Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Dear officer, from the beginning (2010 august, 0 mileage, mb E320) the car has a chemical smell. At first, I thought it will go away. However, in few months it became the most awful chemical smell (it is not mold, diesel fuel or exhaust). This extremely penetrating chemical(s) is/are coming from carpet. Venting/air-recirculation increases chemical concentration in the compartment to extreme levels. …”
