    Musty Smell from Vents at Start Up

    When I first start my ATS, I get a strong whiff of a musty smell from the air vents. It goes away pretty quickly, but that first puff of air is definitely old smelling.
    Anyone else smelling this? My ATS is garage kept, but I do live in Florida, so it's hot and humid.
    I got the car in December 2012, and have 9,000 miles. Mostly highway driving.

    I mentioned it to my dealer's service department at the first oil change, and he had the tech spray something into the vents, but honestly it was a cover up that did not last.

    Just curious if anyone else has this small issue.

    Thanks,

    I'd check the cabin filter.

    Has anyone figured out a sure way to get rid of the smell yet?

    My 2013 ATS has the same problem, it has been to the dealer 3 times for repair. They have changed the cabin filter and changed the programming on when the water condensation is supposed to be drained from the car (it wasnt draining on shutdown, instead it drained when the car was later started). If some one has finally figured out a way to solve this, any help would be much appreciated.

    I too, have had problems with the musty smell upon startup on my 2013 ATS. just got it back from the dealer where, of course, they didn't smell it, and even went so far as to reply in the service order comments that it was a pet urine smell. ( make it the customers fault, right?) Anyway, they sprayed some stuff in the cabin which didn't last 2 hours. Can someone please help? Spend this much money on a new car and have to deal with this?

    I am having the same problem and my car it's a 2014!! I was thinking taking it to the dealer but if all they do it's spray something on it it's not worth it. I will take it tomorrow to see what they say.

    I just took my 2014 ATS to the dealership (Tom Peacock in Houston) for the same problem. I've been noticing the smell for about the last 3,000 miles (I have 9,000 miles total on the car). The shop manager said this was a common problem with the ATS and it involves the A/C evaporator holding condensation after the car is turned off. He said there is a fix that involves installing a part that keeps a fan running to evaporate the condensation after the car is turned off (along with drying everything out and replacing the cabin air filter). According to the shop manager there is a service bulletin detailing this problem. I was starting to have serious respiratory problems and I mentioned the odor coming from my A/C vents to the doctor and he suggested that was the cause of my respiratory issues. We will see if a warranty visit solves $500 in doctor bills.
