Service bulletins for the 2012 Chrysler 300

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.

90028382018-05-14. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. 04627731A$ - Trans Vent Hose The upper end of the transmission vent hose terminates with an open elbow. There is no cap on the end of the vent hose. This is intentional. Some graphics in StarParts may show a vent hose including a cap, but this is incorrect. The actual production vent hose has an open elbow fitting, not a cap. The elbow should be pointing downwards in the vehicle.~
