Service campaign C2577
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.

The cellular antenna (5628702) is common between the new and old connectivity module, and should be inspected for reuse where appropriate. There is no GPS antenna needed with the new Prox 2 Connectivity Module, and can be discarded. This is an update to the previously submitted communication.
