Something that is not covered by your new car warranty is that “new car smell”. While most people welcome that new car aroma there are those who are concerned that the odor is full of toxins.

“Everyone knows that cars are a major source of air pollution. But most people don’t know that it isn’t only what comes out of tailpipes that’s the problem, but what’s inside cars as well. “New car smell” for example, comes from toxic chemicals being released from plastics, foams and fabrics used to make steering wheels, dashboards and seats.

These chemicals are inhaled or ingested by drivers and passengers through dust and air, potentially causing allergic or other acute reactions or even long-term health impacts such as birth defects, impaired learning, liver toxicity and cancer. Since the average American spends more than 1.5 hours in a car every day, toxic chemical exposure inside vehicles is becoming a major source of potential indoor air pollution.
