XPeng G6 MOT failure rates: what to expect

The XPeng G6’s most common MOT failures relate to tyre condition, brake performance, lighting faults, and windscreen damage. Testers focus on legal tread depth, brake efficiency, correct operation and alignment of lights, and windscreen chips or cracks. Owners can spot these issues early by regular visual checks and simple functional tests, preventing MOT failure and ensuring safe driving.

Tyre Condition and Tread Depth

Tyres are the most frequent cause of MOT failure on the XPeng G6, primarily due to worn tread or damage. The MOT requires a minimum tread depth of 1.6mm across the central three-quarters of the tyre and around the entire circumference. Testers also check for any cuts, bulges, or other visible damage.

Owners should regularly inspect their tyres for signs of wear, uneven tread, or sidewall damage. Uneven wear can indicate alignment or suspension issues, which also affect safety. Checking tread depth can be done with a simple gauge or by using the tread wear indicators moulded into the tyre. If the tread is close to the legal limit, replacement is necessary before the MOT.

Repairing tyre issues involves fitting new tyres or, if damage is minor and repairable, patching or plugging the affected area. Tyre replacement requires removing the wheel, dismantling the tyre from the rim, fitting a new tyre, and balancing the wheel to ensure smooth running. Proper tyre maintenance not only helps pass the MOT but also improves handling and efficiency.

Brake System Performance

Brake faults are another common MOT failure point for the XPeng G6. The tester checks the braking efficiency on each wheel, looking for uneven braking, excessive pedal travel, or warning lights on the dashboard. Brake pads, discs, and fluid condition are also assessed.

Owners can detect brake issues by noting any unusual noises such as squealing or grinding, a spongy or stiff brake pedal, or a warning light illuminating on the dash. Reduced braking performance or pulling to one side when braking suggests a problem.

Brake repairs can range from replacing worn brake pads and discs to bleeding the brake fluid to remove air bubbles or contaminants. In some cases, calipers may need servicing or replacement if they are sticking or leaking. Brake fluid replacement involves flushing the old fluid and refilling with fresh fluid to maintain hydraulic pressure and safety.

Lighting and Electrical Checks

Lighting faults are a frequent MOT failure cause on the XPeng G6, including non-functioning bulbs, incorrect aim, or damaged lenses. The MOT tester checks all exterior lights such as headlights, indicators, brake lights, and number plate illumination for correct operation and alignment.

Owners should regularly test all lights before driving, replacing any burnt-out bulbs promptly. Checking that headlights are correctly aimed is important to avoid dazzling other road users or poor road illumination. Damaged or cracked lenses can also cause failure as they may reduce light output or allow moisture ingress.

Repairs involve replacing bulbs, adjusting headlight aim using the adjustment screws, or replacing damaged lenses or entire light units if necessary. Electrical faults may require checking fuses, wiring, or connectors for corrosion or damage to restore proper function.

Windscreen and Visibility

The XPeng G6 often fails the MOT due to windscreen damage such as chips or cracks in the driver’s line of sight. The MOT rules specify that any damage within a critical area of the windscreen that could obscure the driver’s view will cause failure.

Owners should inspect the windscreen regularly for chips or cracks, especially after driving on gravel roads or through debris. Even small chips can spread quickly and compromise visibility.

Repairing windscreen damage involves either filling chips with resin to prevent spreading or replacing the entire windscreen if the damage is too extensive. Windscreen replacement requires removing the old glass carefully and resealing the frame to maintain structural integrity and weatherproofing.

Suspension and Steering Components

Suspension and steering faults can also lead to MOT failure on the XPeng G6, as these affect vehicle control and safety. The MOT tester checks for worn or damaged suspension bushes, shock absorbers, ball joints, and steering linkages. Excessive play or leaks in shock absorbers are common issues.

Owners may notice symptoms such as uneven tyre wear, knocking noises over bumps, or poor handling and steering response. Visual inspection can reveal leaking shocks or damaged rubber bushes.

Repairs involve replacing worn suspension bushes, shock absorbers, or steering components. This work requires lifting the vehicle, removing the affected parts, and fitting new components to restore proper suspension geometry and ride quality.

Wiper Blades and Washer System

While less common, MOT failures on the XPeng G6 can occur due to defective wiper blades or washer systems. Testers check that the windscreen wipers operate correctly and clear the screen effectively, and that the washer fluid sprays adequately.

Owners should check wiper blades for cracks, splits, or stiff rubber that reduces wiping efficiency. The washer reservoir should be topped up and the jets aimed correctly.

Replacing wiper blades is a straightforward task involving unclipping the old blades and fitting new ones. Washer jets can be cleaned or adjusted to improve spray pattern. Maintaining these systems ensures good visibility in wet weather and helps pass the MOT.

Regular checks on tyres, brakes, lights, windscreens, suspension, and visibility systems can help XPeng G6 owners avoid common MOT failures. Early detection and timely repairs keep the vehicle safe and roadworthy, making the MOT process smoother and less stressful.
