Toyota Corolla MOT failure rates: what fails, what to fix
What the DVSA MOT data shows for the Toyota Corolla. The most common failure categories and what each one typically costs to put right.
Toyota Corolla MOT failure rates show a pattern of common issues that owners should be aware of. Understanding these can help in maintaining the vehicle and preparing for the annual MOT test.
Common MOT Failure Categories
The Toyota Corolla frequently fails MOT tests due to issues with brakes, suspension, lighting, and emissions. Brakes are often the most common failure point, with problems ranging from worn pads to faulty discs. Suspension issues, such as worn shock absorbers, also appear regularly, particularly in older models.
Age-by-Age Fail Rate Trajectory
MOT failure rates tend to increase as the vehicle ages. For Corollas aged 0-3 years, the failure rate is typically low, often below 10%. However, as the car reaches the 10-15 year mark, the fail rate can rise to 30% or higher, largely due to wear and tear on components.
Quick Fixes vs Structural Issues
Many MOT failures can be addressed with quick fixes. Issues like blown bulbs or minor brake adjustments are usually straightforward and inexpensive. In contrast, structural problems, such as rust on the chassis or significant bodywork damage, can lead to costly repairs, sometimes exceeding £1000.
Typical Repair Costs
Repair costs for common MOT failures can vary widely. For brake issues, you might expect to pay between £150 and £400. Suspension repairs can range from £100 to £500, while fixing lighting problems could cost around £50 to £150. Emissions repairs can be more expensive, often falling between £200 and £800, depending on the severity of the issue.
