The steering system is one of the most safety-critical components of any vehicle. Even minor wear can affect handling, control, and driver confidence. In the UK, steering-related faults are a common reason for MOT advisories and failures, particularly as vehicles age. Understanding how steering system wear impacts MOT failure rates can help drivers address issues before their test.
The MOT test ensures vehicles meet minimum road safety standards, and steering components are closely inspected. Any excessive wear, looseness, or damage can result in a major defect and an immediate failure. Because steering directly affects a driver’s ability to control the vehicle, MOT rules are strict in this area.
Wear often develops gradually, meaning drivers may adapt without realising there is a problem until it appears during an MOT inspection.
Several steering system parts are prone to wear over time. Track rod ends and ball joints are among the most frequent causes of MOT advisories and failures due to excessive play. Steering racks can also develop leaks or internal wear, particularly on higher-mileage vehicles.
Power steering issues, such as fluid leaks or malfunctioning pumps, are also checked. Any fault that compromises steering assistance or causes inconsistent response can result in an MOT failure.
Drivers often notice warning signs before steering problems become severe. Knocking noises when turning, vague or loose steering feel, uneven tyre wear, and steering wheel vibration can all indicate worn components.
Ignoring these symptoms increases the likelihood of an MOT failure. Addressing steering wear early not only improves safety but can reduce repair costs compared to fixing multiple worn parts after a failed test.
Steering faults contribute significantly to MOT failure statistics, particularly for older vehicles. Components exposed to road conditions, such as potholes and speed bumps, wear faster in urban areas. Vehicles with neglected maintenance or poor wheel alignment are especially vulnerable.
Checking a car’s MOT history can reveal recurring steering advisories, which often point to underlying issues. Tools such as the MOT history checker on CheckMot.com help drivers identify patterns and take preventative action before their next test.
Regular servicing is the most effective way to reduce steering-related MOT failures. Having suspension and steering components inspected annually allows worn parts to be replaced before they become dangerous.
Wheel alignment checks, prompt repair of leaks, and addressing unusual handling behaviour all help maintain steering performance. Preventative maintenance not only improves MOT pass rates but also enhances overall driving safety.
Yes. Excessive play, leaks, or damage to steering components will result in an MOT failure.
Not always. Steering wear can develop gradually and may only be detected during an MOT inspection.
Yes. Significant leaks or reduced steering assistance can lead to an MOT failure.
It’s recommended to have them inspected during annual servicing or whenever handling feels unusual.
Yes. Past advisories and failures often highlight recurring steering-related issues.
