What the DVSA MOT data shows for the Mercedes-Benz GLA. The most common failure categories and what each one typically costs to put right.
The Mercedes-Benz GLA has specific patterns in MOT failures. Understanding these can help you address potential issues before your next test.
Brakes and suspension are the top failure categories.

Common MOT Failure Categories
The most frequent reasons for a Mercedes-Benz GLA failing its MOT include brakes, suspension, lighting, and emissions. Brakes are particularly critical, with issues often arising from worn pads or discs. Suspension problems, such as worn shock absorbers, also contribute significantly to failure rates.
Age-by-Age Failure Rate Trajectory
MOT failure rates tend to increase as the vehicle ages. For the GLA, models from 2014 to 2018 have shown higher failure rates, particularly in brake and suspension categories. Vehicles over five years old often require more frequent repairs and checks.
Quick Fixes vs Structural Issues
Many failures can be addressed with straightforward fixes, such as replacing bulbs or brake pads. However, some structural issues may arise, particularly with suspension components. These can be more costly and time-consuming to repair.
Cost Ranges for Typical Failures
Typical costs for common MOT failures vary. Brake repairs can range from £100 to £400, depending on the extent of the work needed. Suspension repairs generally fall between £150 and £600. Lighting repairs are usually less expensive, often around £50 to £150.
Importance of Regular Maintenance
Regular maintenance is vital for preventing MOT failures. Routine checks on brakes, suspension, and lighting can help identify issues early. Keeping the GLA in good condition not only aids in passing the MOT but also enhances overall safety and performance.
