GM has traced the problem to water intrusion on connector C206 located on the left side of the dash. When water gets inside it can set service engine soon SES, SVS, APP and trouble codes P1125 and P2105. If you find water inside the connector, check for a leak at the top of the A pillar at the ditch molding. Reseal the opening. If the connectors are corroded, GM recommends replacement.
