McLaren Artura MOT failure rates: what to expect

The McLaren Artura’s MOT failures most commonly involve tyre condition, brake system wear, and lighting faults. Testers focus on safety-critical components like tread depth, brake efficiency, and correct light operation. Owners can pre-empt these issues by regular visual checks, listening for unusual noises, and ensuring all lights function properly before the test.

Tyre Condition and Tread Depth

Tyres are a frequent cause of MOT failure on the McLaren Artura, as with many performance cars. The MOT tester checks for minimum tread depth, damage, and correct type and size for the vehicle. The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre and around the entire circumference.

Owners should inspect their tyres regularly for uneven wear, cuts, bulges, or embedded objects. Performance tyres on the Artura can wear unevenly due to the car’s power and handling characteristics, so it’s important to monitor tread depth across the whole surface, not just the centre.

If tyres fail the MOT, replacement involves removing the wheel and fitting new tyres of the correct specification. The wheels are balanced to avoid vibrations, and the tyre pressures are adjusted to manufacturer recommendations. A wheel alignment check may also be advisable to prevent premature wear on new tyres.

Brake System Wear and Efficiency

The MOT test rigorously examines the braking system, including pads, discs, and fluid condition. The tester measures brake efficiency to ensure the car can stop safely under normal conditions. Worn brake pads or scored discs are common failure points on the Artura, especially given its high-performance braking demands.

Owners can spot brake issues by listening for squealing or grinding noises when applying the brakes, feeling for vibrations through the pedal, or noticing longer stopping distances. Visual checks through the alloy wheels can reveal pad thickness and disc condition, though some inspection may require wheel removal.

Repair involves replacing worn brake pads and, if necessary, resurfacing or replacing brake discs. Brake fluid may also need flushing if it has absorbed moisture, which reduces braking performance. The work requires careful bleeding of the system to remove air and restore pedal firmness.

Lighting and Electrical Checks

Lighting faults are another common MOT failure area for the McLaren Artura. The test checks all exterior lights, including headlights, indicators, brake lights, and number plate illumination, for correct operation, brightness, and alignment.

Owners should walk around the car before the MOT, activating each light to ensure it works. Bulbs can fail or connections become corroded, especially in the rear light clusters. Misaligned headlights can also cause failure, as they must illuminate the road correctly without dazzling other drivers.

Fixing lighting faults usually involves replacing bulbs or fuses, cleaning contacts, or adjusting headlight aim. Some electrical issues may require diagnostic checks to identify wiring faults or control module problems. Ensuring all lights function properly before the MOT saves time and hassle.

Suspension and Steering Components

The MOT tester examines suspension and steering parts for excessive wear, damage, or play that could affect vehicle control. On the Artura, the sophisticated suspension setup may be prone to wear in bushes, ball joints, or dampers due to the car’s dynamic use.

Owners can detect suspension issues by noticing unusual noises over bumps, uneven tyre wear, or a loose or wandering steering feel. Visual inspection can reveal leaking dampers or damaged rubber bushes, but some wear may only be apparent during a test drive or professional inspection.

Repairs can include replacing worn bushes, ball joints, or shock absorbers. This work often involves removing wheels and suspension arms to access components. After replacement, wheel alignment is essential to restore proper handling and tyre wear.

Exhaust Emissions and Noise Levels

The MOT also checks exhaust emissions and noise levels to ensure the vehicle meets environmental and safety standards. The Artura’s hybrid powertrain and performance exhaust system can sometimes cause issues if components are damaged or modified.

Owners should listen for unusual exhaust noises such as rattles or excessive loudness, which may indicate leaks or broken mounts. Emissions problems can arise from faulty sensors or catalytic converters.

Repairing exhaust faults involves locating and fixing leaks, replacing damaged sections, or restoring mounts and hangers. Emission-related repairs may require sensor replacement or cleaning catalytic components. Ensuring the exhaust system is intact and functioning properly helps pass the MOT emissions test.

Windscreen and Visibility Checks

Visibility is crucial for safety, so the MOT includes checks on the windscreen and wipers. The tester looks for chips or cracks in the driver’s view area that could impair vision, as well as the condition and operation of wipers and washers.

Owners should inspect the windscreen for damage, especially in the driver’s line of sight. Wiper blades should clear the screen effectively without streaking or leaving patches. Washer fluid levels must be topped up to ensure the screen can be cleaned during the test.

Repairing visibility issues may involve stone chip repair or windscreen replacement if damage is severe. Wiper blades are replaced by removing the old blades and fitting new ones compatible with the Artura’s arms. Washer system faults require checking pumps, hoses, and nozzles for blockages or leaks.

By proactively checking tyres, brakes, lights, suspension, exhaust, and visibility systems, McLaren Artura owners can reduce the risk of MOT failure. Regular maintenance and attention to these common trouble spots ensure the car remains safe, roadworthy, and ready for the test.
