Why Does My Car Smell Like Boiled Eggs?
If your car has a strong odor resembling boiled eggs, there are a few potential causes to consider. One possibility is fuel system complications, as the presence of hydrogen sulfide in the fuel can produce a foul smell reminiscent of rotten eggs. Another reason could be due to the transmission fluid, particularly if it has not been changed for an extended period of time or if there is a leak in the system that allows for the odor to develop. Additionally, a malfunctioning catalytic converter may contribute to the issue, as it fails to effectively convert hydrogen sulfide into odorless sulfur dioxide. Finally, it is also worth examining if there is an electrical problem in the vehicle.
What could be causing the foul odor, similar to boiled eggs, in my vehicle?
There are several reasons why your car or truck may smell like rotten eggs. One possible cause is fuel system problems, as fuel can contain hydrogen sulfide, which has a foul odor.
