Why does the Focus smell so bad?

The soft materials on the Focus dashboard emit a bitter plastic odor when exposed to direct sunlight. Here is more information about the Focus: Focus RS: The Focus RS is a new generation high-performance sedan developed based on the revamped European version of the Focus. The all-new Ford Focus RS will exclusively feature Michelin tires. Among them, the Michelin Pilot Super Sport (specification 235/35/19) serves as the standard tire, while the Michelin Pilot Sport Cup 2 (specification 235/35/19), known for its outstanding track performance, is available as an optional tire. Focus RS engine: The massive intercooler air intake of the Focus RS runs from the top of the bumper all the way down to the front lip, adorned with black metal mesh. The fog lights are directly embedded at the front of the front fenders without any embellishment. Two additional heat dissipation vents are added on the engine hood, and the vents at the rear of the front fenders indicate the car will have a powerful braking system.
When driving my Focus, I often notice a strange odor inside the car, especially when using the AC in summer. This is most likely an issue with the AC system – mold or bacteria growing in the evaporator, causing musty-smelling air to blow out. I recommend regularly replacing the cabin air filter and performing antibacterial treatments, otherwise the smell will get worse. Also, interior materials like seats or carpets can release chemical odors if the car is new or if low-quality cleaners were used, resulting in a plastic-like stench. If the ventilation system isn't switched to fresh air mode for extended periods, it can trap odors too. Don't just endure it – get a thorough inspection at a repair shop. Keeping windows open regularly helps somewhat. Also, check for water accumulation under the floor mats, as leaks can lead to mold and persistent odors. Bottom line: address it early for peace of mind.
When I previously drove a Focus, I investigated the cause of a strange odor and found it was mainly due to dust or dead insect bodies accumulating in the air conditioning vents, decomposing and emitting a smell resembling something rotten. This is related to maintenance habits—if quarterly AC cleaning is neglected, mold builds up and blows out foul air. It also depends on interior materials; some cheap materials release volatile organic compounds (VOCs) over time, mixing with humid air to create a stench. My personal suggestion is to run the external circulation for half an hour in hot weather to dry out moisture in the system. Also, check the exhaust system for leaks, as exhaust fumes entering the cabin can cause similar issues. If the problem persists, replace the activated carbon filter to absorb odors, but don’t delay too long to avoid affecting respiratory health. Remember to wash and vacuum the car regularly to keep it dry.
I've experienced strange odors in my Focus, with common causes being damp and moldy interiors like carpets or seats releasing musty smells. Coupled with an old and dusty cabin air filter that hasn't been replaced in time, blowing dust and bacteria throughout the car. Sometimes external pollutants like smoke and dust enter through the air intake, mixing into foul odors. It's recommended to ventilate by opening windows more often and clean the interior weekly. If frequent long-distance driving leads to food debris falling into crevices and rotting, the odors become harder to eliminate. Don't overlook small details; address them early to prevent bigger issues. Regularly replacing the filter and using deodorizing sprays can help alleviate the problem.
