Official summary
Some 2011-2015 explorer vehicles may exhibit an exhaust odor in the vehicle with the auxiliary climate control system on. Customers may indicate the odor smells like sulfur, or that exhaust odors are entering the vehicle cabin. This condition may be worsened when the climate control system is in recirculate mode and the vehicle is heavily accelerated for an extended period. Whether and to what extent any customer or occupant of a 2011-2015 explorer vehicle experiences the exhaust odor will be affected by driving habits, weather and individual sensitivities.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
