Ventilation system stinking :(

well if it’s in the ductwork after the blower, somebody’s going to have to go in there and git it.

You can check the intake side, and the cabin air filter yourself without too much hassle, sometimes gross stuff makes it to the top surface. It’s almost a straight shot from the intake vent near the right side windshield wiper.

 

How long have you had the car and have you checked the cabin air filter for mieces?

 

Have you looked at the Cabin Filter?

How many kilometres have you driven?

 

I'd definitely be chasing TOYOTA if that's the case.

 

Making ASSumptions can often lead you to the entirely WRONG place.

You really NEED to give them a chance to fix it.

And they really should give you a loaner.

 

For years I have smelled mold blowing from the vents in my 2016 Prius, 2010 Prius, and several Honda Civic before. I will say that after moving from smoggy Oakland CA to the Oregon coast I don’t notice that funk very often. Even in our cold damp enviroment. Just saying.
Chris, you are a very sensitive individual. It seems you lock on to things that bother you and focus on them. I get it, I do the same. Try switching from recirculated air to outside air (as long as you can stand it). Turn off the AC before you arrive and stop the car; the vents have a chance to dry out. Clip an air freshener on the center vent, but avoid any and all synthetic fragrances, like Glade, Febreze, etc. I use essential oils of spruce, lemon, and peppermint on a felt pad that clips to the vent. Finally, get out of the car and smell the ambient air. If it does not smell fresh, don’t expect your cars plastic ductwork to do otherwise. Good luck!

 

Have you looked at the cabin filter yet?
