Consumer Description

I continue to smell a foul, moldy odor almost every time I turn on the air conditioner or heater. It has been a problem since I purchased the vehicle in August of 2024. I took the car back to the dealer from which I purchased it FOUR times. They finally “fixed” the issue by clearing out some tube. However, the issue has presented itself again. I had the cabin filter replaced last week to no avail. It still smells awful. I definitely cannot use the heater. This potentially presents a health issue and needs to be fixed.
