# Service bulletin SIB640921

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's 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 \(EKMV\).
