2017 Premier with 46,000 miles. Out of the blue, the MIL light has come on. OnStar reports DTCs P0AEE, P0BD2, P0BDC are set. These codes persist after the proverbial 12 Volt battery negative terminal reset, and after 10 full on off cycles on the car. The latest recall software was installed on June 8th. Could this be just the calibration refered to in Service Bulletin 18-NA-064 needed? Other than the MIL light being lit, the car seems to be running just fine. I've never had a single problem until this.
