Top 5 reasons for MOT failure

The most common reasons for an MOT retest

If your annual MOT is looming, you’ll want to ensure the risks of an MOT failure are reduced. This could potentially save you the expenditure of a retest due to something fairly simple that could have been rectified before the initial test. If your car is properly maintained and kept in a good, road-worthy condition, your car MOT shouldn’t have you worried.

The Vehicle Operator and Services Agency (VOSA) has revealed that roughly 40% of cars fail their first test. The most common MOT failure reasons are:

  • 1)Lamps, reflectors and electrical equipment
  • 2)Suspension
  • 3)Brakes
  • 4)View of the road
  • 5)Tyres

Lamps, reflectors and electrical equipment are the most common reasons for MOT failure every year, accounting for around 20% of the total. Although many people will check obvious lights around the car such as indicators and brake lights, many are caught out by headlight aim and the lights for the rear number plate, which are easily forgotten. If your lenses are looking misted, they can be easily cleaned with a specially designed, quick and affordable kit.

The suspension system is an area within all cars which is becoming an increasingly common MOT failure reason. Car manufacturers spend vast amounts of time and effort improving the handing and comfort of their vehicles, which has resulted in suspension systems becoming complex due to a number of quickly wearing parts. If you start to notice any knocks or bangs while driving it is likely there is an issue with the suspension.

Brakes are one of the most vital safety aspects of a vehicle, so it is no surprise that they are a common issue when it comes to MOT failure. Excessive or unusual wear to pads and disks are a common cause for failure, although many cars also fail because of poorly adjusted handbrakes. You will notice a reduction in braking efficiency as parts start to wear and an MOT check will point out any key areas for concern.

The driver’s view of the road is a regular failure point because it covers two common issues, cracks in the windscreen and worn wipers. If your wipers are causing smears on the windscreen or have obvious signs of damage, it will be classed as a failure point. Many drivers ignore small chips, but at any time this could turn into a large dangerous crack leading to poor views of the road. In many cases a chip can be quickly repaired to ensure you avoid any danger in the future.

The tyres are one of quickest wearing parts of a car, so without regular checking and replacements you could be at risk of an MOT failure. Many people check the tread depth which should be above 1.6mm, but you should also be looking for cracks, cuts, slow punctures and bulges to the outer sidewalls and the insides.

You will notice that many of these issues could be easily avoided with a brief MOT failure check and some quick and simple repairs. If you are looking for an MOT centre which can carry out fast and efficient servicing we have centres across Harlow, Maidstone and Dunstable.
