The Need for Airbag Maintenance & Replacement—What to Do

Airbags are paramount when it comes to driving, as they are essential safety features installed in modern-day vehicles. They are pillow-like safety devices designed to protect you in case of a vehicle crash or collision. In the event of an accident, they quickly inflate, serving as a cushion for your body. That way, you will be protected from direct contact with the steering wheel, dashboard, or other parts of your vehicle that could potentially cause a concussion or break your bones.

As crucial as these implements are, many drivers often forget that these are fixtures that need maintenance too. In this article, we’ll share with you the need for its maintenance and replacement, so keep on reading to learn more.

How an airbag system works

It’s worth knowing that an airbag system consists of three main components—the bag, the impact sensor, and the inflation system. They all work together to inflate the bag and protect the occupant in case of an emergency. 

While the sensor sends the signal in a crash situation, the inflation system carries out the inflation task by releasing a chemical reaction between Sodium azide (NaN3) and Potassium nitrate (KNO3) and generating nitrogen. Ultimately, the bag made of thin nylon fabric gets inflated to protect the occupant and save a life.

Airbag system maintenance

Now that you know how an airbag system works, it’s vital to ensure that it’s in top shape and proper working condition. 

As much as possible, you want to make sure the sensor is working so that it will be able to provide the signal to your infiltration system to start working. Also, you want to ensure that your infiltration system consists of the right chemicals needed to inflate the bag properly! Beyond these, the bags must also not be damaged so that they will inflate and work as a cushion when needed. 

That is where airbag maintenance comes into the picture. The system will be professionally inspected and fixed as necessary.

Airbag system replacement

Some drivers ask whether or not it’s necessary to have the airbag system replaced. The answer to this is that it depends on the owner’s manual. While some require the airbag to be replaced after quite some time, others indicate that it needs to be regularly maintained. 

For this reason, it’s best to read your manual and see what your manufacturer’s recommendations are. Also, be wary of its parts over time, whether the bag itself, infiltration system, or the sensor—as these degrade and will cease to function well if not checked. The chances are high that some components are no longer working and need to be replaced every so often. But for the most part, it’s a good idea to have your airbag replaced entirely if it’s more than ten years. 

Keep in mind, however, that replacement costs depend on the make, model, and year of your vehicle. While they are quite costly in most cases, there isn’t a price you can put on saving your life!


At this point, you now know why there is a need for airbag system maintenance and replacement.
