Have noticed the interior has the odor of spoiled milk or rotten cheese that comes and goes, sometimes in warm weather or freezing. Wife and I have sniffed everywhere but can't find any "hot spot(s)". Had the car deep cleaned which seemed to help but now its back again. Pulled the cabin filter, but it was fresh smelling no odor hint. Ran heater full blast and sniffed every vent but they seemed fresh no odor. I googled about Prime odors and one suggestion is the evaporator may be moldy/mildewed, and gave a suggestion how to mitigate it using Lysol aerosol (have not tried this). Another said water can get trapped inside doors and stagnate odors (sniffing each window opening was negative). We had an accident where driver rear panel was punctured, and had to wait parts before repairs so wonder if water could have gotten into insulation or matting which has molded/mildewed. Probably require body shop to tear apart and do look see and replace. Was considering taking to Toyota to see what they can do.
