Toyota Yaris MOT failure rates: what fails, what to fix

TL;DR

The Toyota Yaris is known for its reliability but can face common MOT failures, particularly with brakes, suspension, lighting, and emissions. Fail rates increase with age, and repair costs vary, with brake repairs typically ranging from £100 to £300. Regular maintenance can help mitigate issues.

Common MOT Failures

The most frequent MOT failures for the Toyota Yaris include issues with brakes, suspension, lighting, and emissions. Brakes often fail due to worn pads or discs, while suspension failures can arise from worn shock absorbers or bushings. Lighting failures typically involve blown bulbs or faulty wiring, which are relatively easy and inexpensive to fix. Emissions issues can also occur, particularly if the vehicle has not been regularly serviced, leading to increased pollution levels and potential fines.

Age-Related Fail Rates

Fail rates for the Yaris tend to rise with age. For example, around 30% of Yaris vehicles fail their MOT at five years old. This rate can increase to over 40% by the time the vehicle reaches ten years. Regular maintenance can help mitigate some of these issues, but age-related wear is inevitable. Owners should be aware that as the car ages, components such as the exhaust system and fuel injectors may also require attention, contributing to the overall failure rate.

Cost of Repairs

Repair costs for common MOT failures can vary widely. Brake repairs can range from £100 to £300, depending on the extent of the work needed. Lighting issues are usually cheaper to fix, costing between £50 and £150. Suspension repairs can also be costly, often falling in the £150 to £400 range, especially if multiple components need replacement. Additionally, addressing emissions-related issues can be expensive, particularly if the catalytic converter needs replacement, which can cost upwards of £500.

Quick Fixes vs Structural Issues

Many issues are quick fixes, such as replacing bulbs or brake pads. However, structural problems, like rust in the chassis, can be more serious and costly. Owners of older Yaris models should inspect for rust regularly, as repairs for structural issues can run into the hundreds or even thousands of pounds. It is also advisable to check for any signs of corrosion on the wheel arches and underbody, as these areas are particularly vulnerable.

The 1.0 VVT-i engine of the Toyota Yaris often develops problems with the VVT-i system after around 60,000 km. This can lead to rough idling and a noticeable loss of power. The valve timing may not switch properly between different camshaft positions, resulting in increased fuel consumption and reduced exhaust emissions.
