Has anyone else noticed an odor in their 2011 Terrain? I have leather seats, but that's not the issue. Occasionally I get an odor almost like wet cardboard in the cabin. I even noticed it briefly the day I drove it off the showroom floor.
Did something crawl into my cabin filter and pee or ????

While something may have crawled in and died...more likely the odor is the result of "stagnant" water in the evaporator case...there are several Warranty fixes for this...

A Charcoal Cabin Filter may be installed

A kinked Condensate drain hose may need to be un-kinked

A Chemical "cleansing" of the Evaportator box may be necessary

and on some GM's enabling the afterrun blower is necessary depending amongst other things... the Climate of the area you live in.

Ours had it. They used the chemical to clean the condensor. We will see if it comes back. If it does come back I will have the dealership install an after blower to turn on the fan to stop the growth of the bacteria.

I think you meant evaporator...

as the condensor is mounted to/near the radiator...not inside the passenger compartment

Thanks,
I'm coming up on my first oil change, courtesy of the dealer, and will talk to the Service Mgr. about it.
Sometimes I even smell it in the garage. Hope it's somthing simple to fix because I like the smell of new leather and this is competing with it.

Got the oil changed and the dealer washed the evaporator box with Refrigiclean or something like that and enabled the blower afterrun. We'll see how that works.
I hate it when something covers the smell of the leather seats.

The de-odorizer smell WILL go away...it also kills bacteria growth which contributes to the first odor. Soon it should be a distant memory...especially with the afterrun enabled.

Let us know in a couple weeks !
