I would replace the cabin air filter, preferably one with activated carbon to absorb odors from the outside. I had a very bad smell coming from the vents of my 2013 Equinox. It turned out mice had made a nest on top of the cabin filter. I replaced the filter and sanitized the vents and haven’t had any problems since. More importantly, the 2.4l 4 cyl engine in 2010 to 2013 Equinox model had a problem with high oil consumption due to premature wear of the piston rings. Please check the oil level on a regular basis. My Equinox started using oil at 20 to 25k miles. The pistons, rings, and timing chains were replaced at 42k miles under warranty. The powertrain warranty is 5yrs/100k miles, I don’t recall if there is an extended warranty or recall for this issue. I started this thread when I discovered my Equinox was using oil. It’s long, but has some good info. > [@2013 Chevrolet Equinox 2.4 Oil Consumption](https://community.cartalk.com/t/2013-chevrolet-equinox-2-4-oil-consumption/89727): > > In the last 1000 to 1500 miles the Equinox has used possibly up to 1/2 quart of oil. Current mileage is 29500 miles and the next oil change is due at 30k miles. Evidently this is not an uncommon occurrence with the Direct Injection 2.4 Ecotec starting with the 2010 model year. I added 1/2 qt. and will track the level until the next oil change. The oil is changed every 5k miles with 29% to 35% oil life remaining according to the OLM. No noticeable oil usage between oil changes up to 28.5k mi… Good luck with your Equinox.
