The Subaru Outback is generally a reliable vehicle, but like any car, it can encounter issues that may lead to an MOT failure. Common problems include suspension wear, emissions failures, and brake system issues. Fixing these problems can vary in cost, but being aware of them can help you prepare for your next MOT.

Suspension Problems

One of the most frequent causes of MOT failure for the Subaru Outback is suspension wear. Components such as shock absorbers, struts, and bushings can degrade over time, leading to a bumpy ride and compromised handling.

Regular checks can help identify these issues before they lead to an MOT failure.

Emissions Failures

Emissions-related failures are also common in the Subaru Outback. The vehicle’s exhaust system, including the catalytic converter and oxygen sensors, can fail to meet UK emissions standards.

Keeping an eye on warning lights and having regular emissions checks can help prevent these failures.

Brake System Issues

The brake system is crucial for safety, and any issues here can lead to an MOT failure. Common problems include worn brake pads, damaged discs, or leaks in the brake lines.

Regular maintenance of the brake system is essential to ensure safety and pass the MOT.

Tyre Condition

Tyres are another common area where the Subaru Outback can fail its MOT. Issues such as tread depth below the legal limit or uneven wear can lead to a failure.

In the UK, the minimum tread depth is 1.6mm across the central three-quarters of the tyre. Regularly checking tyre pressure and tread depth can help you avoid unexpected failures.

Lighting and Electrical Systems

Lighting and electrical issues can also cause MOT failures in the Subaru Outback. Problems may include faulty bulbs, damaged wiring, or issues with the battery and alternator.

Regular checks of all lights and electrical components can help catch these issues early.

Bodywork and Structural Integrity

Finally, the condition of the bodywork and structural integrity of the Subaru Outback can lead to MOT failures. Rust, corrosion, or damage to the chassis can be problematic.

Keeping the vehicle clean and regularly inspecting for signs of rust can help maintain its structural integrity and pass the MOT.

By staying informed about these common issues and their associated costs, you can better prepare your Subaru Outback for its next MOT and avoid unexpected expenses. Regular maintenance and timely repairs can ensure your vehicle remains reliable and roadworthy.
