To enhance the satisfaction of our customers, avoid further costs of litigation, and return focus to its core businesses, Mercedes\-Benz USA, LLC \(MBUSA\) has entered into a settlement regarding claims relating to alleged mold and mildew odors originating from the HVAC system in certain Mercedes\-Benz vehicles. As part of the settlement, MBUSA has agreed to offer sliding\-scale warranty coverage for certain vehicles diagnosed as having mold or mildew odors originating from the HVAC system. Although the settlement has received court approval, warranty coverage will not take effect until December 7, 2020, when the appeal period for class members will have expired. If the settlement takes effect, warranty coverage will include cleaning of the evaporator and replacement of the HVAC filters. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2020/MC-11031594-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2020/MC-11031594-9999.pdf) The document is the manufacturer's.
