That is why, in addition to taking into account the time and sudden changes that may occur between different times of the day, it is important to carry out preventive maintenance of the vehicle and replace those elements that have reached the end of their useful life.

In addition to checking the components that usually must check in the vehicle with the arrival of autumn, it is also convenient to know which elements suffer greater wear and check their condition, thus avoiding possible failures derived from the lack of attention and maintenance.

Generally, airbags, unless they used during an accident, are one of the parts that can withstand the entire life of the vehicle without any problem. However, in case the warning indicator on the dashboard lights up to warn us about any incident related to this active vehicle safety system, we will have to go to the workshop to review what may be failing and if it affects the operation of airbags in case of collision.

Check from time to time if the brushes are in an optimal state of use.

Wiper washer:

Above all, when rains are frequent during a weather station, it is important to check the condition of the wiper blades more frequently. If necessary, we can change them ourselves (click on the link to see our video YouTube tutorial on how to change the wiper blades ). To prevent a storm from surprising us on the road and our brushes are not up to par, making it difficult instead of improving visibility. Certain symptoms can help us identify brushes in poor conditions such as noises despite the moon and the wet rubber, poor cleaning, glass fogging on the outside, or irregularities in the rubber, among others.

The catalyst is part of the vehicle’s exhaust system.


As long as the vehicle is in normal use, the life of the catalyst can be between 120,000 and 400,000 kilometers. Once this last mileage has reached, its status should assess and replaced if necessary, since poor operation could cause pollutant gas emissions to exceed the limits allowed and approved for that model, causing us to obtain a negative result in the next ITV.

Although it is not mandatory, it is advisable to carry replacement bulbs in the glove compartment.

Lighting system:

It is important to regularly check the lighting system of our vehicle as the lights are one of the elements that accumulate the most failures during the life of a car.

It is advisable to check the tires regularly to identify possible damage.


The tires inevitably suffer wear due to factors such as the weather conditions, the weight supported, the different terrain on which it circulates, the way of driving, and even the state of the vehicle’s suspension system. It is a very important safety element, as it is the only way of contact between our vehicle and the road, so, conveniently, they are always in an optimal state and capable of responding to the maneuvers we perform.

Also, once five years have passed since its manufacturing date, it is convenient for a specialist to check them to determine their condition, and if they reach ten years of this date, it always advised replace them with new ones.

As you will see, several parts may have an expiration date on our vehicle. Knowing them and checking them frequently, we can avoid that the inadequate state of them supposes an inconvenience for our security or when passing the ITV in our car.
