Why does the Buick Excelle have an odor?
2 Answers
The reasons for the odor in the Buick Excelle are as follows: 1. Odors produced by plastic, leather, or rubber products: These can generate certain smells, primarily appearing in new cars. 2. Poor-quality self-added decorations: Seat covers, steering wheel covers, anti-slip mats, etc. If the materials of these decorations are substandard, they can release large amounts of harmful gases when installed in the car, leading to stuffy air inside the vehicle and even causing odors. 3. Human sweat or garbage left in the car: Garbage left in the car can easily emit unpleasant smells. 4. Long-term lack of vent cleaning: If not cleaned regularly, accumulated dirt can mold and produce odors. Additionally, bacteria can grow and mold in the air conditioning evaporator, which is also a cause of car odors.
I've been driving a Buick Excelle for several years and have encountered unpleasant odors inside the cabin a few times. The most common issue is musty or sour smells coming through the AC vents, usually caused by accumulated dust and mold in the evaporator and ducts - especially noticeable during heavy summer usage. That new car smell of plastic or adhesives is normal when first purchased and typically fades within a month or two, but persistent odors may indicate aging interior materials releasing volatile compounds. Another frequent culprit is damp carpets or seats - for instance, when rainwater seeps through window gaps and isn't dried promptly, leading to mold growth. If there are leaks in the engine compartment (like oil or coolant), these odors can enter through the ventilation system. My advice is to first inspect the AC system when noticing odors, using antibacterial cleaners or professional deep-cleaning services. Maintaining a dry, well-ventilated interior is crucial, and don't ignore minor issues as they may signal deeper mechanical problems.
