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

The Mitsubishi Shogun often faces specific issues during its MOT tests, with common failures including suspension components, emissions, and brakes. Typical repair costs can vary, but addressing these problems promptly can help ensure your vehicle passes its MOT and remains roadworthy.
Suspension Issues
One of the most frequent causes of MOT failures for the Mitsubishi Shogun is worn suspension components. This can include issues with shock absorbers, bushings, and ball joints. If these parts are found to be leaking or excessively worn, they will need to be replaced.
Repairing suspension components can be costly, with shock absorber replacement typically ranging from £150 to £300 per pair, depending on the parts used and labour costs. Bushings and ball joints can add an additional £100 to £200 to the overall repair bill. Regular checks can help catch these issues early, potentially saving money in the long run.
Emissions Failures
Emissions tests are a critical part of the MOT, and the Mitsubishi Shogun can sometimes struggle to meet the required standards. Common problems include faulty catalytic converters or issues with the exhaust system. If the vehicle emits excessive pollutants, it will fail the MOT.
Replacing a catalytic converter can be quite expensive, often costing between £500 and £1,200, depending on the model and parts used. Additionally, if there are leaks or damage in the exhaust system, repairs can range from £100 to £400. Keeping the engine well-maintained and using quality fuel can help reduce emissions and improve performance.
Brake System Problems
The brakes are vital for safety, and any issues can lead to an MOT failure. Common problems include worn brake pads, discs, and issues with the brake lines. If the brake system does not perform adequately during testing, it will need immediate attention.
Replacing brake pads typically costs between £100 and £250, while brake disc replacement can add another £150 to £300. If there are issues with the brake lines, repairs may range from £50 to £150, depending on the extent of the damage. Regular brake inspections can help identify problems before they become serious.
Tyre Condition
Tyres are a crucial aspect of vehicle safety, and the Mitsubishi Shogun is no exception. MOT testers check for tread depth, uneven wear, and sidewall damage. If any of these issues are present, the vehicle will fail the test.
The cost of replacing tyres can vary significantly based on brand and size, but expect to pay between £80 and £150 per tyre. Regularly checking tyre pressure and tread depth can help prolong their life and ensure they meet MOT requirements. Additionally, rotating tyres can help prevent uneven wear.
Lighting and Electrical Failures
Lighting and electrical systems are frequently checked during the MOT. Common issues include faulty bulbs, damaged wiring, or malfunctioning indicators. A failure in these systems can lead to a failed MOT, as they are essential for safe driving.
Replacing bulbs is generally inexpensive, costing around £10 to £30 for parts and labour. However, if there are more extensive electrical issues, repairs can range from £50 to £200, depending on the complexity of the problem. Regularly inspecting lights and electrical components can help prevent failures during the MOT.
Bodywork and Structural Integrity
While not as common as mechanical failures, bodywork and structural issues can also lead to an MOT failure. This can include rust, corrosion, or damage to the chassis. If these problems are severe, they may compromise the vehicle’s safety.
Repairing bodywork can be quite variable in cost, with minor rust repairs costing around £100 to £300, while more extensive structural repairs can exceed £1,000. Regular maintenance and addressing any signs of rust early can help prevent costly repairs and ensure the vehicle remains safe and roadworthy.
