Official summary
On these Plug-in Hybrid Electric Vehicles (PHEV), the air conditioning cycles from cold to warm air while driving or while at a standstill. The vent outlet temperatures vary by 25 degrees Fahrenheit or more (38 F to 60 F+; 3 to 15+ Celsius) without changing any climate control settings. A difference may be felt in cooling power compared from left to right. In some cases, the air conditioning may have stopped blowing cold air altogether. A rattling noise may also be heard coming from the electrical coolant condenser (EKMV).

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.
