Why Does My Car Smell Like Rotten Eggs?

There's nothing more unpleasant than opening your car door to catch a reeking smell. When a bad smell lingers in your cabin, your first instinct may be to find the source. But if the smell is familiar, like the smell of rotten eggs, it is probably sulfuric acid coming from your catalytic converter. 


The most common culprit for this spoiled smell is a bad catalytic converter. The catalytic converter is an integral component of your car's emission system that changes harmful engine byproducts into safer gasses before releasing them. When it stops being able to do this, all those gasses get mixed with the air, which can turn your car into a smelly mess.


If your catalytic converter is damaged, it will likely need to be replaced by a professional mechanic. In other cases, a bad pressure sensor can manipulate the catalytic converter to stop working. The best way to be sure is to have a trusted technician inspect it.


The Danger Of It All

Unfortunately, the smell you may be smelling is harmful to your health. It can kill you if it is strong enough. If you neglect the repairs for your catalytic converter, the damage can worsen and spread.


Once you have the necessary repairs done, the rotten egg smell will go away on its own. You can air out your car by rolling the windows down and using air fresheners, if necessary.
