We have tried everything to get rid of the smell. Just finally came across yesterday that it might be a problem in the vent or the air cabin filter, which my car does not even have. The smell is so bad people smell it on me after I get out of the car. Unacceptable Chrysler.

Had a musty odor coming from the AC when first turned on, then either smell goes away or I am getting used to it. The dealer used some new process (~ $100) to get rid of the odor which worked for about 10000 miles but now the odor is starting to come back. Other than that, I have had no other issues with this vehicle and it has a lot of power with the 5.7 Hemi. My previous vehicle (1997 Ford F150) never got a musty smell even after 11 years which tells me that there must be some design flaw since both vehicles were in the same environments.

Smells like a dirty diaper or stinky, sweaty socks when running the fan or the a/c for awhile.
