Service bulletin N192218430

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

N192218430 - Customer Satisfaction Program. During service, certain vehicles equipped with OnStar (RPO UE1), may have received an incorrect and partially programmed/configured replacement OnStar module. This condition will disable certain OnStar features, including Remote Access (remote start, door lock/unlock, etc.), Connected Access (vehicle diagnostics, dealer maintenance notification, etc.), and Unlimited Access (Turn-by-Turn Navigation). The OnStar Safety & Security Plan (Automatic Crash Response and Stolen Vehicle Assistance) is functional. Dealers are to replace the OnStar module, program, confirm and register the new module correctly by pushing the blue button for confirmation with an OnStar advisor.
