INFINITI G37 persistent odor from AC and heater system despite deodorizing attempts on INFINITI G37

Some INFINITI G37 owners report experiencing persistent odors from their AC and heater system despite attempts to deodorize. These issues can stem from a dirty or clogged cabin air filter, which may contribute to musty smells. Many owners find that using aerosol deodorizing products specifically designed for automotive use, such as Meguiar’s Air Re-Fresher, can help eliminate trapped odors. Additionally, cleaning the HVAC system with mold and mildew removers is often necessary to address any underlying mold or bacteria causing the unpleasant scent. For ongoing odor problems, some owners recommend placing a plug-in air purifier in the vehicle to improve air quality. It is also advised to turn off the AC a mile before stopping to allow the system to air out and prevent lingering odors. Following these steps can help maintain a fresher and more pleasant driving experience.
