We bought a NTU 2015 Chevy Colorado last weekend. Neither of us noticed the overpowering scent when we test drove it, but when we picked it up after detailing it definitively had a flowery odor. I though it might be Febreeze, but a friend (who has an acute sense of smell) doesn't think that's it. If DH and I missed it at the test drive, my next thought is the previous owner had one of those scented things that go in the air vents. The stink - for that is what it is to us - was so strong the day after we bought it that I could taste it by the time we got done moving things from the previous TV to the Colorado. So far, we have had the windows open as much as practical. I have a bag of activated charcoal in there. I've wiped all the hard surfaces with a mild cleaner. Last night, I left a fan going for 15 hours or so, with the windows cracked. It has started to abate, but it would be great to hurry it up - allergy season is beginning here, so our asthmatic selves do not need the added aggravation of whatever this smell is. Any other ideas? Definitely can't be anything that adds scent. I may put dishes of baking soda in it while it's parked at home, in addition to the fan and charcoal. BTW, so far, the Colorado is great, we are still in the process of figuring out the new configurations for cargo, etc. It's frustrating to have this weird issue.
