HS tend to rise with age. Newer models, particularly those under three years old, generally pass without issues. However, vehicles over five years old see a marked increase in failure rates due to natural wear and tear on components like brakes and suspension.

Suspension repairs can also be costly, often ranging from £200 to £600. Lighting repairs are typically the least expensive, costing around £20 to £50 for bulb replacements. Emissions repairs can be complex, ranging from £100 to over £500, depending on the specific issue. Structural repairs, if needed, can exceed £500, making it essential to address potential issues early.
Quick Fixes vs Structural Issues
Many common MOT failures on the MG HS are quick fixes. Replacing a bulb or adjusting a brake light can often be done in under an hour and for a modest cost.
