Bulletin Summary
Some vehicles may experience that the A/C does not blow cold air (blows warm air) due to a refrigerant leak. This is caused by a crack in the cooler pipe (HI) A (1) due to engine vibration. To correct this issue, the material and thickness of the cooler pipe (HI) A has been changed to increase durability (pipe diameter has been changed from 12mm to 16mm).
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.
