Chery Arrizo 8 MOT failure rates: what to expect

The Chery Arrizo 8’s MOT failures most commonly involve tyre condition, brake system issues, lighting faults, and suspension wear. Testers focus on safety-critical components such as tread depth, brake efficiency, bulb operation, and suspension integrity. Owners can spot many problems early by regularly checking tyre tread and pressure, brake responsiveness and noises, all lights, and listening for unusual suspension noises or handling changes.

Tyre Condition and Tread Depth

Tyres are a frequent cause of MOT failure on the Chery Arrizo 8, primarily due to insufficient tread depth or damaged sidewalls. The MOT test requires a minimum tread depth of 1.6mm across the central three-quarters of the tyre’s breadth and around the entire circumference. Testers also look for cuts, bulges, and other visible damage that could compromise safety.

Owners can inspect their tyres visually and by feel. Running a finger along the tread grooves helps identify worn areas, while checking the sidewalls for cracks or bulges is essential. Uneven wear may indicate alignment or suspension problems. Tyre pressure should be maintained as per the manufacturer’s recommendation, as underinflated tyres wear faster and affect handling.

Repairing tyre issues usually involves replacing worn or damaged tyres with new ones that meet safety standards. If uneven wear is present, a wheel alignment or suspension check may be necessary to prevent rapid degradation of the new tyres.

Brake System Defects

Brake faults are another common MOT failure point for the Arrizo 8. The tester checks the efficiency of the braking system using a roller brake tester, ensuring the car can stop effectively and evenly on all wheels. They also inspect brake pads, discs, drums, and brake lines for wear, damage, or leaks.

Owners can detect brake problems by noting any unusual noises such as squealing or grinding when braking, a spongy or stiff brake pedal, or longer stopping distances. Visual inspection under the wheel arches can reveal worn brake pads or rusty, scored discs.

Brake repairs might involve replacing brake pads, resurfacing or replacing discs, and repairing or replacing brake lines if leaks are found. Brake fluid may also need changing if it is contaminated or has absorbed moisture, which reduces braking performance.

Lighting and Electrical Checks

Lighting faults are a frequent MOT failure cause on the Chery Arrizo 8. The MOT tester checks all exterior lights including headlights, indicators, brake lights, fog lights, and number plate illumination. Each bulb must work correctly and be the correct colour and brightness. The tester also checks that headlights are correctly aimed.

Owners should regularly check all lights for operation, replacing any blown bulbs promptly. Dirty or cracked lenses can reduce light output and should be cleaned or replaced. Headlight aim can be checked visually by comparing beam height against a wall or garage door from a set distance.

Repairs involve replacing faulty bulbs or fuses, cleaning or replacing lenses, and adjusting headlight aim using the adjustment screws or electronic controls if fitted. Electrical faults may require wiring inspection and repair if bulbs fail repeatedly or flicker.

Suspension and Steering Wear

Suspension and steering components on the Arrizo 8 often cause MOT failures due to wear or damage. The tester checks for excessive play in ball joints, track rod ends, and suspension bushes, as well as inspecting shock absorbers for leaks or poor damping performance. Steering is checked for excessive free play or binding.

Owners can notice suspension problems through uneven tyre wear, a knocking or rattling noise over bumps, or a vague or wandering steering feel. Visual inspection may reveal torn rubber boots or leaking shock absorbers.

Repairs typically involve replacing worn bushes, ball joints, or track rod ends, and renewing shock absorbers if leaking or ineffective. Steering repairs may require adjusting or replacing components to restore correct geometry and responsiveness.

Exhaust and Emissions

Exhaust system faults can also lead to MOT failure on the Arrizo 8, especially leaks, corrosion, or excessive noise. The tester checks the exhaust for leaks, secure mounting, and noise levels. Emissions are tested to ensure the engine runs cleanly within legal limits.

Owners can spot exhaust issues by listening for unusual noises such as rattling or loud exhaust sounds, or by noticing a strong smell of fumes inside or around the car. Visible rust or holes in the exhaust pipe or silencer are signs of corrosion.

Repair work may include welding or replacing sections of the exhaust pipe, fitting a new silencer, or replacing mounting brackets and hangers. If emissions fail, the cause may be engine-related and require diagnostic checks and repairs to sensors, catalytic converters, or fuel systems.

Windscreen and Wiper Condition

The MOT also checks the windscreen and wipers on the Arrizo 8, as visibility is critical for safety. The tester looks for chips or cracks in the windscreen that could impair the driver’s view, and checks that wipers and washers operate effectively.

Owners should regularly inspect the windscreen for damage and replace wiper blades if they leave streaks or miss spots. Washer fluid should be topped up to ensure the screen can be cleaned when needed.

Repairs involve replacing the windscreen if damage is severe enough to affect vision or structural integrity. Wiper blades are replaced simply by removing the old rubber inserts or entire arms. Washer jets or pumps may need repair if fluid does not spray correctly.

Regular maintenance and simple pre-MOT checks on tyres, brakes, lights, suspension, exhaust, and visibility systems can help Chery Arrizo 8 owners avoid common MOT failures. Being proactive about these safety-critical components ensures the car remains roadworthy and compliant with UK MOT standards.
