Subaru XV MOT failure rates: what to expect
What fails on a Subaru XV at MOT, how often, and what each fix typically costs.

The Subaru XV often faces issues during its MOT, with the most frequent failures being related to suspension components, emissions, and lighting. Typical repair costs can vary, but addressing these common problems promptly can help ensure your vehicle passes its MOT with minimal hassle.
Suspension Problems
One of the most common reasons for Subaru XV failing its MOT is suspension-related issues. Components such as shock absorbers and bushings can wear out over time, leading to a bumpy ride and reduced handling. If these parts are found to be defective, they will need to be replaced.
Replacing shock absorbers typically costs between £300 and £500, depending on whether you choose OEM or aftermarket parts. Additionally, worn bushings can lead to further suspension problems if not addressed, with replacement costs ranging from £100 to £300. Regular inspections can help catch these issues early, potentially saving you money in the long run.
Emissions Failures
Emissions testing is a critical part of the MOT process, and the Subaru XV can sometimes struggle to meet the required standards. Common culprits include a faulty catalytic converter or issues with the exhaust system. If your vehicle emits excessive pollutants, it will likely fail the test.
Repairing or replacing a catalytic converter can be quite costly, with prices typically ranging from £600 to £1,200. If the exhaust system is the issue, repairs may be more affordable, generally costing between £150 and £400. Keeping up with regular servicing can help maintain your emissions system and prevent costly repairs.
Lighting Failures
Lighting issues are another frequent reason for Subaru XV MOT failures. This includes problems with headlights, brake lights, and indicators. Faulty bulbs, corroded connections, or misaligned headlights can all lead to a failed test.
Replacing a blown bulb is usually a straightforward and inexpensive fix, costing around £10 to £20. However, if the issue lies with the wiring or the headlight assembly, costs can escalate to £100 or more. Regularly checking your lights can help ensure they are functioning correctly before your MOT.
Brake System Issues
The brake system is crucial for safety, and any faults can result in an MOT failure. Common problems include worn brake pads, discs, or issues with the brake lines. If your brakes are not performing adequately, it is essential to address these issues promptly.
Replacing brake pads typically costs between £100 and £300, while disc replacement can range from £150 to £400. If there are issues with the brake lines, repairs may cost between £100 and £200. Regular brake inspections and maintenance can help ensure your Subaru XV remains roadworthy.
Tyre Condition
Tyres are vital for safety and performance, and their condition is closely scrutinised during the MOT. Common issues include insufficient tread depth, uneven wear, or damage to the sidewalls. If your tyres do not meet the legal requirements, your vehicle will fail the test.
Replacing tyres can be a significant expense, with costs typically ranging from £50 to £150 per tyre, depending on the brand and size. Regularly checking your tyre pressure and tread depth can help you identify issues early, allowing you to replace them before your MOT.
Steering and Alignment Issues
Steering and alignment problems can also lead to MOT failures for the Subaru XV. Symptoms may include a steering wheel that is off-centre, excessive play in the steering, or unusual noises when turning. These issues can affect handling and safety.
Repairing steering components can vary in cost, with minor adjustments costing around £50 to £100. However, if parts such as the steering rack or tie rods need replacement, costs can rise to £300 or more. Regular alignment checks can help maintain proper steering and prevent more serious issues from developing.
