Greetings everyone, I am aware that this topic has been previously addressed, but I want current information on the nature of this issue and potential solutions. I own a 2022 Corolla SE hatchback with 16,000 kilometers on it. The vehicle seems and operates well; unfortunately, the odor emanating from the air conditioning system is quite frustrating. This is what I have accomplished:
Replaced the cabin air filter. This is ineffective.
Operated the heater at maximum heat setting. This method is effective temporarily, but the odor reemerges after a few days.
3. Applied foam cleanser inside the evaporator coil enclosure from the passenger side. This generated a significant amount of brown liquid in the catch pan underneath the vehicle. The problem was temporarily resolved, but the odor is reemerging.
4. Odor neutralizing aerosol
5. Lysol
I have never had a vehicle that requires such maintenance, especially one with barely 16,000 miles. Ought I to bring it to the dealership? Is this a claim under warranty?
