What Causes Odors Inside the Nissan Sylphy?
2 Answers
Typically, odors are only present during the new car period and will naturally dissipate after some ventilation. If the odor persists, it may be caused by a dirty cabin air filter, which requires replacement to resolve the issue. Below are relevant details: 1. When excessive dust accumulates on the car's cabin air filter or heating ducts, it can lead to fungal growth, emitting odors that are released into the car through the air vents. In this case, using an air conditioner cleaner to clean the vents or replacing the cabin air filter can solve the problem. 2. It is generally recommended to replace the cabin air filter every six months. Its main function is to filter impurities in the air, such as dust, odors, and ozone. When cleaning the cabin air filter, ensure to blow compressed air from the reverse side for cleaning, maintaining a distance of about 5 cm from the filter, and hold the air gun at 500 kPa pressure for approximately 2 minutes.
I recently encountered odor issues while driving my Sylphy, which mainly came from several sources. The plastic and glue smell when the car is brand new is quite common and tends to fade after a few months of use. However, if there's a musty smell when the air conditioning is turned on, it's likely due to accumulated dust and bacteria in the evaporator or filter, especially during hot and humid summers when odors thrive. Sometimes, materials in the seats and carpets release odors, particularly when the car is parked in the sun for extended periods. External exhaust fumes leaking into the car could also be a culprit—check if the window seals are aging. I recommend regularly ventilating the car by opening windows or leaving a slight gap when parked, placing an activated charcoal bag inside to absorb odors, and avoiding perfumes that merely mask the problem. While the Sylphy offers spacious interiors, its ventilation system requires maintenance. Odors can affect driving comfort, so timely cleaning is essential.
