Mitsubishi Outlander MOT failure rates: what to expect

The Mitsubishi Outlander often fails its MOT due to issues with brakes, tyres, suspension components, and lighting. Testers focus on safety-critical parts like brake efficiency, tyre condition, suspension integrity, and correct lighting operation. Owners can spot these faults early by checking brake feel, tyre wear, suspension noise or play, and all lights before the MOT test. Repairs typically involve replacing worn parts or adjusting systems to meet legal standards.

Brake System Failures

Brake problems are among the most common reasons for an Outlander to fail its MOT. The tester checks the brake efficiency on all wheels, looking for uneven braking force, excessive pedal travel, or warning lights on the dashboard. They also inspect the condition of brake pads, discs, and fluid leaks.

Owners can spot brake issues by noting any sponginess or softness in the brake pedal, unusual noises like squealing or grinding when braking, or a pulling sensation to one side. A warning light on the dash related to the braking system is a clear sign to get the brakes checked.

Repairs usually involve replacing worn brake pads and discs, which requires removing the wheel, caliper, and old pads before fitting new components and reassembling. Brake fluid may need flushing and replacing if contaminated or low. In some cases, calipers or brake lines might require attention if leaking or seized.

Tyre Condition and Tread Depth

Tyres are a key MOT check point, and the Outlander often fails due to insufficient tread depth or damage. The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre and around the entire circumference. Testers also look for sidewall damage, bulges, or uneven wear.

Owners should regularly inspect their tyres for tread wear using a tread depth gauge or a 20p coin test. Look for cracks, cuts, or bulges on the sidewalls and check for uneven wear patterns that might indicate alignment or suspension issues.

Repairing tyre-related MOT failures involves replacing any tyres that do not meet legal tread depth or show damage. Tyre replacement requires removing the wheel and fitting a new tyre, which is then balanced to avoid vibration. If uneven wear is present, a wheel alignment check and adjustment may be necessary to prevent premature tyre wear.

Suspension and Steering Components

The Outlander’s suspension and steering are scrutinised during the MOT for worn or damaged parts that affect vehicle control and safety. Testers check for excessive play in ball joints, track rod ends, and wishbones, as well as the condition of shock absorbers and springs.

Owners can detect suspension faults by listening for clunks or rattles over bumps, feeling excessive body roll or instability when cornering, or noticing uneven tyre wear. Steering play or difficulty in handling can also indicate worn components.

Repairs involve replacing worn bushes, ball joints, or track rod ends, which requires lifting the vehicle, removing the affected parts, and fitting new ones. Shock absorbers and springs may also need replacement if leaking or broken. After suspension work, a wheel alignment is often necessary to restore proper handling.

Lighting and Electrical Checks

Lighting faults are a frequent cause of MOT failure on the Mitsubishi Outlander. Testers ensure all lights work correctly, including headlights, brake lights, indicators, fog lights, and the number plate illumination. They also check for correct beam alignment and the presence of any warning lights on the dashboard.

Owners should carry out a simple walk-around before the MOT, switching on all lights and checking their operation and brightness. Look for cracked or fogged lenses and ensure bulbs are the correct type and securely fitted.

Fixing lighting issues usually involves replacing blown bulbs, repairing wiring faults, or adjusting headlight aim. Lens repairs or replacements may be needed if damaged. Electrical diagnostics might be required if warning lights indicate faults in the vehicle’s lighting control systems.

Exhaust and Emissions

While less common than brakes or tyres, exhaust system faults can cause an Outlander to fail its MOT. Testers check for leaks, excessive noise, and emissions compliance. The exhaust must be securely mounted and free from holes or corrosion that could allow fumes to escape.

Owners can listen for unusual exhaust noises such as rattling or loud rumbling, and visually inspect the exhaust pipe and silencer for rust or holes. A strong smell of exhaust fumes inside the cabin is a serious warning sign.

Repairs involve replacing corroded or damaged sections of the exhaust system, which requires removing the faulty parts and fitting new pipes or silencers. Exhaust mounts or hangers may also need replacing to secure the system properly.

Windscreen and Wipers

The condition of the windscreen and wipers is another MOT check area where the Outlander can fail. Testers look for chips or cracks in the driver’s line of sight that could impair vision, as well as the effectiveness of the wiper blades and the operation of the washer system.

Owners should inspect the windscreen for any damage, especially in the area directly in front of the driver, and replace wiper blades if they leave streaks or miss spots. Check that the washer jets spray fluid correctly.

Repairs may involve replacing the windscreen if damage is severe or in a critical area. Wiper blade replacement is straightforward, requiring removal of the old blades and fitting new ones. Washer system repairs might include topping up fluid or fixing blocked jets or faulty pumps.
