# Service bulletin MYCOM\_091321\-3

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

My Communication for Detroit Connect Over the Air Issue Update. This is an update for the previously communicated Over the Air functionality issue on CTP1s. We are currently testing a solution for the issue that is affecting these CTP1 telematics devices. While testing is not complete initial results are promising. The solution will require a soft ware update which is currently planned for October/November.
