Hissing noise front passenger wheel well 2006 CTS-V, 105k miles
After getting home from work and getting out of the car I heard a hissing noise coming from ONLY the front passenger wheel well. Sounded like the tire was releasing air. I walk back out an hour later and I can still hear the hissing, air sound, although not as loud. My tires are run flats so it is difficult to tell if theyve lost pressure unless you drive it and you can hear/feel the increased rolling resistance. However, car drives fine and id never think anything was wrong if i didnt hear this after turning the car off. Doesnt appear to be leaking coolant or anything and if it is, its so little that it isnt noticable. Any additional thoughts?
