Bulletin 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).
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
