My 2021 Colorado was smelling pretty nearly these past few months when I first started it up. I disinfected the HVAC by pulling out the cabin filter and spraying Lysol in through the intake cowel under the hood while running the blower on med-high. Smell is gone.
When I was in for an oil change, I asked my dealership to activate the Afterblow feature to help prevent this from returning. Attached is the literature they gave me explaining how it functions.
