Is your MOT coming up again? No one wants to hear that their car has failed its MOT test, but the truth is, it's a common occurrence. In fact, a recent study from the RAC found that around 7.3 million vehicles on the road fail their MOT each year.

The MOT test is an important safety measure that checks whether your car meets the minimum safety standards. In this blog post, we will discuss the most common MOT fails, why they occur, and how you can avoid them to ensure that your car passes its MOT test with ease.

Lights and Signals

 One of the most common MOT fails is due to faulty lights and signals, with 18.9% of MOT failures relating to light issues. The most common faults are blown bulbs, damaged lenses, and wiring problems. These faults are easily detectable, and you can avoid them by carrying out regular checks on your car's lights and signals.

Replace any blown bulbs as soon as you identify they are no longer working to avoid failure during your MOT test.

Tyres

Your tyres are the difference between stopping in time, or not, so it’s vital to check them regularly.

It's important to know that tyres with cuts, cracks, or bulges are not safe to drive on. To avoid tyre-related faults, regularly check the condition of your car's tyres and ensure that they are properly inflated and have adequate tread depth and replace your tyres if they are too worn or damaged.

Brakes

Brake-related faults are extremely dangerous and need to be addressed immediately. The most common brake-related faults are worn brake pads, damaged discs or drums, and leaking brake fluid. To avoid them, it's crucial to have your brakes checked and serviced regularly.

Suspension

Faulty suspension can affect your car's stability, handling, and braking performance. The most common suspension-related faults are worn shock absorbers, broken springs, and damaged suspension joints. To avoid suspension-related faults, it's important to have your car's suspension inspected regularly during your next service and replace any worn or damaged parts promptly.

Exhaust

Faulty exhausts are not just noisy, but they also release harmful emissions that are hazardous to the environment. 7% of MOTs are failed due to problems with exhaust systems. The most common exhaust-related faults are leaks, corrosion, and damage to the catalytic converter. To avoid these faults, regularly inspect your car's exhaust system and replace any worn or damaged parts.

By carrying out regular checks and maintenance on your car's lights, tyres, brakes, suspension, and exhaust, you can avoid the most common MOT fails. If you're unsure how to maintain your car and keep it in top condition, consult a trusted mechanic or car specialist. Remember, a well-maintained car not only passes its MOT test, but it also ensures your safety and the safety of others on the road.
