Why Does My Car Smell Like Rotten Eggs?

You start driving and you suddenly smell what seems to be rotten eggs. If it doesn't pass and you continue smelling it throughout your drive, this could be an indication of a serious problem. What you might be smelling is hydrogen sulfide, which is your vehicle's fuel. This chemical is usually converted into a odorless sulfur dioxide, so if you're smelling rotten eggs, there is more than likely a problem with the fuel system. 

Here are some of the issues that can cause the smell of rotten eggs in your vehicle: 

  • A faulty catalytic converter is the usual culprit when it comes to the smell of rotten eggs. The catalytic converter is the component that converts hydrogen sulfide, so if you're smell it, the catalytic converter isn't doing its job. 
  • A failing fuel pressure sensor or worn out fuel filter can also lead to a rotten egg odor. The fuel pressure sensor helps to regulate the use of fuel and it fails, it can clog the catalytic converter with an excess amount of oil. 
  • Old transmission fluid can also smell like rotten eggs if it begins leaking.

As soon as you notice this strange rotten egg smell and it lingers, bring your vehicle into the experts here at Premier Automotive Service. Driving with a bad catalytic converter can be harmful to you and your passengers because you can be inhaling toxic fumes. We will get to the cause of the issue and ensure that your vehicle is restored properly and quickly.
