Q5 has an odor caused by soundproofing cotton or carpets. Regularly open the windows for ventilation: After getting in the car, open the windows and turn on the fan to exchange air. Drive for at least 10 minutes before closing the windows and turning on the air conditioning. Bamboo charcoal bags: Replace them in time. Typically, a bamboo charcoal bag should not be used for more than 15 days, otherwise it will become a new source of pollution. Place fruits like bananas and pineapples in the car to purify the air: They should be placed in a location away from direct sunlight. Additionally, keep an eye on them to prevent the fruits from leaking, spoiling, or rotting. Prepare a small bucket of water: Add some vinegar and place it in the car. Try this several times, and the odor will gradually disappear.

I recently drove an Q5, and the unpleasant odor was quite annoying—probably from the new car smell or the AC. When it was newly purchased, the strong plastic and leather smell was particularly noticeable. After asking around among car-owner friends, many complained about it. Research suggests it might be related to interior materials, like coatings on seats and the dashboard releasing volatile substances under high temperatures, especially after parking in the sun. Additionally, mold or bacteria in the AC system can cause a musty smell when the condenser accumulates dust. This issue is also common in other SUVs like the BMW X3, and prolonged exposure may lead to headaches or nausea. I recommend airing out the car frequently or scheduling deep cleanings—the odor will fade over time.

As someone who frequently deals with cars, I've encountered many complaints about odors in the Q5. The root causes are often aging soundproofing materials in the interior releasing chemicals or bacterial growth on the air conditioning evaporator. The evaporator is prone to mold in humid environments, and when the air blows, the odor enters the cabin. Additionally, the glue and plastic parts in new cars may use high-VOC solvents during production, which slowly volatilize and cause persistent smells. During inspection, start by checking the air conditioning filter—replace it if it's dirty. Short circuits in wiring can also generate strange odors due to heat, but material issues are more common. The solution is simple: use the external air circulation mode to dehumidify or have the air conditioning system professionally cleaned at a shop. The cost is low but effectively avoids health risks.

After driving the Q5 for a long time, I noticed that the unpleasant odor is not only annoying but also affects health. Chemicals released by new cars, such as formaldehyde and benzene, can irritate the respiratory tract, especially making people with allergies more prone to dizziness. Why is this common in cars? It might be due to the interior materials not being eco-friendly enough, with cheap plastics volatilizing quickly in hot weather. The musty smell from mold growing on the air conditioner's evaporator due to condensation is even worse. It's recommended to open windows more often while driving and use the air recirculation mode less. Related environmental reports show that such issues are common even in luxury cars, affecting air quality. Personal experience: Regularly replace the air filter and use natural deodorizers like baking soda sprinkled in the corners of the car to help reduce odors.

Having driven an Q5 for several years, I've also experienced the odor issue. It's most noticeable during the new car phase, caused by the gradual evaporation of residual adhesives and solvents from the interior materials during manufacturing. The smell becomes more intense after parking in high temperatures, presenting a pungent mix of plastic and leather odors. Additionally, if the air conditioning system isn't properly maintained, dust and mold accumulation on the evaporator can emit a musty smell. In this aspect, the Q5 falls short compared to Japanese cars, as German designs often overlook environmental considerations. Long-term neglect of such odors can lead to bacterial growth inside the car. My suggestion is not to rush into changing cars. Instead, maintain regular ventilation during daily use, clean the evaporator and interior periodically, and the smell should mostly dissipate within a few months.

When I noticed an odor in my Q5, I thought it was the backlash of high-tech materials. The VOCs released from the new car's interior gave off a chemical smell, especially in summer when the air conditioning was on recirculation mode without ventilation. Installing an air quality app on my confirmed excessive benzene levels. Additionally, clogged air conditioning systems can breed bacteria, causing a musty smell, with components like the evaporator hidden behind the dashboard making cleaning difficult. Other models like the Mercedes GLC face similar issues, likely due to modern cars using more synthetic materials for lightweighting. The solution is straightforward: installing an in-car air purifier or regular ozone disinfection can effectively mitigate odor problems.
